Rear main seal sealant?

FSM calls for loctite 518. None of the parts stores around me carry loctite brand. What is best to use?

On which bit?

I've always used the later (1996-up) one-piece moulded gasket (dry) and dropped the new RMS in clean engine oil before I started tearing things down - let it soak until you install it.

FSM says to put a touch of RTV on the ends of the seal, but I've not bothered - that's why I soak it.

Haven't had any trouble, just don't install the seal backwards.

FSM calls for a anaerobic sealant, loctite 518 which i found in permatex brand part number 51813

I know - where does it say to use it? That's the part I don't recall (often, the two-piece moulded rear mains want it between the ends of the seal halves. The old "rope" seals just get trimmed and run.)

I don't like to do it, because I don't know if it's going to get into anything or not. Even if you use just a pinpoint, you can't quite be sure where it's going to end up (but it usually stays put.)

Ergo, I modified the procedure slightly. I've done it the way I've described a number of times now, on different vehicles, with no ill effect.

Although, LocTite #518 Gasket Eliminator is good stuff - it's saved me on jobs where I couldn't find the gasket I needed (I used to be an industrial mechanic, and usually ended up working on equipment older than I am.)

taking a stab at it, i think i remember reading mitchell ondemand saying to put a dab or two where the two halves meet on the main cap. but when i did mine, i didnt bother either, just soaked it and installed it. never had an issue
