TR6 I'm Driving a 75 TR6 from Denver to the midwest.

Not enough to worry about, IMO. I drove from LA to Breckenridge, CO and while I tried touching up the mixture several times, it didn't really make any difference. And it ran fine all the way home.

Forgot to mention, I've only got 5 cylinders to work with
 
Mixture adjustment may be slight, but once you get home you may be able to back the timing off a degree or two. We tend to run a wee bit more advance at altitude.
 
Um, is the engine damage repair cheaper than towing it?

Won't the unburnt gas wash down the cylinder walls and over that long of a time potentially impact the oiling on the overall engine?
 
I drive between 2000 & 7000' more or less daily -- no big deal, certainly wouldn't be adjusting every time.

As for the dead cylinder -- would it be prudent to back off the intake valve adjustment so that valve never opens? Really have no idea but do see the the concern about fuel washing down the cylinder.

Not likely, IMO. Once the engine is warmed up, the fuel should stay mixed with the air, and simply get pushed out the exhaust valve when it opens. And any fuel that does make it past the rings will quickly get boiled off from the hot oil.

But rather than waste all that fuel, I'd take out both pushrods.

My first car was an in-line 6 with one dead cylinder. Not exactly pleasant to drive, but it ran surprisingly well that way. Worth every penny of the $15 I paid for it :smile:
 
Randall,

He actually did take the pushrods out before hitting the road. It took all of about 10 minutes to do. I'm the one who sold him the car. The car runs amazingly well on 5 cylinders. He shouldn't have any problems at all during the trip. It wasn't easy saying goodbye to the car but it now belongs to someone who will take very good care of it. Other than the needed motor work the car is practically a perfect specimen of a totally stock 1975 TR-6.

Who knows, maybe there's another one in my future. Or maybe a Spitfire. I owned a Spitfire back in the late 1970s/early 1980's. It wasn't a TR-6 but it was still a great fun car to drive.
