I'm getting ready to swap oil pans on my 617.951 replacing it with an earlier pan for clearance issues. The picture shows the rear rope seal on the original pan. I'm only replacing the lower half of the seal, leaving the half in the block untouched. The specifications call for cutting the seal 1mm proud. As shown the rope seal in the original pan is about 1mm "un-proud" which I'm taking as evidence that when the engine was last assembled all the "excess" was on the block side, thus indenting the seal on the pan side rather than having both sides flush.

My question is, should I cut the new seal flush allowing the existing block-side seal to compress the new seal the required amount or follow the specifications and leave it proud 1mm?



Sorry about the picture, it is my cheap "garage camera" that does pretty good for normal stuff but has trouble focusing close.

Don't try and second guess the FSM on this one - I don't know how those role seals behave but imagine if they shrink after a while and you haven't got that extra bit...

This thread might help -

Don't leave that there - I'll take it to bits!

In my not so limited experience... failing to remove the block side seal, is foolhardy. go ahead and loosen up the crank, and replace both sides of the seal. leave both sides proud 1mm, and do it right.

ok so both sides of the seal CAN be replaced with the crank/engine/kitchen sink still in the car? I got someone that wants this done locally.

Would just doing the bottom stop a huge leak?

Now that you read the link ARMY posted in post#2. here is another good thread to read on replacing the rear seal.

I really do not see how this can be done while still in the vehicle.
If you can accomplish this, be sure to do a DIY with pictures.
