Is it ok to reuse arp studs?Can they be torqued multiple times? Always see used sets for sale in the classifieds,just wondering.

 

thats supposed to be one of the pros of them is that they can be reused over and over again.

 

I would assume it would depend alot on weather or not the holes were bottom tapped or not. I would think if the studs are installed to where the added stress of "cutting" its way down until tight then you may not want to have them "cut" the rest of the way in a new block.

That being said I am having mine installed in a diesel shop right now and told them not to bottom tap the holes. I have read atleast a half dozen posts in the last few years where the tap snapped off flush in the hole. Plus the manufacture, ARP says no bottom tapping is necessary.

 

oh man that would ruin your day!!!

 

man i hope that doesnt happen to me when i go to do mine. i hear there is a clearance problem if you dont bottom tap, any one have this experience?

 

Do not ever re-install, you have no idea what abuse they have been through.

 

I agree. This is one place where I wouldn't use a "used" part...

There may be a clearance problem but I wouldn't know because I bottom tapped. It's not a big deal to do and you'll be surprised how "soft" the block material seems to be... very easy to cut threads with the tap. There is clearancing that needs to be done on the back of the aluminum injector wiring hold down plate no matter what, unless you want a massive oil leak at the back of your engine....
