So my 240 has low oil pressure at hot idle. Kent's "Diesel Performance Tuning and Repair" says that this is caused by either worn oil pump gears or crank bearings.
I am currently unemployed so I'd like to try to fix this without a mechanic, but I love my car and I don't want to risk f*cking something up royally and ruining it. Would this be the kind of thing I would be able to do myself? I can already do basic stuff like changing oil and I've installed the glow plug relay manual override so I have some pretty basic experience.
I don't have a lift, only ramps, will those suffice?
How can I tell if the problem is the oil pump gears or the crank bearings? Is one harder to fix than the other?
Thanks in advance,
Grey Kingsley
