noisy lifters after timing chain replacement
Was plowing snow in low range of course (basically just off idle) and the engine just quit. Wouldn't start but just knew it was the timing chain. 360 has an edelbrock performer kit (chain, cam, intake and 4bbl carb) with about 100K on it. Ran really strong with no oil consumption (could pull the mountains around here in 3rd (400 turbo quadra trac) with no problem). Ok replaced the timing cover due to scored oil pump gears, fuel pump eccentric, fuel pump, another edelbrock timing set and new oil pump gears. Tolerances came in to spec on oil pump. Before had about 40lbs. oil pressure at start up then drops to 20 and even less at idle monitoring crappy factory gauge. After is the same senerio but hung a gauge on at pump and actually reads around 20 at idle which I can live with. The problem is the valve train is for better words clattery which it wasn't before the timing chain went. Been driving it so lifters could pump up but no change. Really noisy at start up then quiets down some after warm up. Engine runs strong as before, even better. Didn't pull any valve covers yet (waiting for the weather to break) so don't know if rocker arms are loose or if the upper end is actually getting any oil. Any suggestions before I tear into it would be appreciated. Thanks.
