Guest CharlesinMaine Posted October 25, 2006 Share Posted October 25, 2006 1953 331 engine purrs with exception of one intake valve hydraulic lifter. When running and I push in non-operating lifter push rod that is 1" short of reaching rocker, there is still no recip motion. Must I assume a blown cam lobe? I would think I would have direct mechanical connection with lobe with pressure on push rod. I guess next will be to pull intake manifold and examine lifters. Any advice would be much appreciated.Charles In Maine Link to comment Share on other sites More sharing options...
hchris Posted October 26, 2006 Share Posted October 26, 2006 If I`ve got this right you have a pushrod that is 1" short of the rocker arm ?I would`nt be running the engine without further investigation, something missing somewhere & if so its`probably in the sump, could be you have also bent a pushrod which begs the question as to why313royal Link to comment Share on other sites More sharing options...
Rusty_OToole Posted October 26, 2006 Share Posted October 26, 2006 Something is seriously wrong. You will need to investigate. At least take off the intake and valley cover.If your engine is an early 53 it may have the early style lifter with a removable insert. Late 53 up uses a modern type lifter.A 1" gap is too much to be a worn cam. Link to comment Share on other sites More sharing options...
Guest CharlesinMaine Posted October 26, 2006 Share Posted October 26, 2006 Thanks for input, pulling intake manifold and valley cover to examine lifters etc.. is there any way to view cam lobe without pulling cam?ThanksCharles Link to comment Share on other sites More sharing options...
Rusty_OToole Posted October 26, 2006 Share Posted October 26, 2006 With the valley cover off you can easily see the lifters. There is a row of oval holes, you can look down at the cam plus you can pull the lifter out to check the cam lobe. Link to comment Share on other sites More sharing options...
Guest CharlesinMaine Posted October 26, 2006 Share Posted October 26, 2006 Rusty:Thanks for all of your guidance. The in op newer style hydraulic lifter was mission its spring clip and cap while allowing the push rod end to travel down to its inner plunger spring in addition to being stuck in the extended position and having 1/4" of its tappet body broken off by prior attempts to extract. I extracted the body with an easy out and penetrating oil.Where can I buy these newer integral tappets?Your help is much appreciated.Charles Link to comment Share on other sites More sharing options...
