Can I use just straight vasoline to hold the water jacket seals in place? or do I need to use Hylomar.....I have been using this stuff called Curil-T, same as Hylomar, a non-hardening sealant.



I need to build a motor on Saturday and the Curil-T is on backorder :(



Will I be able to do it?



Thanks

Yes, but vasoline makes the seals swell. Hylomar does not.



Why not just splurge the extra $5 for a tube of hylomar at lordco or Canadian tire? It works much better for holding the seals in place, and $5 now is certainly a lot better than dealing with the headaches of seals popping out.

what i found out this summer is hylomar turns really thin above 100 degrees...it doesn't do a very good job of holding the seals in at that temp, so i've reverted back to putting motors together in the middle of the night--when it's much cooler out.



i'd say throw the tube in the fridge for an hour before you start, but it would probably warm up too quick.

I use cheap wheel bearing grease. Never a problem since 1980.

I've never had a problem using vasoline.

I think the majority uses vaseline but I could be wrong.

i tried it once, but same story as the hylomar with the heat. i've got some lucas red n tacky...maybe i'll give that a go for next time... but it's no big deal. i don't sleep anyway, so might as well do something productive with my time https://www.nopistons.com/forums/pub...DIR

I used regular wheel bearing grease to assemble the motor this weekend and it seemed to work pretty good! I"ll probably use it from now on!

it sounds like there's lots of options that all probably work.



i use RTV clear (not the hi temp stuff) Permatex silicone adhesive for just about everything. i used it on my waterseals, as well as my LIM/UIM, throttle body and oilpan and run no gaskets on these assemblies.



i coat both mating surfaces thinly and let it set for approx 30 minutes before joining the parts. i coated the entire waterseal goove sparingly and it isn't going anywhere. it does need 24 hours to fully set.



no leaks. no sweat. inexpensive and easy to find.

all i use is vaseline,ive never had a problem. and in P.R 99% of the engine builders use vaseline also.
