but what? Heads just came back from machine shop and all is good. I replaced the damaged one. The sleeves weren't cracked as when the heads were pulled I looked at them very carefully and multiple times and didn't find any damage

 

Don't know , heads were pressure tested? Block decks are flat ? Can you narrow it down to a cylinder by the plugs? That will be difficult with newish plugs but maybe worth a try and while they are out you could try to put shop air in the cylinders and see if any goes into the coolant - it's not near running cyl pressure but it may show something

 

1 head was actually replaced, both were pressure tested, new head was cnc port n polished to match existed head that was kept, both were milled to .040. Original mill was .030. Nothing was done to block, block was never removed from truck. I was thinking pull intake manifold, valve covers and pull rockers so valves with seal and pull the valley plate and pressure test the coolant system like that. My thought process is it should show me like that because I see the coolant under the valley plate and technology with rockers pulled the valves should seal and show me the leak?

 

Tommy I replied on PT.net as well, go check the HG orientation. Make sure you are not the victim of mis-labeled gaskets and that the tabs on the bottom of HG's are towards the front of the motor.

 

I wish it was that simple man, unfortunately I know to line up the cooling ports

 

You near Nola? I have a friend there who could take a look unless you got people.

 

I'm fairly close to that, im in Prairieville. Ill do the leak down test and see where that gets me. I've talked to a few guys I know and everyone is pretty much telling me the same thing, do the leak down test. I wouldn't mind having a good contact in the area tho.

 

Has been holding a consistent 15 pounds for about 1 hour

 

Does it still overheat or anything or is your only symptom now the bubbling?

 

hasn't overheat yet, it's bubbling pretty bad and exhaust is wet again, misting like

 

Held 15 pounder all night

 

You sure the exhaust isn't fuel? If it held 15 psi all night but you really do have coolant getting into the exhaust then it sounds like a block or head issue that only shows up when warm, assuming the new head gaskets are good. But if its not overheating I'd get some miles on it and see if your coolant level is disappearing.

 

doesn't seem to be fuel, it makes a spot on the concrete below the muffler tip that looks like what coolant would look like if it were on the ground. I pulled the intake and valley plate yesterday and didn't see any signs of leakage or damage below them. I torqued my head studs to 80 pounds, should I go a little more and see if maybe it's not sealing? I rained out from work today and the wife is out of town so I want to hit this thing hard today and try and get it figured out so I'm open to any suggestions, also I went 28 pounds on the small bolts. This is arp studs

 

Hmm seems to gave stopped, I ran it for about an hour without the radiator cap and the bubbling stopped so hopefully it was air and I tasted the liquid coming from exhaust and it didn't taste like coolant or fuel, really it tasted like water but it also stopped

Condensation from combustion gasses in cold exhaust system.

 

Well I think my luck may have finally turned around, I just took the truck on a 45 minute joy ride and it ran beautifully, no check engine light, temperatures look good(didnt overheat), afr look good, no water in exhaust. Fingers crossed but I might just be ok

 

Man this thing is going to be a ripper once I get the settings on this turbosmart eboost street boost controller dialed in, 40 mph roll a little more then half throttle it smoked the tires and pulled out pretty well. I had my overboost set at 15psi and the spi at 20 so the boost was around 7 psi. This afternoon I'll turn that duty cycle up a little, im aiming for around 14psi for now and we will see how that does.

 

Tuner told me don't go much over 14 psi, I'm at 13.9 so I guess I'm safe haha

 

On pump gas sounds like a good idea.

Glad you figured stuff out.

 

Im on e85 and yeh things are looking much better. Im still going to put a better radiator and drill thd holes in the thermostat. Just for a little extra security. This weekend im going to let me tuner take a look at it again. Just to make sure everything looks good and next weekend the local track has TNT so I'll go try it out there
