Oil leaking at exhaust manifold?

[tco3129]

Replaced my busted block engine with a running engine from a parts truck. First I noticed a ticking sound and assume the rockers need adjusting. Puzzleing to me is oil ozing out around the #1 and #6 cylinder exhaust manifold. It's not the valve covers - they're dry. Bad valve guides? Injectors sticking and flooding cylinders with fuel? I got no idea but my mechanic buddy says local driving only till we find out why. (Cheaper tow bill) Anybody got any suggestions??

A ticking sound sometimes indicates a head gasket fire ring compression leak, it will ooz fuel and look like oil if your running wmo as fuel.
It happened to mine.

It sounds like what they call wet stacking it is cause by not fully burning the fuel from the injectors. The knock could also be the tip washed out of the injector where it is wet stacking if running the over head does not take care of the knock. If no problems with the parts and your engine gets up to operating temp the best way to not wet stack is to drive and NOT let it idle much.

Planned to pull the injectors just for a look see. Don't know if these injectors are one hole or two. My old engine had two hole. Don't know if it really makes much difference.I had hoped not to pull the heads. After buying the parts truck, a clutch kit, transmission jack, chain block, and gantry crane, I'm about tapped out.

Just read "oil from exhaust manifold" from the similar threads column below. Sounds very promising. -Don't idle it, run it.- Sound plausable to you guys?

The two hole injectors are a newer style, when you pull them,have them pop tested,that's the only way to tell if their working properly.

Can you mix and match 1 and 2 holers

It would be better if they all match in pressure test and style.

If you think one or two might be bad, put a screw driver handle to your ear, then put the tip on the injector body while the motor is running. You should be able to hear the difference of a bad injector.

Edit, if you have another set of injectors, have them serviced! Then swap out that set for the set in your truck.

One or two hole doesn't matter, as long as they all match. You might try adjusting the valves first. Bad valve adjustment can cause unburnt fuel to accumulate in the manifold runners quickly, which mixes with dry carbon and then leaks out looking like oil. Bad valve adjustment also can add to oil consumption and really bad fuel economy.

Thanks everyone. Swapped out #1 & 6 injectors with known good. (all 2 hole) I'll get a full set tested and swap in all 6 when the $ is available. Also adjust the valve lash next day it's not raining. It now seems to run pretty good. Made 2 trips to town, about a 40 mile round trip each. Leak seems to have stopped or at least slowed. Again, thanks much guys.
