GM or fel-pro what oil pan gasket is better? Its a 1 piece rear main block.

 

fel pro is all i use. look into getting a one piece oil pan gasket, lot easier and better to install.

 

So the fel-pro is better than the GM gasket.It has to be a 1 piece gasket anyway its a 89 roller block.I read that the fel-pro is thicker than the stock gasket and could cause clearence issue.Is this true?

 

I got the fel-pro one piece. There were no problems here.

 

I had no problems with clearance using the Fel-Pro oil pan gasket.

 

Both you guys have roller blocks w/1 piece rear main seals?

 

the block has nothing to do with it being a one piece or four piece gasket and you can use either one on any block, long as the it works with your dip stick location.

 

I read in a couple of old posts that guys that had older style non roller blocks when they used the fel-pro 1 piece instead of the 4 piece it didnt crush as much and caused the the pan to hit the driver side exhust pipe.The block kind of does matter older 2 piece main you could of use 1 or 4 piece gasket. 1 piece main you could only use a 1 piece gasket.(not a flame)I just wanted to know if the gasket for 87-up blocks crushed enough.

 

I don't see why a 1 piece wouldn't work on your 89. I have a good 1/2 to 5/8 inch between my exhaust and pan. Of course me having 2 cats might make a difference.

 

the block does matter so that you get the proper gasket set, ,but just because its a 1 piece rear main does not mean you must use a 1 piece pan gasket, the only thing that must be a 1 piece is the rear seal, believe me i built a 1 piece rear main motor with a 4 piece cork and rubber gasket set.

 

i've used one and four piece gaskets on new blocks and old blocks and ther is no differance. if the pan hits the y pipe move the pipe, there's a lot more movement in the exhaust and less control than a machined part. tell me why the block matters, other than dip stick location if you use a one piece gasket. buy the gasket to fit your application either one piece or four.

 

OK guys thanks I'll just go with the Fel-pro
