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.

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.

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.

 

Phil

what about using rifle bore cleaning brushes ?

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'.

Bought some tube and fittings and reconnected the oil pressure line. Need to get some P clips.

Now all my gauges work properly.

I do rather enjoy looking at the gauges. 

 

I ran the car up to warm and the temperature gauge was pointing to about 210- I got worried and checked the temperature of the head, thermostat housing, radiator with my handheld infrared thermometer, the hottest part was the thermostat housing at 175F, the temperature sender was about 165. I then remembered I calibrated the gauge at 12.0 Volts- with the engine running a stable 14.4 was making it over read and with the engine off it was reading somewhere correct, so I think it has a voltage regulator in it's future to be useful.

 

Other than that I'm fighting with the vacuum system for the wipers and particularly the screenwash bottle, which refuses to pump given the volume flow through the wiper motor valve.

Not a great deal to report right now, but I'm going to see about sending the wiper motor off for rebuild.

Front driver's side brake adjuster locknut cane off without too much of a fight.

 

20200130_165423.thumb.jpg.25a56964cddab326959fc45e32ab0cc2.jpg

Cleaned it up.

 

20200130_165655.thumb.jpg.035b3dc27c487bc61f75b18a8d8f28eb.jpg

...and painted it black. Drum off next, bearings will get a clean and fresh grease, I will free up and lubricate the lower adjuster then reassemble it all and set the brakes.

Previous keeper overpacked the hub with grease. A small amount got into the drum and onto the edge of the brake shoes. Thoroughly degreased the hub and drum, rubbed the outside down and gave it a coat of paint.

 

Shoes next up to be thoroughly cleaned.

As much as it's nice to have a fairly comprehensive set of gauges in the dash, I do like having a couple of attention-getters for important things, particularly as the oil pressure gauge is rather lethargic.

So, I fabricated a little under-dash light board that's fairly inconspicuous.

 

20200213_173156.thumb.jpg.b4a228a33f4573bfb319fe7d7078e165.jpg

Heat stamped the meaning of each light (changed the colors around because the orange is more visible and the oil pressure concerns me much more than the charging system) so that's good for now. 

Decided to just shotgun the brake cylinders so that's on hold while I save up for the parts, hence doing stuff that costs nothing because I had the parts to hand.
