Developed a loud tapping noise in the engine on the way to the track Friday night. Got some blow-by out the breather. Pulled the plugs today and did a compression test. Not pretty. I only did one side, because it was pretty evident that #7 had a problem.

Here's the #7 plug.


Here's all plugs and 1/3/5/7 compression numbers.


So....looks like the motor has to come out again.

 

Damn buddy. That really sucks. Were they forged pistons?

 

damn, and this is with the forged motor huh?

Im sorry to hear this bro, blame KB for the increase in air velocity and make him pay.
JK...


You and KB have injured motors!

 

What kinda boost and timing are you running? That was forged right?

 

you have had nothing but problems with your setup.. go stock lol sorry to hear

 

I think your motor and KB's motor were BS'ing one eve and said screw you both....

 

It's our new room mate!! He was in my truck when it first pushed coolant, and he was also in Chris's truck when it when south! lol!!! J/k mike

 

Yeah they are Wiseco pistons. I was running about 10 psi at the time and 16* of timing.

 

that isnt much of anything to do damage..i wonder if something else was the culprit.. didnt you have denotation problems before?

 

Sorry to here that the #7 is toast. Was this caused by running the motor to lean or running to much timing?
