Is this Evaporated Oil?

[RNajarian]

Mystery under my SC motor. In my oil drip pan under my car I have noticed these hard substances. I start my car regularly but only take it out every 6-8 weeks.

These puke green mounds are hard and will melt when a match is put to them.

The oil level/use in my car is consistent, no more or less loss than normal.

Two mounds have developed, under the centerline of the engine. The most distal being where the alternator belt cover plate is, the other about where the centerline of the case is. The engine itself has NO evidence of these hard wax like mounds.

When I flipped the mounds over the bottom feels and looks oily

I am using Shell Rotella T

Logic tells me it is evaporated oil but I am curious to what the brain trust thinks.
Any thoughts?

I use Shell Rotella 15/40 and have never seen anything like that and my car leaks quite a bit.

[RNajarian]

I've been using Shell Rotella for maybe 4 years now and this mound issue is a recent development. Hence the mystery.

Hey rolling terrarium dude, that stuff looks like the milky paste that is created when oil is mixed with water (yours being dried out now); has it been humid where you live?

[RNajarian]

No not humid at all, Southern California. Garage is consistent 75-82 degrees year round.

My money is a cat or a kid puked on the tray...

Maybe it's plant fertilizer?!?!

The view from RN's rearview mirror!!!

Condensate from short run intervals.
Get the motor up to temperature and that won't happen.
I never start mine unless I intend to get it up to temperature.

Clean your drip pan and then visit every day or so. Take a photo at each visit. I am curious what you find.

Both great suggestions, will definitely do both

You mean there is no similar type substance hanging off below but still attached to car?

Nope, just the normal drop of oil expected from these engines

[manbridge 74]

Hmm, does it have an odor?

[Rawknees'Turbo]

Too funny!

Sorry RN, I had you confused with another red Targa dude that I always joke around with about "rolling terrarium / can grow pot in the back of Targas" - you're probably wondering what the eff, I was on about.

Looks like too many carbs in your SCs diet. Looks like a ciabatta and a flat bread. Put your car on the Atkins diet

No problem . . . I thought I had made the big league by getting s#!+ from you!

[Rawknees'Turbo]

^^^

Big leagues all the way now!!!

Good thought but where is the source? And the mounds are tough. It took a screwdriver to break them apart.

No odor and no taste (the things we do for our cars)
