smoke coming out of valve cover.

yeah subject says it all. not the pcv valve the other hole. what is wrong?

smoke or steam....could possibly be blowby from bad rings...cover it with your hand to see if there is pressure inside crank case.

aight i will check it tomorrow. i just put new rings in in though. i could see it coming out of the louvers on my hood as i was going down the road.

mine blows oil out of the same hole. What is it?

im really not familar with b2200 motors cuz i basicly ripped mine out a month after i bought it..is your pcv valve functioning properly?..what is this hole..the oill fill hole?..whatever it is it seems like you have to much crankcase pressure..when you put the rings in did you index them propperly?.did you hone it?.did you check your bore dimentions to make shure they were in spec. and not oua round? .

How about a leak in ur valve cover gasket letting oil drip down on ur exhaust manifold? Or blowby from ur valve seals?Or ur truck decided to smoke dope/Lol>BJ

is it coming out from where the breather filter is?

it double posted for some reason...

yep. exactly where the breather is on your valve cover. and SOUTHERNRAZED it is building pressure. i put my finger over it for a few seconds and i could here it when i took it off. i did hone it out but didnt check my walls and talked to my dad about it today and he said i was supposed to use oversized rings. i dont know. BUT i drove it today while it wasnt so hot and not as far of a drive and didnt have the problem

You would only use oversize rings if it was bored out larger !! honing wouldn't remove enough material to go to a larger ring.
