- This video show's how to fix a left side points housing oil leak. I had a bad points housing, the rubber gasket was old and leaking, also pinched rubber tappet gasket, and old worn points gasket.
This video shows my procedure that I have got from many forums. Please do not attempt if you are not confident. This is in no way a manual for how to do this. This movie is meant for information and entertainment only. I hope this video does however help someone fix and troubleshoot their oil leak. I will show the bike running in another video. Please thumbs up and leave a positive comment.

JEEEEEZ don’t hammer on that aluminum with a steel hammer! No wonder you’ve got leaks
At 9:19 you can see a hole in the green Honda gasket under the forward tappet. I don't see that hole on your replacement gasket. It is an essential hole where oil flows.
I've got this leak on both sides. I'm taking my engine out and doing a partial top end rebuild with all new gaskets, seals and wellseal joint compound. It aint going to be leaking when once I've finished with it!!!
You know those hex bolts that you used to tighten the cam/point housing to the engine with. Do you know where i could find them? I used the old screws that came with my bike and they are stripped to all hell. I couldn't tighten them enough and now if i run the engine for 5 seconds oil will come shooting out of that loose area. I prefer not to use Phillips head screws again, so i you could give me a link or the specifications for those hex bolt screws you used that would be amazing! Thank you in advance!
Hey Doug C, I have read on many different Honda forums that the Honda screws are a hardened steel. I also have found them to be able tighten up better because of the larger head. I agree they don't look good. Also yes I agree about the dead blow, didn't have one at the time, and "got the job done" with what I had.
Thanks for the comment
hey nick....I have the same issue but on the opposite side, the tach housing on my '70 cl350 is leaking from behind and blowing down the side of the bike when riding. just wondering if you know, would it basically be the same procedure? ive heard you have to pull the motor and remove the top end to do it !!!
You can do the exact same procedure on the right side. Usually it's a pinched rubber gasket. Put them in the tach housing first so they can't get pinched. Next be very careful the paper gasket doesn't get pinched.
silly question: So we slightly see you wrenching at the cam chain tensioner before and after removing/replacing the housing, I assume to remove all tension to the cam chain, were you unbolting the tensioner housing from the bike? what precisely were you doing and to what effect? I'm only curious as I need to follow what you were doing so I can replace the tappet adjust o-rings since that's where mine is leaking from after a mechanic did a top-end build. To be terribly honest, messing with the cam chain freaks me out a little so any explanation as to what to expect at that point (pun not intended) would be great.
Thanks so much for posting this, so noobs like I can know what visually to expect.
No problem, if you don't loosen off the tensioner you won't get the points housing off. You need a bit of slack in order to remove the points housing. Don't worry about removing the tensioner, this will not mess up the timing.
Just don't obviously turn the engine over for any reason, until you have the points housing back in, and tensioner back on and readjusted.
Also you probably have good or ok tappet rubber gaskets. But they were installed incorrectly. Manually inspect them if they look ok, they are probably ok. The problem comes from a bad installation. My trick is to put the rubber gaskets into the back of the points housing first, so there is no chance of pinching ( which is most of the time the problem ). Also make sure the gasket is installed the correct way, there is only one way and is easy to see. I have that in the video.
Good luck, let me know how you make out
Nick where did you pick up the electronic ignition?
