Hi I recently had some loud clicking noise in my car about a month after oveheating. I removed the rocker covers and I noticed that one of the rocker arms had sheared the threads in the aluminum head and was sitting in the rocker cover when I removed it.

I was wondering if it can be repaired with a heli-coil. Does anyone have any thoughts or experience with heli-coils. I was on the heli-coil site and they say it can be used for the head bolts so I was thinking taht it can be used for the rocker cover bolts as well.

Any help would be greatly appreciated

Helo coils were a great innovation in my opinion... Since its for just repairing a rocker "cover" bolt (valve cover) I dont see it being a problem!

 

It's not the rocker cover bolt that broke it's the actual rocker bolt itself that sheared the threads in the head. I know that I need to replace the rocker bolt because the are torqued to the yeild point.

 

That maybe a whole nother issue then.. Since its the rocker arm stud...

Its worth a try vs a New head!
Good Luck hope it works out for you!
Keep us informed.

 

Thanks for the tips I'll let you know how I make out

 

You can get reusable rocker bolts
