7.3 powerstroke head gasket
driving the truck down the road and noticed the temp jumped from 190 to 290 like in a split sec. now i have white smoke out of the exhaust and smells
like coolant. i think its a head gasket but what are your guys opinion. show i do a compression test or what first please help thanks |
stockish truck I would suspect an injector cup not headgasket...
Do a compression check and go from there. Head gaskets almost never fail in a 7.3. |
what kinda compression should there be like how high
|
Depends on the motor... Mine right now is between 320 and 360 for all... And that is considered low. 360+ is what I would expect on a healthy motor.
|
Do you have any kinda chip or anything on it.
This is exactly what happened to my truck a year ago. Ended up with all 8 injectors cracked and both heads cracked everywhere. Just happened out of no where with no warning. I hope your your sake its just an injector cup. |
it has only of those bully dogs six position on it. its my buddies truck and im working on it for him. do u have to pull the glow plug for the compression check or the injector and thanks guys for your help
|
