Well after a day of high boost for about 4 hours straight, my top oil feed line on my GT35R decided to come loose. Luckly hardly no oil was lost and oil pressure was fine.

The big question is, how do I tighten it? I can get my hand in there but a regular long wrench just won't fit. I was thinking a stubby open end wrench that has an adjustable open end (do they make those?) or a crowfoot wrench might work as well. I'm trying to avoid removing the whole turbine just to tighten up the one line.

Worst comes to worst, I'll remove everything and do some upgrades over the winter, but I'm obviously trying to avoid that


Any input is appreciated

 

I use a ratchet w/ an extension and one of those wrench ends that slip onto the extension. Forgot what it's called right now.

And most importantly, you need to hold the fitting that screws onto the cartridge from moving otherwise it will strip easy. Those fittings are only aluminum and they are common for breaking. What i did to hold that down was cut down the appropriate size wrench in 1/2 or whatever size suits your need.

 

Refering to these:



?

And I'm kinda lost on the second part. Is there 2 parts to the fitting? One that you need to hold in place and one that you must tighten?

Thanks!

 

Yup, those. Also to even gain more clearance, I ground out the fat sides on those.


check out this pic.
Notice this fitting. The feed line gets tightened to this fitting. If you don't hold it, it might turn and strip

 

Thats exactly the picture I was looking for! Thanks

By any chance do you remember what size fitting it is?

Also I think to prevent this from happening again, I'm going to remove the fitting completly and put some high temp silicone on the threads so it can't back out. Good idea?

 

Don't remember 100% but I think the size is 15mm

The silicone is a good idea. I never had it back out on me even without silicone though. The bigger problem is stripping it away. Your hand torque will overcome the silicone.

 

Yeah I'd just be using the silicone as an anti-vibration method so it won't backout. It'll hopefully stay tight through hand torque.

Since it seems fragil, I'm guessing "hand tight" is good enough?

 

Well, personally i touch it w/ the wrench. Maybe 1-2ft lb torque because you do want both fittings to seal. Doesnt seal at the threads...

 

true, alright thanks for the help bro, I'll be getting the tools this week and hopefully knock it out next weekend

 

anytime, good luck

PS BTW that little damn fitting costs about $25.00.
