    You get blow by when the rings do not seal properly anymore.

    blow by is from worn out rings,or you could have one that is sticking. its when the combustion inside your cylinder is leaking past the rings into the crankcase of the engine, then that pressure comes out your breather tube. thats the white smoke that you see.

    if you have oil vapor and air coming out of the breather?
    would that be a ring issue?
    This is on a rebuild with 8 hours on it.

    how low is low? what are your numbers for all 4 cyl? get a squirt can and put some motor oil in it then squirt some into your bad cyl. if your comp comes back to normal then its the rings, if it still stays low or doesnt come up at all its usually the valves that are the culprit,or head gasket etc..

    but if your saying you have alot of blow by, i would guess the ring is stuck or broke being a rebuild with only 8 hrs.

    what did the spark plug look like when you took it out to check compression. are there any silver deposits on it.
