How do you diagnose a lifter that should be replaced before this happens?

It starts with a ticking sound.. Like any noise, it isn't good.

Ultrasonic machines are required to work with these engines… You'll never remove the debris without one. Best purchases we ever made, I outfitted every building with one.

I readily admit that my engine had a noisy lifter for quite awhile (as Jake quickly concluded from the failure evidence).

Is there a recommended course of action for a noisy lifter? How long? How loud? Under what circumstances is opening up the engine warranted?

Well, it could have been much worse. Glad to see she is repairable and 136K with nearly 100 track days might be a new record for durability. Should be much quicker after you slip those 3.6L pistons and sleeves in there.

Hey brother! I thought that we were keeping the "3.6 thing" just between you and me? There might be a few PCA Stewards on this site and I need to keep this on the lowdown.

In all seriousness, the engine will be rebuilt ALL STOCK except where allowed to deviate by the Boster Spec rules (such as the replacement IMS bearing) to the extent that I could pass an engine teardown inspection if something that drastic was ever needed.

However, I am taking advantage of the downtime while the engine is being rebuilt to further reduce weight in the car. If my calulations are right, when its all re-assembled I should be able to manage the car to min spec weight by adjusting the fuel load.

New engine + min weight = no excuses.

If one is going big bore on a rebuild....what is the cost of waiting for the failure to occur vs addressing it premptively? You would be incurring a lot of labour twice....weight that against collateral damage that can occur.

I ask as I have an intermittent lifter tick (or so it sounds)....usually shows up after the car is idle for a time and then disappears when the car is used regularly
