So, while I wait for my xj head to come back from the machine shop I removed oil pan.

Pics are of oil pickup, lifter, top of short block

I thought it looked horrible and figured it meant I should replace both the pickup and pump, (yes, I have bad oil pressure, yes I know it well could be something else), but taking this one piece on its own...even if the low oil pressure was a result of something else, would you replace?

That screen looks pretty packed off. Either get new one or clean that one up.

damn son. no wonder you had low oil pressure. I'd find the source of that gunk first. and count ok it being in the passages. after installing new stuff run it a cpl hrs and pull the pan again. the screen will prob have more gunk in it.

I just picked this XJ up a few weeks ago. have only put a few hundred on it myself. Everything is gunked. Don't know if they just never changed oil or put some sort of "sealer" product or something in it. Rocker/pivots were very worn, fortunately they look great on the replacement head I'm putting on it

Things were so gunky up top I figured I need to take a peek down below.

From other threads, I've seen that if you remove the oil pump to inspect/clean whatever you may as well buy new due to the fact you can't buy the gasket separate from the pump. Is a new gasket pretty likely/always/rarely needed?

I also saw on that said if you remove the pickup you need some sort of new sealer or feeder tube or something to keep that junction air/fluid tight.

Anyone have the same/different experience?

Aljay

You can make your own gasket.

You CAN buy thegasket.

The pickup needs to be pressed into th new pump. No sealer.

I've seen much worse engines cleaup nicley with Rotella, Marvel Mystery Oil, and a Napa Gold filter.

If you're talking about the gasket between the pump and the block, The OEM part number is J3172332.

You'll probably destroy the pickup tube trying to remove it from the pump. Leave it be. Putting a new one on requires a special tool.

You can try this: Soak the screen end of the pickup tube in a bucket of mineral spirits until the crap loosens up, then see if you can get it out using a stiff bristle paint brush. To flush the pump out, chuck up the oil pump drive in an electric drill then submerge the pickup screen in a bucket containing 2 quarts of new motor oil. Run the electric drill clockwise to circulate the new oil through the pump. Repeat as required using new oil to get all the nasties out of the pump.

If you decide to get a new pump, autozone has melling pumps. Get the STANDARD pump, not the high volume pump. You'll need to buy the pickup tube seperate, then find the tube installation tube (Melling) to install it.

Thanks CCKen, sounds like the plan!

Error in my previous post. Its a tube installation TOOL, not a tube.

Go to Melling's web site. There's videos on how to install a tube, and preoil the engine. Check it out. There's also Youtube vids on preoiling an oil pump, which you have to do.
