I have been fighting oil leaks for a while and it got so bad that I pulled apart all my TN fittings and oil pan/ spacer today. Is there something I can use to help seal everything better?

 

I find teflon tape helps seal the best.

 

use permatex high temp thread sealant on all fittings I think I used high temp cooper rvt gasket for the oil pan got it all at autozone, I have no problems

 

i use thread sealant (not thread locker!). It works well and never have issues.

On the oil pan spcer, I use black permatex; it is designed to resist oil better than the other versions of permatex.

 

When you wrap the threads with teflon tape, wrap the threads only once. Wrapping them a bunch of times will only make the tape bunch up and come off the the threads.

I would also check out a plumbing store for thread sealant. I have used RTV on some of the ships I have been on and it works great.

 

If you go to Auto Zone (maybe other auto parts stores as well) they sell rubber O-ring kit wit hassorted size o-rings. Buy the o-ring kit and use the closest fitting O-ring. That's what I did.

Do not over tighten the o-ring. It will fail.

I swear on Honda-Bond for sealant. I find it works the best. I found Permatex doesn't sets up in the presence of oil.

 

Interesting

 

First send a picture of your fittings tookin apart laying next to each other in order. I may be able to help. I just went threw this battle.A/N male/female pipe fittings with some britsh **** that won't ever seal. OR you can just have the fittings brazed.

 

you can't use on pipe threads, though. on straight threads, a crush washer or an o-ring is the right way to do it. on pipe thread (NPT), use sealant or tape.

 

are you sure you didn't wrap the tape in the wrong direction? if you wrap in the wrong direction, you will unwravel the tape with screwing in the fitting.

I usually wrap the tape about 3 times around the threads and never have issues.

 

NPT and BSP are differnent. NPT is national pipe thread.....it is a a tapered thread. also, the pitch is different than British, too. on a 1/8", the US has 27 threds per inch as opposed to 28 TPI on the british. BSP (aka BSPF) stands for British Standard Pipe - Parallel. this is different than BSPT which is British Standard Pipe - Tapered.


on our cars, the oil pressure sending unit thread is 1/8" BSP......there may be others, but that is the only one I know of.

 

Yep. Its been my experience that wrapping threads many times yields results which are no better than putting nothing on the threads at all.

 

use permatex high temp thread sealant on all fittings thats what they make the stuff. You will have no problems as long as you give it about 2 hours to dry. It is in little white tube at any auto store. I can see using the tape but in my past experience it won't hold up for a period of time. And If you get that tape inside your block It can clog small openings which will not be good on internals.

 

I decided to go with the Tef tape. Its the easiest part of my venture this morning. I hate the oil pan spacer and if this doesn't seal properly I may look to see if I can get it welded to the pan or buy an aftermarket one.

 

I would get the aps pan if it doesn't work out for you. I hope you get this oil leak issued resolved. Good luck.

 

No leaks. On my bolts for the oil pan, I'll put some on the threads to help seal also.

 

Oh yeah... I forgot is was NPT. O-rings won't work. I was confusign it with my Greddy pan. I had the AAM spacer, but I got rid of it. So many parts so much confusion.

 

Tis what I used.

Think if I put some in my TN turbo it won't leak?

 

haha, at the TN turbo. if it was only that easy.


we use a lot of Grey permatex , you have to be careful when you grab the black cause there are two different kinds of black in the same packaging.

 

black is the most oil resistant so great for oil pans but I've also used the high temp orange on several oil pans with never a leak. I use teflon tape wrapped in the right direction a few times and have never had a leak.
