    Hi guys,

    Is there any way to inspect hydraulic lifters?
    I think I might have a sticky one and don't want to replace them all.
    Its on a AMK motor with 100 000km.

    It is possible to dismantle them. It involves a couple pieces of wood and good firm hit. There are guides on the net, have a google bud.

    When I start the car I got the chain rattle noise from the head, so after some diagnoses I replaced the cam chain tensioner, The noise is still there.

    I have also replaced the cam position sensor and did a sump service last night, noise is still there, between 1400rpm and 2000rpm when blipping the throttle.

    ah, yeah i was going to suggest the cam chain tensioner. I had this a couple of weeks ago and suspected tappets at first but turned out to be the cam chain tensioner. Although a single tappet would have been far cheaper :(

    Agreed.
    I am stumped at the moment, was hoping to find sludge or a blocked oil pick up, but alas none of that, motor is very healthy looking for 100 000km

    i think there is an official method of checking the tappets without having to take them all out - think i saw it on elsawin when i was having issues with mine. I'll see if i can find it when i get back from work if it'll be any help

    100.000km isnt alot of miles.

    what can you do to tappets in taking them apart? theyre a very simple part arent they?

    Ive seen them taken apart and cleaned, but tbh the best way is to reset them, take them out wind the tappet back in a vice, tighten up back off until the tappet is spongey refit, start engine and they will rest them selfs

    did you change the chain itself as this could be causing the rattle?

    me? mines fixed - as i said turned out to be the cam chain tensioner. The fine piece of gauze that filters the oil before entering the tensioner broke and ended up entering the oil passageways and blocking the mechanism. Replaced the tensioner and it sounds fine now. Didn't replace the chain
