engine oil leak 2gm20f

Last time we checked on our hero, he was patiently waiting for engine parts, whiling away the days with varnishing projects.

Well, the parts finally arrived and I reassembled the engine and reinstalled it. Then (of course) corrected my errors in hooking up the various wires, cables, hoses – then it ran! After my first test run, the prop shaft began to back out of the coupling as I backed into the slip, and I nearly lost it again – but it hung up in the shaft log, and Ruth and I managed to fit it back into the coupling. Yes, the set screw was installed, but I’d done it incorrectly. Turns out, you have to “spot” the shaft. That is, drill an indentation in the shaft into which the set screw “sets.” I did that (easier to write than to do – involved long, sweaty minutes bent over the top of the engine with a drill, boring a divot into the shaft), then reinstalled the set screw with thread lock. It’s been fine since I did that.

Next thing, the engine ran away. You read that correctly. . . diesel engines can scavenge fuel from places other than the fuel injectors, and run without regard to the throttle position or stop lever. But why and where? Much reading ensued, afterwhich I concluded that my engine’s symptoms matched those which indicate that the fuel lift pump was leaking, thereby dumping fuel into the crank case, thinning the oil, which was then burnt in the cylinders. The run-away only lasted seconds before all the excess combustibles were gone, and so no damage occurred. I ordered another pump and installed it. Problem solved, but a scary experience.

Family commitments intervened as well, and then we got to go sailing for the first time this year. In July. We over-nighted late last week, crossing the bay, up Harris Creek ’til we got to “Drew’s Cove.” It was stunning, deserted, perfect. Here are a couple of photos to prove it (Ruth gets the photo credits this time).
