BMW E32 engine car problems.

Car Problems tells about the basic BMW E32 engine car problems which arise while in service the car.
Your BMW E32 for many years of operation and run kilometers has saved up weight car problems and first of all because of engine M30: oil from the engine flows, a compression low, the layer pad of a head of the cylinder block has burned through, and the engine overheats... To put it briefly, car problems so many that it will turn out to replace yours М30 more cheaply, than once again to buy spare parts and to do repair.
M30 Name "the big six", it was issued long enough. It was used in a wide variety of bodies, among which: E12, E28, E23, E9, E3, E34, E32 and E24. I was a sign with the person having "sea" version M30 which has been specially made for use in boats. M30 is reputed as "devourer" of camshafts and layer pads of a head of the cylinder block. But it not car problems, and its owner. The camshaft is greased with an oil pipeline fixed over it with a cavity inside bolts which tend to a blockage oil adjournment. Periodic check and cleaning of an oil pipeline and bolts is necessary.
As M30 has the pig-iron cylinder block with an aluminum head, it rather sensitive to temperature changes. What to avoid car problems it would be necessary to watch closely cooling system. Replace a cooling fluid each two years. At replacement wash out system, it is desirable to remove a radiator and to wash out it separately, carefully having cleared it outside of a dirt and insects. M30 it is very sensitive during warming up and after a stop. So be convinced that the engine is heated-up to a working temperature before to press in a floor an accelerator. Keep in mind that the engine working temperature when the temperature index is in position of 12 hours is only cooling fluid temperature, instead of oil temperature! After driving on high speeds before blanking off, allow to the engine to work a little on the single. You can assemble at this time a junk in the car and clean sun glasses. At due and timely leaving М30 easily passes 500 000 km. Without serious car problems!

Than it is possible to replace M30 (BMW E32)?
It is possible to replace the engine 735i on M30 B30 or B35 from 7 ' (E32) or 5 ' (E34). Earlier variants М30 don't approach because of distinctions in oil filter and crankcase oil pan fastening that will create car problems at installation.
You can replace with other engine serially established on E32, for example, M60 v8 or M70 v12. But it will occupy more time and besides will create much car problems. For example, R6, v8 and v12 differ an arrangement of the vacuum servo of brakes and block ABS. Replacement М30 on V8 or on V12 demands replace a gear box. To change the car easier!
Engine S38 (3.6 and 3.8) from 5 ' M5 (E34) should rise as poured in since it is based on M30. Can arise car problems with the inlet pipe duct since it takes place on the left side. On the Internet there are examples of successful installations, but usually with S38 put a manual gear box. All based on M30 Alpina/Hartge/Schnitzer will rise without problems. If at you it is a lot of money, can look for the engine from E34 Alpina B10 Bi-turbo with 360 l.s./520Nm a twisting moment.

Jeep Grand Cherokee car problems.

