Well i'm just contemplating my upcoming SOHC setup,

one of the parts I plan on doing to squeeze as much power out of it
as I can, for a small ammount of bread, is a thinner headgasket,
i'm hoping that, that, combined with a nice cam(which should enjoy the higher comp) will produce nice results.

Now I know the thinner gasket can only do so much so I want to go as thin as possible, like a y8 trimmed down to 1layer.

SO i'm a bit worried about the gasket not holding up,
what could happen if it blows, aside from having to swap in a new one?

thanks

 

a blown head gasket can leak coolant into your crankcase. when that **** gets on the bearings. it doesnt allow them to stay lubricated. so they get screwed up.

 

Can warp the head surface and the block surface, creating future leaks. Honestly, avoiding a blown HG is the best option. Having to put a new one is would be the least possible damage caused.

 

Mill the head and run a 2 layer, dont **** around with a 1 layer headgasket

good call


What damage can blowing your headgasket do?
well you head gasket would be fucked up

 

overheat the head and cause major leaks

 

i've heard both good and bad about cometic gaskets. +0.3 in cr won't even do too much for you.
i maintain that if you want to bump compression, do so with pistons.
could you be more specific about your engine please?

 

well i'm thinking a jdm d15b vtec

dont even have the thing tho! still got my cx haha,
soon tho

but yeah you're probably right,
which is why I asked first of course.

I dont want to mill the head though, because I might go turbo later on

maybe i'll just try'n keep it simple,
stay low comp, throw a cam, boltons ,and leave it at that. should still be pretty fun.
I'm definetely down for the sohc feel.
