Loctite 518 Anaerobic Gasket Maker
20 + years ago, replaced the oil pump due to an oil change problem!
With the timing cover off, needed to seal the cover back on.
A friend had given me a tube of GM sealer for auto transmissions.
This red sealer was used here and elsewhere and is still on the cover.
If you need to remove the unit, it will shear off with some light tapping laterally on the cover.
Once the cover is off, the sealant will peel straight off with almost no resistance, this being observed from being used elsewhere than my timing cover.
It peels off almost like silly-putty, no residue left over.
The question here is whether Loctite 518 is a similar product to the unknown GM?
Would like to use it for the primary chaincase cover, in lieu of a gasket, as have had this cover off more than a few times.
The chaincase cover has two locating dowels that would prevent shock/shearing the bond to break using the wrong sealer?
The chain cover is still leaking primary oil even after a new, thicker gasket installed.
The drain screw and the chain tensioner screw seem to be leaking for lack of the correct fibre washers?
Have tried everything under the sun to rectify the leaking , it's not gearbox oil- that problem was fixed.
Would like to duplicate that magic GM sealer that's easily un-done, any help appreciated!
