I'm sure you'll know what the following numbers mean. I was going to rebuild the head this winter anyway and am pulling it off. I did a compression check before pulling stuff off and can see why I had a bit of a 'miss' coming back from the restaurant a few weeks back.
Winter means spending some time with wrenches.
Here's Bob's first in a series of technical quizzes.
What do these numbers mean?
...and more importantly, what do they mean?
6 5 4 3 2 1
115 140 135 150 150 25(!)
Answer on Wednesday at the November dinner.

Probably a bad valve....if you squirt oil in the cylinder and the compression gets better it is rings. It would certainly explain your recent increase in oil consumption.....off with its head!!
Let me know if you need some help.

looks like cyl 1 has a bad valve, cyl six is also low, try and borrow a borescope and have a look down into the cylinder and have a look at the valves.as Joe says of with the head//////////////// Rob H
Head's coming off. I had the spare at Ian's last week and learned quite a bit from him. The spare has problems so I'm going to do mine. For a change, I'm starting stuff NOW rather than procrastinate till a week before driving season.
Joe, make sure you check out the link to the Brit Jag-lovers site. There's about a billion detail pictures of original E-Types.

stuck valve on # one due to sucking up an eagle or porcepine thru the intake manifold and compromised head gasket near 4, 5, 6 due to poor cooling near the rear of the Jag block. (come on guys it's a Jag it can never be the obvious) Pull the engine and drop in a 350 Chevy crate engine and problem solved at 1/3 the cost :)
