Source for new main cap bolts?

Tasca had a few week wait as did VP. Skandix was going to absolutely kill me on shipping but they have many ready to ship.

If you feel like being resourceful, they are M12 x 1.75 x 80 MM and are Grade(Class?) 12.9.

Alternatively, I have a set of Yoshifab ARP Mains that I do not plan to install. We can continue via PM if interested.

Thanks for the offer, but I have a set of ARP mains in there currently. The problem is that the ARP nuts are too tall, which causes the oil pump hard line to not seat properly in the block. My plan is to replace the one offending stud/nut with a stock bolt.
 
I don't think modifying the stud is an option. It fouls by like 0.25".

I ordered some ARP m12x1.75 80 mm bolts. I'll probably use one of those instead of a used bolt.
 
That's what I figured, but I have no idea what other people have done. Josh said it was supposed to fit, but it's a long way away from that. Seems like I have to modify the hard line or use a bolt.
 
Threads aren't sticking out too far, so the stud is seated properly.

Results in like 0.25" of interference with the oil pump hard line. Cutting the stud and nut really isn't feasible.

Keep posted on this please.
Same combo going together soon...

Sure. My plan is to use an ARP bolt instead of a stud in that one spot. I ordered a 5 pack of m12x1.75 80 mm long ARP bolts. I'm hoping they'll have shallower heads and will fit. I figure it'll provide a very similar clamping force and be ok.
 
Wanna sell me an extra bolt? It's either use bolt, cut n weld line if it'll clear inside pan ( have to check clearance) or possibly AN? Idk how hose will hold up inside oil pan.
 
Sure. I'll have to see if it fits first though.

I thought about using an AN line, but I really don't think it would work well. It's submerged and hot. I think hard line is the only way to go. I was going to cut and weld two lines into one, but I'm worried about the weld quality, and if it will seal properly. It's just risky and cheaper to just get a bolt imo.
 
Well my buddy is handy with a tig torch. I prefer the hardline myself. I have a few here I might hack up. Easy enough to test for leaks too. I cant imagine we are the only two to ever run into this. I just had a line hone done and don't want to disturb anything honestly. Fancy 2.5 stroker I'm wasting time on...
 
The ARP bolt works. I'll probably use this unless someone else has a better solution. I'm also going to post a new thread in performance and give it a more related title for better visibility.
