[Vwdiesel] Not diesel, Type 1 1600 single port oil pressure

[dieseltdi at verizon.net]

 Check to see if your oil pressure relief piston is stuck.  That is an easy check from the bottom of the engine. Just use a wide screwdriver to unscrew the cover.  While you have it out, check the spring length to make sure it is correct. To set the fan shroud vents it should be done cold.  I don't have my book here in front of me but as I recall, you loosen the bracket and release the thermostat from the bracket (bolt on the bottom) and move it up to a fully open position.  Then you move the bracket until it  rests  on the top of the thermostat and tighten down the bracket and then reattach the  thermostat to the bracket.  This will bring it back to the cold, closed condition. Just remembering from the top of my head so you WILL want to check this.  I would try these BEFORE you go to the trouble of replacing the oil pump.  Hayden

??so, I got the bug running and noticed when cold I am seeing these oil pressures
less then 50 miles on??the??rebuilt motor I did 8 years ago.I put new rings in, new main bearings and cams, rear main seal, not sure if I put in a new oil pump???The original motor only had 75K on it, maybe 175K, but I don't think so, this car sat for 10 years before we got it, 11 years ago.I kept it original with single port heads, new valve guides and new exhaust valves installed, not intakes.
so, oil pressure is way low when hot, can not get more then 10psi.rule of thumb, 10psi per 1,000 RPMidle, about??10 psithis is on a cold start with 10W-40 motor oil.1K about 15psi2K about 20psi3K about 30psi
Thermostat spring is hooked up and may not be opening the cooling louvers all the way in the bottom of fan housing, so I will re-adjust it when it is hot to full open when hot, not full closed when cold and it may not be opening all the way, so I could be getting the motor too hot??But, I know it is moving them some, I see it move the arm that pulls a cable to open cold air intake on the air filter.
So, if after re-adjusting the thermostat spring to be full open when hot, and I still have no oil pressure when hot, 
I need to change the oil pump, right???that is the logical next step?>
let me know what you all think.
