Most of my cars have magnetic oil drain plugs in them. This is one of those small items that can't hurt you and just might be a big help if it traps some metallic particles and alerts you to a small problem (before it becomes a big problem).
So when I removed the break-in Valvoline 30 wt oil from my DRM 368 motor to replace it with Mobil1 10W-30, I thought it would be a good idea to change out the factory non-magnetic drain plug for a magnetic plug. I found out two things: the ZR1 oil drain plug is a pretty unique item and nobody seems to stock or even make a magnetic drain plug for the LT5 motor. I suspect damaged or lost drain plugs can only be replaced by the Chevy dealer. None of the auto parts places that I checked (NAPA, Pep Boys, Autozone, World AutoParts) had a listing for any drain plugs to fit the LT5 motor.
Does anyone know of an aftermarket magnetic drain plug for the LT5 motor? If not, I plan on epoxying one of those super strong neodymium magnets into a new LT5 standard drain plug and creating my own magnetic particle attractor.
BTW, my oil pressure with the Mobil1 oil at oil operating temperatures (185 plus) seems to have increased about by about 5psi at both idle and at speed.
My idle pressure is now 40 psi and my pressure at 2000 rpm cruise is about 65 psi. Prior to changing the oil yesterday, I thought the Mobil1 pressures might be a bit lower than the single weight Valvoline oil. How do these pressures compare to other LT5 motors with synthetic oil in them?
I am using a new Bosch 3401 oil filter in this motor, but plan to switch to a Hastings synthetic media or Motorcraft synthetic media filter, if I can find one that fits the LT5. If not, I may switch to the pricey Mobil1 filter (MI-207). These Mobil1 filters go out the door here in Fire Diego at $12!!
