I have had my Bike running for 4 days now and have been noticing a small amount of oil coming down the left side cylinder barrel. Any ideas what this might be besides the cylinder head gasket. The other side is dry as a bone almos looks a little crispy. Always has since I got the bike. Like the paint was burnt off. Any ideas or a direction would be great.

On my recently acquired bike what I thought was a leaky head gasket turned out to be missing top seals on the push rod cover tubes.

Take a close look. My rocker boxes were leaking at the bottom, front. Oil has a ninja-like way of looking like it's coming from one place, but really coming from another. Plus, a blown head gasket would have other symptoms.

Plus, your other thread indicated that you may have overfilled the oil tank. Once, I put too much oil in my '79. And it started coming out of everywhere.

pushrod tubes, rockerbox base, rockerbox spindle, oil line banjo connections could all be suspect. -j

and you only had leaking on one side and it wasnt major leaking either it seemed to be more of a trickle thing? and it only seems to be doing the leaking when I ride it. Today is gonna be the first real day Im gonna let it sit since I got it back home from having the carbs re-built.

Mcqueen that was the first thing i thought of, but since i flushed the bike i havent had any over flows, but do you think that oil would stick around and trickle like that for a couple days? in one spot?

McQueen

It could. It's life. If my rocker boxes' bases and pushrod tubes WEREN'T leaking, I'd be suspicious.

I overfilled it once. Oil made it's way out. And since I didn't replace/reseal any gaskets, it still makes it way out.

Right on, I have to take it in to get looked at anyways because i keep keep fouling plugs. Guess its because of air mixture? Ever heard of custom pipes, they were on there when i got the bike, but causing the plugs to faul out in 3-4 hours. The jets a really high needle, i guess to compensate for the air flow for the pipes because each is a straight goose neck to the right side, and they dont connect. Shouldnt there be some type of regulator? I dont know if this place is just trying to get me to buy new pipes or if i can set the needle to run for the pipes that are on there. But I have had to put in a hotter running plug which i know isnt good for the bike.

McQueen

Has anything been done to the motor? Just the pipes?

Welcome to the forum.

First of all, you don't specify what bike you are talking about. Second, a picture is worth a thousand words (or maybe 2 thousand in this case).

blown head gasket causes a loss of cylinder pressure and doesn't leak oil. so everyone is right to tell you not to look there yet.

clean all the oil off of your bike. then run it for a minute and blast baby powder at it to see where the oil leak is starting.

grandpaulz literally knows more about these bikes than 4 haynes manuals. if he told me bashing my face on the bike would fix it, i would take a shot of jack and do it. listen to that guy.
