I might be wrong, but I think it's too small and VERY expensive. Remember not even the Nismo Z's get a cooler, get a vendor like Stillen or GTM, I think it's a bigger cooling core and costs less.

Bigger isn't always better. You can over-cool your car and get sludge build up if you cooler is too big for your climate.

Chris from Failsafeperformance in tulsa and i pieced together a great oil cooler kit. I went out to the track the other weekend and put in four hard twenty minute sesions and I have had my cooler for almost two months. I am sure he could price out the same kit. Mine has not had any problems or leaks and I have the bumper off all the time and as we are changing things. Like ModShack kit, Chris could get you straightened out with something similar that is great for the money.

do you know what temperatures oil tends to sludge up at. I know manufactures and blends vary but rough temp for most types.

I have to say after GTM sent the new lines, I have not had an issue since. In fact, going up and down the Dragon .. beating her hard in 2nd and 3rd most of the way .. I barely got above 225. Granted, when I was running the ambient temp was in the high 80's.

ok i'm reclaiming my thread, within 200miles of the failure it seemed i had dodged the bullet. That was until the intake valve timing stopped working. turns out there is a little screen that is in the supply line to the cam sprocket and it was plugged solid. they cleaned it out and replaced the sprockets and within 50 miles of the dealership the car started making a horrible banging noise like a loud rumble. I suspected a transmission problem but when i went in to replace the aftermarket flywheel for stock i found some thing even better. there is over an 1/8 of an inch of crankshaft end play on my motor the thrust bearing must be almost completely gone.

What caused this problem in the first place and can it happen to someone else?

Did this happen before or after your oil cooler leaked?

I am not positive. But I can look into it.

OP's oil lines exploded. Oil leaked out. Caused bearing/engine failure. Obviously it happened after the fact.

simons 05-30-2010 07:03 PM

No, what I meant was what caused the screen on the intake cam to become plugged or blocked solid? By what?

1slow370 05-31-2010 02:03 AM

the metal from the bearing drops into the pan and gets circulated through the engine by the pump after plugging the filter and causing it to into bypass the metal then plugged up the screens. it took 200 miles for the thrust bearing to eat away into nothing ness

1slow370 06-02-2010 04:22 PM

2.3mm of end play in the crank it will be getting replaced next week with a new shortblock if the heads aren't damaged

this would have never happened if you had an oil pressure gauge ;)
