The engine may need to be warmed up some before the leak shows so be patient. If its leaking, fix ASAP or much bigger problems will follow.

Spot on. If it's an auto load it up on the brakes or trans brake to make some boost.

I think he means to watch the gauge, while you're beating on it.

Good idea with a light.

Unfortunately not auto. It will make a few pounds revving it but that's about it. It will make about 10# on the 2 step though. Ill see if I can secure the gauge and make a pull with the go pro on it. May be difficult but i'm up to a challenge.

That and i would say point the camera to get a good view of the heads and see if they lift (spray) coolant.

Ill see what I can do. After I replaced the coolant cap the spray went away under the hood. I also noticed when I did the pressure check I forgot to put a clamp on the stem vent so im sure some spray was coming from that too.

So guess I'm screwed? Got the car to operating temp. Pumped it to like 18# and revved the motor. It gradually rose to 25# in about 10 seconds.

Would be nice if you folks who know would suggest a timing scheme for the OP.

A chance for the rest of us to learn something.

Here are the rest of the plugs not already posted. All look the same other than that one with the white looking strap. Not sure what's up with that.

I am not sure if it has been mentioned but what is your AFR for these pulls? Also, check your injectors to see if they have developed the black goo of E85 death. When my injectors went black I blew out the driver's side HG because it was lean but you would never know it looking at the plugs or otherwise.

Looking at the plugs won't tell you anything. Put dye in the coolant. Run the motor let the dye get around. Take the plugs all back out and hit them with the black light

Seems like if it was really pushing that much pressure into a cylinder it would be drinking coolant under normal driving.

Around 11.5. I have all ptfe lines and all fuel components have less that 6 months on them. Seems like everyone that has a problem with the black goo or rust let's their car sit a lot. I drive mine or atleast start it and run it to temp once a week minimum.

11.5:1?

Are you reading A/F values for E85 on a gasoline scale?
