Oil leak from hell

Left front bolt hole in the intake as well as right rear bolt hole both pass into oil chambers (not pressurized) that can leak.

hey dan, whats those go for today, last week it was 40 bucks, i hear the price of metal just went up hahahahha
 
Yeah, you say that now....but when you get here and find out I ate all the left over brownies it'll be a different story I bet!! :rofl_200::rofl_200::rofl_200:
And like I was saying, you did what? all the brownies?

It's not to hard to replace the seal and o-ring. I did mine this summer. Nice not having the little oil spot.
 
mine did the same thing. ended up being the oil seal on the output shaft it drips on the exhaust and burns off.
Thanks much for the input. I can feel oil behind the middle gear cover, but it never hits the ground. Wish it did. Only leaking hot, and burning off like you mentioned.

Would not sealing those bolts cause my bike to look like it's burning oil like a 2-stroke? And keep smoke wafting out of the pipes after shutdown? I think I put in equal length bolts in all the v-boost mount holes when I put it back on. Would that open up something else or mess up those chambers/cause the oil to take a different path?
 
I don't think that much oil would come out of the manifold bolts, if I understand what your saying right. You're talking quite a bit of oil. Check your valve cover seals good with a light running hot. They can spurt a lot of oil.

The intake bolts we are talking about do not go into a pressurized portion of the head. It's just into the counterbore for the head retaining bolt/nut.

That makes sense. I think mine is definitely on the inside because that blue smoke is coming out the pipes quite a bit. I'm going out to warm it up and have a look for outside leaks right now. Can the valve cover gaskets cause leaks inside and out? It seems they could let oil just drip in when the valves open and close.
 
I suppose the intake could leak under the flange of the intake past it's sealing oring. This could suck oil into the engine. About the only other place would be the waterpump but that would only get it into the coolant. If it's sucking it into the intake it should look oily if you can get a peek down there (may need to take the carbs off to see in there well enough)

No other place it can get in without some internal engine part being worn (valve seals, head gasket, rings, ect...)

Pipe smoke greatly reduced. I'm still getting a smoke source on the right rear pipe and something is coming out of the exhaust, but I can't figure out exactly what. You can't see the surface source smoke in this vid, but it happens a bit more after a throttle blip (which is more like a bbblblliiiiiiipppp because my sync is terrible).

I was also thinking, what about RXP or some other carbon deposit blow-by remover stuff. The valves looked pretty crusty when I looked in the intakes while the carbs were off in the first place. I guess it's possible that it is getting sucked in there and burning a bit at a time. Maybe new intake gaskets? (please please please) I'm going to take off the right rear pipe cover when everything is cooled down and see if I can locate a drip or deposit of some sort there, too.

That's what I was thinking - I had a car sitting here (uk) for 7 months over the winter, and when I first started it, it smoked like a bitch for the first day / 50 miles or so. Then it cleared up - guess it was all old fuel and condensation etc
 
People sometimes get water on exhausts when washing their vehicles and when they start them the water puddled on the exhaust evaporates and condenses when it exits and gets in contact with cooler air...
 
You sure that's not fuel or condensation?


Man, that would be great. It's possible. I did find a little oil weeping from the lower front seams of the motor. I might actually need gaskets for those. I'm going to clean it up and start it a couple more times, change the oil, and see what happens. I think I've been so pessimistic about this whole thing that I'm instantly going worst-case. It's been working out so far and I'm feeling lucky. I'm sure I'll be back with more worrying.
 
It's very common for them to "smoke" like that when they are warming up. Usually after they have good temperature built up the smoke goes away.

OK. I'm going to sync tomorrow with my homemade sync tool. That's supposed to be done with a warm engine, right? I've got my fan set up and I'm ready to go. Just didn't want to mess up the silicone I put on those intake bolts. I will probably try a compression test sometime next week just to check things out a little more thoroughly. Oil change tomorrow, too. It looks low at idle, but I'm ready to go searching for that info now. Thanks for all your help, guys.
