yo; just lost my entire reply to you bec of this freakin laptop's bad batty
summary of what I wrote over last 30 mins.
ck PCV hose to manifold, in case it accident fell off.
ck breather filter in air box... the breather system becomes blocked the crankcase pressure will build up. The only way out for the gases is via the dipstick tube which tends to throw out lots of liquid oil as well.
ck out
trucky's breather tube filter mod
hopefully it is above and not "blow-by"
"If you pull the PCV valve out of the cover, can you feel air being forced out the hole in the valve cover while the engine is running, or can you see puffs of smoke coming out of there? That is the blow-by test. If the combustion gases are in the oil pan, valve cover, or oil gallie-ways, this makes oil spit out of the oil filler hole, dipstick, and anywhere else it can, i.e. it will try and blow the rubber gasket out of your oil pan if given a chance. Blow-by is bad. You could try goosing the throttle by hand while under the hood and try to witness if any oil shoots out of the dipstick..."

my truck used to run hot and blow oil out of the dipstick. The radaitor was plugged up and blew a leak. Changed out the radiator put in a 180 thermo and it hasn't done it since i put that in. by dt
I would keep an eye on the overflow tank levels. Watch for mysterious loss of coolant. If the radiator is original or very old and has been not been maintained, you may want to replace it for piece of mind. A new rad can cost as little as 150.00 bucks.
in same thread...
btw....
REROUTE THAT PVC SYSTEM
Problem:
Failure of the #8 piston or the #8 rod or rod bearing in Ford 5.0L, V-8 gas engines
Applications affected have been in 1987-1993 pick-up trucks and vans. After discussing the situation with several installers, the problem has been narrowed down to the PCV system.
Solution:
During engine installation, reroute the PCV valve vacuum supply hose. Follow these steps:
Plug the 3/8" (pipe) thread hole in the rear of the plenum where the PCV valve hose is connected.
Drill and tap a 3/8" pipe thread hole in the center of the plenum and thread the PCV connector into it.
Reconnect the PCV valve vacuum supply hose to the new location.
Be sure the drain hole in the baffle is open. The baffle is under the PCV location in the valve cover.
Installers who have rerouted the PCV system and opened the baffle drain hole have not reported any #8 cylinder failures."
