CAT c15 mxs

Did they check the liner protrusion when replacing the head gasket?

 

There are some extremely good folks on here that can help you out with a complex procedure,troubleshooting a blown head gasket. The Superstars or Diesel Mechanics. I am sure one will hop on and help out.

 

Yeah man the mofo who specializes in doing cat single retrofitting is a cool cat name Miguel. Shreveport Louisiana .His shop is called Fleet Deisel Services . That cat can rebuild em with retro turbo with a blindfold . I'll be going to him with my bxs when I get some bread. These rates are killing me

 

My cat guy has been real good with my sdp engine and while we have eliminated a few things and played with the computer he absolutely recommended against eliminating the actuator s......i.m at 1.2 million most of my mods were done at 750 truck has been a consistent 7.3 mpg and still have stock turbos....he told me quite a few guys with the actuator and single turbos have blown head gaskets soon after

 

Oh yeah man I'm not gonna be changing my configuration either. My bxs has 1million-89thou with no major internal work. One of the iva's went out last year but they are simple to swap out .

 

if its blown a head gasket its because a liner has sunk. the only way to fix that is to remove the liners, counter bore and shim the block. otherwise it will keep blowing head gaskets.

you also need to use 16:1 comp pistons with no IVA. 17 or 18:1 results in too much cylinder pressure and will lead to premature failure of the head gasket

 

yes and thats cuz they left the 18:1 high compression pistons, if u remove ivas vva and go to single turbo u need 16:1 low comp pist, n itll run like a champion
