Fresh carnage!
This comes up at least every other month or so.
As I dutifully say damn near every time, all those drip tabs, bolts with holes in them and all that other junk were used because they were the cheapest way to try and get to the end of the warranty.
Drilling a hole in the plate is the most efficient, inexpensive way to get full pressure oil onto the timing set.
It’s even more critical with a gear drive.
Always searching for new info, I'm wondering what symptoms of lack of lubrication to the timing set is showing.
We've built the BBlks and Hemisback in the day, had a 340 Barracuda running 2/10s off the NHRA record.
Lotsa really stout street engines with UBER valve springs.
We also build, repair vehicles that are Daily Drivers, that rack up 10 - 15,000 miles a year, year after year, scrutinize, refresh them later in
life.
Our race engines, straight, or roundy-roundy very high output, low miles, no timing gear/chain issues.
Our street engines less high output in most cases, go 10s of thousands of miles for years, not a few races, and we've never seen an issue in the timing gear other than normal wear, or the plastic breaks off.
My mentor taught me bunchas stuff, he was our local track tech inspector, and represented his Province in the highly regarded Plymouth Challenge.
What were we missing, respectfully?
What was it you saw in wear or heat that we missed.
Thank-you .
