HOW TO FIX AN OIL LEAK ON A HONDA GCV160 VALVE COVER

[@captronrv7]

That valve cover sealed from the factory is NEVER going to leak! Honda just doesn't do things this way! The leak comes from the O-ring on the camshaft shaft, the shaft protruding below the cylinder head with the half-moon end on it. The shaft is held in place by the tab on the valve cover. With the valve cover off, use pliers to gently pull the shaft out about a half inch to expose the O-ring. With small needle-nose pliers, pinch the old O-ring enough to have a hold on it and gently work it off the end of the shaft. If you have a Harbor Freight O-ring kit, the size you want is 010. It's a tiny bit thicker than the original, so grease it up and fit it onto the shaft. It will take a small amount of force to get the shaft and O-ring back into the cylinder head hole, but it will go in with a satisfying "snap"!

[@emil1997h]

This needs to be pinned haha wish I read this before changing the valve cover it was indeed that small gasket on the pin It’s a 6.​8x1.​9 o-ring and it’s for the cam pulley shaft

[@jujuju20121]

Both could be the culprit. I have a brand new GCV170. The GCV170 and GCV200 have a different design and don't have the O-ring with the half-moon end shaft on it. It was still leaking. The valve cover was not properly sealed. It almost fell out when I removed the bolts and there was almost no sealant around the cover edge.

[@norge696]

Good video JB. I use the same gasket maker. Only thing I do differently is tip the engine back so the oil doesn't have to be drained. And when hand tightening I use a 6in extension bottom them out. Wait 60min. Torque to spec. Also the amount of people that DO NOT read the directions on gasket makers is mind blowing. Then they wonder why it leaks. Some have a cure time of 24 hours.

[@GarageGear]

Hey Norge! I figured I’d drain it because I did not know how much had leaked out. Definitely got to read those directions! Need to do it right! Did you see the white board?

[@omarmacias7001]

This is what i found out today as i was getting ready to redo valve cover , tilt power washer back in place to keep oil out of the way, there is also an o ring on camshaft for valves that leaked.replace it too.And that valve cover holds that shaft in place.so make sure that the flat part on shaft is facing valve cover .for a while i thought there was a missing part that holds that shat up in place . maybe thats why it leaked too after redid valve cover. U learn something new every day.

[@GarageGear]

Thanks for sharing Omar!

[@choppa5300]

What’s the part number ? I’m looking for the size for the Oring ?

[@russhenry9232]

Very helpful video and helpful comments by others too. The oil leak is one of the issues I'm having with mine. The other is that while it's running it can't seem to maintain it's throttle - seems to increase & decrease in a rhythmic pattern every few seconds and sometimes after using it for like 5 minutes it will just shut off. Starts back up fine and I can use it again for a couple minutes before it shuts off again. Is that related to the oil leak or something with maybe the fuel filter or fuel pump or something? Sorry, I'm engine illiterate but trying to learn!

[@GarageGear]

Hey Russ! It sounds like you’re dealing with a carburetor/fuel issue. I would check the carburetor out to make sure it’s clean.👍

[@423co]

Watching this got my attention looking at the Honda engine. I thought🤔I got the same engine on my PW. However, mine is the HONDA 190 model. (HOMELITE 3500 psi 2.5 gpm HONDA 190) Looking at the HONDA parts manual, it seems the 160 and the 190 share the same part numbers. I have NEVER had a problem with the HONDA engine. My problems are always with the Homelite parts. Mainly the water pump🤬🤬🤬 Leaks and clogging up. Once I disconnected the soap tank, I solved the clogging problems. Now, the pump is leaking...AGAIN!🤬🤬🤬 JB, you asked what the fines were for water use violations here. None of my neighbors have got a fine, only warning tickets...so far. The commercial use water customers are the bulk of the violations. I'll try to get a water cop to give me more info. The breweries around here use A LOT H2O! 90 degrees here today, I may have to put on a jacket! Been in the 100's last week. Have a blessed-cool- weekend.

[@GarageGear]

Power washers are a never ending battle it seems lol! Too many parts for something to go wrong I guess. When you find out let me know what the fines are. They gotta be nuts. We’re coming up on 85 plus here this week. Pretty muggy too. Have a good week my friend!

[@smallblock412]

For such a simple repair, I wonder how many people would junk it and buy a new one? Nice work buddy!

Thanks for the great video! I'm just curious why you did not mention using the original valve cover? We all like to save money right. I understand it gets bent a little bit when you pry on it to get it off, but it's easy enough to straighten back out. Please let us know, Thanks

[@GarageGear]

Hey Ruben, these covers are made of very this metal and can get bent very easily. It’s very easy to take them out of shape! One little bend in the right spot could lead to another leak. Buying a new one is cheap and highly recommended.

My oil leak isnt from the cover.. it's from that little shaft with the half moon head that sticks out from under just behind/outside that cover.....I'm guessing thats a whole different tragedy.

Hey Chris! My issue was with the cover but I have seen them leak from the half moon piece you’re speaking of. Haven’t done a repair on that as of yet. That could be a complicated repair because that piece is controlling an internal part or two. I believe it’s a small seal going bad. Could be wrong though.

[@mwgrc]

I knew this wasn't going to be a manly video when you pulled the spark plug wire as to avoid and accidental start on a pull to start engine. Then you bent up the valve cover and replaced it which did not need to happen, then did zero diagnostics to see if it was the valve cover or was it the the seal on the timing pully shaft that extends through the head right under the timing belt at the bottom/middle/underneath directly behind the valve cover, which is what it is 99.999 % of the time. Other than that, great video, lol

What was HONDA thinking on this engine. Why didn't they put a gasket on these GCV160s like other honda engines so if you need to adjust the valves you can pull the cover easily. Poor design by Honda. I am working on the same motor and its popping and backfiring so I'm sure it's a valve issue.
