I have some info to share and need your advice. My truck has a couple not so good injectors
And possibly a seeping head gasket? Said my mechanic . I was told it has a litte more than normal pressure. I just had my first puke issue after 220, 000 miles so I changed the degas cap to a cheapo? It was goot to go but thr bottle looked stretched at the seam ? So I loosened the cap a little . I put the sct tuned by kem on the truck RACE tune lol. But made sure to take it real easy on it like a old woman on sunday lol. Trying not to build boost maybe 10lbs or so . I took a family trip from Illinois to Missouri the Ozarks to be exact. Tried to be easy but fast on the downstroke of the mountains and use mainly momentum to climb? I lost a gallon of coolant but didnt overheat and same on the way home but now my coolant smells of fuel. Do you think its a injector issue. That is causing the coolant contaminants or cracked head? What do yo recommend?
