Going up a hill in 5th at WOT.

Completely stock engine lol.

This is why you dont do wide open rippers in 5th when you have FI.

 

nicely done, on burning the valve.

 

how hard was it to change the valve?

 

DANG!!! thats one dead valve...

Put it away!!!!

It is too much load for the engine. The EGT's go through the roof and stuff starts melting from the detonation.

 

I have had the same thing happen. wasnt cause i was going up hill though.

I was N/A at the time. so????

yep. although i think mine was either from an injector leaning out (less likely) or the machine shop thinks that a piece of carbon just got stuck in the valve seat and burnt through like a torch. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Liquidgsr &raquo;</TD></TR><TR><TD CLASS="quote">how hard was it to change the valve?</TD></TR></TABLE>

Easy "Hey machine shop, will you fix my head for me"

"yes sir, that'll be 234 dollars for 2 new valves and a resurface"

Damn thing came back like brand new

 

hmm i want to change my vavles, but i can't resurface the head myself. Im thinking of change my valves and springs.

I honestly think its worth the money to just have the damn machine shop take care of it.

 

i did. detonated on nitrous. looked similar to yours except the damage was extended to most all the valves

 

daaamn that was all the damage?

 

Other than replacing the valves, did you do all the other work? ie: Removing the head, etc

I am 99% sure I burnt a valve from the exact same reason at VIR for ITR Expo.

Pulled the head, replaced some hoses, dropped head off at machine shop for milling and valve replacement (they automatically re-grind every valve and seat and replace all the stem seals while they're in there). Had 2 valves replaced. Cost me all in all (including head set gasket kit) like ~400 bucks cause I bought some tools along the way.

 

Are there any step-by-step guides you would recommend for taking off the head? I have the Haynes manual, and I've looked through a few team-integra articles.. but I'm curious as to what made it easiest for you.

Messing with the timing belt is my biggest fear right now, although there are plenty of guides for that step.

Edit: Right now I'm working with a full set of 16 brand new valves, 16 seals, a new head gasket, and some of those cotter pins. I have a machine shop lined up to do the work once everything is ready. Any other expenses I should expect?
