found an oil cooler f/$125 new in box.
upon inspection it does have a strange imprint on the cooling fins......
doesn't appear to have compromised the integrity of things?
What's a quick consensus?
weird to me to see that
run it or what?
is there a way to pressure test an oil cooler before install?
i also found a OEM manifold drivers side and will think about doing the oil cooler at same time if it helps to do the manifold change out from below as opposed to from the top taking out IC tubes et. al. YES i should have changed it when I had the engine out last year, but manifold/UPGRADED oil filter head had been done in 2012 so I thought don't mess with it IF IT AIN'T BROKE..... actually just left the oil cooler hanging from the filter head as I removed the front cover.
DEFINITELY using the OEM manifold gaskets but wonder
IS THERE ANY DRESSING OR SEALANT THAT CAN BE USED IN ADDITION TO THE GASKET?
i'm worried there is enough erosion on the head itself that a leak will now always form there.....
someone said they've used Henry's roofing tar.....seems like a joke to me?
NOTE the use of an engine brake over the years seems to have facilitated leaks in the manifold.
i jerked the PACBRAKE out totally some years ago= full bore now to downpipe.
A FEW years back you could turn on the engine brake and hear the leak at the manifold instantly whining!
so put a new manifold ala Dormen made in china with the gasket supplied jerked pacbrake out.....lasted 4 years...
i have 3 complete functional Pacbrake actuators, new solenoids etc. if anyone is interested.....
