Hi, all. '95 K75. 30,000 miles. Sits in my heated garage all winter and is, frankly, a garage queen. It's never spent the winter outside here in frozen CNY, garage is 55 degrees F all winter.
Gave her the oil change/filter the other day. Brake lines bled yesterday. New front tire on order. Took her for a short spin to test efficacy of brakes and to have a brief 'summer' feeling.
It seems the issue emerged right after the short ride. Oil was light honey clear beforehand, but when I checked oil level for top-off afterward I noticed the discoloration in the window and could see some milkiness inside the filler cap. Also looked like droplets of water inside the top of the filler cap.
Drain hole was cleaned/explored/plunged, there was one wet droplet on my finger afterward. I haven't taken off the tank to examine coolant cap.
Yesterday I read a number of similar threads here about the 'mayonnaise' issue--water/oil pump seals/rebuild and/or blown head gasket, and I'm really trying not to retread over tired ground in this post--many similar threads have been here for quite a while.
Removal of pump assembly will naturally call for rebuild and examination, but what evidence would I be looking for with a blown head gasket? I'm certainly no mechanic, but the K has been a kind teacher of simple m/c maintenance and repair. Yet I've never taken the valve cover off--not sure what to expect.
Guess I'm asking whether there is any other possible explanation other than faulty seal(s) or head gasket before I launch into those jobs.
I am grateful for any input from the 'hive mind.' Thanks...
