TR6 TR6 Timing Cover Seal

The current wrench party started with a good 1/32 stream of oil thru the timing cover seal. Got down to the point of replacing seal and sleeve and noticed quite a bit of difference between the "bad" seal and "new". Offending leaking seal has metal body with rubber inner, new is all rubber, obviously both with metal spring loop to keep pressure on the sleeve.

It occurs to me, that like most LBC parts, there are "better" and "not so better". I hate to get it all back together and have to do it again.

The PO rebuild was not long ago and seal was replaced, leaking soon thereafter.

I don't want to be doing this again anytime soon.

Any hints as to what type seal, from who, has worked best and any assembly tips to ensure a probability of success.

No clue on seals (used TRFs)- but be sure to check the crank spacer surface it runs on. If this is pitted or scored, you will never get a good seal. The replacements are available and not too many $.

Have new sleeve. Curious about the difference between the old and new seal. Hopefully, the PO did not replace the sleeve and a new one, plus new seal, will cure the problem.

Has anyone ever seen any sound deadening material on a timing cover. Mine has a bunch of "gunk" on it that PO said was factory applied. Seem kind of useless and not very "pretty".

Got my seal from BPNW
I think it has metal "within" the rubber coating and fit very well.
I agree check the running surface on the sleeve and replace if required, BTW that sleeve is a B to get off.
Make sure you use some good grease (assembly lube prefered) on the seal lip at reassembly.

I just did mine over the winter. I guess you'd call it a rubber seal with the spring "inside". I got it from Ted Schmuchaer https://www.tsimportedautomotive.com/ Ted has been a supplier for over 30 years and supplies parts to the Big 3. He doesn't list everything on his site but if TRF, Moss or VB sell it....Ted probably does too and at a cheaper price. Just drop him an email. No leaks so far!

you will find that the seal manufacturer has a signifigant effect on the design of the seal. Used to be all Chicago Rawhide seals had a metal body, same with National. Now some of them are coming rubber body.....

Yes that probably is the factory sound deadening material. Mine had it until the timing cover was hot tanked during the engine rebuild.
Don't notice any difference without it.

Thanks to all, will order a few from various suppliers and blindly pick, I think.

Have new sleeve, came off easily.
