I know truth is knocking. I'm looking through the little peephole on the door. I know the oil pressure is related to all this somehow. I was just on the phone with Warren at DMCH to discuss it. I did not have the opportunity to observe oil pressure. The car didn't run long enough, but it didn't squeal until after another round of cranking. It did not squeal while it was running. I have determined that the oil pump may need priming to suck from the sump. The oil was so thinned out when I got the car, it was like water. I drained it all, and the oil suction tube and pump probably drained because there was no viscosity (resistance to flow) to hold it in there. I should slap myself because I mis-read the manual. I thought it said to prime the oil pump AT the pump through a little hole. It says "Remove the oil filter and inject some engine oil through hole (A) with an oil can to prime the oil pumps" (Yes, there are two). I may have a small amount of fuel in the sump from other tests. I will prime the pumps as soon as I get home. Warrensays (my favorite phrase) that no oil pressure and squeaking mean a hell of a lot of friction that -may- result in hard cranking (and starting). He feels I should look into this sooner rather than later because I may damage something without lube. I am listening for truth and I believe that this is all related. I think I'll have more answers when I get home. --- In DMCForum@xxxxxxxxxxxxxxx, "Dave Stragand" <dave.stragand@xxxx> wrote: > Well, it could be compression, spark, fuel, or a combination... or something you haven't tested yet. > > Remember, the stated problem is "The car will not run", not "there is a problem with the spark, compression, or fuel".

Since compression isn't the main problem (100psi is fine), the other result of adding MMO is lubrication. You may have a huge amount of friction if your oil isn't flowing. Did you check the oil pressure yet? Anything coming out one of the sender holes? MMO doesn't burn like fuel, even in a diesel, so we can discount that. Friction can account for squeaking (metal-to-metal), hard cranking, and lack of compression (no oil to seal the rings). > > Squeaking like that isn't good. Coupled with the lack of oil pressure, I would really focus on that. You should get at least enough pressure on cranking to get the oil light to go out, and stay out, for about 5 seconds at minimum. Have you checked the viscosiy of the oil lately? Has it thinned with fuel? > > "Truth comes knocking at the door, and you say, 'Go away! I'm looking for the truth,' and so it goes away. Puzzling." - Robert Pirsig. The lack of oil pressure is pointing to the fact that SOMETHING is wrong; listen to it and find out what it's telling you. The car might start without oil pressure, but the same cause of the lack of oil pressure could be the cause of the non-start condition. This little "unrelated issue" could be the cause. > > Zen movie quote: "To hear, one has only to listen".
