Searched but came up with nothing.
Has anyone here been in a situation where 35+psi pulled the threads right out of the block?

 

I've seen it on single cam once that ran high 20s on base map. It most likely happened thanks to some slight detonation. Helocoil and retune it.

 

hmmm id be a little weary about using heli coil for headstuds. You might have had too much timing creating massive cylinder pressure, but it would take alot.

 

i wouldn't run heli coils, i have put 45 pounds of boost with head studs using timeserts.
i would never heli coil a block after using timeserts

 

Timesert are great.

 

Timeserts are great.

 

yea timecerts are much better I just wasn't sure that you could use them on the block because they are flarred in the end. i guess go with timecert.

 

you could always have them machined and use some 1/2" ARP's

 

Timeserts FTW. I am a technition a GM Garage. Cadillac Northstar engines between the year of 97-01 had a problem with the threads pulling out on the back head between 3/5 cylinder. We always drill the tread out and timesert it. We always go the extra step and do every thread. Because that engine is commonly known to pull threads. Considering its the same aspect, Honda/Cadillac both use Alum. blocks, I would Timesert it.

 

timecerts?

I know there are proven methods that work and I have read numourous threads on here so please I am just trying to learn a thing here

I take it most of you running these are making 600+whp/running more than 35psi?In the image below,the user installed ARP head studs right into the block but I did not find any content in his threads that stated he used a helicoil to keep the studs in check or another method...

Better than any helicoil setup.

 

Timeserts are much better than helicoil.

Is this what everyone is using?
Has there been cases of people pulling threads out the blocks?

 

bought a timesert kit two years ago to fix a d-series block that had two stripped head stud holes after bad overheat. after repair, was able to torque to oem specs and motor is still running with over 200k on it.

if you need a d-series kit, i still have it, you just have to order the timeserts themselves. they're like a dollar.

It happens due to incorrect install or overheating the block.

 

TIMESERTS FTW.
I broke down a while back and bought the complete Honda/Acura timesert kit which was not cheap $350.00 approximately. I have fixed numerous blocks using the kit and have not had 1 come back with any problems. I even had one customer with an LS block that was Helicoiled in all 10 holes. I pulled the coils out and installed a full set of timeserts and the car has been running for over a year now. The kit paid for itself after using it only 6 times. The best money I have ever spent IMO.

 

Timeserts

FWIW, having a 1/2" headstud setup isn't going to save any money or help out longevity wise lol Plus if you need a spare head in a jiffy, it's not going to happen!

no, these people are only using them cuz they [freak]ed the threads in the block up. i can't imagine all the threads being pulled out by high cylinder pressure produced by our motors.

 

correct me if I am wrong but I don't think any of your stud holes are stripped. Your just wanting to install timeserts or helicoil because your worried that boosting 35+ psi will strip them.. not gonna happen...

 

bottom line is that steel threads are going to be a lot more stronger than aluminum threads.

 

wow i have never seen that **** before!

do you see the flaw in this statement?

heres a hint: the inserts are still in aluminum so its still gonna have a weak link.

 

At one point I wanted to put timeserts on my whole engine.

The bolt goes in much nicer into a time sert than aluminum block

 

as said in almost every post here, timeserts &gt; *.*



used them in a non honda application and they were great and still holding up from what i understand (dont have the car anymore).

 

A timecerted hole, if properly done is stonger than a stock alum threaded hole. Normally more threads per inch in metal is stonger but alum is so soft that courser threads are stonger, very similar to wood.
