Rear Main Seal Pic and ??

[chattfj40]

Well, after having someone install the 41/Orion that Poser built me because of time constraints, my rear main seal started puking oil after about 2 weeks so after talking to a few different people DSLTOY and I took everything back down and changed out the seal with an OEM toyota seal. We did it the way Poser describes (dropping the oil pan) which was not the way the shop had done it.

This is what we found with the one the shop had used. My question is what you see in the pic indicative of a seal damaged during install or a bigger problem with the crankshaft? The seal went in easy w/o binding at all, the pilot bearing felt brand new, and the #4 Bearing Cap also looked very good.

I was told at the original install that the line bore on the motor was off and that the crank moved fore/aft "a lot". I received differing opinions on what was possible to even see/measure with the crankshaft in the motor so I'm bringing it here for another opinion. I'm not looking to go after the shop that did the install if they fawked it up, I just won't go back...

Also...that combo is heavy! and getting it back in a late model 40 with a track bar and no tunnel mods is a PITA...whew I have a few more pics of the bottom end, but nothing that really stands out. Let me know if you want to see anything...

Looks like installation damage, have made the same mistake in the past myself.

Looks like it got tore up on the install to me also.

i have a leaky rear main seal as well. I have purchased a new oil pan already because mine is pretty rusty anyway.

So if i drop that to replace it, i can access the seal pretty easily?

I am not real mechancial but i am willing to try. Pointers are welcome.

You have to pull the tranny/transfer and the flyweel to put the seal in it's one piece so everything comes off the back of the motor, Larry

thanks for the opinions. Seems the few that posted up all agree that it was install damage. Of course, I won't know for sure for awhile, but I doubt there's anything wrong with the bottom end of the 2F

I guess I just lost what I've considered the "best" LC shop in the area. Well they are the only LC shop in the area and a TLCA associate member as well. figure it out if'n ya live near here. I've had some minor differences in the past over things, but if a guy's been in business for 20yrs and can't install a simple RMS correctly...Fawk him...YMMV, but I won't be going back...
