I've just put new o-ring seals in the rotor housings. The whole casing is back together now and the lower intake manifold is in place. When I turn the engine, I can look though the exhaust port with a flashlight and see the HYLOMAR blue gasket dressing on the apex seals. It is worst on the rear rotor. My question is after a get in through the exhaust port and clean off as much of the stuff as possible, will the remaining HYLOMAR burn off? Will my corner seals be damaged or stuck in place?

as long as you can start it it should burn right off

weird, did you clean the hylomar off the housings before installing the O rings using a razor blade?

I doubt it wil hurt things, probably is going to burn up right away... but I'm curious how you managed to get the hylomar in the engine like that?

I had the engine all the way apart just like it is shown in your pics. I just didn't know to clean it off like that.

oops, I hope it doesnt cause any problems. Good luck to ya.

What the hell is the purpose of hylomar anyways.. I used it on my rebuild, but what does it actually do? does it help seal or just keeps the orings and seals in place.?

i use vaseline, no worries it holds the seals in place



mike

So hylomar just does the same **** as the vaseline right.. **** that next time I won't use it then.. I can save a few bux.. I felt so perverted using vaseline on my engine, and liking it..

Hylomar also aids in preventing the o-rings from sticking

i know, its wierd



mike

I felt so dirty that night..

were your apex seals goopy too afterwards? just not with hylomar? https://www.nopistons.com/forums/pub...#>/biggrin.png

no rubbing vaseline on things just feels wrong



mike

It was goopy all over the place, I was so damn excited.. I could have sworn the house wasn't white on that side before I built that engine..

I like rubbing stuff with vasoline. It makes me tingling all over..oops this isn't the rubber-romper-room is it?

Yea I wouldn't worry about it. After I put my engine together I could see some hylomar on the Apex seals and rotor. Some of the hylomar squished out after assembley and after turning the engine a few times it picked it up. The engine started right up though and I now have around 5000 miles on it :bigthumg:
