as they are hydulic you should not have to adjust them,if they are rattling,it's usually due to poor oil change history,try engine flush and you may have to remove sump afterwoods if the gunk blocks up the oil pickup,filters block and unfiltered oil then circulates throughout engine and makes lifters noisy,to check hyd lifters you need a "bleed down bar"to compress lifter and measure gap between rocker and valve,if it does have adjustable rockers then it's done with engine idleing with rocker cover off ,back off nut till it rattles,thentighen it down till it stops and then 1/4 more turn

SOUND'S LIKE YOU COULD HAVE A BAD ROD OR CRANK OR LIFTER.TRY THIS CHECK YOUR WATER AND OIL NOW START THE ENGINE IF IT IS A FAST KNOCKING HOLD YOUR FOOT ON THE BRAKE AND PUT THE CARE IN GEAR IF IT QUEITS YOU HAVE BAD ROD SERIOUS MOTOR REPAIR INTERNAL.DO THE SAME THING AGAIN AND IF IT IS MORE A THUMPING NOISE AND A SLOW DEEP KNOCK THEN WITH THE ENGINE IDLEING PUT IT IN GEAR HOLD THE BRAKE GIVE IT A LITTLE GAS AND IF THE MOTOR KNOCK'S GET'S QUEIT IT'S POSSIBLY THE CRANKSHAFT ANOTHER INTERNAL PROBLEM MOTOR OVERHAUL IF IT'S A FAST RATTLING IT'S PROBABLY A LIFTER STUCK OR BLEED DOWN DIRTY OIL OR A WEAK OIL PUMP ALL ARE BAD NEWS SORRY.GOOD LUCK

Bad lifter can cause poor idle. Make sure oil is new and full and that oil pressure is good. If all that is good and tapping continues, replace bad lifters.

it could be a wrist pin, and im not sure if those amc's had hydraulic lifters but sometimes with old lifters when the oil pressure is lower at an idle the lifters arnt filling up all the way so they develope a little valve lash, and when the rpms are raised the oil pressure raises and fills the lifters. you could try chasing the noise down with an automotive stethoscope.

You should have hydraulic lifters, unless someone changed them along the way. Normally nobody puts solid lifters in a vehicle that is a driven on the street daily. That being said, the normal adjustment for hydraulic lifters is normally take all clearance out of rocker arm to lifter plus an extra 1/2 to 3/4 turn. I used to do this with the motor running, I would adjust it tighter till it quits rattling and then tighten an extra 1/2 turn. If the lifters are bad, however, the rattling will never go away. I hope this helps.

I dont think and intake gasket will cause lifter noise. It may cause a rough idle and or a miss at idle on cold start up . as the engine warms up the miss or rough idle will decrease . As for the lifter noise this could be cause by the lifter bleeding down or poor oil presure . On your model of engine there is no adjustment on the rocker arms for lifter noise . They are a 0 lash type .

The 1.6 has hydraulic non adjustable lifters and that lifter tick has been a thorn in their side ever since the 1.6's inception.
The way to eliminate the noise is of course replace the lifter/lifters use a cam lube on the lifters bottom and let the new lifters soak in an oil can overnight.
Check for bent push rods when you have it opened up, R&R valve cover,R&R rockers R&R pushrods, Remove and Replace the lifters.

WOW you never made a mistake MR TOYOTA ????

It seems your just lurking in old posts to stir up trouble.

And for you information that engine does have lifters (more correctly called CAM Followers, but they are a type of hydraulic lifter.

the lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.
