so i just finished putting my flux 2.5's in and head studs got real excited to drive it and when it started it up it was poping real bad and loud from under the hood and some white smoke coming out the tail pipe... with the head studs i took them out and replaced them 1 by 1 starting in the middle and working my way out 100ftlbs then went back over and went to 130ftlbs... any in put... dont want to rip apart the motor if its just something stupid

 

When I cracked the cylinder wall easy way to tell was water was leaking out the exhaust. Maybe you didn't got a tear in the gasket and didn't relize it? Are you positive it's white smoke and not like a white mist? Another way is when it's smoking like that put your hand next to the exhaust and see if it's real watery? If it is a head gasket I wouldn't let it run to long you might do some real bad damage if it get's vapor locked. Maybe something real easy but from the way it sounds you might have to pull it back apart.

 

Do you have a bunch of air bubbles in your radiator/surge tank? Has the coolant level dropped a lot? Did you let it run long enough to get the air out of the fuel system after changing the injectors? You should not have blown out the gasket just from changing the bolts to studs. Was this some kind of pre-existing condition or maybe it didnt run quite right? Sorry for all the questions but it helps to pinpoint the problem.

 

Did you even pull the head or not? If you didn't pull the head really doubtful that you blew a headgasket. There was one time that my fuel filter was clooged and when I got on it real loud popping like a shotgun blast and a short puff of white smoke? Will it sit and idle? Is it a constant flow of white smoke with alot of popping?

 

Sounds like a injector/fuel delivery issue and or maybe a valve not adjusted correctly,pushrod not seated in a lifter etc.I think other then the head studs you need to go back over the injector install.

 

kman9090 what is the chance maybe tomorrow or some time next week you could look at it... i will pay you to if need be... the truck is in south county..... you should still have my number in a pm just give me a call if you can ... no i did not take the head off.... and there was no problems before this???????? it will sit and run but it has this loud popping over and over... fuel rail says 7,5xx if that helps

 

I would recheck the valve lash.Did you keep all the rockers in order so that they went back where they came off?

 

thanks for all the help guys... got the valves adjusted yesterday and it runs like a champ

 

Is that what it was? Valve floating? That was the first thought that went through my head...
