Thank you boxter,
Yes that is the cover I have, and I hooked the oil pressure gauge as shown.. I guess they do not show the allen head bolt that is in the way of a socket to get the sensor out.
This is a pic I gleaned from the web.
.
Are the two threaded studs on the bottom where the oil intake with strainer attaches to?
Then it seems that the oil relief valve is in the gallery above where the oil returns from the oil cooler, so restrictions in filter and oil cooler would not affect the pressure.
What is the lower oil gallery doing. The oil comes out at the bottom towards the cooler but it seems to continue also to the filter, is there a secret bypass valve?
My pressure is 32 psi cold idle and does not increase with higher rpm. It actually drops 1-2 psi with higher rpm??
That it does not increase means that my relief valve spring is weak?
I feel that the metal oil cooler pipe is pretty small diameter for a large flow.
And then there is this...d2 oil relief.pdf, also gleaned from the web.. this has the oil filter straight down... it describes a relief valve on the right and a bypass valve on the left.. does the d1 not have a bypass valve and so why not or why does tye d2 need one. Also where the d1 has the relief valve, the d2 has the bypass valve ( oil filter restriction) the d2 has the relief valve on the driver side.
Or am I confused and is the relief valve in the d1 actually a bypass valve.
Ha,
Johan
