Jim H post reminded me of a strange issue we once had that involved a strange ticking sound in our 455. We were out in the middle of almost no where going to Alaska when the ticking started. In the next town we came to we stopped at a side of the road truck and auto repair place to have them listen and guess what the cause might be. Ears, stethoscopes and a lot of hmmming produced nothing definitive. While there I pulled the oil dip stick and noticed the oil level was way high. That sent us off looking for a blown he’d gasket or some other leak of water into the oil - only there was no brown foam that would suggest water in the oil. After much puttering and speculating I found that the dip stick tube had been pushed down into the block (no bulge in it, just straight tubing that slowly slid into the block casting! That caused the dip stick to protrude too far into the oil pool and read high. It also allowed the dip stick to protrude too far down where a crank lobe was just touching it causing the tick sound. So, anything is possible with our old girls.......

The backfiring, however, persisted, accompanied by a mechanical
clicking sound. So, I referred them to a local repair shop for a
compression test and further repairs.
