High oil pressure 2000 Vortec 6.0 liter 200k mi
My well maintained 2000 Suburban 2500 with Vortec 6 liter and tow package has about 200,000 miles and is reading an oil pressure at the gauge around 70psi, which seems weirdly high to me. My mech says to count my blessing but I recently read about an oil regulator valve in the oil pump that can fail (usually failing in the closed position blocking flow) and I wondered if it may not be stuck wide open and if it might be an issue or a blessing. Or maybe just a faulty gauge?
It's my toy hauler that pulls our 10,000lb boat/trailer (below) so maybe high pressure is ok as my mech says??
Any thoughts would be great, especially positive ones saying it's a beautiful thing.
Thanks in advance, Mike
