Turbo oil feed line screw keeps spinning

No that's actually a plastic housing that's pushes down when you insert the line. The picture is my old oil cooler. The new one is definitely pressed in all the way with the gaskets. The hole is just slightly stripped.

I ended up ordering the loctite thread repair kit. It says it can work to 128 ft pounds. It should have no problem handling 89 inch pounds. So simple. If that doesn't work then I'll have to do helicoil and order those angle attachments. But I don't see why it wouldn't work. Thanks for all the info everyone.

Am I seeing an o-ring in the oil inlet? IIRC you should have 2 o-rings on the tube. I'm wondering if you are having troubles with the screw because an o-ring is preventing you from push the tube fully into its hole

that is hard to say, it does look like an O-ring in there. makes me wonder if it got cranked down because it would go flush. best to triple check before doing it to the fresh threads and making a bigger problem.

Yes but your only making tiny threads because your 1/4 thread is effectively tap drilled at 6mm. This is not a proper repair. Not saying it won't work but for a critical connection like this I'd want it done right if it were my car.

Just did this today... Took me about an hour... Had to use a right angle drill... Didn't have one, luckily found someone who had one. I started and i think the drill was my only hiccup.. take your time and measure the depth of the hole and put electrical tape on the drill bit that comes with the heli coil. Didn't even knock the lip of the oil line..perfect fit.
