I had to retorque the heads on the 6.6L Z28 motor while it's out for a catastrophic oil pump failure, when the mounting boss broke off of the motor on the rear main bearing cap. The part left on the engine was still held on tight with its ARP stud, but the pump just plain ass BROKE. I hadn't seen it before in my 45 years of doing this, so we upgraded!
"Stay tuned" for the updates coming SOON and thanks for tagging along! 👍
