An Interesting Oil Leak

[RedRocket]

So my Venture has been leaving puddles like a Harley Davidson, and coating my saddle bags with oily goo.

I cleaned off the underside, and then removed the side panels, spoiler, and lower fairing sides. I cleaned everything off again, then rode it to work.

 

When I got there, my boot and lower right leg were nicely soaked, and I had a pool of fresh oil in the V between the cylinders. It was concentrated in the right rear quadrant. My rocker covers look mostly good. They're all a tiny bit damp, but not wet. I spotted the oil lines that gather in the center. After pulling the airbox off, I got a bit of a better view, but not much.

I fired it up, and discovered the oil burping, and seeping from the intake manifold. Check out the pics that will follow

Now I know that the sharp ones out there will say " you're missing a bolt there stupid." but I just removed it before taking the pictures. I tried to tighten it, but the hole is stripped. The bolt looks fine, but had some of the head's thread attached to it when I pulled it out.

Now someone tell my why oil is coming from there please.

Get a helicoil kit and repair the stripped threads. Put the bolt back in and see what happens. I can't figure out why you have that much oil coming from the intake. I a little blowby from the valves is possible, but that is a lot. When is the last time you had the valves adjusted???

That manifold hole doesn't have a bottom. I'm not sure what it runs into internally but I've had oil start to weep out of the hole after removing the manifold. Getting that hole repaired is going to be a PITA, but there's no other way to get the manifold to seal... and get the leak stopped.... Good luck...

Condor's right. There's no bottom on the outer four Holes of teh Manifold Ensemble, that's why Yammi used different Bolt Lenghts and different Bolt Coatings. The shining Bolts go into the outward Holes and the green Bolts on the inwarded Pattern. With a little Luck, you can find a last Piece of Thread on the lower End of the Hole and tighten the Bolt down. I'd use some Silicone RTV to make it seal better. If the Thread is stripped completely, there's a Helicoil or Time Sert fix in Order.

Yep. Been there before. SHiny or the long screws go in the outer holes. Chased that one for a couple of months!

Boo. Should I try some teflon thread tape, and lock-tite first?

Depends on the amount of thread you have left in there. Teflon only seals the threads. Try a longer bolt to see if you have enough left to get a decent bite.. Be careful when using the teflon that you don't have any pieces breaking off in the oil. Then you'll have a bigger mess. Loc-Tite... same thing....
