Just a thought...Replace the oil filter with a quality filter and see if it helps.

at wat mileage is it recommended to replace the oil pump?
Almost never. If the engine is run with clean oil, it would be rare that a factory Toyota oil pump would wear out. A spun bearing (nasty noises) or a lazy pressure sending switch is more likely.

That is because more than likely your oil filter does not have an anti-drain back valve to allow oil pressure to build up quickly which leads to premature timing chain component failure,read below:

Most engine wear on any engine occurs at startup with that said the R series Toyota engines such as the 18R,20R and 22R all use a timing chain which it's tension is supplied by hydraulically driven timing chain tensioner which has it's oil pressure buid up few seconds after the engine has started therefore the timing chain rubs on the driver's side brown colored nylon/plastic timing chain dampener or guide and after so many miles (140-170 000 miles in the city with the average 4 starts per day) the driver's side guide breaks through causing the chain to rub on the timing chain cover for the first few seconds upon startup and when driving in fifth gear and letting off the gas.

Usually by this point the other timing components such as the camshaft sprocket,crankshaft sprocket and chain have their specs out of tolerance and hence must be replaced as well.The tensioner sometimes sticks due to dirt build up and other problems arise as well and must be replaced as well,all of those parts are sold in the aftermarket world as a "timing chain kit" which also include gaskets and a front oil crankshaft seal.

Toyota on the other for some reason does not sell the parts as a kit but as individual parts which would cost around $400+ and from all of the reading I have done on many Toyota 4-Runner/pickup discussion sites I have come to the conclusion that many experienced off-roaders who cannot afford to buy all of the genuine Toyota timing parts instead buy the chain and tensioner from Toyota and the other parts from aftermarket as a kit but of course don't use the aftermarket chain or tensioner.

The best brand of aftermarket timing chain parts to use on the 20R & 22R series Toyota motors are:

http://www.autotoyotaparts.com/toyota-truck-parts.html
http://www.toyota-engine-parts.com/
http://www.europeanautomotive.com


and if you choose to buy from Toyota these places have the best prices in the USA & probably the whole world:

http://www.toyotadiscountparts.com (free shipping with $100 & up)
http://www.Toyotaparts4U.com
http://www.toyotaofplano.com

Other ways to check timing chain wear are:

you can also remove the valve cover and take a flashlight and see if the driver's side timing chain dampener or guide wore through.

Finally these sites explain the timing chain replacement well:

Your chain won't last long,you may destroy your timing chain cover and being an interferrence motor one,several or 8 valves will be bent when they hit the top of the pistons.
There are two timing chain lengths for the 22R series engines one for the long deck block (81-84) and one for the short deck block (85-95),I cannot remember the exact # of teeth for both timing chains but if your mechanic was honest he would of done his homework by going to the dealership or called around even he does not get discount from other part suppliers.
You should make him replace it for free.These sites below explain everything you ever wanted to know about the 20R & 22R series Toyota engines:
