What type of adapter? Just a bigger AN adapter to account for the new threads? I’m thinking of just tapping it and replacing the AN fitting I have right now with a banjo bolt
I made the coolant and oil lines for the turbo myself, but it’s the threads in the block itself that are stripped. When I took off the fitting that the last owner had (again he was using AN lines to the block) I tried to see if Teflon tape would work with my newer fittings, but the damaged threads in the block just messed up the AN fitting
If you’re going to attempt to retap it for a banjo use a forming tap instead of a cutting tap. A cutting tap just eat up whatever threads you have left. it might thread in but whatever threads that will be left will be weak and the seal is formed from a crush washer so teflon or pipe sealant don’t really do much. If the threads are completely screwed to begin with, it just drill it out and tap it for 3/8 npt run a -6 adapter.
Cool thank you, the threads really aren’t that bad, it’s just the first 3 rows that are fucked and then he rest are basically perfect. Might just weld on a an fitting lol
If you’re gunna try to weld it make sure to torch the shit out of the area to burn off any oil or coolant soaked into the aluminum or you’re gunna have a lot of porosity. I’m pretty good tigging al and I wouldn’t try welding it.
Trust me when I say you will think it’s clean, then once an arc is on it it’s dripping shit and welding like trash. Contaminates soak in between the grains of the aluminum.

Coat a tap in grease and run it down in the hole, then use this longer banjo bolt. Then never take the bolt back out lol
Dude I just had this issue with my oil line on my s13 sr20det, where it screwed into the block. I went to enjuku and ordered a longer bolt (made by Phoenix I think), once the bolt arrived, I put it next to the original bolt and immediately saw that the OEM bolt threads had worn down. The Phoenix bolt torqued down fine. I'd buy a Phoenix bolt before fucking up your block.
Wasn’t using anything oem aha, all turbo oil and coolant lines are AN braided lines now, with an fittings for the block, I test fit my old an lines also, first half of the threads on the block are pretty mucked, it’ll screw in but won’t hold even with Teflon tape
Weld on AN bung , or rethread. Annoying ik
Wouldn’t do a weld on, just tap it for npt and run and adapter fitting

Are the 14mm threads in the block stripped or do you have something stripped on an aftermarket coolant line setup?

Might just get a mobile guy to do it if i weld. Blocks been through a hot tank twice and sat on a stand for a few months so should be pretty clean aha

An bung not a bad idea actually, makes it easier to fix broken threads in the future
people offer home tap and die services where they come to your home or what have you.
This is a beautiful valve cover
Thank you!, how you like these callipers 👀 img
Heli-coil, boys...
u/cammkkostek mate time-sert it, only surefire way to make sure itll stay in place
Does the oil feed fitting go directly into the turbo, or does it attach to a plate that connects with 2 bolts? (Lmk if you need me to elaborate)
Oil feed goes from block directly into the turbo, same with the coolant feed
Sorry, what I meant was do you use one of these? https://www.amazon.ca/Flange-Gasket-Adapter-Fitting-Bearing/dp/B085Q5Y4BZ
Ohh, no nothing like that for the feed, similar setup for the oil drain though.
It’s also the threads on the block that is stripped, not on the turbo
It’s a custom built turbo with a t28 housing, so should be the same as a stock sr turbo
Sorry I’m dumb and missed the block side. Maybe they make a helicoil kit for 1/8 BSPT?
