Oil Leak. Im confused. Please Assist.

[zackadams10]

Hello fellow steel soldiers,

I am dealing with many problems right now on my lovely M1009, but I felt the best way to tackle them before winter is one by one. However, I understand mostly how to fix them all except one of them, The oil leak. There is a slight oil leak coming from the 6th Cylinder, right above the exhaust manifold. Unfortunately its not the valve cover like I had hoped. So I am wondering what you guys here have to say. Have you dealt with this problem before? Where is this mysterious oil coming from?

Any help would be appreciated, I can load pictures if necessary.

First guess would be fuel leak from return line or injector line. Mixed with engine dirt, a fuel leak can sort of look like oil.

Check the CDR as well. Might be dripping down.

I have similiar on #8 cylinder. Its very minor, not enough to drip on the ground. Been like that for years.

Like the others said, I'll bet it's an injector return line. . .

Well... I can tell you in my case it certainly isn't the injector return line.

some times an engine will what they call wet stack. that means the valve in that cylinder may have issues letting unburned fuel push out the exhaust valve i have seen this on a bigger engines. im just throwing this out because there i have seen it, that dont meen thats your problem
