oiling timing chain
All I know... is people who drill the galley plug for direct pressurized oiling off the main...the oil pissing out is hitting the cam sprocket and fanning off into the timing cover around it. Look at the shape of the cam sprocket and tell me the oil isn't just flying off. The chain itself at rpm is THROWING THE OIL OFF.
Ask yourself why they designed the roller chain. It works fine. Could you prove it doesn't ?
If people could see their ideas in motion/at work.. they might find it's for nothing.
You just made another internal oil leak.
Now the bolt with the hole, the lifters and rockers oil returning into the valley, dripping through that bolt down to the plate 'if it's not grabbed by windage'..hitting the drip tab and off that onto the chain.
The slinger is also fanning oil up and around as well as shielding the front seal from direct splash and keep it from leaking in short time.
You don't need direct pressure oiling and you couldn't aim it for **** without some messy pressure testing of it where you make an angled piss hole and cross your fingers it doesnt just hit and fly off the gear missing the chain all together. Nice thought..but pointless and unnecessary.
