Removing sludge?
My LQ4 I picked up a couple months back has a crap load of dry sludge in the lifter trays and I'm sure it's made it's way into other places. How do you clean the block internally? There is still minor crosshatching and the tols of the pistons don't have much carbon buildup. A look at the plugs it came with show they're in normal condition. Is this just from a lack of maintenance and just sitting for years?
Can I just clean up the sludge and put in a new oil pump and lifters? Or a rering and bearings is recommended ?

If you are taking it that far it's only a little more work to strip it to the bare block, have it vatted, new core plugs, light dingle berry hone, new rings and bearings, then you are sure it is clean and good for several thousand more milews
