Tension bolts spec
 

Hey Guys,

I while back I read a post about torquing the tension bolt to a higher spec than factory
setting. I believe it was Pettit Racing that did it, I did the search but did come up with anything. I just like to reread the post and see what are the pros and cons. If you guys have any info, please send me the link.

Thanks, Jay

I just did this search a few days ago b/c mine are all leaking. The spec was 85lbs for high performance engines built by a company that had rotory in the name. can't remember what link it was under the search.

There were a few others that torqued to different amounts above the normal 26-30lb range, I loosened all mine in order, and then torqued to 40lb, i haven't finished putting it back together yet or pressure tested so i'm not sure if it fixed it yet.

I would recommend calling Cam and talking to him though...

Kyle, I knew you would chime in with some useful answers. How's your back treating you? Did you get your car running?

I blew my water seals because the stupid plastic radiator fans broke off from the fan motor. The temp spiked and it was all over before I could pull over.

Forgive my ignorance, but what the heck is a "tension bolt?" All bolts are under tension when tightened, right?

Defined as the bolts that clamp ("tension") the engine segments to each other.

Ah, the long bolts that hold it all together. Thanks!

Ohhhh.... Well then it MUST be 85 ft lbs if the company that had rot(a)ry in the name said so. :wallbash: Good luck with that!

not recommended.

your tension bolt o-rings are worn and need replacement. torquing them more will make them more prone to complete failure.

they are $1.45 each at mazdatrix. don't be cheap
