I own a 94.5 7.3 psd F450 superduty with about 180,000 miles on it when warmed up and idling there is what looks like smoke coming from the dipstick,is this what you call base compression and what kind of trouble am i looking at
I am on my second 7.3 PSD and both have released a slight amount of smoke up through the dipstick. I suppose it is a bit subjective as to how much smoke is coming out of the dipstick if it is billowing out then there is a problem but if it is a small amount I would say no problems and it is normal.
Most times that is caused by piston rings not sealing well. The gases in the combustion chamber leak past the rings and into the crankcase. The crankcase has a crankcase vent system that allows the excess pressure to exit the motor into the intake so that the engine reburs those gases. You may have a minor problem with the crankcase venting system. You may also have a problem with excessive blowby from the piston rings and the crankcase vent system can't handle all the gases coming from the rings.
Is it the dipstick or the filler tube?Just want to make sure what part it is.Also is it really cold outside because if it is you will see some steam coming from there because of the heat escaping from the motor.
I would start by replacing or removing the little filter in the CCV on the valve cover. I would imagine in a 10+ year old vehicle it's probably close to plugged.
It's easier than a compression test and a ring job anyway.
