Beer Baron it is 8AN!!

been thinking about oil cooler ( among lots of other mods ) . What are the good oil cooler kits for r33 gts -t . just for light track days, off street drag. would not want to pay more than $400 for whole kit including plate, connections and braided hoses ( 10 - 15 layers ) any suggestions.

go return it, money back gurantee I think?

but most of JustJap parts are chinese crappy knock offs...

Save yourself the headache and go get a Permacool relocation kit & thermostat & and quality B&M core. Same price-"ish" but 300% the quality!

From where?

thread is going on 2 years old....ha

anyway, the jrr cooler is fine. you will need to teflon tape all the fittings.

I've installed 2-3 of them.

on your budget I'd be looking at a second hand trust kit. you might score one for $400 but may need to spend another $100 as they are usually around $500 or so second hand. excellent kits. I've used probably half a dozen of them now on my own cars.

You should never ever have to teflon tape oil cooler fittings. If the fittings were good enough quality you dont need them.

Ask any decent fitting company, Earls, Aeroquip, Mocal.. if you ask the question they yell back at you.. NO! Keep that AWAY from oil systems. lol.

Im assuming its the bsp/jic/npt end of the fittings that leak, as thread tape wont fix the an fittings, as its not the thread that seals. Sure earls may say not to use teflon tape, but they sell the liquid equivalent. It is actually better to use a sealant on tapered thread fittings, as they arent meant to be excessively tightenedor damage to the female union can result.

i dont use the o ring fittings. well i modify them. they are a pain in the ass. best thing to do is to put the fitting in the lathe and machine off the o ring lips and use a copper washer with locktie. never had any leaks after.

added bonus is when you want to undo them,just the hose end undoes and not the whole fitting.

thread tape is a big no no. ive seen so many bb turbos fail from a stray piece of thead tape blocking the oil feed in the turbo..

if it is the kind that just squashes a o ring with no recess for it then just use a washer..

also you should check that the fittings that screw into the filter/adapter block dont go i to far and restrict the oil flow. i always have to take 3-4mm off the total length of the thread.

oh, the braided hose with the crimped ends and red stripes on it. jj ones have -10 ends but the hose is 1/2" (-8an) in size...

thats what i did to fix it, i just put the fittings in a lathe and used copper washers, 2 years later or more and still to this day NO leaks.

I picked mine off eBay, but American Autos have it, eBay has it new, a few sponsors on Nissan Silvia have them as well. They're great value and you know it won't leak. Just one problem, they don't have holes fit sensors.

Also fk, blast from the past LOL

Have you guys ever tried the hydraulic washers with a rubber o-ring inbuilt?

I had a issue with a leaking fitting with a copper washer and used one of these and it fixed the problem straight away

Dowty or Doughty washers

Dowty or Doughty washers

That's the one

Don't know how true it is but when I asked the guy at the hydraulics joint what pressure they were rated at he said the ally fitting I had would break before the washer seal!

I got one of the light weight 19 row blue oil cooler kits, and oil keeps leaking from it.

I have tried to replace the o rings with some good quality wurth ones which made no difference.

I then got hold of some locktight paste stuff (hydrolic thread sealant) which is suppossed to hold 1000psi once cured AND IT STILL LEAKS.

Does anyone have any ideas on how i can stop this from leaking? should i just use thread tape?

Its leaking on the fittings that screw onto the sandwitch plate on the block.

Has anyone had this issue before? how did you fix it.

I hate oil leaks more then anything else, leaking 300v chrono is driving me INSANE!!!!

i just throw the sandwich plates away and use a decent earls one with tapered thread AN fitting..... no leaks, no friggin around with thread tape which can fray and dislodge... ultimately block an oil gallery.

I fitted a greddy cooler kit to an s13 yesturday and it leaked from the plug that holds the thermostat. it was missing an o-ring, so much for buying a jap brand cooler to avoid problems!
