Hi all. My sports wagon has the dredded tappet rattle, but this 1 seems a bit strange.
It has 347,000 on the clock,but I think the engine might have been out at some time as it uses no water and has no oil leaks. burns no oil. I change the oil and filter 4 times a year. Prob overkill. starts and runs fine.

The tappets will rattle so loud you need earplugs to stop you going mad. This might go on for weeks, then all of a sudden (this can happen on start up or while driving) the rattle just stops. Beautiful for a day or maybe a week, then off it goes again. I am presently using Shell Helix 25/60 with 2 small bottles of STP oil treatment.

Also would using a genuine Subi oil filter help?

Thanks all

try adjusting the timing belts so they are properly tensioned 99.9999999% of the members here swear by that

Thanks Toonga

Apart from the cam belt covers, what else do I need to take off to do this, also do I need to loosen the main crank bolt ?

Cheers

the procedure is in this document

also people say to renew oil pump seals, I'd be reading oil pressure first and after. At 347,000 km a new set would be not a bad idea. Seen in US for $15 ea , need 8, remove pulley, timing belts, cam boxes clean up their sealant grooves and some patience

You don't have to remove the belt covers to reset the belt tensioners .
The middle one has two rubber double plugs and these give you access to the pair of bolts that hold each tensioner in place . You undo them enough to let the tensioners springs take up any slack and then torque them to the factory spec . Then replace the rubber plugs .

If I read it right the factory WSM suggests having the outer belt covers off and applying 17-19 ft/lbs of torque to the cam pulley bolts to pretension the straight side of each belt before resetting its tensioner .
From memory I just turned the engine over via its crank pulley bolt and reset the tensioners . This was not too long after everything was rebuilt and to allow for a small amount of stretch in new belts . It did run quieter afterwards .

DO NOT overtighten the tensioner bolts !!!!! Common stuffup and buggered threads in aluminium hard to fix - in that location .

Some would also say to replace the EA82 part in the engine bay with an EJ20 or EJ22 part... That gets rid of the lifter tick and places a on the driver
