Yesterday, with some help from my 2 boys, I got my '76 2.0 short block on the engine run stand. I need help setting it up. It's late 2.0, complete, all stock, EFI. I'm looking for any info, any help at all. I've read few dozen threads about engine stands, but most of them deal with yokes, adapters and such. I need help with wiring and actually test running the engine. If local guys can stop by this long weekend and land me a hand, you'd really do me a solid and I'll return the favor. I'll serve beer of your choice. (IMG:style_emoticons/default/beerchug.gif)

Posted on this thread as well: Ready for break in- need additional info
Personally I would not run a new engine unloaded for that length of time. The cam is not the only thing to break in. The cam manufacturers want their ass covered and they could care less about any other engine component as long as they don't have to warranty the cam. Rings are also critical in the first hour of running. If you don't put the engine under a load quickly the rings will not likely seat as fast as you would like or perhaps forever. Steady RPM being the worst. When you load an engine, gas pressure increases, goes behind the rings and increases the ring to cylinder wall pressure. This pressure is critical for sealing and is also critical that the pressure takes advantage of the sharp honing in the cylinder and to break in the rings. The cylinder walls quickly "glaze" after the engine is fired up, friction is lost and you are stuck with whatever you got. Every engine component has a special need for break in....don't focus on just one. Some engines get assembled with NO OIL ON THE RINGS to aid this.....it's that critical. My recommendation is to fire it up, get it quickly on the road and load/unload...load/unload A good way to do this is stay in second or third gear....step on it hard, let it rev and get off it....cruise (to cool) and repeat 10 times and allow to fully cool....Start over I have seen far more people ruin a new engine (usually a smoker) from loving it than driving it like you stole it. Everyone has a different opinion on break-in so YMMV....good luck |