Car Problems tells about the basic Jeep Grand Cherokee 1993-1999 car problems which arise while in service the car.
Serious car problems electric equipment at Jeep Grand Cherokee isn't present. However the car is equipped by various gages, drive gears and other — as a result there are everyones small car problems. More often to a detail wiring diagram refuses because of the decayed or broken wires or sockets. Last car problem, despite seeming simplicity of repair, can deliver many efforts, after all is often difficult to find straight off where what contact piece has fallen off.
The diesel engine of Jeep Grand Cherokee in volume of manufacture of the Italian company of 2,5 l «VM Motori» which established on the European versions whimsical and often creates additional car problems in a kind expensive major repairs (for example, only one hoses of the turbine manage in $400). The 2,5-liter diesel engine with capacity only 116 h.p. often if not always, it is compelled to work on a limit of the possibilities. For any the car of it, probably, would be quite enough, but only not for Jeep Grand Cherokee.
And the least problem it is considered the most reliable the 4-liter engine, on the design very similar to the motors established on the American off-road cars still in the sixties of last century. This pig-iron engine with chain drive gear GDG even maintains an overheat very easy! And if repair it usually costs not too expensively also is necessary to it — in many cases it is possible to keep within $1000. The most whimsical — the most powerful unit in volume of 5,9 l. It is very exacting to quality of lubricant, fuel, is afraid of an overheat and is inclined to car problems layer pads under an intake manifold.
Though if in the engine to fill in good fuel and in time to change oil, power units won't create car problems long time. Weeping epiploons become first sign of the worn out engine — at the 4-liter engine oil from a rear epiploon of a bent shaft very often flows, on what it is possible not to pay attention - after replacement an epiploon, in a half-year car problem can appear again. One more car problems Jeep Grand Cherokee — rather frequent failure of a gasoline pump. To solve this problem, on service sometimes suggest to cut the additional pump. Happens that the electronic ignition coil breaks, and in most cases out of operation there is the detail of the American manufacture established on Jeep Grand Cherokee in the first years of manufacture. Then it have replaced with more reliable Japanese.
For all tastes Jeep Grand Cherokee Almost all "Grandees" have the reliable automatic transmission demanding only timely replacement of oil and the sparing mode of operation. However, the drivers in this sense the most irresponsible — so worn out "automatic machines" on Grand Cherokee not a rarity. By the way, this off-road car equipped with several automatic transmission — it is considered the most reliable Japanese product AW4. Very seldom, but nevertheless there are off-road cars to a mechanical gear box to which reliability no claims are present.
The small part of Jeep Grand Cherokee made in the early nineties, had transmission without an interaxle differential (it was called Command-Trac and had internal number NP231). On cars with such transfer box at driving on asphalt the rear wheel drive should be connected only — if not to follow this rule, already shortly will appear car problems.
Periodically there are cars a transfer box of the old sample (249th series) with worn out viscose muffs. When viscose muff starts to wear out, it often blocks differential, even when it it is not required (especially at hot weather). With replacement it is better not to tighten, as in this case there is a strengthened deterioration of propeller shafts, the chain of a transfer box, bridges, SHRUS, crosspieces and so forth For prevention of this car problem can squeeze out from viscose muff silicone lubricant and then the interaxle differential won't be blocked.
Jeep Grand Cherokee suspender is made dependent both in front, and behind. And it is adjusted on comfortable driving. And it means what to pass turning movements on high speed by this car dangerously enough — it is possible to turn over. And still a suspender of first generation Grand Cherokee not such and reliable as can seem at first sight. To touch it it is necessary each two years (or approximately through 60 thousand in km). Sajlent-blocks of the bottom front levers usually fail. For preventive maintenance car problems instead of the standard sajlent-block is better to put the same detail from simple Cherokee which serves longer.

Car Problems: correct preservation of the car.

Car Problems tells as correctly to prepare the car for long parking. The snow frosty winter, long business trip, problems in a family can always create a problem with your car, demanding its long parking. What measures need to beundertaken, that for long months of parking in the car there were no failures and damages?
Performance of all series of measures on car preservation creates superfluous problems and financial expenditure.
In some managements for motorists the extensive list of actions which ostensibly is required to be executed before, car statement on a long-term storage is resulted. The car successfully and without serious consequences transfers storage under condition of performance of the following of a small series of measures on volume.
First of all it is necessary to wash up and dry carefully the car outside and from below, and also to make. Interior cleaning. To smooth out the found out places of corrosion, to process their anticorrosive means and to paint. All bolts and nuts from below the car for the corrosion prevention to cover with silicone lubricant.
The body outside is desirable for processing wax preserving structure or car preservative. The chromeplated parts to wipe a tampon soaked liquid mineral oil; instead it is possible to cover them with a solution 100g building bitumen in 0,5 l of a lead-free fuel.
The car should be hoisted on supports to unload tires, springs and suspender springs; from tires to exhaust air part, having depressed pressure in them.
At the engine to slacken a belt of a drive gear of the fan, to lower water from cooling system (if it is used special cooling fluid with low freezing temperature to merge it doesn't follow).
Densely to stop up with tampons from a fabric, soak oil taking away tube of the muffler and an air branch pipe of the carburetor (preliminary having removed an air purifier). This measure will allow to avoid car problems with corrosion of internal details of the engine.
To fill in oil in cylinders (as sometimes recommend) not necessarily as the work face of cylinders polished with piston rings, well enough resists to corrosion and practically never rusts.
Don't tighten a parking brake what to avoid car problems: for a winter brake blocks can tightly rust to drums and it is necessary to carry out extremely a laborious work on their removal and clearing in the spring.
The accumulator battery if it is quite serviceable and has served no more than 2 years, it is possible to leave on the place, having disconnected it from an onboard network and having removed tips of wires from plugs. If the battery in an unsatisfactory condition or simply old that in order to avoid freezing of its electrolyte has to be removed from the car and to store in a premise, it is better cool.
Also Car Problems recommends to unhook the bottom ends of absorbers from details of a suspender and to compress absorbers to the full, having drowned a rod in the case. Thanks to it the rod will be protected from corrosion.
If the car costs in garage, doors and a boot lid are better for leaving slightly slightly opened to give freedom to rubber sealants and to warn them rumple. It is possible to leave also in a luggage compartment of a pack of old newspapers. Thanks to hygroscopicity, the paper will absorb a superfluous moisture and will eliminate car problems with a condensate at temperature drops.
At car storage on the open area it is possible to cover it. A boot, however the boot shouldn't adjoin to a body surface not to spoil coloring. Is better to raise by means of crosspieces a boot over a body that similarity of tent has turned out.
The air layer will save up coloring and will relieve from superfluous car problems.

