Should i put anything on my Apexi headgasket??

[Solow240sx]

Ok guys just got my head back from the machine shop, and i have seen acouple guys on here using copper spray on there headgaskets, i have never used this stuff before on a headgasket i usually just install them dry, anyone have any advice??? Its going on a fully built block, and is a 87mm 1.5mm apexi gasket and i will be using ARP headstuds??

Dry is ok. Just use rvt above/around the oil pump and timing chain area so there are no leaks.

Would u recommend using the copper spray or not??

Just put it on dry with some RTV around the Front Cover area.

Also i use the 87 x 1.5mm gasket on my 86.5mm bore engine. Been holding up excellent.

Thats good to no! Because thats the exact same set-up im going with my bottom end is also .20 over and i was kinda worried about running a 87mm headgasket on the 86.5mm bore, but i was told it will be fine...

Yeah I'de prob put it on dry maybe just rvt like he said to keep it in place

I see i have seen alot of people have been using it, you didn't silicone around the front then did ya??....

I would use copper spray, but im sure you will be ok without it, but thats just what I would do, I have built a few motors and always use copper spray on MHG for peace of mind.

i have put copper spray with all my rebuilds. And i put RTV on the top of front cover (you are supposed to do this regardless). No leaks and its been holding up for over 10k miles.

[david200095367]

yea i still used silicone on the front

Ok guys sounds good, i think im gonna use the copper spray just for alittle extra insurance, So to get everything cleared up i should spray it on both sides of the gasket, and before i install it i should run a bead of silicone around the timing chain areas..
