Wynn's engine oil stop leaks?????
Hello z people. I'm still trying to plug my gasket leak without changing the gasket (I guess i really am dumb), anyone used this Wynn's
magic in a can stuff? Does it work? Does it wreck your motor? I guess it's worth a try, it's 10 euros a bottle over here.
Many thanks for your feed back. I put some liquid gasket where the leak was and it held up for an hour and then it started to spray my right boot
again. I'm pretty sure it's the rubber 'o' rings that cover the oil passages on the left and right end of the cylinder head.
The Wynn's stuff says it 'renews' the 'o' rings etc and stops the leaks, sounds too good to be true, but when
you're lazy and desperate you'll believe anything right.....:D

I agree but way cheaper than a gasket set and all the time needed for a top end strip. I don't believe that there really is such a thing as a
quick fix.
My gasket leak isn't that bad it's just that it comes out on the side of the cylinder and the wind whips it right up all over my boot and
the bottom of my jeans - it was probably standard fair for a BSA or one of those Brit twins but this is not what I expect from my jap bike, even if it
is nearly 30 years old.

Did you have this leak when you were using dino oil Cactus, or after you went 100% synthetic?

Luv, the leak was their before the fully synth but seems to have gotten worse, it's probably due to the fact that the oil is 5W-40 and not
10W-40, so it could run thinner.
I heard that the Wynn's probably contains w50 oil and so thickens up the oil, but I don't know for sure. I'll probably give it a
shot, it seems to me it's worth a try as with GPZ I'm not ready for a full strip down yet.
I'm even wondering if some heat resistant resin based glue might do the trick as it really is just a small gasket leak...

How bad is the leak?
There are a few things you can do to stop a *small* leak but the magic snake oil in a bottle stuff is usually just another way to separate you from
your money...
If it's a case or valve cover gasket leaking the solution is pretty easy...
Get the leaking area spotless clean and free of oil (brake cleaner or carb and choke spray work great here)then use some Permatex Ultra Black or ULtra
Grey (depending on the color of your engine) and stuff it into the leaky area as much as possible. it does need to sit overnight but it will
"quick fix" it.. not a permanent fix but it'll buy you a little extra time.
You can also use this stuff in place of a gasket if both surfaces are flat.
This stuff is easily concealed so it won't make your motor look like crap after you use it and it's not your ordinary RTV, it seals WAY
better.
Yamabond also works great but it's a mother cleaning the stuff off later on when you do the real fix.
now if you have a leak where there is pressurized oil passing thru, the only fix is to tear down and replace the o-ring or gasket.
Never ride faster than your angel can fly...

Wicked, I can see you've also been here. That's exactly what I've done, but with stuff we call autojoint bleu (because it's
blue) over here (ie France). It's the top head gasket and like I say the autojoint held up a good hour on a long trip, but on the return it
started dribbling again.
I stuffed more in there, each time using brake cleaner to get all the oil off the surface. I should be able to keep going like this for a while, but
I can't rev it up to 11 000 any more it leaks out even worse.
Still this is all good argument for buying an ER-6f, the downside is I really need to fix the bike to get a good sale, and if I do fix it, my argument
for buying a new one goes out the window:D I put a for sale sign on it and if someone offers me loads of money they can have the best z650 in the
south west of France, leak or no leak...
Actually I could probably do a strip in under 2 hours if I organise myself, I'm a very slow, methodical type, most of the time, I'll just
have to motivate myself to that point. Otherwise I really do have a sweet motor.
Still like I say it's fueling my project to go for an ER-6f and no more oily hands for the next 10 years...

In the(bad) old days,brake fluid was used a stop leak in auto trannies,and power steering pumps.It does the same thing,swelling up seals,O
rings,etc,but it was a last resort,used on tired iron.

Ooo, sounds funky, I guess if it works in an emergency, like get me back home, but I'd rather go for the Wynn's than the brake fluid:D
Still, thanks for the info - nostalgia huh.

I would worry as to what that stuff would do to the wet clutch.
I'd go to my local hardware store and get a meter or so of 50mm rubber tube. Then drill a few holes in it and run some copper wire through the
holes - wrap this around the cylinder so that one end of the tube catches the oil - run the other end to the chain - presto - automatic chain oiler
:D
For a really cool look use braided stainless tube.

Autojoint on the outside (yamabond etc.) + the mysterious elixir (that looks suspiciously like brake fluid) was poured surreptitiously into the
tunneled recesses of the mechanical labyrinth and it's holding up for now.:)

Update. My leak has completely cleared up for now and I'm running the bike as usual, but am not pushing it past 9500rpm for the time being, so
I'm happy with the product and the results so far - so maybe being lazy is ok after all:D

I just read in one of my japanese kawasaki bike mags that this motor, which was also in the zephyr and then the zr7 is known for it's leaky head
and they recommend always using a brand new rocker box gasket and high quality gasket seal, which is always a good idea anyway.
Up till now i don't like gasket goo too much and most of the time I use a smear of grease to hold the gaskets in place but will use gasket goo
from now on.

I assume you were joking about this, but I bought about 3 feet of tubing from the hardware store today to try to contain my oil leak for a month or
so.
I just bought a used '83 550LTD and it has a fairly nasty leak which soaks my left foot in oil on the expressway. The problem is I'm in
an apartment at the moment and will close on my house (with a garage) at the end of the month so I just want a way to ride the bike for the rest of
the fall without the extra "waterproofing" on my left boot. I'll try to fix it correctly when I have a garage to work in.
So yeah... as ridiculous as it sounds, I'm gonna try your suggestion this week. :o

I'll let ya know how it works (if it works). I don't think I'm going to do the chain oiler, I just want to route the oil to
anyplace but my shoe.

My leak seems to be coming from here:
[img]http://homepage.mac.com/kevin.becker/motorcycle/leak.jpg[/img]
My first attempt with the hose trick didn't work so well but I think it would if I get another section of tube and cut the holes better.
I also tightened down the cylinder head nuts a bit, which seemed to help a lot more than the crazy hose rig. I'm not sure if I should tighten
them more or not though. They are already tighter than the 17ft-lbs recommended in my Clymer manual. For a permanent fix, it seems like I will have
to take a lot off to replace the gasket. I hope I don't end up with a "parts bike" to sell on eBay after I'm done with it.
:(
