Hey Scottie I have a 1989 2.5l manual trans Jeep Comanche base model 250k miles. There is a lot of tan foam coming out of my dip stick and engine breather when running at temp. This just started happening as the temperature starting dropping into the 30s I live in Oregon. I’m not losing any coolant and my truck isn’t overheating. Also my dipstick smells like gas. PLEASE HELP
Please post your mileage per the instructions. Thanks.
Sounds like oil dilution from cylinder blowby.
Perform a cylinder compression test to see if your piston rings failed, which wouldn't surprise me on a 30yo car.
You could try a new PCV valve, $3.99 at AutoZone. But, like MountainManJoe said, if it's excessive blowby from worn rings, you need an engine rebuild, or rings and rod bearings at the least.
