I really want to get my car back together tonight so i can move it to a safer place before the storm tomorrow (almost had tree fall on my car last hurricane where i'm at here basically in between Charlotte and Sarasota county).

Anyhow, the kit comes with no instructions and that would be great if i had used any AN fittings before. I know u need teflon, i know u have to wrap it a certain way, but i don't know where to use the washers included, or how exactly to tighten the fittings (i can't really get a 19mm wrench or 17mm wrench in between the compressor and exhaust housing of the turbo, there's just no room).

from what i could find from other clueless people online, is that u can't use the 90 end on the coolant return side cause it hits the arm of the wastegate actuator, some people flipped that arm over and it fit, others just said to use the straight end of the SS line like i have in the pic below.

this is pic showing that the 90 wont fit that i found on Nico:

This is what i did for that coolant line:



Now this is where i'm confused, in that pic on the line to the right thats not connected to anything, there's a washer between the pipe fitting (i think thats what the end fitting is called) and the AN fitting (the female one that the pipe fitting goes into? haha). As u can see with the line i connected to the cartridge i took that washer out and put it on the other side of the pipe fitting (between cartridge and pipe fitting). I don't think the washer needs to go there cause the end of that pipe fitting (double male ends) is domed or has a flare head and the female fitting it goes into is like cupped:



I was told u don't need teflon or a washer in between these two cause they are flared fittings that seal when they are tightened, is this correct?


Then the oil feed line below, i know it comes with washers for the banjo fitting side, but does the other end just need teflon on it? The side that goes into the turbo





So basically:

i know a lot of u are gonna get confused cause i don't know the right terms for any of these parts but i want to know which end of the lines should go where (i know the oil line, but coolant ones). And i want to know where to use the silver washers and where to use teflon for the coolant lines.

I found these 2 pics of how this guy on Nico said all the lines should be done:

Also, whats the easiest way to tighten them, and how tight should they be?

THANKS

 

the silver washers are for like, threading into the block, or on something that isnt tapered.

i put teflon on the threads that go into the engine, and turbo.

basically, thread the outer piece of the an fitting onto whatever its going on, (turbo, engine, coolant neck) tighten that, then figure out which end fits where. if angled hits something, use straight, and vice versa.

one bigger line should go to your coolant neck, and the other behind the head to the coolant line.

heres a pic of mine, you can kinda make it out.

 

easiest way to tighten them might be to take the maifold off, and give yourself some access room.

 

sweet thanks a lot man

 

oh, and the washers pretty much replace the factory washer on only one side.
so, anywhere that had one of those stupid dual washer things, gets one silver.
on the side that threads in, the an fitting will seal itself when tightened.

 

the washer goes on the part that threads into the turbo because its just a straight pipe fitting. its not tapered and theres no flare. the other part has a flare and seals just like a brake line or clutch line. as stated, teflon the nonflared end and put the washer on, and the other end doesnt need anything. i think youve got it figured out though.

 

actually, just im me.

Yeesh. How did I know the links to the other forums would be wrong.

OK. The general information.
The double male fittings that go into the block and turbo center section... These are called "metric to AN adapters". That's because they're AN on one side (the flared side), and they're Metric on the other. This is what you're using on the coolant lines. The metric side goes into the block and turbo. They seal with a crush washer betwen the adapter and the block/turbo. These are usually copper, but yours are aluminum. These do not require teflon tape anywhere.

The banjo fitting is the one with the big hole in the middle. This seals to the block with a crush washer on each side. The banjo bolt goes through the middle. So it should be Block | crush washer | banjo fitting | crush washer | banjo bolt. This is used on the oil line where it attaches to the block. These do not require teflon tape.

The last kind of fitting that you have is an inverse flare fitting. That's the other end of your oil line (that goes into the top of your center section). Techincally this is an inverse flare (IF) to AN adapter. The taper you see on the inside of the fitting will mate with the inverse of this on the turbo. You do not use teflon tape here.

Now about sealing. There are 3 ways to seal something. First is a crush washer. This is what Nissan uses all over the place on turbos. The copper or aluminum is forced to conform with the 2 opposite surfaces, which seals them together. They also make one with an oring inside the crush washer. These are used on fitting with straight threads (SAE or Metric). The second type is the pipe fitting. These have tapered threads and use teflon tape to seal. Because they are tapered they will bind, and they use this binding to seal. The teflon tape fills in the small gaps. There are no pipe fittings in these turbo lines. The third type of fitting is a flare. This includes AN fittings that are flared to 37* as well as all other flares that are usually at 45*. By forcing these 2 surfaces together, a seal is formed. No teflon tape is used here.

Armed with this knowledge plus righty-tighty, lefty-loosey, you should be able to install these lines.

 

Thanks a lot for the info man, got to it too late though. I used teflon on all 4 of the metric fittings for the coolant feed/return, and i even used teflon on the inverse flare fitting for the oil feed at the turbo .

Started the car up and in 10 seconds leaked a pint of oil out of oil feed line at the block. I don't think the aluminum crush washers they supply you with are worth a damn. I have it tightened down pretty snug. What do i do now??

*all the other fittings aren't leaking from that brief 10 seconds of running

 

thats where mine leaked from, and it ended up my block was slightly stripped.
