Engine builder brain trust. Bought a long block eight years ago, said to be rebuilt. 2.2L E with S pistons and cams. Had John Dougherty grind new Mod Solex Cams since the engine still has E heads...All good. Last year after new cam timing/rocker etc. did a leak-down and all cylinders could only come up to 70%. Good thing at least all the same.
I had mention this on an earlier post and most said leak-down number won't say much at this point.
Now, finally ran the engine on a test stand to brake-in cams and see what I have. I also have new PMO's, S distributor, MSD ignition. Ran great, no leaks, carbs adjusted, brake-in oil 20-50 Valvoline. Did leak-down after a half hour running (2000 rpm). Nice, four cylinders now at 4% and two between 12 and 14%. Not bad considering I was at 70% and still no Load being added. Now the big question, the drained oil looked like ****, looked like lots of metallic. Oil drain plug only had the average little amount of smudge. Why does the first oil look so funny. Thanks, Mark
