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[ffrocks].

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 [thumb] 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

Yes you need to use photobucket or something of the like.

To embed them here use,

I look forward to the how to.

You will get a Rep point by doing so.

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

first you need some good ole ARP studs
http://i1320.photobucket.com/albums/...ps1aef18fd.jpg

next you'll install them via instructions included and using the torque lube
http://i1320.photobucket.com/albums/...ps11b5537c.jpg
then you'll notice the studs are way longer then the stock bolts
http://i1320.photobucket.com/albums/...pse1971aa2.jpg
then I decided to trim down the stud after installing the nut and marking the stud and removing them as to not put metal shaving and grindings in the engine while making sure I don't take too much off and hurt the integrity of the stud
http://i1320.photobucket.com/albums/...ps844d10b8.jpg
this will also reduce the amount aluminum you have to remove from the bottom crankcase assy
http://i1320.photobucket.com/albums/...ps052edaf5.jpg
above I marked the area where your stud will hit if not notched out also below
http://i1320.photobucket.com/albums/...ps70468a7d.jpg
next you will need a tool of choice mine is here
http://i1320.photobucket.com/albums/...ps2e73d4e1.jpg
and perform your notching I also used a air powered 90 degree cutoff wheel
http://i1320.photobucket.com/albums/...ps02c93c7b.jpg
http://i1320.photobucket.com/albums/...psf4432d8a.jpg
the angles are messing with how the clearance looks but its evenly cut out around the nut
http://i1320.photobucket.com/albums/...pscea5e7db.jpg
then ur done with this issue
http://i1320.photobucket.com/albums/...pse919c024.jpg

then you'll be done and happy
