ARP main stud to lower crankcase clarence issues... and how i solved it

While rebuilding my 02 zetec engine I replaced my main bolts with ARP main studs which are wayyy stronger, when doing so even with the correct ARP part used you will run into major clarence issues. I'm currently getting my camera fixed so it will connect and so I can make a step by step of how I fixed it also id like for other people to include how they fixed it... this will help anyone who builds the 2.0 engine in the future. Also for those who think you can reuse ur old main and rod bolts you shouldnt as they are a torque to yeild style bolt that should be replaced everytime.

You can reuse you main bolts but you need to check and make sure they haven't stretched to much, and a lot of people just use a dremel and cut out the part that hits

Yeah, and where is that spec for max allowable stretch, surprise it doesn't exist. One should realize if bolt has physically deformed to stay permanently longer, it has already partially failed, which is what TTY bolts do the first time they are used. It would be quite dumb to risk an engine on that................

You are 100% correct if you reuse a tty bolt you risk wasting all the time and money you put into the engine...

NEVER REUSE TTY BOLTS Just a side note for everyone

am sure this is what you did to get clearance for the ARP main studs.

Excellent. I'd be cutting studs too to keep from having to make the cutouts in girdle too deep, that makes it a bit stronger.
