Alright so today i was finally putting on my port flow head and i went to torque the headstuds down. I was doing a 3 stage torque made sense to me 25 50 75. This is a a6 z6. Both head and block recently built. I was turquing 3rd bolt to 75 when bam...stripped. I was hoping it just made a noise like they made noise coming out. But i turned a little more and knew it was stripped so i took it out and all the threads are stuck to the arp bolt. What did i do wrong recently i made thread about torquing and they said most people go to 75 ft lbs. Please info would be nice im ready to just quit

 

heli-coil kit. pull the head and by the kit form napa.

 

time-sert

 

Man but why the hell does that happen. I went to the next one after that and it felt like it was about to strip

 

heli coil!?!? lol, YOU DO NOT WANT TO USE HELICOILS.

Hmm i just want to know this...i drained the coolant but there was still in head and block, like when i took off head coolant was coming out too. So some got in the bolt holes. Would The water get trapped in the bolt holes and not being able to compress any more make the stud come back out with taking the threads with it?

 

possible but i would think that the coolant is more likely to go up around the threads than just sit there.

 

yea thats what i was thinking when i was putting on the head. I couldn't see any other way to do it unless i took block off and dumped it upside down to get coolant out of there.

Compressed air and a rag..

If the treads are machined really well, then the coolant would be squished and has nowhere to go. It would give a false torque reading. You'd want to clean out all the oil or coolant on all threads before proceeding to the next step.

 

i use a wet dry vac..

Compressed air, rag, and then a shop vac here.

Did you chase the threads before you started putting the studs in?

I torqued mine to 72ft/lbs (all my TQ wrench would go to) and I was uneasy about putting them on that tight. I tried checking the ARP website awhile back, but it was down for maintenance (2nd hand studs, unused, but unpackaged), so I had to go off of hearsay.

 

definately time sert it. happened to mine also. rs machines chaeged me$40 a hole.

 

Well if anyone is intrested block is for sale cp pistons 9:1 pauter rods benson sleeves acl bearings so on and so on cost me 3400 or so

 

how much?

why dont you just keep it and buy my d16 head bolt hole kit? ill sell it CHEAP compared to what i paid for it.

 

probably like 1500 never seen boost and only 1500 miles thats over half the price i say its a steal

Helicoils are prone to pulling out again because they aren't as strong as the original threads. Time-sert is the way to go. Dont scrap a project b/c of a tiny little setback. Keep on trucking. And, Mike is an honest seller. He'll do you a good deal. Check his vouch thread in his sig.

Naw just dont got any more money to throw into this project or energy, others can benefit from it i dont care ne more

 

Actually helicoils are used in everyday aircraft construction. Every threaded piece of aluminum has a helicoil. They work better than most people give them credit for. We made close to 700 with a block with 5 head bolt helicoils and no head gasket problems to date.

We use time-serts and have never had a problem with them...
