Drained the oil and dropped the lower pan on Port engine to replace a leaky gasket. Now looking like it was the upper pan where meets block or front cover draining down onto a pan bolt. Either way, now's a chance to inspect the internals after first 100 hours on it.

Wife took up Yoga a couple years back and bought this nice $40 Peloton mat that she never used. So told her I was going to give Yoga a try.. Hell with Yoga, and the mat sucks too.. Switching back to cardboard..

Found half of the oil level sensor laying in the pan. Couldn't take the shakes.. Glad I never connected those. Pickup looks clean, all the bolts still in the baffle. So far so good.

Think I'll run a scope up the bores and pistons to see how they look from bottom, but beside the Callies throws looking a little dull, no hot spots jumping out at me..
Ya guys think I should polish the crank? Certainly deserves it... 1 BAD MOFO 🤪

I keep trying to increase the stroke. Guessing it takes more than 6,000R's to make those rods stretch very much..

At PRI, the Callies crew said zero failures reported on the Ultra B's. Then 10 minutes later Jeremy told me that one broke, as he's was leaning on a stroked Winburg unit.. My money is on these right here as the undisputed heavyweight camp of the bottom ends.. Counting the FD balancer, and 84lbs of flywheel, there is close to 240lbs rotating mass, spinning 6k, and the smoothest engine ya likely every feel when all wound up.

And I forgot. No Girdle.... :unsure:

Pan gaskets and set of valve cover gaskets arrived today. I purposely switched back to the cork for the lower pans, med-duty units. But these new lower valve cover gaskets got me scratching my head.

Always used OEM steel. And reused again and again. Probably 4 or 5 times the covers been off on that engine. Never leaked a drop.

So what's the word on these compression gaskets? Worth a try, or send em back?

I hate cleaning graphite, I'd throw them away on sheer principle :ROFLMAO: I do love using some Hylomar on cork.

Although some techs and myself experimented with spraying graphite head gaskets with wd40 for easier cleanup, that was a short term use as we were tearing the cylinder head off about every other day

I'm just shocked you were able to reuse the stock gaskets 5 times without any leaks. I've never even been lucky enough to reuse them once without a leak.

I've always used the steel OEM type from Mahle or GM. My only experiences with the graphite compression gaskets is they're a pain to deal with.

I spray all my metal gaskets (think valve covers, exhaust manifold, up-pipe, coolant crossover, head gasket etc) with Permatex copper spray gasket. I've done this my entire life as that's what father taught me and to this day (knock on wood) I've yet to have any form of a leak.
