Oil leak when car is on slight slope


Im not fully conversant with Turbos , but I would hazard a guess from memory that there is an oil feed from the engine to the turbo to lubricate it. I would think that the oil sump in the turbo has a seal at one or both ends. When the car is level, the oil doesn't reach the level of the oil seal, and therefore doesn't leak. When the car is on a slope, the oil will level itself out and probably be above the oil seal and then it leaks. Check if the leak occurs only when the car is pointing uphill or downhill. It may give you an idea as to which end seal is leaking.

My 2002 vw jetta 1.8 turbo is smoking from the engine and leaking oil. whats the problem?


The smoke is due to the leaking oil. there is a common problem where the oil hose that feeds the turbo leaks, and drips on exhaust. Open bonnet on cold engine and clean the rear part using degreaser of sprayer, start up the engine and let it idle while checking the rear . for better results i usually pull the car up on a white sheet of cardboard or paper so i can see where it drips or splutters the oil on top the paper. Turn off car about 10 minutes in and check under the car. the area where you see oil will tell you where to investigate further. Another common VW problem is the tappit cover gaskit that leaks from time to time. Remove plastic engine cover and have a look

My 2002kia is blowing out oil really bad all underneath it could it be a clogged pvc valuve wher is it located


Check the oil pressure switch first, just have the car idleing & watch the switch to see if its leaking. if not look for the clean part as a bad oil leak will wash the motor where it is leaking. common mistake people make when diagnosing oil leaks is to look for the dirty parts but you need to look for the clean part.

My 04 VW Jetta blew thick white smoke from tailpipe after freeway drive. No indicator lights came on, all oil leaked out (after smoke started)... is this engine or could it be just the turbos? Right...


A new turbo charger is about $340, but you can buy the bearings and seals and rebuilt if yourself for about $100

It is not hard, and it does not take long to do.

I normally do not bother with synthetic, but with a turbo charger, it might be worth it. What really seems to ruin turbo chargers the most is not letting them cool off before parking.
Once you turn off the engine, there is no longer any cooling, so the build up heat will burn up the oil and seals.
Run the engine for at least 5 minutes below turbo levels, before shutting down the engine.

My 1995 C220 is losing antifreeze, but I can't figure out where. It has been pressure tested.


You may have a small leak in the head gasket. Have the plugs pulled and inspected for signs of coolant incursion into the combustion chambers. Also check the crankcase oil on the dipstick to see if any milkiness is visible and the coolant overflow for any signs of oil mixing with the coolant. If this is the case, eventually you will have ignition misfiring when cold until heat buildup rids the plugs of coolant.

What can cause the turbo to leak oil into the intake


The seals going bad. It is not uncommon to have Turbo seals go bad after awhile. But a little oil leaking into the intake is common, but if the leak is bad enough then a turbo rebuild will be needed. You can read more about it here.

Oil leaking from car. always have to put in 2


Well go find a clean driveway to park on for a while and let it idle. See if there is any oil on the ground and what part of the engine it's underneath if you see any. There are other places you get loose oil if you dno't see it leaking. The valve guide can be worn and let oil directly into the cylinders, If it's turbo-charged the turbo can leak oil into the intake manifiold and burn it in the engine but this problem usually creates a lot of smoke from the exhaust. The rings on the pistons can be worn out and are not scraping the cylinder walls like they should and letting the oil get on top of the piston where it burns while running. Check your tail pipe and see if the inside of it is oily. Doing those things should tell you if it's a leak or if the oil is being burned. Then you can ask further questions about the problem based on what you learned from this suggestion. LUCK

there is a seal on t hr breather box that could be leaking if there is oil across the oil pan if it is only on underside of car then the turbo return is leaking that is most common probably 10 dollars for gasket and seal and easy to change

I have black smoke when putting pressure on the engine anfd there is no power, checked vgt, ok turbo sounds ok but get a burning smell of oil in cab, but no leaks on valve covers etc 6.0 engine


check the air cleaner if it is plugged up it will cause the engine to run rich. check the EGR valve if it is coked up with carbon this will cause smoking under load this is a common problem. double check your turbo for excessive oil on the intake and exhaust sides note it is normal for the turbine to have slight play it rides on cushion of oil while running. also check with you local dealer for computer updates there is a re-flash for the earlier 6.0s with fueling issues.

I have a 1995 lumina with the 3.4L engine. I have a slight oil leak and from the looks of the bottom of the car it has been leaking for quite a while. I just bought the car so i wouldnt know. But the oil...


SERIOULSY!!!!! first, go to a car wash, steam clean/ shampoo the entire engine (taking care to avoid directly spraying electricl components/distributor) then drive for about 10 km (6 miles) and look underneath the hood and see where the oil is possibley leaking from. Remeber, oil can leak down from the top and make somethine below it look as though that is where the oil is coming from. Also, the fan air can blow the oil from front to back making the oil drip from all over.
Possible places that oil leaks come front: top = valve cover. front = cam shaft or crank shaft seal if from the rear = could be rear main seal.
