I recently got my engine fully rebuiilt (2000 ls1). Eversince then, when my car warms up, (EVEN WHEN I START HER UP EVERY NOW AND THEN IN THE WINTER TIME) the oil pressure drops. I cannot remember to what kpa, but i will get that #. Secondly, there seems to be a gasoline smell coming from the engine oil, dipstick and oil cover. Is this normal??????????????????????

 

can you say ring blow by? or if you crank the engine without it starting you will have some leak down. or check the crank case vent system

 

I had a gas smell on an 89 Formula 350. Turned out to be ECM. It was firing injectors excessively, flooding the engine. When I pulled my dipstick, it was about 1/4" too high. Oil reeked of gas.

A rebuilt ECM from Checkers and an oil change and it was good to go.

 

thanks for the insight, but I am not familiar with the term ECM. Can u elaborate a bit?
thanx!!

 

On the LS1 cars, I believe they actually use the term PCM for Powertrain Control Module .

I dug thru my handy dandy web link to TSB's , but did not see anything -

Perhaps I missed something.

When I posted about my experience, one guy said he had seen it happen with 4th gens, but he didn't specify if LS1s or LT1s.

I had a problem with fuel diluting the oil, when my car was running rich, and I accidently put the pcv in backwards... So not only was fuel getting into the oil, but the pcv couldn't pull any vapors out either...

I fixed both problems at the same time, and it hasn't happened anymore.
