Valve tool ahoy. Compressed the valve, removed the collets and then started to fight with the valve.

This took 40 minutes to remove from the guide. It was just dirty. Cleaned the guide and stem up, oiled up and it drops in happily now.

Spent a little time lapping in the seat. Not the easiest position...

That one doesn't seal because the head is bent...

 

I am going to need a couple new valves, I think. Going to pull the rest and inspect them, being as there's no mechanical signs on this one of being bent, I'm thinking perhaps it was either made wrong or wasn't heat treated or is the wrong metal mix or something.

I don't know any local machine shop that would do that- there really aren't many places left around here who aren't just parts fitters.

Phil, give a call to Terrill Machine (two-five-four) 893-261zero. He was able to supply me every part for my straight eight rebuild, valves included. The parts are the same as or better quality than the others and his prices can not be beat. He’s fair on shipping, close by, and a gentleman to boot.

Thanks for that - I want to get the rest of the valves out first and inspect them and the guides before making any calls. It's been cold and I've not felt like crawling around under the car - plus to do it without losing the collets is a two-person job because I can't reach to give the valve head a tap once the spring tension is taken up and the valve stem is supported...

 

Hopefully this weekend I can make some progress.

I’m pretty sure your block is the same as mine, be careful of the holes in the bottom of the valve gallery. I plugged them with something so the collets wouldn’t fall through. If you’re worried, a good magnet placed next to the bottom of the valve stem will catch the collets.

That had crossed my mind. You can see the rag stuffed in the drain hole by the valve missing the spring- I also had Magnet-On-A-Stick (very useful tool) sitting in the gallery which was used to pluck the collets!

 

Putting them back on is better, a bit of grease on the inside of the collet and it sticks to the stem and stays there.

Started pulling valves out. Everything needed a good clean- that there is post clean.

All but one of the valves removed so far are good. Still don't know cause but replacing it will help.

 

Gotta rotate the crank round and get the last 4 out.

Block looks pretty barren now. Seats look good though.

Valves all clean, but I'm thinking about getting an ultrasonic bath, doing springs and stuff in gasoline with a brass brush is horrible.

I made a guide brush by chopping up a toothbrush and gluing it to a piece of dowel. The glue is setting right now, I'll see if it works tomorrow.

what about using rifle bore cleaning brushes ?

I had considered that but I had this to hand and figured it is only going to be ruined in the process so why spend anything on destroying a tool.

The brush proved effective, flushing through the guides with brake cleaner and oiling them up with clean oil afterwards. Starting to lap the valves in, ran out of time tonight but hopefully I can finish up 15 this weekend.

Going to call that done, I think. 

 

Regular scheduled programming will resume soon.

I set about cleaning the valve spring components, oiled them back up.

Brand new exhaust valve arrived in from California Pontiac Restoration. I lapped it in to the seat and it sits nicely now.

Had a little time yesterday to work on the car so managed to fit the springs to the intake and exhaust of #1 cylinder, and set the clearances to 13 thou'.
