Mayonnaise

You guys have never owned a Ford escort, have you ? LOL. Every one of those 80s 4 poppers would look like that when you popped a valve cover, or pulled a dipstick. I always thought the aluminum head has something to do with it.

My Grandparents bought a 66 mustang brand new. Grandma drove it.
She only went to 3 places. 1 hospital, where she worked 1.5 miles away. 2 grocery store, 1 mi. Away. 3 my uncle-cousins house 3.5 miles away.
By 1986 she only had 60,000 miles on it. Car ran good and looked good! My Grandparents did keep the oil changed but still, the engine NEVER reached operating temp on her drives. So mayonaise in the crank case. They rebuilt the motor due to the goo in crank case. I still have the car. Mayo was due to condensation never evaporating off from normal engine temps.

The 2000 Grand Cherokee 4.7 ltr my daughter drives gets it inside the oil fill cap sometimes. It has over 250,000 miles on it. The oil stays clean, though. No water it.
