Since Hylomar is no long available, I was wondering what you guys were using instead? I read RotaryResurrection's rebuild write-up, and he said people were using stuff like Crisco? Really? I just want to put my engine together and I don't know what to use. I don't really want to order hylomar, so I'm trying to find a suitable substitute.

 

crisco works great.

 

Permatex Form A Gasket Sealant No. 2

You can find it at NAPA and the such. Runs a few dollars a tube. I think it works better than the last tube of Hylomar I used (new formula). Dont be suprised when you see it out of the tube though. Its a really dark brown, almost black. it seemed easy enough to use though.

 

Yeah I believe atkins sells it or mazdatrix.

You just have to know where to look. But I agree crisco is good.

 

So that's 2 for Crisco.

 

last I knew Pineapple Racing was using Crisco for there engines.

Others just use Petroleum Jelly to hold the seals in place

 

I heard Atkins uses Petroleum Jelly for the oil seals that is.

 

The thing about petroleum jelly, like vaseline, is that the seals themselves seem to expand a little over night, or so I've read. I'd need a little more than than a day to drop it in, I do have other things I need to do you know. Well, looks like I'll use Crisco, if no one else has anything else or bad to say about it.

 

i use vaseline. has always worked fine for me. i dont really know why crisco wouldnt work either.

 

How long did your engine sit before you dropped it into your car?

 

I'm rebuilding a motor now, too, and I'm wondering the same things. I may have to let the motor sit for a couple weeks before I can swap it in.

 

Any help from the guru's?

 

And crisco will do the exact same thing. Use the new hylomar.

The coolant wouldn't wash off pet jelly or crisco even if you put it in that day. The seals expand and change regardless.

Kitchen products stay in the kitchen. I don't know who comes up with these ideas...

 

There will be many, many different responses based on who is giving them.

I have a good stock of Hylomar, so that's what I still use.

The stuff is only used to hold the seals in place during build, so there are a number of options.

Vaseline has been used for years without issues. I've used it myself when Hylomar was not available and seen no issues

A dab of gasket sealer/silicone/RTV will also do the job as long as it's "sensor safe" (won't corrode the rubber).

 

I found a list of their different gasket makers here: http://www.neverseezproducts.com/gasketseal.htm
So from looking at it, wouldn't you want the #3 or Super 300 form-a-gaskets? Those are both antifreeze resistant, or are you wanting it to wash away with the antifreeze?

 

Well, hylomar only washes away with a solvent. The other thing I like about it is a temp range up to 600 deg F.

 

I had my engine rebuilt by Kevin and it sat in my garage for about 7 months before I put it in the car, and it was in the car for about 2 months before I fired it up. It works perfectly fine. I believe he used petroleum jelly on mine. I didn't smell bacon when I started it, so I still hold that it was the jelly.

 

I just picked up some Form-a-gasket #2 and it says on the package that it is resistant to glycol, so I guess that answers my question.

 

It doesn't make a difference how long it sits, since coolant won't wash off the jelly regardless. My concern with petroleum jelly on the seals is with their longevity after they have been altered by the exposure to petroleum.

It is not a question of whether it causes them to swell or not. This is a known fact. The question is whether that change affects their durability.

 

^Same here. I just want to get my facts straight

 

I've had no problems with Petroleum Jelly, but then again, 3-4 engine builds is not a lot to go by...but I do use quite a bit to make sure the seals stay in place.
