Bobcat 610 Oil cap blew off and leaking oil

[noelmbobcat610]

Hello All,

I'm hoping to get a bit of advice on a bobcat 610, I have two problems with my bobcat #1) the power starts off fine when I start the machine but then starts to slow down when I turn it or use the scooper.
#2) yesterday the oil cap blew off and I saw some oil around the engine. I'm thinking maybe there's a clog somewhere but don't know where to start???

Any help will be greatly appreciated!

I would start by doing a cylinder compression check. I am afraid you are going to find one or more cylinders with weak compression. From what you stated it sounds like compression blow by is really pressurizing the crankcase. If you do not have a compression gauge O'Riley's, Auto Zone and other locations rent tools.

Makes sense I will pick one up and start there. Thanks!
Any ideas on the spark plugs? I noticed yesterday that two of them get hot and two don't?
