What's the general consensus?
I hear stats like "[significant number]% of wear is on cold startup"; my general understanding is that this is from cranking to equilibrium temperature - i.e. 20 minutes or more.
How much of this wear can be mitigated from the first few revolutions via the use of a prelube pump?
Also, are OEM oil pumps typically installed with an internal check valve to prevent backwards flow/damage from the new oil pump?
Are there any scientific articles on the topic? I see one poster's S2000 with a good wearing engine, albeit with a bypass.
I have a car which I am just having fun with so I don't mind doing the work at all (in fact I would enjoy the project), but just doing my homework first.
