Cars in general. Has anyone had issues with cometic mls head gasket at 30psi of boost with 12mm arp head studs with standard arp washers? Is it past what it van handle?

Wish my car was powerful enough to have such problems. Twice the boost I am tuned for!!

Lol I guess.

Top of the gasket with some funny marks.

Between the gasket shows some blowby

Head which looks like the studs have pulled into the head. Can catch the lip with my nail.

Dunno what to do now

Not run a MLS and use bigger lazer cut washers is a good start .....

U seen what I said

Have a think, your on E85 aren't u ?

E70, last time I was chatting with my tuner he runs them at 0.8 lamda and knows I am on e70.

If your referring to my dyno sheet that shows the graph leaning out on target boost I've never driven it on that setting through the boost controller.

Lifting heads and E85 has been around for years

Have a think what u could change to suit

It all begins with the fuel
