Because Wade wasn't at the workshop in the morning I dropped in around lunchtime to find him pottering around with Big Red. But I soon left him to it because of this thread - Challenging Mid'30's resto project. Now why would I refer to that? Because, against the advice of a couple of Forum members I was seriously contemplating buying it! I was spurred on by my wife who was concerned I needed a Packard project to play with. Isn't that nice? So I'd teed up a mid afternoon time to inspect the Packard which is located about 70 miles south of Sydney at Mittagong where the Packard National Rally was based in 2009. Only trouble was the inspection time was relatively close to the end time of the eBay auction. I also arranged with my wife that I would phone her to bid, on my behalf after the inspection, should the Packard check out to be worth it. This, as I said, despite advice offered like "...It is a parts car. Period...." and "...You would be crazy to buy this car..." With those thoughts in my mind I made my way to Mittagong where I was met by Al, who I first thought was Rick the eBay seller of the car, after all I'd never met him before. Rick was busy so Al was my guide for the inspection. Followed Al out to the 120 acre property where the car was located and, on driving in, spotted another Packard, a green 20's Sedan with a tarp over the main body. But back to the Packard of my dreams. It's a '3? Packard, a '3?? The more learned and knowledgeable here may have a more definitive answer than '3?, from the pic's I took. Anyway, first look at the '3? was enough to convince me the advice of others was spot on, especially the second quote. Anybody looking to buy plenty of rust was certainly going to get their monies worth but that's about all. Maybe the diff and trans were salvageable but I'm afraid little else was. So I departed, not sadder, but wiser and glad I'd taken the time to check it out. Otherwise there would always be that lingering question of: Should I have bought it? The upside of the trip was seeing some other Packards, there being 3 others visible besides the green '20's sedan. See the few pic's I took, time was limited otherwise I'd still be there. I believe the owner has many, many cars including many, many Packards with those I saw just the tip of the proverbial iceberg.

Wednesday 18th April 2012
Since Monday, when bearing material was found in the sump plug when changing the oil, the engine has been pulled from Big Red and disassembled. On discovering the bearing material, at first, only the sump was pulled to ascertain the extent of any damage. But, after taking off #7, #6, #8 then #1 big end caps and all showed various degrees of damage, the engine had to come out. The big end bearings which failed came from M... and were semi-finished shells which were then machined to fit. Wade isn't happy because the same thing happened previously following the original engine rebuild. Why is it happening? Is it the bearings? Most probably. Is it the machining, balancing and other work? A possibility. Is it the assembly? Not very likely. What other factors could be at play? Thoughts? Opinions? Insights? Anything? Wade is weighing up his options and has been talking to Barry Smith and his engine rebuilder in Tamworth, who rebuilt Barry's V12 with excellent results.

shorthand notes of some thoughts
Quote: ...semi-finished shells which were then machined to fit... Bearing shells consist of different materials that become softer, going from inside to outside, often starting with bronze as a base up to the babbitt (alloy) as the bedding-in layer. The babbitt surface is paper-thin. When disambled after reaching the end of lifecycle the coppercolored bronze of the base often gleams through. Who machined the shells? Quote: ...Is it the assembly? Not very likely... In the knowledge that Wade is a master of his trade and Mal a partner extraordinaire it isn't easy to speculate. How about the axial clearance of the crankshaft and your way of accurat determination? As you know the gauge must be solidly connected to the cylinder crankcase and its tracer should touch the crankshaft edge, the pulley or the flywheel (sorry for making a virtue of the obvious). When moving the crankshaft with some power in axial direction even minor deviations are visible unless the dial gauge is inaccurate. Once I tried to challenge a sprint record with the use of an inaccurate stop watch. Quote: ...Thoughts? Opinions? Insights? Anything?... The play of the crankshaft sliding bearings influences the oil pressure. The smaller the play, the higher is the pressure. Therefore the oil pressure is useable as an indicator for the play of the crankshaft bearings. Did you observed particular divergences in recent months or even right after engine rebuild? Quote: ...What other factors could be at play?... Last but not least the oil quality comes to my mind.

The oil temperature should not be forgotten to mention which may causes a discontinuity or even break down of the film of oil on the inner surface of the shells. To open the attached list of mugshots takes some few seconds.
Wade & Mal, chin up, chest out.

Gerd,
Thanks for your thoughts and the reference material supplied. I'm sure Wade will find them useful in his search for the cause of the bearing failure.

Thank you both Jim and Gerd, I'll make sure Wade is aware of this resource.

Jim, to literally "read" bearing shells seems to be a great work method. I hope that BigKev will agree to include this article in the How-To's & Tech Tips. Future generations will call us the bearing shell whisperers.
