Trying to helicoil the head with it still on was foolish at best... BUT, a few small twists of aluminum aren't going to cause a loud knock... it'll shred the cylinder wall and chew up valves. A loud knock or pop could be the result of a sticking valve or a leak around one of the spark plugs where the helicoil didn't seal well or is leaking.

Exactly how bad is the noise?

If some shrapnel did score the cylinder wall you're going to have to pull the engine.

Do you have something against platinum spark plugs?

What make and model plugs did you install?

Pulling the engine with the transmission attached is a little more difficult, but I (and many others) think it's easier than trying to line the engine and transmission up when reinstalling if you separated them.

Right now, I would pull the plugs back out and inspect the helicoils; Then I'd check the spark plugs for damage or cracked insulators; Then check the spark plug wires.

Sorry, you're having such a terrible time with it... mine was a horrible hell when I got it. I bought mine for $300... well, my friend bought it from a used car dealership for $300... that's what the scrap yard was going to pay them. Yup, they were going to scrap it... he probably should have let them. I have more money than I want to think about sunk into this car now and I'm sure I couldn't sell it for more than $5000.

thats what i said?a small puieace of aluminum couldnt develope a noise such as this.. and Its is a deepish very loud tick, i sprayed around the plugs with soapy water and no leak as the car ran, i pulled the plugs to see any damage, none. as far as the heli coils they looked ehh okay.

what is the chance of a valve sticking as soon as i change my plugs and i started the car 3 hours prior with no knock, take out the autolite platnums 5503's and put in cheapo oem champions. ( just temperary) ?? i doubt it...

when i stated the car the miss was pretty much gone (YAY!) then the second it started came a loud knock deffinitly from the top of the head.(damnnnn)

The heli coils are steel, and a good chunk could have broken off.. im gonna find out tomarrow..

ill run it one last time, becuase god damn it my supra wasnt some pieace. its damn near flawless and i worked my ass off for it.

and now, literlly now all my new parts such as huge front mount, profec ii boost controler and all kinds of shit are coming in the mail and well now i gotta pull my head?

God damn it! im so sick of this man, i cant thank you guys enough but shit this is geting old.
