Retighten Permimiter Bolts
 

Hi,

I have a issue with a leaking rear main seal not from the crank but from the outer bottom edge where the case joins. I am about to take the engine out to fix this again (second time) and wondered if I should tighten the perimeter bolts around the seal.

The concern is that the sealant has hardened and that changing the torque of the bolts will effect the sealing properties, in a bad way.

Any thoughts?

Thanks

Well, youre already leaking so you cant do much more damage and if you dont try it you ll never know

Good point....but it could leak more....!

I am inclined to believe the same thing.

How bad is the leak? Are you sure of the source?

Don't do it, you will break the studs and then you will have a hard time getting them out, this could require splitting the case again.

Ok thanks John and MCA,

The leak happened after a full rebuild when I had the engine on the stand to replace the clutch, a year later, I changed the seal but immediately had a small leak from the bottom of the seal at the seam. This was only from the oil that seeped to behind the seal while the engine was sitting. So I changed the seal again....all seamed fine. Until it was started. Only a small drip, seams to be when it sits rather then when running.

It could be from the crank but until drop the engine I have no way of knowing. Just getting my optionsready before dropping the motor.

Thanks

Mark......
