I just installed a front oil cooler using -12 lines from engine to cooler.I test drove the car Sunday for about 5 miles. I noticed my oil pressure at speed was around 50 psi
and at idle around 20 psi. The oil temp while driving was about 170 or so. Before I installed the cooler my presure was around 20-25 psi at about 2000 rpm which I think is normal. The motor is new with around 1100 miles and does have a HD oil pump.I also use 20W-50 oil. Is this high pressure a problem or not??? |

Seems to me that any additional elements in the oil system add resistince to flow and therefore increase the oil pressure.
Adding all those lines with elbows etc, the cooler, thermostat add resistance to flow which equals more pressure. Too much pressure in these motors makes for more oil leaks. I don't think you have a problem, just a result of adding the system. For pluming systems, you calculate loss in flow for every elbow 45, 90, etc. Then add losses from the length and type of pipe and of course the amount of head or drop in the system. I don't see why it is any different for an oil system, accept for maybe the change in temperature and viscosity. dr |
