One of these days I'll search all the M156 forums for head bolt failure threads but this one just came to my attention tonight.

not sure what the importance this is? I feel like everyday i see a new headbolt thread. Might as well post up everytime you run over a kamakaze squirrel.

For this reason alone, I bought the Easycare extended powertrain warranty for $3k

LOL, I have a suggestion for you. When you see a thread title that doesn't interest you, DON'T CLICK ON THE F'ING THREAD!! Could it be any simpler?

Merc63

Should have just saved your 3k and put weistec arp studs in and be done with it.

tc1728

are you talking about these?

Indeed

Sincity

You think??? LOL!

Better yet forget the Weistec studs, in which you have to pull the heads, just replace one bolt at a time with the new OE bolts.

roadtalontsi

theres a sticky at the top about headbolts. headgaskets shouldnt be an issue if you replace the head bolts the correct way. Non of this one at a time crap guys its an amg not some kia/honda rice crap.

Merc63

Yoooo mr Renntech that's not true. Check out my build thread for the stage 3. You can do the studs one by one with the head on..

Why would you use those junk TTY bolts, when you can use ARP 625s, which I believe are there strongest studs available.

Merc63

A head gasket is a head gasket, doesn't matter if it's my lawn mower a Kia or an amg. Nothing wrong with switching studs one at a time, if you know what your doing.

Did you switch them with the engine still in the car, or did you pull it out, I forget and am too lazy to find the build thread.

Merc63

Engine in car.

Remove valve covers and cams and they are right there.

Jasonoff

Snap a head off, dump some coolant, call dealer.

DONE...

Merc63

Or just put studs in for a couple K and have a bullet proof seal.

Jasonoff

That's way more effort and money out of pocket though

jvanbrecht

That is also illegal. My warranty expires in a few days anyways.
