Lost oil pressure 4,000 miles after 117 upgrade
« on: September 25, 2018, 12:11:22 PM »

So yesterday while going to work, my stator started going out, so after work I limped it back home and on the way home I lost all oil pressure, I just did a 117 Upgrade 4,000 miles ago and its been running fine, when I upgraded I added the S&S Oil Pump and cam Plate. just did a Oil Change the day before so I cant figure out what let go, later today I'm pulling the Spark plugs and the Oil Pressure Sending unit and cranking the motor to see if Oil comes out......I'm Stumped and the Shop AzKikr Customs who did the work closed up last month, I'm screwed

May want to screw in a manual oil pressure gage, pull the plugs and fuel pump fuse and crank it
until the gage tells you weather or not you have pressure. It is possible the sensor is faulty. Cross
your fingers!

Well I could tell it was not getting oil as the lifters started getting noisy, I did shut the motor down right away so as to prevent any damage. Will see tonight, I would really hate to buy a new bottom end.

Could a plugged oil filter cause this?

Ok move forward and fix the issues by inspecting the cam plate and oil pump.

Yes right when I lost Oil Pressure the lifters started chattering, so that's when I shut it down, I did not have a chance to check it last night but hope fully in the next few days. I just think its strange that right after I changed the oil and filter this happened may be coincidence. This new S&S Oil Pump only has 4,000 miles on it and it had been working flawlessly with great pressure. cant think of what would fail internally on the oil pump.

If it was the S&S blue plate and pump, look at the plate in the area where the pressure gear rides for abnormal scoring. May be a problem.  :nixweiss:

just open & up and check it.the S&S pumps are supposed to tolerate more run out than a stock  (or other aftermarket pumps) but can only take so much.

Time to measure runout, and look for debris in the cavities.
