Just bought a d16z6, it came with a clutch. I took it off and found out 3 bolts to the flywheel on the crank are stripped out. I'm kind of stuck on what to do, because i have a brand new clutch to put on, and i would hate to lose the whole motor because of the strip.

Just looking for some opinions and suggestions, i was thinking about bringing it to a machine shop to see if they can drill it out and re-do it.

I was also thinking about buying a new crank, but budget wise it might take a bit.

Thanks fellas~

Kind of an old thread, but i had to take care of some personal business before i jumped back onto fixing the motor.

Either way, i'm back with the same problem. Any more suggestions? Anyone have a z6 crank for sale? or knows where i can get one? Thanks a lot!

they are the same, why not drill them all out and re-tap them all to the same size? Then i would think that you wouldnt need to re-balance it. Just an idea...

I've been looking up different ideas on how to fix this. The motor is going to be built for turbo sooner or later, and i was reading if you're just a hair off while drilling them, the flywheel will be off balance.

but do you think drilling and re-tapping would be reliable enough for turbo? definitely shoot me your opinion. the more the better!

That's what i was thinking. I've been looking around, i found a fella on here selling a d16a6 crank. Do you or anyone know if it will fit in the z6? is there any difference or are they the same?

I don't want to run into any problems down the line.

how far down are they stripped?

i knew this one guy *cough* who accidentally used automatic transmission flex plate bolts instead of manual transmission flywheel bolts (longer). Well those bolts pulled out. But he retapped the threads and used the right bolts and his flywheel is still running strong to 8k to this day...

it will fit.
Awesome, thanks for the info, is there any performance difference?

I'm not to sure, i will try to find out, maybe even take a picture. Keep the opinions coming, they're a lot of help!

i'm pretty sure the only difference is that the z6 crank has 4 oiling holes per journal and the a6 has two (like a y7/y8 crank)

Stripped as in the heads are rounded? Weld a nut to the top of the bolt and get them out.

if this is the case and you don't have a welder, what i did when this happened was get some weird sized 12 point standard sockets. it was something like 15/32 or 23/64 or something odd like that and just hammered it onto the head of the bolt and got it off with an impact gun.

but if its the threads inside the crank that are stripped, then make a boat anchor or a mailbox pedestal out of it.

The threads are stripped inside and the bolts are. I think i am just going to get a new crank shaft. I've been talking to someone about a d16a6 crank. The only thing he said the difference is:

"The snout is the side that the crankshaft pulley is on. So you will need an 91 CRX SI d16a6 pulley."

Is this right?

Thanks again for all the replys.

i don't know, but i'm sure someone will answer that for you. i'm aware that some cranks have different snout sizes, but i could never keep straight which was which.
