When I did mine i had to use rtv to fill in the gaps on the rear left and right of the mating surface. (by the flywheel).

Also, I had a hell of a time getting the rear lip of the gasket to seat properly on the oil pan, the first 2 times the rear lip was not seated right and i tightened it down and distorted the gasket, so on my third gasket, I stuck dabs of Rtv randomly around the gasket, tightened the gasket on with the bolts (no oil pan) then after it dried removed the bolts, put the pan on carefully, then retightened. Watch that rear lip.

And if you dont dab rtv in those two rear gaps in the mating surface it will be quite apparent after you have everything together and start it up.

Id assume yours should be similar with the rubber gasket.

If you buy a good gasket, you really shouldn't need any RTV at all.

When I did mine three weeks ago, I used the Permatex gasket sealer, only to hold the gasket in place until I got the pan mated to the engine. Then tightened it down and all was good.

The gasket I used was the rubber type with what appeared to be some type of stiffeners built into the long sides of the gasket to keep it straight.

I think i had a fel pro gasket when i did mine. Same thing, both the left and right sides were stiffened, but the front and rear parts are verry rubbrerish.

I had to use RTV in the rear corners, and I think the instruction to do so came with the gasket.

Just check to make sure the gasket dosent specifically call for rtv and you should be fine. if it wants you to seal soemthing with it there would probably be a note with the gasket saying "IMPORTANT: Use rtv at so and so."

Either way its a pretty basic job. but it looks like it might be best to stick the gasket to either the pan or the engine beforehand to keep it aligned.

IIRC, there are four spots where the factory used a dab of silicone.

I tried to replicate that when I installed mine.
