Ive got a permacool oil filter relocater kit with an oil cooler in line with it. anyway the lines, filter and fittings all get quite hot.. and you can feel the pressure going thro the lines no worries. esp the ones too and from the oil cooler. However the oil cooler itself is stone cold to touch. even after a few hard laps at the track when oil temps go to 110 degrees its still cold. yet i have oil going too and from it.

wtf?

If the oil cooler is damaged why would it make a difference which side of the filter its on ?

I'd have thought filter first because if you lose an engine the shrapnel shouldn't get past the filter and get caught in the cooler core , one less thing to replace with the rebuild .

Is there a thermostat in there somewhere? If not it shouldn't matter which way it's hooked up, it'll still flow in the configuration you have.

The horror stories are from ones with the 2in-2out style oil filter relocator/thermostat in one types (hks/trust).

Anyway, you've said the lines and fittings up to the core are hot and you can feel the pressure in there so there must be some flow through the thing, or your engine would already be dead from lack of oil.

You don't have an inline thermostat hidden in the guard somewhere that you have forgotten about do you?

Can you feel a difference in the lines going into the cooler and coming out? If the line coming out is cooler then the radiator is doing its job. According to Earls you should filter the oil before it goes through the cooler. Will try to upload diagram.

exactly it makes no difference. and you should always send the oil through the filter first, then the core, then back to the engine. set-ups with the thermostat built into the filter head do exactly that. when cold oil travels from engine, to filter and back to engine, when hot it goes engine to filter to cooler then back to engine.

as it turns out i mistakingly hooked up the outlet on the block sandwish plate on the centre of the oil filter... and from there it was looped thro the oil cooler.

swapped these two lines around on the oil filter attachment and then ran it and within a few mins the oil cooler had warmed right up... so now its flowing as it should.

hope no damage has been done :( :S

That sounds like what was done to mine. After a few power runs at 8000+rpm and 475rwkw we checked to see how hot the cooler was.... It was cold. :O

We drained some oil out and it was full of metal.

Towed car away, had engine pulled out, found the bent crank. Now just waiting to get it rebuild again.

If only I had my tuner fit the engine instead of another local so called "mechanic"

yeah I can't imagine your engine will be alive. if the cooler was plumbed up so nothing was flowing through it (i'm not sure how btw?) then that means oil was coming out of the filter head area and then going no-where. but if you just have one 'out' hose and one 'in' coming off the engine filter head adapter then it shouldn't matter which way you connect them to the cooler.

oh wait, i see. you hooked the engine 'output' line to the remote filter 'output' instead of the filter 'input'. you could be in trouble, might get away with it. but if the engine is still running then that's a pretty fair sign it will be ok.

Would most likely have popped through the oil filters drain back valve too as if oil was being fed through the filter the wrong way the rubber flap that stops oil draining out would been stopping flow but I guess eventually it just would have forced it's way through.

oil analysis, its like $50 and mainlube.com.au do them, highly recommended, will tell you if you have shagged the bearings or anything.

this is something you want to find out now before catastrophic failure, it could be fine though.

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
