Cam Cover Studs

[danielt]

Does anyone know if the cam cover studs are threaded or pressed in? Some gorilla stripped it in a previous life and I am not sure on how to remove it?

Daniel,

I assume you are referring to studs for the valve covers, but if you aren't, you need to be more specific.

They are standard threaded M8 studs.

No, I wrote it incorrectly. I am talking about the chain covers on the front of the engine. On the passenger side, the nut closest to the crank pulley is stripped and cannot be removed. Any advice you have on getting the nut/stud out is appreciated.

Thanks,

Daniel,

OK, those are standard M6 threaded studs, and, unfortunately, I believe you will have to have that cover off to remove the stud, which means the muffler, too. I believe Vise-Grip pliers will be required, as I don't think there is room for a stud puller. Heat the stud with a propane or MAPP gas torch, as red Loctite has been used to seal/lock that stud in place and it has to be heated to approx. 375° F in order to soften. You can make a replacement stuid by cutting off the head of a fully-threaded standard grade 8.8 bolt and dressing with a file. Use red heavy-duty Loctite to lock the replacement stud.

Thanks Warren, the muffler is not a problem as the engine is on a stand waiting on a rebuild. The only nut left ( besides the guy holding the wrench) is the one on this stud. The stud is stripped under the nut so it won't come off. Most nut cutters are too big because of the ridge around the cover. I thought about a dremel with a cutting wheel and try to split the nut. Any other ideas?

Thanks,
Daniel

hold the nut with vicegrips and drill the stud out of the nut, shd work,and you can remove the remains after the housing is off.

Thanks Warren for the tips. I cut the nut off with a dremel and heated the stud. It came out very easy.

Thanks again,
Daniel
