I have a variety in sizes of shims, along with a few .24mm/.010 shims and none go that thin. I'm leaning towards taking the flywheel to a machine shop and having them shave .005 off to give me wiggle room for clearance, then if need be I can always add thicker shims to get to where I want to be. |

Two shims is ok.
You should not check the end play on an assembled engine with no shims, there is no way to know if the flywheel is touching the bearing, OR if some other part has hit first. |

I tried it with the 3 shims and it wouldn't budge. I felt no movement at all, so then I decided to try with no shims and attached the dial indicator to get an exact measurement so I would have an idea of end play. I even measured end play without the flywheel on and it was the same. I don't have the pistons on yet so it's easy to push the crank back and forth. I remember a topic about going with 2 shims and the consensus seemed to be a bad idea that the 3 shims were needed for the specific reason that 3 shims create less friction then 2. If I was certain that 2 shims would work and not cause me any more headaches then what this engine has already given me, I would go with 2 shims in a heartbeat. |

I hate to say it but this is another one of those things that can be figured before the case gets closed up. But since you are beyond that point your idea of taking some off the flywheel would work. Not sure about using 2 shims never had to do that. I suspect bearing is made a little too thick causing loss of clearance. |

I just figured it's the same case, flywheel & crank so the same 3 shims that measured .030 SHOULD work. It does sound like the thrust bearing is on thicker side which would prevent proper endplay. |

It is less confusing to set the end play before assembling the engine.
To check the end play with the engine assembled, used two thin shims, because the crankshaft clearance without the flywheel may be as low as .020
Will two shims work ok? yes.
Consensus?
I don't worry about that. |

Did the 20 minute break-in on Sunday, then did a 6-7 mile drive yesterday and all seems well so far. Going to change the oil, and check the valves and I'll give it a go from there. |

Changed the oil and.....more aluminum. I flushed everything real well before putting it back together. I can only hope it's residual and/or normal wear of things breaking in. The oil was much darker then what I think it should be for being run only about an hour. After changing the oil I took it for about a 25 mile run. It runs like a champ, but for how long is the question. |

I was hoping you solved it.
Was it just a bit of a sheen in the oil? Or more? |

You could see on the oil sump cover a silver sludge. |

Did you use the same oil cooler? Did you remove oil gallery plugs and really clean case? Might just be residual contamination from before. I’d buy some cheap 10w30 and flush it several more times. It’s not uncommon to see some stuff after first run especially if you aren’t running full flow filtering. Don’t throw in towel |

I removed both pressure relief plugs and flushed it the best I could for quite a long time. I used the same oil cooler and flushed that several times as well. I'm not using an oil filter. Still the stock filtering system. I'm using Valvoline Racing Oil 10W 30 which is high in zinc. Used that for the break-in and for the first oil change. Not cheap. |

It’s normal to see some stuff first change or two. I’m glass is half full optimist here. |

Hopefully you have an oil filter/pump installed. _________________ In Stereo, Where Available! |

There are real benefits to having a filter but I’ve built many an engine without just like VW. So Without the filter I’d buy some name brand but not fancy or expensive 10w30 and flush it several times. It should settle down after 2 or 3 changes. What have you got to lose? |
