Thermostat Whoas

Well I was afraid of this.....
The temp wouldn't come up over 165°F
I wanted to work on the 8T BUT FIRST: I had to go clear some more downed trees from a windstorm, BUT FIRST: I had to work on the chainsaw ...yada, yada, yada
So I haven't been able to even look at it in the light so took my drone down to take these pics
I haven't seen ANY smoke out the exhaust and I've been keeping a close eye on it.
Last time I checked for blowby (2 starts up ago)  it was negligible.
I'm thinking I've lost a ring, maybe?
I could use some advice here. Please

yes that's starting to slobber bad, hopefully it's not anything more than getting fully up to operating temperature by loading up engine and building some heat
-ring problems are possible but i would guess not likely unless you've feeding a ton of ether etc...
-has engine oil consumption increased dramatically? any other changes?
-does it have a turbo? just wondering if a seal is lost somewhere...etc..

Thanks for responding
No it is natural ex-asperated LOL D318 8T12801 ... not real sure but it looks like a later style thermostat housing 8T14xxx but It was dark, late and cold so I could be way off here.
No changes at all.::: NO ETHER only one time on pony! ...on first start:: The diesel oil is dark and thick (changing before next shift) and holding fast ... haven't checked yet today.
I have a long video on YouTube of it starting the day before I found the oil. I shut it down like normal and it was dark so I didn't notice the oil until the next day ... in the dark ( winter time in Alaska :rolleyes2: ) saw the oil and sent down the drone during daylight (dusk( winter time in Alaska :rolleyes2: )) today. It has not run sense I found the oil slick.
temp the day of the start it was 10°F and caught the last few RPMs of the pony as it run out of gas to start the D318 diesel... The D318 has ALWAYS started great even at subzero.

if you want to jump to the grader starting FF to @9:50 and as it was warming up. FF to:@17:34

Sorry ACMOC but I would only have rip up one of your magazines as a LAST CHOICE and besides that Steiner was out dated - ACMOC Magazines never expire...

Many old Cat's will slobber like that if left idling for to long. Put it to work, and most still preform well without a lot of oil consumption.

So yes good thermostats could help. The last new ones from Cat that fit the D318 read made in China. So check the old ones out well before pitching them. In your conditions might try getting a suctions fan so you can put card board on the radiator to help raise the engine temperature.

Thanks Ray54,
I have heard the new thermostats are less then even China's specs so I've been reluctant to grab some. I did look at some early videos of the 8T and saw prior evidence of oil dripping down the muffler but no where close to what is there now.
Found some GENUINE OEM Caterpillar CAT Temperature Regulator (Thermostat) 247-7133
I can't find any kind of conversion numbers for 247-7133 ... Will they fit?
they come in 180° or 190°. I've always used 190° in my vehicles in Alaska

I will not say it cannot be done but the Cat unit are said to be the only easy fitting replacement.
