Coolant leaking from hard line

[benefitx]

so i was replacing my turbo manifold on my SR20...so i bolted everything back up , go to put coolant in the radiator and it starts leaking from the BANJO FITTING FOR THE COOLANT TO THE TURBO..

i thought it was doing this because i reused the stock copper crush washers

went out and bought some new copper washers from autozone and also some threadsealer...

came home and put it back together and it still leaks even with the new washers...now i dont know if this is because i didnt get the right "CRUSH" washers , i just got copper ones because they are soft and make a seal..

but u guys have any idea? im torquing this bitch down to like 150 lbs

[punxva]

this is a common problem, get yourself some 14mm crush washers. and that should fix your problem

150 ft. lbs ?!??!?!? dude, that's not cool

i exaggerated , but its pretty close...im moving the entire engine...BUTTTTTTT

the good news is that the threadsealer stuff actually works , u just have to let it sit and harden , and i guess the washers also worked....doesnt leak anymore...

permatex? Their high temperature sealer needs about 24 hours to fully cure.

not permatex...its called threadlocker...dont know if its rated for high temperatures but its a coolant line , how hot could it get?

I'm talking about the manufacturer of the product. Most people buy permatex thread locker

[benefitx]

well i guess it was sort of like permatex...it was in a blue bottle and had a thick texture , i tried some out at first , put in the bolt and took it out 8 hours later...it hardened like steel...so i cleaned the bolt and applied the threadlocker, and waited a full 24 hours and filled up with coolant , no leeeeeeeeeeak

Wow, never getting that line off..

GG turbo.

"how hot could it get"...

Maybe.... 700F...

[benefitx]

[johngriff]

coolant gets that hot in a engine?

You used this?

If so.. Thats just like Loctite. Its not made to seal holes, its made to make bolts stay in, and not back out due to vibration..

Should have gotten some thread sealant, or just plain 'ol RTV.

yes i used Permatex Medium Strength Threadlocker Blue.....the bolt came out fine when i did a test run...but anyways....the only time this bolt will come out next is when i do a turbo swap , and it wont require the coolant line anyways

Not the coolant, but the turbo, which this is bolted too. Sorry, this is just kind of bugging me using this as a fix, when you could have just used fresh copper crush O rings, and touched up both sided of the banjo with some 600 grit to get a good seal.

shit...no1 mentioned that b4

[Slow Poke]

Except me on your other thread...

[benefitx]

what is that supposed to mean?

[jdm_eg6]

i had the same problem happen to me. ended up just going with taka turbo lines. which i thought would be a good idea since i could reuse these when i upgrade.

and they stopped the leak right
