Michael something that helps there is to fill the cooling system with just water - a much more efficient heat transfer medium than the typical 50-50 winter mix. Try it you'll be amazed.

My Driving was limited to mostly highway miles, no track time, and very-limited hard driving, certainly nowhere near redline or the limits of the car. But I have had several excursions of very HOT driving, where speeds were low and engine temps were soaring.....

Michael,
What kind of oil were you using? How long between changes? What kind of driving did you usually do? What oil is he recommending for when the car
is back on the road again?

My mechanic, David Feinberg, believes my choice in oil coupled with the heat did some serious damage - the piston rings scoured the cylinder liners, and vice-versa when the oil 'broke-down" from high-heat, and the bearings in the motor are all SHOT. The Cams and Crankshaft were spared, but the bearing sets have risen in price over the years....and so have cylinder liners. I
also burned-through a piston. I also have all of the engine gaskets to
replace (a whole-set of engine gaskets are $1,800, which include the head
gaskets). All 16 exhaust valves are destroyed, along with 9 intake
valves.....the previous valve job managed to 'nick' all of the valves and corrupt their sealing properties, so my compression/leakdown numbers were horrible across the board. I suppose I should be lucky that the Block and Heads were spared, but the internal 'bits' that have been roasted over the
years....crap!

Anywho, we'll have to sit-down and review what the way-ahead looks like.

As Bill famously said, "I feel your pain." In my case a TR first gear
repair, a crown gear carrier upgrade, and a ridiculously expensive
throwout bearing replacement. Kind of like the restaurant price guide
- $$$$$.

Well, the good news is that the Block and Heads are NOT warped at all. In
fact, we can re-use them with only minor machine work.

And that's about the only good news I have......there was evidence of a
previous valve-job done BADLY, and most all of the valves need replacement, along with the valve guides. I also need one new piston, all new piston rings, and here's the kicker - all new nikasil cylinder liners. Ted Rutlands was called, and he has NO QV engines 'on the shelf', so I'm stuck rebuilding
my own engine. The parts bill will be steep....
