Blown Engine?? May have FU#@*%D UP REAL BAD KLR

Blown Engine?? May have FU#@*%D UP REAL BAD KLR

Recreational ride today 150 miles, mountains, and a sprint home at 80 mph.
Buddy says let's hit the carwash. I spray my bike down while it's hot. Worry immediately from the steam off the engine.
Ride home and check the temp after I park it for 20 min. It's only down to 170 degrees usually drops to 80 in 20 minutes.
Takes 30 minutes to drop to 135 degrees. When it was hot I opened the oil cap and with a flashlight I could see vapor rising out of my crankcase. Never opened it before but I feared vapor meant water was boiling out of the crankcase from me spraying the cold water on the hot block.and it cracking.
Let it get down to 114 degrees after a half hour. Idled it up and let it rise to 120 degrees. Turned off. Temp rose after I turned it off by 5 degrees and slowly started to cool. This bake has never risen in temperature after shutting it off.
So it's 2 hours later and the bike is still pretty hot to the touch. Fins on cylinder still real hot.
So did I crack my engine spraying cold water on it?
How can I tell?
Planning on draining the oil in the morning and taking a look at it.
What should I do? How can I tell?

I think you're just being hyper sensitive and noticing things you didn't notice last time because you weren't looking for them.

I can't imagine the car was water being any colder than my creek crossing, and I'm sure i get at least as much cold water, if not more up on the engine.

Temp gauge climbing is normal after after shutdown. Coolant isn't circulating, and the temp gauge is reading the head temperature. Opening oil filler hot, I usually see some "steam" for lack of a better word.

Is the oil cloudy? Is the coolant cloudy? Is the bike losing an unusual amount of coolant or oil? I really think you are being hyper sensitive.

That's not good. Like a chocolate milkshake? Coolant in the oil, time to start taking stuff apart.

I'd drain the oil and have a look, but it's not uncommon for a hot bike that's been washed or cooled quickly to have some cloudiness in the site glass from condensation. A good run that get's the bike to full operating temps will usually clear it up. If the bike is running fine and the bike temp gauge is running where it always is I suspect everything is fine. I honestly don't think it's possible to damage the bike with cold water.

I don't want to start tearing shit apart, not qualified man, but read my tale of woe below and tell me what you think.

Yeah I haven't washed my mule for 3000 miles. That's my first mistake is riding with a weenie with a BMW that gets a little dirt on it and busts open a can of starbucks frappucino in his pelican cases cause I actually got him off the pave ment where there's, ooohhhh bumps.

Ok so I drained the oil today, after running it a little. There was froth bubbles that covered half the oil pan. And the s--- looks like it has a green tint to me. And the last dribbles that came out sort of separated into their own little quarter size pool atop the oil.

I'm telling you I always watched the heating and cooling of this bike and the way it is acting is abnormal.

Why the froth? Do you guys get froth when you change your oil?

Unhappy Check before opening up the engine

I would check the coolant level before doing anything else.
If it is filled up to where you normally see the level, I would replace the oil filter and add new inexpensive oil to the proper level.
Then start up the engine and take a short ride.
Return home and let the bike sit and cool. Then check the oil level and coolant levels again. Also examine what the oil looks like through the viewing glass.
Also take a small sample of oil from the crankcase via the oil filler hole.
See how everything looks.
I wouldn't tear down my bike until I really knew that there was a real problem.
I don't believe that washing a hot bike with cold water would crack the block or head.
This ain't no toy or glass bike!

Be nice to see some pics of the oil. I have had condensation in my oil before, especially when the weather was cooler. Where is the temp gauge (bike, not your infrared thermometer) running? Is it in the normal range? As said before, there is no way to crack the cylinder or head with cold water.

Lol, just thought of something... If the carwash was bad for bikes there wouldn't be a Harley on the road today...
