Using oil and pushing oil out of dip stick

Inspected the cylinder and the piston and they both checked okay, no scaring.Removed the old piston rings and installed the new piston rings and clocked them correctly. assembled the piston and installed them. I used a universal piston installation tool for installing the piston into the cylinder. Removed the engine sump and replaced the crankcase gasket. Then I removed the rocker cover and replace the gasket. I then installed the new breather tube. I admit it took a while and some help from my mechanic friend, but is done and running like new

cylinder wall was not scared. replace rings cleaned piston. cleaned valve. reassembled. ran like new.

Question: Breather Tube

deepdiver

what is the breather tubes function and what would cause the top end to come loose and where does the bottom end connect? top came loose and was blowing oil. thanks

Hi deepdiver Purpose is to carry crankcase gases passed thru the breather valve assembly out to the air intake so the gases can be reintroduced to the intake via the air filter plate/ or box. If your breather tube is blowing oil, remove and clean the breather assembly bolted to side of engine. Clean the tube of oil also. The breather is somewhat fragile, so do not push on the disc inside it. There should be a very small amount of play in the crankcase breather assembly disc (or valve). Yes, the breather assemblies can go bad with gunk and neglect.

not sure what you mean by breather assembly. this is model 31D777. type 0233E1, 18hp. would you have a part number? thanks

DeepDiver The smaller Briggs OHV engines have this breather assembly. I know you have seen them before bolted to the side of Briggs engines.

Your engine has a BREATHER TUBE, BREATHER COVER, and REED VALVE . The cover and valve act together as the breather assembly on YOUR engine. The reed valve acts as the disc in the smaller breather assembly does, basically a one-way valve. Lets crankcase gases out, but nothing back in. I have a 17.5HP like yours. I have not had the oil blow-by problem though. Those parts are in DIAGRAM D

The bottom of the breather tube most likely plugs into the back of the air filter housing on your model.
If your carb has leaked some gas into the crankcase of the engine, the resulting excessive pressure could push oil out past the reed valve; through the breather tube into the air filter housing on your engine. Check your oil level for overfill and gas smell.

Perfect fit and got the Ramblin' Wreck going again

Nothing fancy, but the OEM part (ancient) had finally hardened and cracked, and rather than continue with electrical tape I took the plunge.
