Got a bit of an issue with the ca , I have oil coming out off the rad overflow. The engine is a new build with arp studs and metal head gasket. I had the head skimmed and block decked I also shortened the stud above the water pump.
I have only ran the car on tick over to check the timing and in approx 1 minute it emptied half off the sump in to the coolant system which pressurised it and forced it out off the overflow, could my oil cooler have split?thanjs nismo .
Is it easy to loop the coolant lines on the cooler on the CA ?
It’s not easy but that’s what I will try next.
See if you get a big spirt of oil out of the cooler unit
Are you sure there was no dirt or anything on the head gasket when it went on
You can do a full delete on the oil cooler if needs be.Originally Posted by autosri
Thanks for the advice and info, I have found that the cooler has ruptured as I got oil coming out when I cranked the engine. It’s time for cooler delete mod.
Anyone got tips for getting oil out off the coolant
drain your coolant out and put some fairy liquid in instead of antifreeze. then run it for a bit and drain that out.
and Flush, flush, flush & flush again.
Some people pop the stat out and rad hoses off, then run a hose through the engine for a good few minutes.
Are you sure it's shorten enough?
Sounds like it's still tightening on the thread?
It’s defo coming from the oil cooler.
