do 3.3L engines have a common oil leak?

so i've been workin on my car alot lately, and have spent a lot of time under the car. when i changed the oil i wiped down the oil pan and everywhere else i saw oil. the bolts in the bottom of the oil pan were pretty loose so i tightened them and the valve stem cover bolts were loose up on the top of the engine so i tightened all of them. the car is still leaking oil (a small amount) and i dunno from where. i went back under the car a couple nights ago and the whole oil pan had a light coat of oil all over it, i've tried back trackin the leak to see where its comin from and i just cant. it seems to be higher than the oil pan gasket...but its goin thru maybe 1/3 quart of oil every 3 to 4 weeks. since ive become a member to this site i realize there are some very knowledgable people when it comes to intrepids so i was hopin someone could tell me if they know of common leak points on the 96 -- 3.3L engine. btw...i got 98000 miles.

Its hard to tell sometimes where it leaking from because when your driving the wind blows it all over but i bet the oil pan gasket gasket is shot.

Im hoping to replace mine the beginning of next month along with a laundry list of mods i have started.

Oil Pan Gasket, (Mostly from the front where the Aluminum Front timing cover meets the oil pan and block) Valve cover gaskets, Front Oil Crank Seal, and Rear Main.

Valve cover gaskets were my big leak, that and the trans cooling lines at the radiator but those aren't oil.

i did some more scoping around and found a small puddle of oil under the pully wheel attached to (i think) the crank. Its the big wheel in the center.

Thats the crank pully. So from what's been said already it could be the pan gasket or front main.

Hey guys, can you change the front main on the 3.3 without dropping the crank?

It can be done with the timing cover still on the car, and if you can get it off thats the quick way. If you cannot remove the seal with the timing cover still on then you will have to drain the coolant, drop the oil pan a couple inches(might as well drain the oil out), pull the accessories, and finally pull off the timing cover. The good news is that you will be able to see the condition inside the engine and replace the timing chain if it needs it. The bad news is that its a helluva lot more parts to pull off. Moral is, if you can get the seal out without pulling the cover, thats the way to go. No crank dropping required either way.

My best guess is that you need to replace the oil pressure switch.

I had the same problem ( small oil leak ), and after I changed it, it was gone ! : )

The oil tends to come through the dried out threads from the oil pressure switch.

Doesn't take much time to change and the part is not that expensive.

Good luck
