Oil pressure update

I don't know if anyone remembers my post awhile back about idle oil pressure but here I am again with an update. I haven't tore down my engine due to finances but I have talked at length with the machinist that did my work. This is the deal. When I tore down my engine, it had 10 over bearings in it. It still has 10 over bearings! When questioned at length, the machinist said that it was not important to measure any I.D.'s, and my oil pressure, 8 psi, was cool. He did not grind my crank! He didn't even measure It! He said that he did not measure inside diameters and that he didn't even check ring end gap. Told me that it was hard to measure I.D.'s and be accurate,just polished an already worn out crank and put it back in. He also replaced a rod that had spun a bearing and did not check the I.D. of the journal. Now I know what went wrong. Now what I need to do is talk to some engine machinist. If there are any on this board, I would really like to talk to you. The one good thing that has come out of this is that I want to become an engine machinist now. I have been on disability for quite some time now, I applied for voc-rehab and have been accepted. I am going to an engine machinist school in Mississippi. It's at Jones County Junior College and it's a year long. Anyone out there with a shop interested in hiring a disabled vet after I finish this school? It's a year long. My only goal is to be a damn good machinist and get back on my feet. Sorry for the long rant but this engine build has set me in the right direction. Later

Funny thing about life...........we never know what circumstance may alter the direction of our future. This oil pressure thing may give you a whole new career.:D :D :D

I think you needed a new machinist anyway. What DID he check? This reminds me of the old joke: What do they call the guy who graduates at the bottom of his Medical School class? Answer.............Doctor.

Moral of story, there are good Doctors and bad Doctors. The same goes for machinists. I hope you graduate at the top of your Machinist class.

Good luck.

I think you just found out the difference between an engine builder and a machinist.
A machinist may know how to bore a block, turn a crank,etc.
An engine builder will know what amount of clearance he is machining for and why.
