360 oil problems

[hi-boy76]

Hi everyone, im new to the forum and have learned a lot just reading some other posts. i have a 70's f250 with a 360 and im burning oil real bad. i know its on the drivers side because it only smokes out that sides header. i did a compression test and all the cylinders are within 15% of each other so i don't think its rings. when i did the compression test i looked at the plugs and the 5, 6 and 8 plugs were really carbon fouled. my coolant is muddy looking but i dont know if thats from oil or rust in the system. there is a small amount of oil that seaps out the front of the intake manifold gasket. so i was thinking maybe its valve stem/guide seals or a head/intake gasket problem. Any help you guys can give me would be great, thanks.

snatch the valve covers off and look for broken/missing valve seals .. that`d be my first guess ..

Not only that but if the seals are broken up with age you'll find pieces scattered around on the heads and in the valley plus a really big binch in your oil pump pickup
