question, and i know this sounds like one of those stupid "my buddy did (insert something stupid) what should he do? when its really you that did it. but trust me its not.

anyway, heres the deal, my buddy built an engine for another buddy of mine. the buddy who owns the engine told me today that the builder put hylomar on the side seals and apex seals to hold them in place when assembling the motor.

how fucked is he? i told him that that stuff is only to be used on water seals because it gets hard.

is that stuff gonna break all his seals when he tries to turn/start the motor?

will it just burn off?

will it burn off and leave some kind of residue thats gonna cause a problem later?

or can he just start the car and everything will be ok?

i dont know anybody who has done this before, so i dont really know what to tell him.

thanks for any help

 

I thought hylomar stays sticky/gooey and doesnt harden up... I swear thats what the tube syas. As far as it being in the motor, I dont know. Maybe dump some sort of solvent in there to kind of dissolve it and then pour MMO or some other oil and crank it by hand to get relubed??? I guess I'm not helping sorry.

 

doh take it apart and restack it your odds are aginst you, severely

 

Is the motor already in the car? If so, I wouldnt worry about it too much. It might have some trouble starting, but itll burn off. Hylomar is a non (or cemi) setting sealant. Meaning it never really becomes solid. Im sure it cant be good for compression, but it wont stay in there too long.

 

Uh, that's FUCKED.
I would disassemble it an remove all that Hylomar as much as possible.
Oil / gas does not normally flow into those spaces very frequently, and I think you'd end up with broken pieces more likely...

You're definitely screwed. I used too much Hylomar around the water seals on my last rebuild. I ended up breaking an apex seal so I had to rebuild the motor. The excess Hylomar was still around the perimeter of the irons, gumming things up, and possibly assisting in breaking the apex seal. The stuff is evil! It won't seal against any pressure, and it won't disappear either. I won't be using it again.
