91 Chevy Lumina Euro 3.1 litre
91 Chevy lumina euro stated to leak oil. Looks like the oil is coming from the left and rear of the engine compartment. Any ideas

Yep, most likely, I've done three of them now. Look directly under the throttle body. There will be a plug there. You will have to remove the throttle body, etc to get to it. You can replace the O-ring, but it will eventually leak again, I just blue RTV that sucker and it never leaks again!

I don't know about your oil leak but I feel sorry for you it took me 2 days to put a thermostat on a 3.1 and it was'nt fun man. every mechanic around here has told me to trade it in asap and in the last post i made about the thermostat on the 3.1 alot of people told me they had nothing but problems out of them so........

General info..We have several customers at where I work who have cars with the 3.1 in them and have 150k-200k miles on them..Yes the intake gaskets have had to be changes, along with the oil pump drive o-ring, but other than that, they've lasted well, and performed well for these customers.

I have had 3 such cars, two were 3.1's and one a 2.8. Never had any problems with them (major) 120k on the 2.8, 170k one 3.1 and my current work car 140k. All cars were running strong when I sold them. T-stat, my current '91 3.1 is easy! I have owned many work beaters---and for the power they produce along with the fuel mileage--you can't beat the GM v6's. And the 1990 and later bodies really hold up well--my '91 berreta does not have a spot of rust on it and paint is original--and I run it every winter here in the rust belt--in fact it still has the original exhuast system on it!
