Many of you have been following along my previous threads discussing the issues I have been having with my built 347.
To sum up, it was burning oil from 2 cylinders. The plugs in those cylinders would foul within 30 miles.
I got to the bottom of it tonight. Ran a compression check...was perfectly fine. Did a quick leak down test by spraying air into the chamber and did not hear it in the pan. I was actually happy at this point and was hoping it was something in the head.
NOPE
Got the head off, and those cylinders have DEEP gouges running vertically the entire bore. When you feel the bore, it feels like you are reading brail. The other 6 cylinders feel great by comparison. I am already running slightly overbored at 3.905. The max you can bore an LS1 is for 3.908 pistons so I am pretty sure this block is screwed and cannot be saved but maybe you guys have a better idea.
Looks like I am smurfed. Andrew gave me a deal on that block since he is a friend at only $300. No way I will find another that cheap. I know the machine shop will try to avoid liability since it is now more than just a simple rehone and rering (they said they would cover that on their dime based on our previous discussion before we knew exactly what was wrong).
It is now a $600-800 dollar mistake....I only paid them $1800 for this job.
In b4 Mike ends up paying over 5Gs for a simple forged 347.
CURSE ME FOR NOT DRIVING THE 200 MILES TO ANDY. That would have been a minor inconvenience but it would have been done right. Yay I am now a cautionary tale. Learn from my mistake...go to only people you know and trust.
