Short story - billows smoke and oil vapor out exhaust, starts great, runs great otherwise.
Long story - recently purchased machine. Was used by landscaping company and fleet maintained till 2019. Owner sold company and kept machine for home use. Less than 5hrs since little or no maintenance during home use. Had oil leaks from rocker cover, lh side front and rh side from oil fill cap down. Cap appeared to have hole drilled complete thru cap...? Machine had light smoke but ran well and sounds solid. Machine starts quick, runs smooth and had power.
after significant cleaning needs lots of maintenance items.
first thing I replaced was oil dipstick as had old ribbed one and the oil cap. As soon as oil cap was replaced machine had near constant billowing smoke and heavy oil residue from exhaust. I removed the vent tube from valve cover to turbo inlet and it was clean and clear.
since the only thing that changed was redirecting the crank case vapor to the intake and therein increasing case pressure slightly I'm tryin to figure out the next diagnostic step.
I suspect there is either a head gasket leak to the pushrod tube, engine is out of time(skipped a timing belt tooth) or the engine is tired. Any additional ideas are welcome.
Plan to compression test and check timing as next steps.
