Can the tappets be adjusted on a Hyundia Tucson 4 x 4 V6 ,2.7 petrol engine?


Not normally, if they are noisy you can try a heavier oil in the engine.

A 10-40 vrs a 10-30 and change the oil at 5000k religiously.

or you add an oil additive to knock down the noise.

eventually you will have to replace the tappets.
you may want to pull the valve covers and verify all valve rockers are torqued correctly -- looseness hear can create noise.

06 A6 pet 2.0T very loud engine noise at bulk-head side of rocker


ur car uses hydrolic lifters instead of tappets but they sound the same when faulty. most likely a 'sticky' lifter. very expensive to change.

96 Eclipse 2.0 non-turbo Engine has a tapping sound that sounds like its coming from the top of the engine. The sound is loud enough to make it difficult to tell where its coming from. I took the valve...


Most likely cause is a hydralic tappet. Mits are well know for top end noise. Note we are talking about a tapping or clicking sound not a knock. You can try using an engine flush product if the noise is getting bad and then changing your oil. Generally if the oil is not changed regularily eventually the tapping noise gets happens.

2003 Ford Ranger ticking noise, not a ping or knock. It is coming from the engine.


THE ticking noise coming from the engine ..is it just a 1 tick on idle at about each rev of engine,,and does it make any differance to the running of engine ,,Does it get softer when it gets warmer.
As it sounds like a loose tappet and being a oil adjusted tappets this thought of thing does come in now and again. and the best thing to do is to get a small plastic tube 25mm (or 1' ) and 2ft long and put it to your ear and listen at the top of the rocker cover ans see if the noise gets louder in a certen place ,as you will hear it if it is there..
Other wise it could be a Small end on the conrod which the piston is connected to.... lets hope not.
So let me know as soon as poss the answers to all the above. Ron

1997 nissan pickup 4wd, just had timing chain replaced , now have noticeable knocking noise coming from valve cover ? mechanic says need new stack shims on valve rockers ?


Not likely. You have a 4 cyl engine with over head cam. It has hydrolic lifters. If it wasn't making the noise before he replaced the chain, then its something he did...or didn't do. If it was making the noise before, most common reason would be 1 or more lifters not pumping up. If you have a six cyl, no one changed the timing chain, (It doesn't have one!) The 3.0 6cyl has a belt.

Knocking noice


does that sound get faster when you press the pedal. make sure that you have enough oil in your car. also make sure that you have to correct weight oil. if it's to thin, it can cause this.

Loud ticking/knocking/rattling sound when I start/accelerate


hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456
