While I have the timing cover off to tab the KDP on my 96 I was thinking of looking at the oil pump. I have read conflicting information about there possibly being a higher flow rate pump in the 24 valve engines that will fit in the 12 valve engines. I know the idle oil pressure is higher on my 98.5 than my 96 (which is still good according to the specs). On one supplier’s site I saw different part numbers for the two pumps but the picture of the 12 valve pump had the part number of the 24 valve pump on its casting.

Are they all the same? Do some people only stock the newer pump for all models?

I don’t want to pump my oil to death but higher mass flow rate of oil on a hot engine might be a good thing.

Two weeks have passed since my original post on this subject and no one knows or has wondered the same thing?
