Cam cover stripped threads
Hi all,
I decided to change the cam cover gasket on my ZR 1.8 k series and my torque wrench played silly buggers on me and nearly stripped a few threads. I could feel it wasn't right so stopped, but I think it's too late. What are my options ? Thanks Pete. |

Helicoil would fix it

I know it's a bit late for you, but for others, cam covers and the like don't get touched by my torque wrench. I would use the general centre out crisscross pattern and a 3/8 drive ratchet. Using one hand just back of the ratchet head snug up all the bolts to the tightest repeatable "torque" with that one hand. That should be enough on a new gasket. If you're not comfortable with that, go another 1/8th turn tighter. Those things usually have a torque spec of 5-10 ft lbs - often specced in inch lbs.
Helicoils are an excellent solution, though, for you. Before that, though, I would try blowing out the bolt hole with air pressure and running a tap in to clean the threads. If there are still some threads left after that, put the bolt back in with some blue Loktite just snug like I described. Cheers, Glenn

They are still gripping, but they just feel a bit "soft" when tightening by hand. Most of them are nipped up and tight. It's mainly 3 that are in line with the spark plugs / coils.
I used a small torque wrench this time round because I didn't last time, and it was leaking. If it's not leaking then I will leave it until I have to get in there again. Pete. |

Does anyone know the thread size and thread pitch ?
I think M8 for the size, but no idea on the pitch. |
