Evening fellas,

So recently I had a shop (undisclosed) repair some stuff on my car but ive noticed apon changing the rocker cover gasket the 6 main bolts that hold the rocker cover are just spinning, last night I tried to tap a thread M7x0.75, (rocker cover leaking oil) because of this

Went to a bolts and bearing shop found a M7x1.00 tapped that because it was the only thing that would work. I got new bold ect my last resort is going to be to use a heli-coil has anyone used this method before also, how far can u stretch the factory bolt holes, ive gone to 1.00 now I dont want to push it anymore then that cheers.

Find out from the shop what happened. That's not acceptable for them to give it back to you and not explain it, at the very least. I'd be getting them to fix it.

Easily done if the monkey... I mean mechanic uses a rattle gun and is trigger happy 

 

rocker cover bolts go into cam caps, it is possible to pull the caps and re drill/tap them to suit a new bolt 

 

could even get new or second hand caps that aren’t stripped out and go again on it 

 

pretty easy to rectify buddy

All 6 of them are stripped mate. I was however able to tap them out from m6. To a M7x1.00 purchased bolts to fit that and washers to prevent oil leaks.. im hoping I can fit them tomorow.

Yep seems the rattle gunnned the hell out of them

 

Ive been told I can just unbolt the cam caps without removing chain and camgears, and just replace the caps with the holes in them? Can you guys confirm this cheers.
