I've been searching around to try and find a suitable substitute for Hylomar as it is virtually impossible to find locally and I would like to start putting my engine together this weekend so ordering it online would take too long. On top of that its seems that most guys say the new hylomar is crap anyway. I would use crisco but my housings are a little too pitted. I don't feel like taking a chance on swelling my coolant seals with vaseline either.

So I'm considering these products as they appear to be good substitues and they are available locally and fairly cheap.

-Permatex #2 Form-a-gasket

-Permatex Aviation Form-a-gasket


I also found these in my dads garage and was wondering if they are any good...

-Permatex High Tack

- Loctite 515 red

Any input is appreaciated, thanks.

 

the coolant seal grooves on the irons?

 

Actually its my housings that are pitted but its right where the coolant seals touch the housing. The grooves on the irons aren't perfect but they're not bad.

 

oreilly auto parts has a hylomar product on their sealant aisle, go take a look :]

if your parts are pitted they need to be lapped.

 

I used that with good results. From what I read, it is basically the old-style hylomar before it sucked.

 

Ok first off there is no pitting on iron face or inside the housing, anything that a rotor seal would touch is good.

The only place that has pitting (its not really even be that bad) is on the sides of the housing (not irons) where the coolant rings contact.

I'm not really concerned about the housings and irons. I'd probably be fine just using crisco, but I just want to play it safe and use something that seals as well as holds the rings in place.

 

it's your engine, not mine. i would have them lapped, but i care more about the engines i build.

 

I used this once

It works well, comes with a brush (Really messy)
You can pick up a syringe and dump it in there to apply.

 

You don't lap the rotor housings.

Personally, given the pitting you describe I would go find the Hylomar. My local parts stores sell it. Put the hylomar into a cheap drug-store plastic syringe (no needle... duh) and squirt it into the grooves and onto the o-rings.

 

NAPA in Canada sells it again but they won't be open again until Tuesday.
