Allergy Test, Part 1

Put oil back into Hanky to see if it would be rejected or have any other adverse reactions. Started right up. Lifters clacking away. Pulled it out of the garage, so as not to fumigate the whole house through the garage door. Let it idle up to temp. Ran it above idle for a bit. Lifters quieted down and it sounds good. It's not puking oil on the ground. So far, so good. It does have a good bit of blow by as seen through the unhooked PCV. And there was oil in the air cleaner and on top of the carb. Not from this run, but from the ride home. So clearly it is blowing oil. But running it tonight, it didn't seem like there was that much crankcase pressure. No sign of water in the oil - yet. Didn't check for bubbles in the radiator. Next step will be to do a compression test to see where we stand.

Why oh why do my friends all develop engine troubles after I scrap my spare engines? D'oh! >.<

Seriously though, what bugs me about this oil blowing symptom is that it is intermittent. Perhaps the PCV is sticking and/or the spark arrester (sp?) is clogged? If you have significant blow-by both these need to be working well to mitigate higher crankcase pressure. Heck, you might even consider putting on two driver's side valve covers so you have a second spark arrester for better breathing.

Just thinking aloud here. Let us know how the compression test turns out. Sure was fun riding along with you at this year's Pinelands. :)
