Started my 63 F-250 4x4, w/292 over the weekend, new plugs/wires/cap/rotor/points and condensor, have spark to all cyl, but it is missing on #'s 1,2 and 7, pull the plug wires, no change in the engine, plugs look shiny oily. Did I bend some pushrods, it hasn't runs for not sure of how many years, was registered non-op in 93,,,, I have valve cover gaskets on order, any other things to look for?!

 

take off your covers and check your pushrods as you said.if you have a vacuum leak it should kill 4 cylinders.

 

id do a compression check on those cylinders first... if theres no compression then figure it out from there

 

Yep, just got the valve covers from Napa, hopefully I can look into it the next day or so, really hoping that it just bent one or two, or the valves need adjusting, does anyone know the specs on them?

 

Oh, oh, pulled the valve cover on #1 side,,,, no pushrod for #1 intake, and #2 intake pushrod was in the head, a bit tweaked, got it out. Pulled drivers side valve cover, missing pushrod for intake on #7. So the question is, can I leave them in there until I get a chance to pull the engine, it is not going to be making any trips, just mainly around the property, or down to the mail box. Is it a closed in valley, where they can just lay in, I have never had a 292 apart,,,, had a few other V8s and sixes apart, just wondering if that is a closed vally, and they can lay there for another while until I decide what I am going to do with Mater.

 

Y-blocks are so simple, I'd buy new intake & valley-cover gaskets and a few new push-rods and make sure I fished out the fallen push-rod. Check for internal rusting, and damage to the top of the lifters. Test Suspect valves, you can remove the sp, make sure rockers are both have clearance and use a piece of new 1/2" rubber hose and blow into cyl to check for air bypassing a stuck or bent valve.

The intake manifold is super easy to R&R on this model engine.

 

The valve clearance on all the Y-Blocks is .019 Hot. When I say all the Y-blocks, I am referring to the 239, 256, 272, 292, 312 series of engines with stock cams etc.

 

Thanks, I have not had a chance to do anything as of yet, I got 3 new pushrods, was going to order an upper set of gaskets. Was just trying to avoid the extra time on Mater until I can do it by pulling the whole engine out and rebuild.

 

Pickup you can let those pushrods in the valley for now, they won't
go anywhere. It was common practice back in the [day] to let pushrods in
the valley till it was time to do other engine work.

Thanks Hot, I was kinda thinking so, seems how there is no place for it to go, its not like its my commuter truck! Cept maybe commuting to the mailbox an back.
