I lived 45 of my years on Cape Cod, mid-state NH and Maine, and never had such build-ups--then again I also never allow an engine to idle for long periods when cold, and never unless completely unavoidable make short trips that do not allow the engine to come up to full operating temperature--both just about the worst things you can do to an engine.

Just things my father and grandfather taught me to do...

After networking to a retired Dearborn proving grounds wrench who called an active dealer wrench, among others, lacking a milkshake they say the road is waiting. And yes, they both have seen the slime but not in the amounts I see. They can't explain how on a 50 degree sunny day I can go 5 miles at a high rate of fuel consumption and have white slime on the filler cap. They agree there is too much moisture in the engine. I've checked the obvious things like the PCV, hoses, from above and below.

Only thing makes sense to me is looking at the cam thru the oil tube which slings oil at high temp, cooling on the plastic cap. Was there supposed to be a deflector to prevent this that is not there? I examined the old oil drained yesterday and it's clear.

So I put a couple tablets of Bars leak, 1/3 of recommended dose (for which I was scolded by the Ford purists) to diminish the chances of being found on the side of I-75.

The deceased new car purchaser did a few things to it, sub frame connectors, AND Hypertech programing. He's got it shifting at 6500 and what else I don't know. It runs so well I don't want to start changing anything, but I can't imagine how that could create this problem? Car has ZERO blowby at 87K.

Thanks for the help!

Im just suprised people haven't seen this more often, when i worked in the ship 9 out of 10 cars that came in had the buildup

My experience with this it is always the cars that are not brought up to operating temperature to burn off the excess moisture in the engine. None of my cars have it because they take no short trips. Analyze your driving trips before you go calling every retired Ford engineer to fix a problem

As a forklift tech in Nebraska I see this a lot. Talk about abused engines. Its most prevalent in machines that sit outside and are used infrequently, and / or are not allowed to reach operating temp most of the time. Usually see this crop up this time of year when the temps swing wildly as well.
