Agreed. In gas engines heat does more to change color than anything else. Low speed driving likely never gets the oil up to temperature.

Eventually the plugs become “One with the head” if not removed/replaced. I would never leave originals in for more than 50k before removing and maybe putting them back in with some anti seize on the threads. Also

My Cessna Centurion C210E had an IO520 Continental engine, 285hp. Largest land bound engine was the 283 bored to 292 in my ‘59 Chevy truck.

Noise on startup that goes away might be piston slap. Which is much better than a rod knock.

What sort of engineer? Because I doubt he was an ME.

Just check it at the battery. If the battery is defective or dead the voltage can drop nearly to zero.

It may take a second set of hands but you really need to check voltage while the key is in the start position. Or at least try jump starting from a known good battery.

I hope your experience is as good as mine. Had mine done last December. Couldn’t take the Oxy (Crashed my BP!) so the first 2 weeks were absolute Hell. But once I got going with PT it has all been great. I have about 130 degrees bend but still can’t quite straighten it. 6 months Doctor...

Their 75W/90 MTL (Manual Transmission Lubricant) is the best for most manual transmissions. Shifts like butter.

I hate it when someone runs into my lower unit. Except if she is cute.

I told my Mother several times that the best thing I ever did for her was marry my wife.

Synthetic resists burning to a considerably higher temperature than conventional. Even in a piston engine a fair amount of oil gets past the rings. Synthetic not burning actually means must of it stays on the cylinder wall and makes its way back to the crankcase. Back in the’80s my commute...

If you are certain it is reasonably clean use whatever appeals to you. If there is a possibility that it is sludged up, why not try Valvoline Restore and Protect?

They should restamp the 240Z with a fresh motor that passes current smog. They could sell a million of them.
