Oh and replacing oil pump isn't an easy job, it is possible to do it in the car but it's a MAJOR fk around, you need an engine brace to hold the engine from the top and then drop the whole subframe off, sump off, pistons off, crank out. Oh gearbox has to come out and clutch/flywheel off before you can get the crank out. Really, it's a whole motor out job.
