Engine failure

[Keeffa]

So update! Car has been running good, just installed a new clutch so i had to baby it for a while. I ordered ARP studs and put them in with a new head gasket, NGK spark plugs, MMR cooling mod since the block is already out again, radium coolant reservoir, and PP1 radiator.

I also got the heads and block checked, all was good. But weird thing is, is that the car sounds a little deeper now for some reason, I’m not sure if the mufflers were damaged from the coolant and oil mixture in the exhaust gases but it’s kinda throwing me off. Sounds more throaty on pulls, compression is good and no leaks, no check engine light so I’m kinda wondering why it sounds different. So far i emailed APEX Torque and no reply sadly, i might make a call because it kinda ridiculous that i spent money on these headstuds and they failed.

Just wondering if it's been recommended to retourqe the heads after a running in period.

ARP Headstuds shouldn’t have to be retorqued on coyotes since it is such a pain in the ass to do them, especially since the torque rating is so high in the end it’s most like you don’t need too.

Yeah that's good. I'm kinda old school I guess. I'd imagine head gaskets are made to not need it now.
Can you tell me what is the final torque setting.

They haven’t emailed me back. Smh

When the phone don't ring you'll know its them.

It’s because of MLS head gasket design. No re-torquing needed.

On my gen 3 you would not be able to tighten or recheck the rear headstuds without removing the cams. I bought the arp ones for my build because I've used them multiple times with zero issues.
