Rear main seal install help.

[zandrew]

Does the rear main get fipg gasket around the flange itself or just where it meets the oil pan? There was no fipg on the old when I removed it but it seems to be lacking something.

If this is a 1.8 apply a thin film of oil on the inside of the seal that goes over the end of the crank shaft. Learn from my mistake the nice plastic disk keeping the rubber part of the seal in shape is the installation tool. So unless you would like the new seal to leak use the tool. Don't do like I did remove it and throw it away. I'm not sure what fipg is but if its a gasket making material it needs some between the oil pan and the bottom metal edge of the seal. Good luck really not a difficult job just clean the surfaces and use the tool.

I couldn't figure out how to use the tool on 3L so I cut a soda bottle

Found this pic, I think it's from 2.7T but same idea


I followed whatever instructions came in the paper packet, or whatever is posted online at seal maker sites like Reinz.
Stuff like, area must be dry (oil was drained and area was cleaned), install dry, don't turn/crank for 4+ hours (I let it sit more), etc.
It didn't say to pre-crank, but I did. Instead of applying hard crank torque with starter like you normally do via key ignition, I slowly gently turned it over via the front crank bolt with a breaker bar. IDK if one is preferable to the other, as the PTFE seal somehow deposits a layer of lubricating film.
IIRC it also said to install it to a depth different from before, and I tapped it into the flange around 360deg with punch and mallet. Lightly.
I was scared to mess it up, but I don't think it leaked.
Maybe it was $8, Corteco or something

Mine is a 1.8t and I removed the install tool and got mine to go over it just fine. It did not fold or anything. Still makes me worried and I guess I will check the local parts store and see if I can get another and use the tool this time.

The motor is out and is getting completely rebuilt. I removed all gasket residue and cleaned and dried both sides before installing. What had me confused is the older 058 style actually has a gasket that goes there. 06A does not so it had me wondering if I need to use fipg (formed in place gasket which is what Toyota calls it) on all of the mating surfaces or just the surface between oil pan and rear main.

Thanks
