I've got an 88 GL wagon with a newer engine from one of those import used engines from Japan deals. It's always had intermittent valvetrain noise. It's been getting worse lately so I replaced the oil pump. Didn't fix it.
What next to look at? I read on one manual about air getting into the oil system through a leaking oil pump gasket and causing the hydraulic valve lash adjuster(s) to collapse for a bit. Is there another place for air to enter the system? The suction tube in the oil pan? I haven't looked at that in a manual so I don't know how that is put together.
The noise seems to always be coming from the same side (right) of the engine.
Do I start replacing valve lash adjusters?
Really not wanting to throw money at the car. The pump, gaskets, new timing belts cost me plenty.

my engine in my 85 wagon had the valve train tick till i put two quarts of MMO and filled the rest up with 20w-50 on a NAPA Silver (AKA Wix) oil filter. the tick stoped the next day and never came back.

Craz, do you think a 10w30 synth blend is too thin to use in conjunction with the Marvels Mystery oil? What is it in this stuff that would quiet down the valvetrain? Seems like going thinner would make the noise worse.
Ive never tried MMO; always been afraid to run anything other than clean oil after a "motor-flush-gone-bad" experience I had in my beloved first car (an old Dodge Charger).

I just happened to remember that someone on the board once posted to try a product called "Seafoam" and to put 1/3 in the crank case, 1/3 in the fuel tank and save 1/3 for the next oil change. I just happened to find Seafoam at my local NAPA and i figured i had nothing to loose on a car than has 147,000 miles on the clock!...I walked right out of the NAPA store (spending $6.00 on the seafoam) and poured some in my crankcase....the next day NO ticking at all...honestly the best $6.00 bucks i have ever spent!...
