1150 Cam Cap Threads?

[Nessism]

For valve cover attachment.

Are these threads really 7mm or am I having a brain fart? Stink'n 7mm helicoils are hard to find.

Ed, they are 7mm x 1.0. You can get the kits from Napa or you can borrow mine if you dont have enough need to justify buying one. Ray.

I install them in my drill press to ensure they are going in straight. You can even do them at my house if you want. How many do you have to do? Ray.

[Nessism]

NAPA is a good suggestion Ray. Didn't think about them. Going to check them out. Just a little odd to see 7mm threads.

Thanks for the offer but I'm too lazy to drive across town. I have a drill press and remember you recommending the use there of in previous threads on this subject. Thanks for that too.

[rapidray]

No problem Ed, glad to help. Ray.

do all the caps and be done...they will fail sooner or later.
they tighten against a shoulder and when the rubber biscuit gets hard and quits sealing people tight the bolt but...all this does is pull the threads out

[dorkburger]

Yes, I stripped one exactly in that way...It stripped really easy. and I'm a weakling

Fixed the threads tonight. Ray was spot on about using the drill press. Had a little trouble getting the helicoil to start until I chamfered the lead-in thread. At any rate, one less project that needs doing.
