Rear Main Seal Repairable?!
So I drilled tapped the block this wknd, but missed the two 10mm bolts by the flywheel. I didn't realize there was an access panel that hid them! That cracked a piece of what was holding them.

Well here are the pictures

What are my options? Do I weld it? Is it safe to put back and with sealant and not leak?

Um...I hate to be the bearer of bad news...

You might want to invest in some JB Weld and see if you can salvage that until you find another block.

Its the rear seal housing and can be changed but ya gotta pull the tranny and everything off..... a pita especially with all the other stuff off but deff doable..... maybe someone can chime in and say weather u can put it on after the upper pan is on but im guessing no or that it atleast would be a bad idea

Actually..... u already have the.crossmember.and.everything off...shouldnt be too bad to pull the tranny just a little more messy. i.think i got.a spare housing kickin around you can have unless someone closer can hook u up faster

Use an engine cross brace to support the engine or a cherry picker - pull the trans - replace the part. Use a new Nissan rear main seal 12279-18V00. If you need the piece that holds the seal that broke get 12297-53J00.

I have plenty of spares that you can have for free, but I'm in SoCal.

When you put it all back together according to the FSM.

Do it once - Do it right. You will only get out of it what you put in.

I just want to thank you all so much. I never expected this but when shit happens I know I could rely on this community.

See if you can borrow a Engine support bar that holds the motor in place then you can do your thing.

Yes, sometimes we all make mistakes. God knows I have. But then you gotta just look at the situation and take your time to get it right after the problem and get it right second time around. Good luck.

Its just a rear main seal housing. Put a wanted ad on the forum and im sure someone has one that they can send you. Not a big deal other than pulling the trans off. Do not weld that or use jb weld. Waste of time. Get another housing and seal and call it good.
