Valves are out - all the intake valves are super thin and many were very corroded. Quick clean up of all but three to demonstrate the condition of the valves. Seats also cleaned up pretty good. No wonder I had zero compression in several cylinders. Love the Packard logo on the valve heads.

It wasn't cheap, but worth it in my opinion. Let me check my file, and I'll PM you.

The Highlands Motoring Festival continues to get better and better each and every year. While the featured marque this year was PORSCHE, and there were amazing world class Porsches, the prewar cars were also pretty impressive. Duesenbergs, Bentleys, Auburns, an Alfa and one 1927 Packard. If you are nearby Highlands, NC and have never been to the motoring festival, put it on your calendar for 2023- June 8-11, 2023.

Gary- thanks for you input. Yes, I think the slime is due to the copious amounts of WD-40, penetrating oil and Marvel Mystery oil that I poured in each spark plug hole attempting to free the valves. Most of it ended up in the manifold and came pouring out as it was removed! :)

Head is off on 1931 Packard with poor compression

I finally bit the bullet and pulled the head off, after trying to free up stuck valves. Thanks to everyone for their input on my previous thread regarding this issue. Will pull the valves and clean up the valve stems and valve guide passages- may need to grind valves and seats. Hopefully we’ll be able to get compression up to 80-85. Any tips on de- carbonizing while I have the head off? The work is being done by a good friend and master mechanic who rebuilt my Auburn engine a few years back- in good hands. Thanks

Here’s a quick update on my valve and compression situation. Over a period of several weeks, I’ve been squirting generous amounts of penetrating oil, WD-40, Gumout and Marvel Mystery oil around the valves through the spark plug hole. Initially, exhaust valves in cylinders 2,4 and 6 were hanging up. Cylinder 6 valve popped back down with gentle tapping on the valve head through the spark plug hole. Same with the valve in cylinder 2. Number 4 exhaust valve has been stubborn- didn’t budge with vigorous tapping through spark plug hole. Finally after several rounds of lubrication oils it finally released- still hangs up, but with a gentle tap , it pops down. I’m continuing to work it periodically and it is improving. Also, I’m starting to get some compression in cylinder 6.
Here is today’s video of a portion of the valve train in action. The far right valve is troublesome yet improved #4 exhaust valve- starting to show some limited movement and easily springs back in place with gentle tapping. https://youtu.be/hy1mKJDtv20
