Hey guys, I got troubles. I have creamed oil in the rocker area on the right cylinder head. The front two lifter rods are coated with it. It is also all over the upper portion of the distributor shaft. none shows on the dipstick. The dipstick oil looks normal.
As I started tearing down, I found water in the exhaust ports of the heat exchanger. I haven't figured out where it came from yet.
I have three main questions;
1. Thoughts on how water could get in the exhaust ports. And what do I do about it.
2. How do I adjust these valves? I have the book. The book (clymer, mercruiser)says adjustment is not necessary on a Gen II engine.
I don't think I have a Gen II engine. My rockers have studs, with nuts to hold them on. The nuts spin freely until they are tightened. Which makes no sense.
3. How can I rotate this engine manually? with that itty bitty bolt on the crankshaft?
thanks in advance,
If you would rather have pics, let me know.I can have them on here in 5 min."
