alright fellas it looks like no racing for me on saturday or anytime soon..... the last time we ran the car we pulled a plug from each bank and took a quick look at em to make sure all was well. car wasn't missing as far as we knew so we figured all was well.....
well today on advice of my electrical guy we decided to do a compression test... we pulled the #2 plug and immediately we were like "OH SHIT".. The grounding strap was completely burned off the plug and the plug was fouled bad with oil.... I had idled the car in the garage a few times since that day and with the plug not firing it just washed the plug down with fuel and oil... it looked bad....
a compression test revealed that we are down another 20 psi from what #2 tested last time which was like two months ago. #2 was 185 and all the others were 205 back then... now it's down to 160 psi and the others are 205.... so that hole is having a serious oil control problem and if I had ran the car on saturday unknowingly it would have DEFINITELY melted down that cylinder probably BAD. So finding it early was a good deal for me. Now I can just replace the piston and reassemble the motor and we should be good to go.... but the pistons are custom ordered and I believe they have to be ordered in sets of 4 at about 500 bucks for 4..... so it's gonna be a bit b4 i can get the motor out and reassembled......
I'm not at all mad at it.. that's racing and the 9.06 makes it one of the fastest LT1's in the world so this motor far exceeded my expectations.... and since i found it before it exploded bad it only needs one piston.... I can't be mad at an engine who pushed a 3400 lb tank to a very low 9.....
So pour out some liquor for my #2 piston this weekend cause she's a dead homie... http://ltxtech.com/forums/images/smilies/cust/gr_wink.gif
