Still lookin'. It does not appear to be on the passenger side which was my best guess. Next week I'll inspect the Drivers side.

@steven-cavagnolo Steve, The longer stems or lifted rocker assembly will not affect spring pressure. The spring pressure is determined by the location of the valve spring "keeper" or "key" in Chevy speak. If the installed height of the springs is correct, (You could make this comparison to your extr...

Created the topic 29 Chevy Rear Axle Shaft Removal in Technical - Mechanical
Put in 8 hours on the Landau today and made a ton of progress. I did find that the threads on one of the rear axle shafts is all buggered (probably why pap always said never to take that wheel off).
Does anyone know of a video on how to remove the axle shaft, or can anyone give a narrative?
Hop...

I took the truck in for tire rotation and the tire warning light went out. Had them check and they could not find any issues so no replacement was made. I am guessing it will act up again when I am prepping/or on a long trip.

@steven-cavagnolo Always good to know the major parts are correct. Nice that you have a correct head you can recondition and swap out and still have a decent spare when done.

Steve, Thanks for the comment. The head is correct as it has the right casting number. I suspect the rebuilder used new valves which had longer stems than the originals, requiring the washers. At this point I don't know how that would effect the engine's performance. I am prepared to have my do...

@steven-cavagnolo sounds like a mismatch of parts. In my opinion it would be best to determine if you have the correct head or if the wrong valves were installed. Trying to figure out what the machine shop did might be impossible but repairing to the correct configuration (original or updated) shoul...

Well, First thing I did was measure the valve stems on both engines. My engine's stems were about 1/4 inch longer that the donor engine, thus the reason for the washers under the pillars. It occurred to me that the higher the rocker arm assembly, the less tension on the springs. That, in additio...

Sad. Can you post a note to that site and let them know the VCCA would welcome them?
Thanks, Dean

Created the topic Old GMC web site in General Discussion
Saw on the Old GMC website that they are calling quits at the end of the year. At one time it was the place to go get reliable information on all things GMC and also Chevrolet trucks. Same thing that is beleaguering this website, rising costs and low member participation, had taken its toll. I perso...

The results of a compression test should help you decide the condition of the valves and seats. If possible, I’d also observe the needle on a vacuum gauge before any disassembly. With regard to recommending whether to use lifter springs, or changing to 216 springs only, I can only say I’ve been hap...

The only time I have heard of putting washers under the stands is if a replacement head that is thinner is used. Might be a good idea to check the head casting number.

Mike, thanks for your reply. Yes, my rebuilder was an older cuss who probably thought cutting corners was OK. I have other stories about him that should have raised red flags, but that's water under the bridge. I guess you could say that I have learned a lot from his mistakes.
The lower sprin...

@steven-cavagnolo Steve, WOW, Washers under your rocker arm shaft supports. What the heck is going on there? You say the rebuilder is no longer available. Was he murdered by a disgruntled customer. Is he in prison for impersonating an engine rebuilder?
The only reason I can think of for washers in...

Minetto,
Thank you for your reply, Would you recommend getting the later model springs over using the lifter springs that I have from my second engine?
I think I will do a compression test before I proceed to see if the valves are OK.
I have new motor mounts in place.

Steve, The 207 engine in my 34 Master ran poorly when i first acquired it. The combination of observing a vacuum gauge, and performing a leak down test, caused me to remove the head to check the condition of the valves. I found that the exhaust valves were burned and sure enough, the lifter springs...

My tale of woe continues. I have driven this car around town without too many problems, however recently I took it on the freeway and found that at about 35 mph the engine started vibrating and there appeared to be a relative loss of power. In the garage I found that at about 1700 rpms the engine ...
