Re: Head is off on 1931 Packard with poor compression

Given the motor isn't seized I doubt the block is cracked. One of Paul Lamb's cars had a cracked valve seat and it was seized up solid.

Some of those valves have the stellite treatment that Turnquist used to sell. The rusty ones probably were sandblasted rather than cleaned on a wire wheel. Not good. I've never worked on a Nethercutt car so I have no idea what the priorities were. I've worked on Harrah cars and was not impressed.

Given the top is off, might as well drop the pan and Plastigauge the rods. Those cars will run without trouble given 45-50 cruising. Beat on them and you better add a higher speed axle ratio and use the Low gear for starting. Hopefully it has the correct trans in it. Turnquist did that with his 840 roadster and it never wore out.
