Found My WOT Exhaust Leak: Why?

He is full of crap. There is nothing wrong with the mitsu mls.

Exact same problem I had on my evo8, I'd rather buy new OEM head bolts than re-use arps. New ARPs or get some L19's.

Why?

Perma-Torque?


It seems that perma-torque's are the type of headgasket that you do once, then forget about. That's the route I went. Although, my car hasn't run yet with it, many other seem to have great success with them. I have never heard one person say they are junk, while I have heard handfuls of people say that about the mitsu MLS. Again, this is just what I have heard.

I say OEM Mitsu headgasket, good new head studs and call it good.

Also, I'd take your head it and have it check for flatness, and possibly get a straight edge to check your block's flatness too.

Yup. Head studs shouldn't be reused, period.

A1's or L19's + Permatorque = done. It's been proven over and over. :D

I know about the greatness of MLS gaskets. I have used the Mitsu MLS before. The perma-torque is great, I know.

I already checked the block for flatness, it appears to have a .002" variance which should be within spec.

ARP does not manufacture 6-bolt L19s anymore.

A1/Map and a Mitsu or Fel-Pro MLS.

Then Bye Bye car! :)

[Kracka]

Why not save the funds and get a new set of regular ARP's?

[Shane@DBPerformance]

Has it been knock a lot and blew it? You might want to make sure the head and block are perfectly flat, or else it might keep blowing in that spot.

[sleepydsm]

The first time it blew, was timing belt side of cylinder number 1. Then I slaped another one on, and it kinda failed in the same spot lol. So I had the head resurfaced, and I then It failed in the middle of cylinder number two.

Thanks MAP.

Permatorque and MAP studs at my doorstep when I get home from work (thanks to bribing a friend to pick it up for me).
