Is it possible to remove stud without removing the head?

 

Yes, rocker studs are bolted on from the top. You should be able to use a deep socket to remove.

 

Stock rocker studs aren't "bolted". They just pull out.

Usual method of doing that is to stack up washers or rocker ***** or something on them, and run a nut down on it. With it bent like that though, that's not an option.

Might want to just cut off the bent part, run a die down over the remains to thread it, and then use a nut.

 

those are pressed in by the looks of them.


I've never had to pull bent studs but I'd guess you'd try to hammer the old one 'straight enough' and run it out with the right tool or a stack of washers and a nut. Pressing a new one in may be a challenge with it on the engine. Or even tapping and threading in a screw in type, ie metal shaving into the oil pan prevention, isn't exactly easy. GL
and Sofa on the ball before me with proper advice like usual

 

Really? Learn something new every day.

 

I have a bent one at the moment also. Plan to use the method Sofa referred to to remove it. They have an alignment tool that we plan to use while tapping a new one for a screw in stud.

 

Stud Remover and alignment tool. Amazon like $20

 

Slide hammer on the stud and heat the boss.

 

I wouldn't recommend trying to press in a new stud once you get that one out. The only way to make sure it won't pull back out is to pin it which is something the average person won't be able to do. Best solution is to drill and tap the stud hole and install a replacement screw in stud. These studs do not have a hex base. You install them by double nutting the stud the just screw it into the head just like you would a bolt.

Drain the coolant before pulling the stud. There's a good chance it goes into a coolant jacket.

 

U do not want to repress a stud into the head. U have to tap the hole & install a threaded stud