Car problems - how to learn problems of the ignition system of the car?

Car Problems will tell about problems in the car ignition system. Car the ignition system carries out two basic functions:
* makes a spark and distributes it in a certain order and time between car spark plugs;
* increases pressure from the accumulator battery to size, sufficient for formations in a spacing of a spark plug of a spark.

There are many various types of ignition systems.

The majority of these systems can be it is placed in one of three groups: the conventional breaker point type ignition systems (in use since the early 1900s);

the electronic ignition systems (popular since the mid 70s);

and the distributorless ignition system (introduced in the mid 80s).

Car problems in the ignition system occur because of problems in performance specified before functions. The problem can arise at car start. You turn starting engine key in the ignition switch, hear a characteristic sound of a working starter, but the engine "does not shoot" and isn't started. If process to continue long time, the battery will be discharged also it it is necessary to charge. In this case, if it is known that the fuel delivery system is serviceable and in engine cylinders normal degree compression the car problem consists in absence of formation of a spark on candles ignitions.



Fig.1. Car problems: schematic of a typical conventional breaker-point ignition system.





For search of a problem of the car in the ignition system with a typical conventional breaker-point ignition system:
1. Be convinced that all spark plug cables of your car going from the accumulator battery to coil, from it to distributor and further to spark plugs have no problems in isolation, cracks, damages through which the electric circuit can become isolated on the car or engine case. Check up - whether there are problems with contacts no high-voltage wires of the ignition system of your car.
2. Check up - whether pressure on spark plugs arrives. For this purpose remove isolating cap from a candle and arrange it on distance about 5 mm from the engine case. Thus isolating cap it is necessary to fix ignition the tool. At at turning movement of a key of start and starter work between the contact piece located in a isolating cap and the engine case the spark should slip. If the spark isn't present - a problem of the ignition system of the car in coil or distributor.
3. If after test of a isolating cap you were convinced that in the ignition system there is no car problem it is necessary to check a spark plug. Turn out a spark plug and inspect it: on a candle insulator there should not be cracks and black stains, spark plug contact pieces should have a spacing of the established size, to be covered by dry touch of light brown or pink color (it specifies in correct installation of firing point and absence of hit of oil in the engine cylinder).Also to check up a spark plug it is possible (if other ignition system of the car has no problems) as follows: insert a candle in isolating cap and place so that the thread on a spark plug would contact to the engine case. Engage engine start. If thus in a candle the spark, a candle serviceable is observed.
4. The problem of the car ignition system can be in distributor.To check up as spark plug cables are densely inserted into a cover distributor; remove and inspect a cover - whether there are no on it cracks, whether pure contact pieces on its inside; inspect the gear distributor (are disconnected or not contact pieces at rotation a rotor distributor, whether a normal spacing between contact pieces when they are opened, whether the whole wire in a metal braid which connects disconnected contact pieces to the condenser).If in distributor isn't present problems, but at rotation a rotor distributor with the removed cover by means of engine start on dead contacts the candle isn't formed, the problem of the ignition system of the car in coil means.
5. The problem of the car ignition system can be in coil or in primary resistor.In a case of breakage they should be changed.
