    coasting in my neighborhood the cam was about to make the car stall with its lumpiness I gave it a 20-25% throttle jump to keep it going I notice 10 seconds later the DIC says low oil PSI and the light is on in the cluster FU.CK mode active. turn car off. waited 5 minutes tried to start it and no lights for oil. drive it the 100 feet to my drive way and let it idle and gave it a quick rev and thats when i got to hear my heart and head explode. It sounds nice and fine before 2.2k. I changed the oil, more metal in it third change in 300 miles. start car again now its a bit more quiet and sounds like its coming from the top end.

    Sounds like you didn't change your oil pump.

    Just curious why would I need to change an oil pump with only 69k on it?? I changed the oil the first time with 60 miles on it then again tonight with 240 on that.

    Sounds like there could have been some of those shavings in your pick up tube... pump ect. How doesn't that make sense?

    are you trying to say that I should have changed it when I did the rebuild or I will need to change it now?

    Did you crank it a bit just to get oil flowing before initial start up? If you didn't I suggest you try it this time. Pull your fuel pump fuse and do like 10 sets of 15 second cranks. Use 10w30 non syn on your break in oil.

    The metal shavings in the oil were from the first second you built the motor... Something was grinding and its not going to stop.. usually a grinding bearing will last about 300-500 miles before it falls apart enough to knock.

    I have to wait 2 weeks before I can even take my car back to the machine shop. I'm testing the oil psi today and installing a gauge.
