Re: Universal 5424 oil mist from dipstick
Mark, on most of these engines, there are two things you need to consider: 1) the dipstick has a rubber boot where it seats on the dipstick tube; 2) there is always some slight pressure out of the breather hose at the top of the engine.
1) replace the dipstick with a new one that seals
2) route the breather hose over to the air intake or tap it into the air intake manifold
