So i was going over my vacuum lines to check for clogs and deterioration and i noticed something really odd. On the line that goes from the throttle body to the oil filler neck ther was some kind of yellow greasy substance, alomst looked identical to that of butter. Its also all over the inside of the filler neck around the vacuum opening. I checked the oil, and it is fine, i have no idea what it is and have never seen it before. Im thinking it may be some kind of build up, but ive never seen it in that color. Any ideas on what it could be?
Condensed oil vapor. The PCV valve sucks in fresh air from that hose. A large ammount of buildup might be caused by blow by in the cylinders. How's the compression on the engine?
its "Parkay"..............lol.I believe that would be condensation and oil mixing together.Ive also had this before.
How bad is it to have that oil/condensation mix, and what do you think causes that? And i have no clue what my compression is, i know that my pcv was disconnected and the filter in the lower intake was totally clogged
Your oil baffle in place?
The cold weather along with high humidity doesn't help any....
What is an oil baffle? I Drove the car from florida in september before it started getting cold here in tennessee where i live and i havent driven it since, just let it idle and up and down the road testing. The oil looks good too.
Build-up like you described is really common in vehicles like yours that are taken for frequent short drives; Never being given a chance to really warm up thoroughly. That's your problem right there. You probably aren't even getting up to normal operating temperature when you make those short runs. That's really hard on an engine. Not good.
Well i always let it warm up for about 10 - 15 minutes before i even take it out of park i know the importance of letting a car warm up especially an older one. Ive just never seen that before and was hoping it wasnt something major - i plan on replacing all the lines so that should do it.
Look down your oil fill cap. If you can see the rocker arms, your baffle is gone/removed.
Does it hurt anything being removed?
It sure does Buddy. That baffle in your pass side valve cover is there for oil control. It's there to keep oil from getting sucked into your intake. You definitely want to have a baffle in that valve cover.
well i just took a quick look at it and im not sure what it looks like but on mine there was a plate lookin' thing:hick: below the filler neck and i didnt see the rocker arms
You're good to go then. Your baffle is still there. :D
Well thats good to know, hopefully changing the lines will cure most of my probems
Make sure the t-stat isn't stuck open and that the engine is getting up to temp. What you are seeing is very common on cars driven short distances in cold weather. Idling the engine in cold temps isn't good for the engine either and will build up condensation in the engine.
So whats the cure for that?
Make sure the theromostate is closed when the car is cold (ie the upper radiator hose should be easy to squeeze when the engine is started and the car is cold as no water is flowing through it. If it's firm when the car is cold the t-state is stuck open). Also don't idle the car when it's cold. I drive my 95 all year and even when it's below 0*F in the winter I just start it and drive off. I do start the 88 1-2 times a month in the winter but only when it's above freezing. Plus before I drive it in the spring I change the oil to get all the out that forms from sitting for 5 months.
Well im going to repalce the vacuum lines today, but im not really sure which ones i should replace, where all the main vacuum lines really are, anybody got a link to a diagram?
