Iam looking for some knowledge ,what would cause exessive smoke to come from the breather tube. p.s. no compression in #2 cylinder, broken ring? stuck valve? or?????
Typical blow-by. Rings typically the issue. Run a compression test first. On all cylinders. Squirt some oil in the cylinder and see if the compression comes back up. If so then the rings the culprit. Real easy to pull the intake. You sure can get a good look there on valve activity.
If you want to run the engine without an overhaul, look at cheap possibilities before you freak out. Look in sparkplug hole of dead cylinder while someone turns engine over several times BY HAND. See if both valves look like they are closing...a stored flathead will frequently sieze up a valve or two, usually lightly, so if one is staying open first try just pushing it closed with a probe of some sort after shooting some penetrating oil down past it. If it moves, more oil and several open and push cycles will likely freeitup. Zero rather than 10 or 20 suggests looking at valves before worrying about the rings there. Your compression is pretty low, but should allow the beast to be used until overhaul time. If Ol #2 can be gotten back online, give the thing a heavy dose of Marvel Mystery oil in pan and in gas...your rings might well just be sticky, and a good soak in miracle elixir may improve thigs all around...though while the MMO is in use it will of course cause some smoke itself.
Hey, i have similar problem, there is no smoke but oil coming out of the breather. the oilpressure is extremly high! pistonrings?
thanks bruce iam planning on pulling the heads and that is what i was thinking ,always nice to have a second opinion.
If the engine has been sitting a long time, it could be a stuck valve but it would run terrible and be noisy if a valve was stuck. You can run it without the plug in that cylinder and see what the valves are doing.
