Gbranham's MkIV 427/IRS/TKX Build Thread...Spark Plug Shenanigans

[gbranham]

Been driving quite a bit, and have almost 700 miles on the car. Running great! The last month or two, I've only driven on the weekends, and I've noticed, come Friday after the car has sat for 5 days, I have a half-dollar sized coolant puddle on the shop floor. Its roughly under the front corner of the passenger cylinder head. I have no leaks while driving or for hours after a drive. I spent some time diagnosing today, and found the leak is from the front corner of the intake manifold gasket. I put a socket on my ARP 12pt stud nuts for the manifold, and low and behold, the entire passenger side nuts were barely better than finger tight. Driver's side was fine. I retorqued them after several heat cycles, but then drove 700 miles without checking them. Guess I should have. Anyway, the leak is gone, and Im glad I used Gasgacinch on those gaskets, or I might have had a real mess on my hands. Folks, don't forget to torque those bolts a few times in the first few hundred miles. I thought I did mine enough, but guess not.
