Ryan Family 510 Posted September 30, 2014 Report Share Posted September 30, 2014 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 Quote Link to comment
]2eDeYe Posted September 30, 2014 Report Share Posted September 30, 2014 Shouldn't be needed with a fresh head and block. Quote Link to comment
kelowg Posted September 30, 2014 Report Share Posted September 30, 2014 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.

metalmonkey47 Posted September 30, 2014 Report Share Posted September 30, 2014 Sealant should -never- be necessary on any Datsun, provided the sealing surfaces are flat, and clear of any leftover material. Quote Link to comment
kelowg Posted September 30, 2014 Report Share Posted September 30, 2014 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 Quote Link to comment
scooter Posted October 1, 2014 Report Share Posted October 1, 2014 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. Quote Link to comment
Stoffregen Motorsports Posted October 1, 2014 Report Share Posted October 1, 2014 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. 1 Quote Link to comment
Ryan Family 510 Posted October 1, 2014 Author Report Share Posted October 1, 2014 not sure if this helps. this is the head gasket and the company I got it from. Change any opinions? Quote Link to comment
datzenmike Posted October 1, 2014 Report Share Posted October 1, 2014 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..... Quote Link to comment
Ryan Family 510 Posted October 1, 2014 Author Report Share Posted October 1, 2014 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! Quote Link to comment
]2eDeYe Posted October 1, 2014 Report Share Posted October 1, 2014 not sure if this helps. this is the head gasket and the company I got it from. Change any opinions? This gasket already has a silicon seal (blue line) Quote Link to comment
Ryan Family 510 Posted October 1, 2014 Author Report Share Posted October 1, 2014 That's what I figured. Thanks Quote Link to comment
