Gas in the oil

[thenewmexican]

I posted an earlier thread about 1991 LS400 Dies after gas pedal pushed down.
Now. I have discovered, after checking my oil. That gas has somehow found its way into the oil.

How could this happen.

Thanks.

Do you havea ny blow by? Perhaps the unburn gas goes into the crank case via the rings.

Maybe Injectors leaking while the car's turned off?

What is blowby

Thanks for the replies.

Not sure what you mean by blowby.
One local mechanic said that he thought that the catalytic converters were clogged.
He said that there was barely any air coming from the tail pipes at all. He said that because the cats were clogged that the engine could not breathe.

Not sure if this would cause my problem.


Thanks again.

Blowby: The pistons and rings arnt sealing the combustion chamber enough and some gases "blow by" the sealing rings which presureises the crank case.

Do u notiice difficult start in the morning or backfire? Leaky injectors will do that too.

Thanks for the reply Lex.

Never difficult to start in the morning. Idles perfectly. Never back fires.



Thanks again.

It also sounds like you are running very rich from your initial post. Have you check your MAF yet?

 

[thenewmexican]

Yes. I purchased a MAF from a running vehicle. Made no difference.
I also checked the MAF with an ohmeter. All values were fine, according to spec.
68* 2k-3k ohms.

Lex.

Do you think it could be the ECU. Or plugged cat as someone suggested ??



Thanks again.
