It's probably time I begin to admit my age... But 'Geraldine' shows me no mercy. We're gonna have to have a good sit-down talk before I put her back together.

Rule out damage or spun bearing as your oil pressure is good.......
You need to run lash on that cylinder #3......
Did you inspect the spark plug close to see if the ceramic is cracked? A cracked ceramic is tough to see and will zap through it to the manifold...the resulting zap sounds much like a tick.
Start the engine in a dark room with the hood open and look for lightning/fireworks zapping from anywhere in the ignition......
Do a leak down on this cylinder.......this will qualify if this is piston/valves/rings.....
My mechanic is a one-man-band so I'm in his hands. I know he has a shop full so as anxious as I am to see what the issue is, I can't pester him
That I completely understand. Our C3 went “under the knife” (the mechanical knife) 14 weeks ago. He too, is a one man show. The wait will be well worth it!
I’ll have to post a thread when all is done. We have well over 200 photos and videos documented the work being done.

Thanks, that's a bit more reassuring. Ernie's coming over tomorrow evening so all should be clear soon

Ernie's looked after all my Corvettes and he's getting up there in years. Shame he has three daughters so when he calls it a day, that all she wrote.
A few months back I received an unsolicited email and it turns out to be a fellow Brit that had imported a '72 LT-1 which has running / carb issues. He tried in vain to find someone to work on it down south so next week he's trailering his Corvette up to Ernie to be fettled. Good reliable mechanics for these 'older' cars are hard to come by over here. I'll look out for your thread with interest when you post

Sounds like the perfect opportunity for you and the other guy to spend with Ernie learning everything you can from him.

Definitely.
Last year when Ernie had a similar back log to that he has now I offered to spend a week in his garage without pay to help him out but mainly to see what I could learn. I don't think the idea of a then 53 year old lacky thrilled him too much so with a withering look and no words spoken, that idea died right there..
I can do most things but engine internals are best left to the experts in my mind with my limited experience but seeing how he goes about it later should be interesting.
Having rescued this one from a barn earlier this year I did everything except fit the replacement 4bbl Holley and change the fuel lines from pump to carb. Over the Winter I'll be replacing all shocks and suspension bushes

I get that he didnt want a "lackey" around the shop slowing him down while he earns a living.. i was more thinking about in your garage, his garage, a bar, type talk.

Yeah I get that!
He's due in an hour so fingers now crossed. Red is booked in for a big meet at a fantastic castle venue on Sunday.
Seeing that pic I posted again I realise that was quite early on into the works on the yellow one. All the chrome came off for chroming and then was aligned better when I put it all back and I media blasted the rally's that were painted BLACK! I did get it out this week while red takes an enforced rest..
Enjoying the FA (failure analysis) and the banter. As some have posted, I agree, finding a good mechanic is getting hard to do. My grandfather (1909 - 1990) owned a garage for 40 years. One time I was having trouble getting my car started ('76 Buick Century) after the engine compartment got packed with snow during a driving blizzard (can anyone say Buffalo, NY). It started once, ran a few minutes, then quit when the remaining snow started to melt. I dried everything as best I could even going so far as to pull the distributor cap. Cranked it over an nothing. Checked plugs and no spark. Two days later I'm still trying to figure it. Finally call Gramps and he asks "Did you pull your distributor cap?". I say "yes". He says, "did you pull the connector off the back?" I say "yes". He says, "Check the contact on the distributor cap that connects to the red wire. A lot of times when you plug the connector back in that one gets pushed up instead of mating." Sure enough that was it.

Exactly!
Ernie didn't let me down arriving around 7pm after a full week of garage working in blistering heat this week. Arrived in style in a '56 Pontiac which he has just rebuilt the gearbox for a customer.
So it's not very dramatic thankfully as within a few minutes he'd diagnosed a cam lobe failure on E3 and the E3 rocker was loose so on start up it cracked as it came down with so much play. We disconnected the coil and cranked it and E3 had maybe 30% movement. Gapped & tightened it then cranked and zilch. Coil had failed (12 months old) fortunately I had one on the shelf that worked so we fitted that and put it back together. So I'll research cam specs for the LT-1 but IT should be fine to use in the meantime.
The iron bits from Both the failed lobe and its lifter are circulating throughout your motor.
I suggest you do Not continue operating it until you have thoroughly flushed motor and replaced cam, lifters and whatever else has been scarred by all those iron bits.
Otherwise, plan for a complete overhaul; sooner rather than later.
Its too late on trying to save metal from oil circulation. Cam lobes don't wipe over night, nor in a few weeks or months. It could take a year to wipe a cam lobe depending on engine activity and / or condition of oil.

Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
I did, LOL.
