    Does anyone know what this engine noise could be?

    Took it out last week and everything was fine. Went home and changed the oil and plugs and started it up and it was fine. Went to start it then next day and after about 15 seconds of idling, I heard this noise. No oil pressure light, compression is normal, no flakes in the oil.

    I've never met anyone in my life with worse luck.

    Sounds like valve train noise to me. Seems to be running smooth enough. Timing chain adjuster/guides?

    How can I check for that? The noise does seem
    To be coming from the blower area. The engine is new with less than 45 minutes on it.

    Do you have a stethoscope? Hold the end against the block in different places. You'll hear where it's coming from real quick.

    Think maybe a loose flywheel?
