gas leaking in motor oil?

Question

i have a 97 chrysler concorde lxi.at first my fuel injection system was bad *replaced fuel line and fuel injectors*now the problem is this...i have white smoke that comes from my tailpipe *its not to be believed as a problem within the coolant*levels are good. my engine shakes and gas go throughs the car within minutes of driving. the smoke smells like gas and my motor oil has a strong gas smell also. what could be causing this to happen? how do i go about fixing it? expensive?thanks

Answer 1

IF your oil smells like gas, it sounds like you have major blowby. You will need to check the cylinder compressions. Blowby is when raw fuel is getting by the piston rings and contaminating the engine oil.
Check this asap, cause it will ruin the bearings.

Answer 2

First of all, drain the oil and see if it really is contaminated with gas. If so, it'll be thin and runny and will definately smell like gas. If it does, then you still have fuel problems. White smoke usually but not always indicates coolant leaking into the combustion chamber. White smoke can also be caused by brake fluid. I suggest you disconnect the hose that goes from the intake manifold to the vacume booster on the brake, the large round thing located behind the mastercylinder. You'll need to plug the hose or nipple at the manifold to keep from having one huge vacume leak. With the hose disconnected, run the engine and see if you still have white smoke. If not, you likely have a leaking seal on the master cylinder.

Answer 3

without knowing more i can make two guesses. 1 one of the injectors is bad or defective and is dumping fuel into the cylinder which fuel beinging so much thinner than oil will go right past the piston rings into the crank case. 2 the fuel pressure regulator which should be some where along the fuel rail is bad and is allowing to much fuel to reach the injectors which leads to the same problem to much fuel in the cylinders.

Answer 4

You may have a bad fuel injector or a bad fuel pressure regulator, a good shop can test them for you.

Answer 5

Yup- nothing to worry about. Most 2-strokes would accumulate unburned fuel in the exhaust system and would drain back into the environment. That is why many lakes have gone to 4 stroke only for outboards. You never saw it because it gets stirred up by the prop wash.

Answer 6

Blown head gasket.

Answer 7

do a compression test to verify head gasket condition....
