Hi all,I've working on a E36 M42 turbo project, and have some issues with the oil temp. I've try a couple of oil (10W60, 15W50), but oil temp in the summer seasons go above 130C (260F). One turners made me a copy of Ireland Engineering Oil DAC, it became super and I've already installed it, but I have one problem. Once installed it, I start the car and saw that the oil pressure jump dramatically. Now is 100psi (6.5bar) and previously was 60psi (4.5bar), which are data when engine is cold. I was afraid to drive with such pressure and after 10-15min at idle I stop the engine, but I could not warm the oil to see how the pressure will drop when the oil became hotter. Before the cap in hot oil over 190F (90C), the pressure fell to 30psi (2bar).
My two questions are:
1. Did someone of you know how wide are the oil vent of the cap and how wide hose I must use?
2. What pressure values is the max of M42 engine, before something to blow?
Now my vents are 8mm and I use 8mm hose.
Thanks in advance for your answers, if wanna more information just write bellow. (:
p.P.: I noticed that I had an oil leak from the crankcase, which before had not happened when drive at low pressure.
Sorry for my bad english
