I have a Toro Z Master(think its a 2005) with 30 hp Kohler engine that was rebuilt under 100 hrs. ago by a toro certified tech. (cant take it back to him...out of business)
I have an oil leak this season that I cannot find. Have tried and tried but there are so many covers and heat shields etc. When I start the mower and look for it I cannot see it but once I start moving oil blows from what appears to be the top of the motor all over my exhaust and I can see it puddling on top of one of the heat shield under the intake...which is above anywhere it could be leaking.
Might be blowing up from the front of the engine.
Point being I cant take the top of engine apart to look as I wont be able to start it to see whats leaking.
Anybody know common leak areas on this motor I should be trying to inspect. I have cleaned motor and tried to just observe but like I said too many covers, shields in way.
We would need the model of the Toro or the model and spec number of Kohler. The Kohler info maybe what need if they can a separate IPL of the engine to look-up the setup.
You're quite fortunate to have a piece of equipment with a Kohler engine. Many engine makers only want to supply an operator's manual and charge a good penny for anything technical. Go to Kohler Engines: Home and get a complete online manual.
Turns out that under the crankcase breather cover is just a little breather filter. Have one now as well as a new breather tube and will try that. No check ball or reed.
One note if you don't mind make sure you count for all the bolts and screws you remove. I had a customer that dropped a bolt when this breather plate gasket and just replaced it with one from his spares. Later I found it when he brought the motor in locked up. The bolt manage to get behind the flywheel. When it did it took out the flywheel magnet and the alternator.
