The lower intake gaskets are commen to leak on the 3.1 and 3.4.They are made of plastic with rubber seals and always leak from the back of the motor right at the top of the trans,the plastic cracks and will blow the rubber seal but they leak at a slow rate so you may not ever notice a drastic drop in fluid.If you try to do this yourself make SURE that you put the push rods in as you have taken them out because they are different lengths.

As for the oil pressure seems you might want to check the idle it maybe to low or you might want to have the oil pressure checked to make sure the sendor and the gauge/light are working properly.

Hope this helps :lol:

My 2001 3.4L had a veeery slow radiator coolant leak for years - could never pinpoint the leak. It finally started leaking in earnest, altho I still almost went nuts finding out where it was coming from. About the same time, I started reading about it on the web.

I took some guy's suggestion and just bypassed the damned throttle barrel warming lines. Run fine so far for 3 days, no leakage, no overheating. Cost was a foot of hose and 4 hose clamps. I live in Alabama so I *really* don't worry much about cold weather performance.

Rather easier and cheaper than the official fix, IMHO.

well after running a few tests, i came to find out the ECT sensor was bad. replaced it and still the problem exists. only now i don?t have a problem w/ the oil warning light.
