Ive got a 1982 f150 with the 300 i6 in it. its blowing oil badly out of the oil filler cap back into my breather housing and it blows oil out of the dipstick . Theres also a white creamy stuff on the oil filler cap. It blows smoke out of the filler cap.badly when its running but never blows smoke out the tail pipe. ive been told its the rings but idk any help would be greatly appreciated.

 

Does it have a pcv valve and is that valve hooked to a vacuum source and working properly?

 

Yes sir it does and it is hooked up
but every time you run the truck it pops out

 

1. The white creamy stuff is a result of cold starts and short trips especially in the cooler seasons and it could be plugging/gumming the PCV valve. 2. A compression check is in order.

 

Ok i really appreciate it and il make sure to get it checked out
