Just did. Sprayed corner of gasket and revd up. So definitely have a leak either on the base gasket or seal on flywheel side
Thanks a lot fellas.
Yep, the seal on on the flywheel side is blown on my 254. currently waiting for them to arrive. Glad you found the air leak.
There are three tapped holes near the mounting holes on the seal holder. You can use the seal holder mounting screws, thread them in those other holes and they will push the seal out part way. They will NOT push it out all the way so don't force them after the seal starts moving. Treat them like you would head bolts and tighten each one a little more in series so that the seal is pressed out evenly. Usually once they are started they will pop the rest of the way out with a pick or similar tool.
Yep. I got mine out last night doing that trick
I hope I ordered the right seals though. the one that popped out of my 254 didn't have a metal outer sleeve the ones that said they were for a 254 have the metal sleeve on them.
