Super Jet Hondabond / Yamabond / 1211 cure time ?

[Pablo]

How long does it take for that stuff to cure? Can u pressure check ur cases immediately after a rebuild?

 

[tor*p*do]

24 hours

 

[Pablo]

24 hrs for both ?'s

24 hrs for both ?'s

I'd say yes if its cured after 24 hours then why not pressure test? Just sayin..:silly:

Call Shane about this...

 

[Pablo]

I was wondering if u needed to wait the full cure time before u test. That's the safest thing to do I imagine.

 

[tor*p*do]

24 hrs for both ?'s

yes

I have never pressure tested a motor and have only blown 46 motors in 11 years...:clown:



Yes I would wait at least 24 hours...

Paul Lehr said it skins over in an hour and could pressure test after that happens. I didn't get to that point tonight but if I had the time I would have tried it. I don't see a problem with testing early, before complete cure, since the stuff is supposed to remain pliable anyway. Mine will have passed the 24 hour mark before I can check it but at least Paul provided some food for thought. Thanks for the input boys.

My experience has been that testing it at less than full cure yielded not so good results, proceed at your own risk on this one

I always wait 24 hours for it to cure on case halves before pressure testing.

I usually only use 1211 on the case halves and then install the rest of my gaskets dry. If say, the intake manifold is leaking then I 1211 the gasket on both sides and retest within a few hours. I have never had a 1211 covered gasket have any problems when pressure testing right after application. However, I always let the case halves cure fully before putting pressure on them.

Anyone ever put it on their base gasket?

We put it on Munki63's base gasket, we couldn't get the base gasket xscream sent us to pass a pressure test without the 1211

i use 1211 AS my base gasket on the 760 cylinders. help to lower the port timing with out milling the bottom of the cylinder. .025 is not alot (thickness of base gasket) but it helps!

 

[Pablo]

U guys think the Hondabond adds enough thickness to the base gasket that it needs to be accounted for?

Not if you do a thin layer of it

 

[smoofers]

Not if you do a thin layer of it

Agreed, even with a thin layer it always seems like most of it squeezes out when you torque.

All the 211 does is fill in the imperfections in the gasket cylinders
