The 340 is out....again.....
Oil pressure was always consistently good, so its' possible the two conditions can coexist; having the pickup rub/scrape and still have normal pressure within the oiling system.
It was drawing oil, just not the amount it should have. I'm wide open to suggestions as to what other condition would have caused the camshaft to destroy the bearings upon which it was supposed to rotate on a lubricated surface. Of course, at this point it's moot because I don't have any "proof" the previous shop screwed the pooch on their rebuild which I could use to go after them for any kind of compensation. Just one of those Ownership of an Old Car Things, I suppose.
On a different note, I had a new XV Motorsports lower radiator brace installed by the shop yesterday (Saturday Oct. 29th) while the engine was still out, so I'll probably stop by tomorrow to see how that looks. Sounded like a good idea, as it replaced the sheet metal original and should stiffen up the front end a bit. I'll post some photos when I get them.
Always good to swap ideas and learn from you all, Gentlemen.
