seen coolant all under my truck i traced it up to the corner or i think head gasket on pass side right above where the oil filter goes has nayone else seen this is it the gasket weeping on the corner or??? and how hard is it to take head off so i can get it decked and new arp studs n gasket??? i work on cars but ive never had a head off a cummins thanks guys!!!!

Might check it with the truck running. When the water pump is going out it will dump a puddle of antifreeze.

yeah it could be your water pump. i would do the head studs anyhow. are you boosting above with the 150hp injectors?

it happens but pretty rare , i would clean it up and put some pressure test the system and verify exactly where the leak is spawning from

doing the head on a cummins is crazy easy although i would get help cause its pretty heavy and service information actually tells you to use a hoist to lift it

good luck

while head is off get it o-ringed

Might be a cracked block too. but there is a water passage in that area.

Head weights about 200lbS deff head stud and fire ring it

well i drove it 300 miles today and had no leaks??? it doesnt over heat or anything stay at about 190ish and i only boost 32psi nothing crazy fire ring it do i have to just get head ringed or block to im looking to just get stock head gasket with arp studs??? i heard you onyl want to use stock head gasket no aftermarket ones, ill have to clean it up tomorrow and see if i see it leaking and pressure test it


oh and i noticed it may look like coming out of that little 3/8s plug and fan blowing it over on the side

Has the head ever been off and the fire ring get machined to the head

If the heads never been off I would just use a stock gasket

no heads never been off

Don't fire ring it, it will give constant issue.

heres a picture of where i can see puddles





and its leaking over to the other side of the head where thermostat is im guessing head gasket for sure i really dont want to change i was hoping it wasnt leaking

I wouldn't fire ring just do a new gasket and at least the mid strength arp head studs I know guys running a 120psi of boost on the stock gasket with the high strength stud I've pushed 70 on my 06 and I just have a stock gasket and the mid strength stud

Filtering is a lot more common on 2nd gens tho they arent as strong as the 3rd or 4th gens my 02 is fire ringed got about 4000 miles on it all drag racing haven't had a prob yet

what all gaskets do i need head gasket manifold and valve cover seal

Valve cover seal isn't needed just don't mess it up when you take it off and all you'll need is the gasket between turbo and manifold also your heater grid gaskets I'd leave the manifold on the head you can use it as a handle
