trying to figure it out by taste cuz everything else isn't working. I'm going to disconnect the h pipe and start the car with open headers for a few to see what side the water is leaking from and I guess start pulling it apart for head gaskets

Do you use regular ole [green] antifreeze?

Also... Can you post an image of your firewall and the top of the header on the passenger side? It might be tough to get a snap of.

I'm going to have to back through the thread and see what was talked about. I've forgotten.

Ya just the green antifreeze and water, I'm sure there's a lot more distilled water than there is antifreeze. I can take some pics when I get home, The pictures I posted now are from when I did the top end kit. Don't mind the fuel pressure gauge just laying there that was just for start up, and all the wiring has since been cleaned up. I do have a question. I got the trick flow gasket set that has like the rubber around the ports built into the gasket, do you still need to use silicone around the water porch with those gaskets?

Are you actually losing coolant? I have literally seen vehicles pour water out of the exhaust.

So yes I'm losing coolant but now I also figured out the bottom of the water pump gasket is leaking so that could be the coolant loss. The water coming out of the tailpipes is clear water. What's in the radiator is green mixed with distilled water. Also last night I pulled the h pipe off, started the car and let it warm up to temperature with open headers and not a drop of water came out of the headers.so it's got to be somehow the exhaust somewhere is full of water

Looking through your images:


It looks like you have eliminated the water pass-through for the TB. (can't pickup anything there then, can ya? )

What do you got going on here?

That's the pcv feed line goes to the T, one end goes to the throttle body other to the charcoal canister. That's how the Holley systemax instructions say to route it. But it was pulling some oil into the throttle body so now it runs thru a small oil separator first then back to the TB

Well guys, I don't know for sure what it was but it had to have been a head gasket or intake gasket, because it's fixed now and the car's flying! Those trick flow 11R heads and that 125 shot are working good

Ya it does never had issues with it before so I never changed it. And I ran the crap out of the car. It's been sprayed with a 125 shot probably 100 times , and ran amazing before the top end kit

Is that a 125 shot of nos to the wheels or crank hp?
