VERY SAD DAY (destruction pics)....

Well if anyone has been keeping tabs on the twin spark super head i have theres isnt much left to it......

This was after two heat cycles to let the new valves break in and a brand new 88 piston....

Keep in mind this was 3/4th throttle on decel off the rev (NOT WOT) thats why im extremely surprised this happend. (did all proper heat ups) etc.

Only thing i could find that could send my intake valve into the head like it did is the top retainer broke into two i heard a snap/shear and then loose change and marbles in a tin can shacking around. This is where my argument is, this be a faulty part? Could CHP be liable for such a thing? or is this a loosing battle as im the engine builder and its my fault, The ****ty part is i didnt even ride it. Might i note, Not only did i go over the head 3-4 times, but i had a professional check everything just to make sure everything was good and it was.

Anyone think its worth fixing?

id say its worth fixing...

Zachmotox179 · Feb 27, 2009

thats not even fixable is it?

Twister773 · Feb 27, 2009

pretty sure it is...weld and resurface it all, new seats etc etc

Twister773 · Feb 27, 2009

im sure firepower will buy it from you if you dont want to fix it cause i guarantee you he can and will fix it lol

The head is certainly recoverable as long as there aren't any unseen cracks around the valve seats, etc.

No problem. I've fixed much worse. I've seen the broken retainer on Tak's before. It sure the fack AIN'T CHP's fault!

Well what kind of retainers would you recommend to use, instead of the POS takegawa ones?

As someone else on here once said....

"...aw hell, that'll buff right out!..."

Go and have the retainer checked for hardness. If it's over 50 rockwell, Id say it's a faulty part. It looks brittle (too hard) from the pic.

Damn i haven't heard anything like that since shop class, any ways thats a great idea. Sorry about the engine man that sucks, i'd get pissed or cry maybe both.

Give Brady Becker a call at Fast Core Mods in Metamora MI. He unscrews stuff like that all the time.

Anyone know if Tak uses a different angle on the retainer/keeper than Honda?
