pflaming Posted June 4, 2017 Report Posted June 4, 2017 Aside from high quality mechanical attention, how important is a test of the valve springs tension? Quote
Flatie46 Posted June 4, 2017 Report Posted June 4, 2017 Valve springs can get soft and weak after millions heat cycles, You may have valve float in the upper RPM's. You really want that valve exactly where it should be at every moment of the cycle. If I was going to at least lap the valves I would check the springs. That's just my opinion. It can be yours if you like. 1 Quote

knuckleharley Posted June 4, 2017 Report Posted June 4, 2017 Not as important as if you were building a 400+ HP engine with a high lift cam,but still pretty important if you want your engine to perform as it should. It's a lot cheaper to buy new valve springs if they are needed while the engine is apart than it is to possibly replace burnt valves sooner than expected,and buy more gas than you would have bought if your engine were operating at peak efficiency. One factoid we all have to live with is mechanical stuff wears out,and worn mechanical parts make your car less efficient and more expensive to operate. Putting worn beyond specs mechanical parts back into an engine you have already pulled makes no sense at all because you will have to go back into it sooner to make repairs,and the additional labor alone is more expensive than it would have been to have replaced them while the engine was already apart. Test them,and if they are up to spec,reuse them. If they aren't up to spec,now is the time to replace them.. Chances are you can buy new valve springs cheaper than you could buy the new head gasket you would need to replace them later,plus save yourself all that time and work. 2 Quote

Plymouthy Adams Posted June 4, 2017 Report Posted June 4, 2017 you stated this would be finished three weeks ago...... Quote
DJ194950 Posted June 4, 2017 Report Posted June 4, 2017 Priorities first- Vacation or spend money and time on a motor rebuild! Check spring tensions? Sounds expensive! I'm frugal! Sorry Paul, I promised to be nice to you. DJ Quote

pflaming Posted June 5, 2017 Author Report Posted June 5, 2017 Since I started this thread and I have the answer, I'll stay off topic with this. It is my understanding that clear coat is paint without color pigment. I will totally resand my truck cab, bed etc., and remove, disassemble, clean, sand and then clear coat the parts of the doghouse, the cab, and the bed. That accomplished this truck will be a repainted truck, fully protected. "Each to his own" it has been said many times on this forum. Quote
Plymouthy Adams Posted June 5, 2017 Report Posted June 5, 2017 that is all well and good but how long ago was the fire and it has not been disassembled and these burnt joints cleaned and protected.....man and man made objects are only on this earth for a short time... Quote
pflaming Posted June 5, 2017 Author Report Posted June 5, 2017 Well, it took 65 years outside to get where it is, so I guess stored in a shop since I've had it will significantly slow the aging process. I'm much more concerned about my aging. 1 Quote

pflaming Posted June 6, 2017 Author Report Posted June 6, 2017 (edited) After a thorough steam clean, new distribution tube, top of block squared, valve seats professionally milled, it cleaned up really nice. Now has 40+ ,oil pressure and 110 to 125 cylinder compression. Takes some work, but it's well worth the effort. DodgeB4ya, below, yes that was a pre valve adjustment photo. But, good eye!

Dodgeb4ya Posted June 6, 2017 Report Posted June 6, 2017 Ya got a some big valve clearance there. Quote
