What does your oil pressure run at? Cold vs. fully up to temp?

    my presure gauge reads about 300Kpa at idle, up to about 400kpa (kilopascals)

    Im not sure what that is in pounds lol

    Does synthetic oil tend to drop the pressure readings? At temp I'm 42psi WOT, 32psi cruising ane 20 psi idle. Running a Texas Speed 6.7L stroker with high capacity oil pump. Original engine got eaten by Castec heads leaking coolant into the oil and melting the cam bearings.

    My experience with synthetic versus conventional (comparing same weight and brand) is that the pressures remain more consistent warm or cold with synthetic. The conventional seems to thin out a lot more when heated so the average pressures are noticeably lower.


    Has your pressure always averaged these numbers with the stroker or did it suddenly change?

    I’m in the middle of a tear down trying to figure out what’s going on. Found a broken spark plug, 7 melted and several burned exhaust valves. Figured out the plugs were counterfeit ACDelco. Sheeeettt...

    There is so much counterfeit junk out there these days. I bought injectors for mine on Rock Auto listed as "wholesale closeout" which I have bought before and seemed real but I got them and they just didn't look quite right. So I returned them, lost shipping both ways (which I don't agree with), and paid over $100 more to order real ones.

    I wish... saved nothing (paid full price) and got $4,500 worth of damage. Ordered a long list of parts for 200k mile service. All fluids/filters/injectors/sensors.... Missed that the plugs came from Amazon Marketplace vendor, not Amazon. It snuck in under Prime shipping making it harder to catch. Some AHole made 20 bucks or so and gave me a huge mess to clean up.
