head gasket sealant

[Ryan Family 510]

I have read several topics on this....maybe 25-30...some folks say use sealant on the head gasket others say NO! I have an L20b straight out of the machine shop, head and block resurfaced. Would like to know thoughts on this.

 

Thanks

Shouldn't be needed with a fresh head and block.

Spray on copper coat. Cheap insurance against small seeping water/oil leaks. Also make next hg change little easzier(gasket doesnt stick so bad) ive done 3-4 hg's with it and no isuues. But lots of us say dont need it and everything is perfect,yes its not needed.

No.

Sealant should -never- be necessary on any Datsun, provided the sealing surfaces are flat, and clear of any leftover material.

See what i mean. Personally i hate doin shit twice. If its your first time doin this,$6-9.00 is worth not havin to worry bout it

If your using a fel pro gasket you don't need sealant. You only need sealant if your using a copper gasket or your scabbin together shit not resurfacing anything.

Yes and no.

 

If you use a factory head gasket, which I only do and I highly recommend, then you don't need to use any copper coat.

 

If you use a cheap aftermarket gasket, then yes, use copper coat.

 

There is a distinction though. A factory gasket is graphite coated, some aftermarket (most I suspect) are not coated. Use the copper coat on non-graphite coated gaskets.

not sure if this helps.

this is the head gasket and the company I got it from.

 

 

 

 

Change any opinions?

If you don't trust your own work then go ahead you'll feel better. I caution the use of sealers as some numb nuts will slather RTV on with a butter knife 'cause they see chevy owners doing it. If a little works, then more will work better.

 

Nissan put the fresh heads and blocks together without it. You have a fresh head and block so.....

my gut says don't use it.  I'm a virgin and want to make a good first impression!!!!  You know that kind of pressure!  

 

So I am going without extra protection on this one.

 

If you are still interested in adding advice, feel free to go to my project page (The new guy).  Have a cam sprocket timing question.

 

Again, the virgin just wants to be confident.  So far so good.  I'm reading and reading and reading and I don't think I qualify as a chevy guy.  So I should be good.

 

P.S. we just finished Breaking Bad.  I get it!

This gasket already has a silicon seal (blue line)

[Ryan Family 510]

That's what I figured.
