O-ring for oil pan gasket

[Mertz]

I’m getting ready to reinstall my oil pan and have new gaskets. I know to keep the ones over the mains a bit short so they will meet the main gasket correctly. I don’t understand the instructions which say to cut the o-rings and place them near the mains. Do these go in the gap between the two gaskets or in the corner?  I had planned on some sealant there. I used gasket cinch on all my gaskets.

Your are only replacing the two pan side rail gaskets plus the two thick cork end gaskets.

An oil pan re-seal job.

Those stupid O-rings never used to come in an oil pan gasket set.

Now there is an area that uses two approximately 1" long by 1/16" diameter straight  rubber strips.

These two straight rubber seals fit into a straight groove on each side of the front of the engine aluminum seal plate. These two  rubber strip seals are used to seal this aluminum plate against oil leakage between this plate and block.

This aluminum plate is what the front oil pan and cork gasket seal on.

For some silly reason gasket suppliers want you to cut the O- rings....straighten them out and fit them into the groove on this aluminum front oil pan sealing plate.

To even remove this plate both the oil pan and timing cover must be removed to remove said plate to replace the two seals.

NOT part of a oil pan gasket re-seal job!

I need to take another look since I have both the motor mount plate, timing chain cover and the oil pan off. A picture would help a lot.

Not wanting to dispute the replacement procedure, but I fiddled with this a few weeks ago to jog my memory.  The timing cover does not need to be removed, but two (or three?) of the cover's bolts do thread into that seal plate so they have to come out.

You are correct...to remove that seal plate all three fasteners...(the two slotted screws and a  hex bolt) are accessible when the pan is removed.

My loss of memory!?

That hex bolt and a tapered slotted screw also need to be removed to remove the motor mount plate. To get to all the bolts to remove the motor mount plate you have to remove the pan, timing change cover and timing chain. 

 

Thanks for the picture. I don’t think I’ll mess with the o-ring seals. The gaskets should cover the hole.
