I just bought a new dodge which is slightly modded. Tonight when i was getting into my truck i accidently hit the switch for the water/meth injection and didn't find out until a few miles down the road and my truck stalled. I tried starting it for about a half an hour and finally pulled the intake boot before the intake elbow and then it finally fired up. When i got home i checked my coolant and it looked like mississippi mud!!

The truck seems to have good power but im worried that I may have pumped too much water/meth into the engine to blow the headgasket. I do have gauges and did not notice the boost levels to exceed 40 psi under any circumstance but Im just sick about everything.

What should I do next? I think i blew a head gasket by the color of the coolant/oil mixture which really makes me even more sick to my stomach?

Any opinions or suggestions? The truck is a 98.5 24V with 100 hp injectors, water meth combo, & edge comp programmer

 

If you hydrolic-ed the engine at highway engine speed I would guess there would be more then just a blown head gasket. (try bent conrod and a ton of engine knock.) If you did it at idle, there is a chance that you popped just the headgasket and didn't do any further damage. However, since you just bought the unit, used, it may have been full of mud before it fell into your hands.

(pull the fuse on the water/meth pump)

(check the dipstick before you restart it, as you don't want damage the bottom end with coolant.)

Start and idle the engine and see if the cooling system pressures up, or if the crankcase fills up with coolant. If it dosen't pressure up, watch for white smoke at the exhaust, cause then it's leaking into the cylinder(s). If there's no cooling system pressurization, white smoke at the tail pipe or mud in your crankcase, get the cooling system flushed and forget about it. If you did blow the head gasket, be happy it's a straight six with only one head, and look at the bright side, your valve lash will get set.

 

try pulling the dipstick and seeing if any white frothy liquid is on the dipstick

also do what qmc said

hope this helps

 

All blown head gaskets I have seen caused intense bubbling in the radiator. Check to see if you have it. If not you're probably Ok.
-P
P.S. With the engine running that is, of course.

 

Is there an arming switch for the injection pump, with a boost switch to initiate the solenoid(s)?

If it just has an on/off switch....

That's why we design our H2O/CH3OH systems with safety features!
