Ok, this sounds like a weak fuel pump and clogged filter. if possible, you will need to change these two vital devices. I would also replace the air filter as well.
Inspect the injection system for faults as well. make sure all injectors are firing properly and on time. replace any injector that isn't functioning correctly.

Could be some debris in the oil pickup screen (can access it if you remove the oilpan) Or worse case scenario is your bearing is starting to fail...which is a BIG job (Removing the engine to repair it) 30 psi is the bare minimum for your engine to run safely without damage...so i see why your very concerned.
I hope its just a little "Gunk" on the screen. If it is i would consider putting some Seafoam (1/2 a can) into the engine oil and drive around like you normally would for a couple of days and then change the oil (Its a great product for breaking up "Gunk" in the oil or gas line.)
I hope this helps you out 8-)

SOURCE: lifter ticking
You may have a dirty lifter with varnish buildup. Try this as it may very well solve the problem. Purchase a can of Seafoam Motor Treatment. Add 1.5 oz of Seafoam for each quart of oil capacity. 4.5 Quarts = 6.75 oz Seafoam. Drive the car until you no longer hear the lifter and then have the oil/filter changed again. Next oil change use a quality filter such as Wix, Mopar, or Purolator. You can purchase Seafoam at almost any auto parts or marine store and at some Walmart stores. Here is their website. http://www.seafoamsales.com/

Most serious item I see is oil pressure. Put a mechanical gauge on the engine and get an accurate reading. Also make sure that the passage to the sender isn't blocked. If you did the pump yourself, did you find any coolant in the oil? In 99% of all low oil pressure situations, the oil pump has not failed. Rather, either a cam bearing or crank/rod bearing is worn. You do not have to have one spun or completely worn out bearing. Even wear of all bearings that is somewhat excessive can bleed off enough pressure to cause problems (plastigage the engine bearings to determine wear).
As far as coolant loss. A cylinder head gasket can fail between cylinders, into a water passage, into an oil passage or any combination of those and externally as well. The cylinder heads on engines beginning in about '98 are prone to "micro-cracking" which can lead to all kinds of hard to diagnose coolant loss problems. It may help if you have a shop do a dye test and a hydrocarbon test on the cooling system and see what they find.
I have seen several kinds of block sealing systems available. Though I generally do not recommend them, as the longevity of the repair isn't predictable, you could try that as a option of last resort.
There is no quick easy solution to your problem but with a bit of "poking around" you may be able to cure it. Don't bother repairing one problem before finding out what the other one is first though as together, it might be smarter to replace the engine.
