Need to replace oil dipstick tube on 1990 silverado

SOURCE: Oil blowing out the dipstick tube

a fairly common problem on any of those high mile or abused 4.0liter engine either #1 your PCV ventilation tubes are plugged those are thos small black lines comming out of your valve cover or #2 your getting really bad blow by in your valves. 1 being easy to do and 2 not so easy!!

SOURCE: oil dip stick

Had the same problem last year - the plastic handle broke off and the top of the remaining plastic was visible down the tube but was stuck solid. Finally used an easy-out to get it out. Drilled a small hole into the plastic and then threaded a thin easy-out bit into the hole and it held enough for me to pull the dipstick out. Stupid design, a plastic handle on a metal dipstick!

Here in Canada the Intrepid is badged as a Chrysler. Sounds a bit dodgey to me :-)

Sorry to say its your head gaskets. Probably from the overheating it wore out the gaskets. that milky stuff is your coolant mixing with your oil. Good luck. Suggest you take it to a pro. the gaskets are easy to change, it's everything else in the way to get to them that requires special tools and experience. Let me know how it goes. I have the same thing with my truck but not real bad. If your truck is running smooth and doesn't feel like its missing, or when your start it no puff of white smoke comes out your exhaust it's not that big of problem. if these are happening then i would get a quote.
