  There's a new project update for you this morning. GRM advertising sales ninja Steve C. is making some more progress with his sick Camaro.

  If you're into post-failure analysis of engine parts, you'll definitely want to check it out.

  Yup wheel bearing shell came apart.. I'm fairly certain that the tie bar snapped at 6800 rpm. That's the part that keeps each I/E roller lifter pair from rotating in its bore. Once a lifter rotates, it ceases to roll. 20% of the roller wheel had worn away. Then the wheel failed. A lot.

  That tie bar looks like a real weak point in the design of the roller lifter.

  there are thousands of engines out there with aftermarket roller lifters with tie bars that run for a long time without any problems. but like anything else mechanical, failures do happen.

  Agreed. No complaints here. That lifter survived seven years of 6800 rpm without so much as a whimper.

  Poor little lifter.

  didn't know they used wheel bearings in engines.
