blew headgasket (vid inside)
well went to tune on the dyno yesterday. numbers seem kinda shitty ...made 334whp and 242 ft lbs torque at 20 psi on a T3/t04e ... 2.5" exhaust.... but on the last run the headgasket blew at 7800 rpms and one of the coolant hoses burst as a result of the headgasket. anywho, the strange part was that right when this happened, the passenger side wheel stopped dead and the roller under the wheel was still rolling which kinda ate up my tire in a flat spot as it rolled against the tire. thats just the strange part which we dont understand. spark plugs were fine but 1st one was wet because of the coolant in the cylinders. anyone have any input as what may have caused it? head lifting? the car still turns over ns hit...had arp head studs and were torqued to 100ft lbs. was thinking to get a new oem headgasket and torque to 110? heres the vid:

Re: blew headgasket (B18 CYA)
I don't have an answer to your post, but why are you torquing the head studs to 100ft/lb? At that much torque you probably pull the threads out on that cylinder.

yup! 100 ft lbs??!?? DAMN
your hose burst because the boost escaped thru the headgasket and went into the coolant.
get a honda oem hg and use lots of copper spray on it and torque the arp's to 60-65 ft lbs. in a 2 step fashion.

that is to high , read the pink paper that comes with the studs , 70ftlbs with molly lube and 85ftlbs with 30w oil , you can warp the head if you torque them to much ,

God Damn that **** was violent!!
Did you replace the head gasket at the time when you did the arp studs?
You should only have torqued the head to 80ftlb with arp moly to begin with, did you have a boost spike at all when the gasket let go?

Re: (Adi Raaa)
the last time i saw a hg blow on the dyno was cause the sleeves cracked 
but anyway if i was you i would buy a new gasket get the head checked for warpage and torque the studs correctly

Use a precision straight edge and some feeler gauges to check for warpage. A helms manual will tell you how.

I can tell you they are stretched. Call ARP too and tell them what you torqued them at...
