Hello folks! Read through a few posts here similar to issues im having but needed more specific advice. I bought a used wright 52in walk behind for my daughters birthday, it has about 500 hours on it and was owned and maintained by a landscaping company. They told me it burns oil pretty fast and the mechanics there said it was most likely the piston/rings. Never dealt with those before but I am willing to learn and don’t mind the time or labor to fix it. It runs great besides needing to bring a case of oil with us lol! Smokes a bluish tint at start, once she’s runnin don’t see any smoke except a small poof here and there but nothing crazy. I took the spark plugs out and took a picture. I haven’t tested the compression yet but will do that today. Any other tests or anything I can look at to diagnose this? There is no visible oil dripping anywhere on the outside. Thank you kindly for any help!
-Susan

Oil enters the cylinder either past the rings , past the valves or at the very worse case through a crack in the head which includes blown head gaskets
The head gasket is alloy and rarely blows but you test this by removing the dip stick after running for 10 minutes /
IF smoke rises then the gasket is gone .
To test for a crak in the head or a worn valve seal or slipping valve guide, remove the rocker cover.
This relieves any pressure on the oil in the head to force it into the cylinder
So if it stops burning oil when you do a test run, no rocker cover ( it will be very messy ) then suspect the head .

However if your mower has the right angle rubber elbow connecting the air filter, I would suspect that the rings are gone.
Had one earlier this year , both cylinders glassy smooth
They got a quick hone, new set of rings, problem solved


This customer has a bagger on the mower and it was sucking a mile of fine dust from the bagger into the cylinder .
remove the rubber elbow , put your damp finger into the carb throat and wipe around .
If it comes out with dust on it then the rings / bore will most likely be your culprit .

The elbow is a big problem as it does not seal particularly well and is quite difficult to fit properly .
FWIW the customer found a Donaldson filter 2nd hand which ended the fine dust problem.

I will give that a test! Don’t mind messy :) ty for the help! So I’ll let it run for 10 min, then check to see if I see smoke coming out. I’ll update.
 
Take off the valve covers and then have someone crank the engine while you watch, you should be able to see where the head gasket is blown.
