I'm plagued with low lube oil pressure on my '97 E350.
Done a fair bit of diagnostics already. Minimal results. Oil pressure is currently 5psi at the hpop reservoir, and 10psi at the block with a new Melling pump. This is after letting it idle for 5-10 mins from being dead cold.
I have confirmed that I have the revised cooler/filter header with the snap-rings on the bypass and relief valves.
The few other possibilities I have read about are:
- oil pump pickup (drawing air i.e. cracked, bad gasket, etc)
- stuck/faulty bypass valve (however unlikely with my snap-ringed header)
- wiped out thrust bearings (ballooned torque converter)
Who's got ideas how to isolate this further?
