OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Honda Engines Honda GCV 160

I have the Honda GCV 160 motor on my Karcher pressure washer. Each of the last 2 times I used the unit, it would leak oil from the oil pan seal at the bottom, when shut down. I've replaced the seal both times. I cleaned/inspected the shaft finding no burrs, etc., having no success solving the problem.

I've had this for 6 yrs. Other than changing 1 pump, no issues. It has me stumped. Any help is greatly appreciated.

Did you apply grease to new contact lip? If not it may be getting burned before oil get to it. Also make the seal cavity in the oil pan is cleaned of any corrosion and gaps as your seal leaking around the outside part of the seal instead around the crankshaft.

Thanks...Did apply small amount of grease, the seal nearly fell into place. Will check the seal "fit" area, maybe I missed something.

rkubler avb is right sealmight be leaking from outside to make sure it not leaking from out side make sure casting is very clean then before fitting seal smear fully round outside seal with silicon gasket goo and press seal in wipe up exess goo

Hmmm, You need to press the seal in as it should not just fall in. Otherwords it should present some resist to being install for a tight fit.

What is the serial of the GCV160 and what pn are you installing? Something just doesn't sound right.

My thoughts exactly...I'm guessing it took less than 1o pounds of pressure, by hand, to push it in. Shocked me as I've installed countless numbers of seals of the same design over the years.

As I need my machine running, I ordered a new motor, but plan on tearing this one down, freshening her up this winter.
I'll post how it goes and what I find.

Thanks for the replies from you guys.

Possibly the wrong seal?

I apologize for the extra posts

I looked at the ipl for that engine and that is the correct part number for the seal. It is a 28 X 41.25 X 6 mm seal. Here is the list alternate seals Honda PN.

Thanks, AVB...I'll try one of those, hopefully with better results.
