cascadia possible overhaul

ok so my truck is in shop. im driving i hear tok tok tok. smoke loses power. im on shoulder within seconds. i check oil dipstick and smoke coming out oil looks fine. i check again after 15 min and oil and coolant mixed. coolant is slowly going down. 715k miles. and oil dripping from bottom of engine. a puddle. so im preparing for worst. crankshaft, pistons, head. anyone had this experience yet?dd15 2012.

 

i doubt. trust me. tok tok noise is something bad. gonna be screwed

 

i hope i hope. but i dont get lucky much.

 

i had pistons and rocker arms replaced. he replaced lots of other things too. but now im having huge high oil pressure issues. its very very high then stop light comes on. and im having some coolant leak. not sure what this could be. getting ecu 0 and cab 33 fault

 

its great. strong! issue is i cant go far without stop light goin off. u think its oil pressure sensor?
