How could this happen
About a year ago, I pulled my motor on my 68ss 396 Elco for a 4 speed conversion. It took some time, I posted a thread on it and the car ran great when completed. However, my main seal was leaking in the rear and I feared it had contaminated the clutch. So I decided to drive it until it was undrivable, pull the motor and fix it. The motor had about 6 k miles on it now coupled with a Jody M23w. Shortly after, during an easy cruise, I heard a BANG in the motor. It rattled for a moment then went away. I drove it home gingerly and when I got home, started it again... same BANG. So I shut it down and decided it was motor pulling time.
Got the engine to the original builder, Jim Larr. Jim Disassembled and found a part in the cylinder that we couldnít identify. I didnít have the air cleaner off for over 1 k miles, where did it come from? Turns out the mesh screen and base from the air cleaner had come loose, got sucked in thru the big quadrajet secondaries and into the intake. No idea how long it had been working itís way into the cylinder. Bad design Chevrolet!
A word of caution for those using this set up....it can happen.
By the way, Jim went thru the motor for me and fixed the damage, my auto tech forged pistons won the battle and were massaged and damage free. Replaced the bearings, rings, valve job to clean up the seats, rear seal fixed. Fired it up on a stand. No leaks and now I got to install it today.
For any So Cal people looking for a seasoned builder . Jim knows his stuff and after recovering from his illness, he operates a full shop in a building built on his property. He knows all engines but is really good at Chevy iron: rats, mouse and LS motors. Heís a good dude looking to rebuild his business . Jim Laar aka Engine Jim 760 561-2226
