Just picked up the new 95 S2 tonight. Made a 150 mile drive to pick up and it drove back great except for I think I got some oil blow off. It came (I think) from a hose from behind the battery that leads to under the battery to the crank case I think. It was the only thing that looked like it could've shot oil all over. It wasn't a HUGE amount but enough to get on the rear left fairing, rear left blinker, rear fender, battery cover, heat sheild and hypercharger. I appreciate the help.  | ||

You might be able to see the oil on the faring. Its not easy to pick it up with the oil being such a light color.  | ||

Is that Edelbrock heads? Sweeeeeet! And looks great in white. Most likely: rocker box gasket gone. Replace with the new metal one and you're good to go. The hose in question is the tranny breather, which will spray oil if the crankshaft seal goes, which allows engine oil into the primary case, displacing the tranny oil out the hose. Rocker box gasket is better. But only by a bit. | ||

Yup those are Edelbrock heads. It has a small edelbrock package. Heads, pistons and intake manifold. I'm alittle confused about what your saying. The rocker box gasket is gone. So does that lead to the oil spray and what is suppose the hose suppose to be hooked up to? I'm still in the process of learning how to work on these bikes. Thanks. | ||

That oil is from the transmission vent hose, my S2 did it on long highway trips, it was pressure bleeding out of the crankshaft seal into the primary forcing the oil out. After I rebuilt my motor and replaced all the seals it stopped doing it. | ||

Is there any easy fix that will work of should I change the gaskets (which ones). Also what should the end of the hose be attached too? Thanks! | ||

Put bike on a rear stand so its straight up and then pop off derby cover to check trans fluid level --should be at bottom of clutch basket.If there is too much you will get spew out that hose.The manual recommendation is too full.If there is a bunch in there you may have leaking main seal forcing engine oil into trans.Keep an eye on engine oil level and see if it drops.Or get fancy and put dye in engine oil and see if it ends up in trans.You need to make sure its coming from this hose as some one could have routed breather hoses back there when they put on heads and you are getting engine spooge.Get a catchcan and hook all hoses into it.I use a Jaz--not too pricey and works good. | ||

Manual sayes to use 32oz in trany if you put in more than 28oz it will come out... Like Fireman Jim said check that first... | ||

If you go the dye route, check your tranny oil before you put the dye in the engine oil. Some tranny oil (Mobile 1 75/90 for example) will fluoresce by itself. Maybe due to sulpher content (might also be why it smells so much...). It doesn't take much dye to make the oil glow. If you have a crank seal problem, it will glow brighter. If the seal is bad, it's not really that big a deal to change. The insertion tool makes a snap! Brad | ||

Cool color combo, How tough is a white/white S2? | ||

The hose doesn't attach to anything at that end. Its just to let the primary case breathe. My thought was that you didn't seem sure that the oil actually came out of the hose. A more likely source of oil all over the place is a rockerbox gasket failure. I don't see any oil on the frame at the hose end in your first pic. Nor do I see how oil could get from there to the rear left side. Clean the bike and take a short ride. Maybe wrap a face cloth (loosely) around the end of the tranny breather hose. | ||

I appreciate all the help. I put it up on a rear stand today. Checked the oil while the engine was cold and its at the lower line. I didn't get to check it before the ride home so I have nothing to go against other then its where it should be. Tom. I'll take off the derby cover (circular part that has 2 bolts right by the shifter shaft?) and see whats going on in there. While I'm at it I'll poke around and see if I can find any oil around the rockerbox gasket. If not I'll take alittle ride and wrap the breather hose. Sportyeric, I'm still kinda unsure if the oil came from there but its the only place I could think of where it came from. I really don't know where and what the rockerbox on a motorcycle is so I have to check the manuel tom. and locate it. I know it seems alot unlikely that the breather hose shot all that oil out but I looked all around and thats the only place it looked like it could come from. There was oil on the frame, on the battery case with the look of it being blown toward the front by the pattern the oil was going but I don't know how it could end up on the right fairing, right rear blinker, rear side of heat sheild and even on the rear of the hypercharger. I checked my pants and I didn't see any oil. I'll take a closer look but I don't think I'll find any. It almost looked like someone threw oil on it. I'll locate the rockerbox tom. and see if thats the likely spot it came from. If all of those don't look right I'll get some dye. Where do you get it from and what is the cost? Firemanjim where did you get your jaz catch can? I'm going to take off the hypercharger and put my force on so I'll have more room to play with. I seen some real sweet billet set ups that I'd love to get!!! (Message edited by 97s1 on February 15, 2005) | ||

Also it wasn't spewing oil all the time. It was just that one moment because when I got home it wasn't any worse. The previous owner said it could've been the downshifting I was doing on the highway when I was at about 3k and downshift to 4th to get the rpms higher for a smoother ride till I hit about 70mph then upshift again. I was going about 75 - 80 for 150 miles. I had to downshift several times because i was following my wife.

Derby cover has 4 bolts and is to rear of the 2 bolt inspection cover--that ones for checking primary chain tension.Rocker cover is 3 piece assembly holding rocker arms and covering them(valve covers on cars)prone to leakage on later Buells.Not so much an S-2 thing though. | ||

If the bike had been sitting for a long time, oil from the oil-tank can leak past a check-ball and fill the crankcase. When you start the bike up, the excess oil gets evicted out the breathers to the air filter. From there it can blow back. I'd assume that the seller wouldn't have the nerve to sell a bike with a serious leak without telling you. Here, at least, he'd have a liability to fix it. So if nothing happens next time you ride, you haven't a problem, perhaps. The rocker-box is the polished aluminum at the top of each cylinder. The gaskets where they connect to the (rough-cast) heads can fail and cause a (sometimes) major leak. An updated gasket fixes the problem. S2's used the same gasket as all the others so if FMJ thinks it is less likely to fail on an S2, its only because S2's are damn near perfect. BTW, many thanks for the hat, Jim. | ||

The previous seller said he changed the rocker cover gaskets when he did the heads. When we started it up and I took it for a 20 min test drive no oiled spewed. I haven't rode it yet. So I'll post up when I do and try to give this thread and ending. Thanks. |
