Before going to the trouble of installing a baffle in the pan, I’ll suggest checking that the oil pickup is not placed too far up from the bottom of the pan. Maximum distance from the pan bottom should not exceed 3/8”. Ted, problem turned out to be pickup tube too high and oil ran away to front while going down slopes or hills. it was due to unnoticed bent pickup tube and then when lining up into oil pump nut swung the pickup in upward arc and was too high. From my observations there is one rear sump that has a baffle windage tray type interior, pickup? then similar one that doesnt have it but is much deeper at the front section, truck? does the deeper application require more oil ? and what would be original capacity.? I fitted baffle half way to slow oil running to front timing case seal area. Thank you.

Based on the 1959 truck manual I have, the light pickup and MD truck oil pans take 5 quarts plus 1 for the filter. The HD pan takes 6 quarts plus 1 for the filter. The oil pickup and tube assemblies are specific to each style of pan meaning if the pans and pickups are mismatched, bad things could happen. If memory serves me correctly, the HD pan is approximately another inch deeper than the light pickup and MD truck oil pan. I'll add that I've seen the light pickup and MD truck pans with and without the baffles which means it's probably a year model thing to watch out for.

TED, thanks for reply, yes thats what i figuered, anyhow i added more oil and its good, back to 70 lb pressure. This metric measuring in litres as does the linear measurements confuse the heck out of me. At least now i have a guide to the capacitys. Thanks again. regards bill.
