Hi Guys, I have a 2007 C9 which started to run rough at idle. Was hoping it would be a simple HEUI Injector problem as low engine oil seemed to indicate that. Oil level was found to be quite low on dipstick (probably down 10L). I dipped the fuel tank and the diesel seemed quite brown, I figured oil is transfering into the fuel via the cylinder head. There are no signs that oil is being emitted from the exhaust.
However removal of the valve cover revealed that Cyl. #4 has a pushrod which is stationary. This engine only has 435 hours on it!
I have video taped this while running:
Can the camshaft be slid out the rear of the block once the push rods are removed? Is this a tear the entire engine down situation or a common failure which can be repaired in situ with a new camshaft/pushrod etc? Of course the unit is located outside in the rain and I would have to hire a crane to load the unit onto a flat deck. Big $$$.
Just looking for any input & advice. I am not a heavy duty mechanic by trade but can handle most any wrenching task. This may be a repair I can handle given some print instructions to follow (and the guys at Finning are pretty good at providing these details), but I would also have no hesitations calling in the pros if this is a big job.
