Oil plug pin hole I replaced the oil plugs in the front of the engine and there are two plugs with a very tiny hole that sprays oil on the timing chain. The new plugs don't have the hole so I had to drill it out. The smallest drill bit I have is 0.040. It is slighly larger than the stock size. Will I have any oil pressure issues with the larger hole? I figured the high pressure oil pump will make up for the loss. What do you guys think?

Yeh I went to the dealership and found out the part number. Your right, it is 0.025".
I found some drill bits that will go down to 0.025 but my machine shop said they go a little larger than stock most of the time. Hopefully he is right.

You will lose pressure out larger oil hole orfice. A high pressure pump has <10psi at idle you will lower your oil pressure.
I would DEFINATELY use a drill <.025" the oil is used to oil the chain and gear it can live with less, more will hurt more than it helps.
Good luck
