My 1963 Ranchero has a 144 stock engine that was supposed to have been "rebuilt". It was running fine but the rear main and trans rear seal were leaking so I pulled the trans and oil pan. While scraping the pan rail I noticed the timing chain had 1.5" of play so I pulled the engine. since I have a lift I just dropped the engine from the bottom, easy. The dist is new and all the main/rod brgs looked good. New timing chain/gears. Making sure the timing dots were aligned.
I put it all back together, repainted it. How easy.
when I went to start it, it did run fairly smooth but then started making some loud metal banging like a stuck valve or collapsed lifter (like a valve or 2 was slamming shut). I shut it off, pulled the valve cover and plugs and did a compression check. Results:. 105,130,140,130,130,120 and I'm not happy so I did it again wet, no change. All the plugs had a bit of oil on the as well as the pistons I could see thru the plug hole. I verified the pistons where coming to TDC in firing order and valves were opening and closing. but a couple were real tight and a couple were real loose. I adjusted those at TDC to zero lash since I believe this engine has Hyd lifters. I put it all back together.
Setting the timing was a chore since the engine would barely idle and would not rev-up. I verified the firing order and number one but still will not run and there isn't a noticeable miss. The timing mark is way retarded and I cannot get it advanced.
I am trying not to have to pull the engine again. Can the lifters be collapsed enough to do that. This is like bam, it won't idle or accelerate. Oh and the carb is getting plenty of gas. the dist does not have mech adv only vacuum (Load-O-Matic dist) from the 1100 Autolite.
I've been looking at this crazy issue for so long my brain is fuzzy. It just doesn't make sense.
Can anyone help.
