A little short of 400,000 miles. Keep us posted on what the diagnostics reveals. A lot of blow by is not good. Is the engine oil still clean?
Looks ok no white smoke from exhaust though.. It's leaking coolant from the coolant drain pipe not much though drips at turn off or start up. white smoke coming from oil drain pipe might be cause of the snowy weather?
Update ***** Got truck back from dealer. So 1 of the 2 hoses I replaced 2 weeks ago was leaking and needed re clamping.. And other side of the engine was another hose cracked from.the back where you can't see it.. So when I was starting the truck The fan was blowing it every where.. Plus needed a tensioner replaced as the new belt I put in last month was already worn from one side..
