No.
Don't drill a hole either. You dont need pressurized oil to the chain and imo you certainly don't wanna take any away from the main bearings.
Buy a roller chain and itll have plenty of oilling from leakage around front cam bearing and stop in go from crank oil slinger. Run the bolt & plate with the hole or drill a hole in the bolt for valley drip as well.
Tensioner can do well. I've run one for years. Not a have to, but not a shouldn't do either.
Never in a million years would have thought I'd be reading people saying to pull oil from the main galley.:eek:
There is no need for all this over thinking bs for the timing chain. Ridiculous. Never heard this crap before till this site. Jmo
