does anyone know if i use the "oil leak stopper" sold in auto stores will work if i use it on my blast. it has a small leak and i was concerned it it will not work right since i only use HD oil.
is there any major difference in HD oil and other manufacturers like Penzoil, Mobil, etc.
thanks

Is the "leak stopper" something you pour into the oil? If so I'd recommend against using it, just fix the leak.

Is the leak stopper something you apply to the outer surface of the leak area? If so I'd probably not advise it and instead suggest fixing the leak.

Where is the leak coming from? Most of the known oil leak areas are fairly straight forward fixes or updates.

yes the stoper is a poured into oil type.
the leak is toward the front of the engine block.
and the left side.
isn't it expensise to get something like this fixed. i know in cars i would have to remove the header and replace seals.
im also not to concerned in spending to much money since the bike is a 2001 blast and its market value is like 2k at most.

IS it really "leaking" or just a slow seep that spreads out? Do you actually get drips as such?

I think I would probably re-torque the bolts for the primary cover if that's where it's coming from. Maybe they've worked themselves loose just a tad or maybe the gasket has compressed enough to spring a leak. That's what I would do, but I haven't actually looked at your leak, so I don't know.

Can you get a pic?

The leak stopper stuff contains a chemical which will cause rubber seals to swell slightly. I don't think this will fix the leak on your Blast which sounds like a gasket leak. This stuff is OK for a car with 100,000+ miles on it but I wouldn't put it in a bike, especially one with oil hoses that could be softened by the stuff. Post a photo of the leak on your Blast and maybe we can give you a better diagnosis. If it's a primary cover gasket leak, that's pretty easy and cheap to fix.

I believe the 2001 Blast uses a paper rocker box gasket. They start to leak after a while. Is this what is leaking? If so the fix is to install the metal rocker box gasket from later year models. The knowlege vault probably has more detailed info.

Found a link: http://www.badweatherbikers.com/buell/messages/20164/34080.html?1109095986

search for the word rocker

Jl... No pics but he says it's toward the front of the engine block. I don't think it's the head, but we'll know when we get pics : ).

Buell2001b...

If you can find a pic of a Blast on this site and doctor it with MSPaint (or your editor of choice) to show where the leak is that would be good too...

Also... Try the thumper forum.

If it's toward the front of the engine block, and it's on a 2001 Blast, it's almost definitely the rocker box gasket. If it's still a slow seep, then it's a good time to fix it now. It will get progressively worse. I don't think it's that expensive to fix it, but there are plenty of folks in the Thumper forum that have experience with it.

Also, the Blast is so easy to work on, why would you even think about adding something to the oil that would probably mess up your engine and cost you a full replacement in the long run, rather than actually fixing it??? I just don't get it...

"If it's toward the front of the engine block, and it's on a 2001 Blast, it's almost definitely the rocker box gasket."

Maybe I'm confused : ). Isn't the rocker box about 6-8" above the engine cases? Are you talking about the base gasket?

I'm probably confused...

Take a picture and post it.

I'd never use that stuff to fix a leak, fix it properly.

What's wrong with duct tape, or duck tape for that matter?

JB Weld it!



Just cover the leak! That would be WAY better than putting anything in the oil!!

(Don't actually do this! Just kidding about the JB Weld! SERIOUS about NOT adding anything to the oil!!!)

M1combat--You're right, the rocker box gasket is above the cases, etc. It's just that when it starts seeping, you usually don't notice it. By the time it's actually noticeable, it's seeping down onto the cases (starts to look like a base gasket leak), and soon after that, it's seeping REALLY FAST. lol...
The reason I'd bet that the rocker box gasket is the culprit is that the gasket is paper on all Blasts before midyear-2002-ish. After that, the factory went to the metal gasket, because the paper one WILL fail, eventually.
So, to answer your question, you weren't confused, I was unclear. Which, I've found, is usually the problem when I'm involved. lol...
