Mazda Mazda6 Ticking Noise From Engine Due to Sticking Valve Lash Adjusters

(40 reports)

A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

I have been told I need a new engine. So it sits in my driveway for now. It needed an oil change before I went on vaca came home and my sister used it. The next day it sounded so loud like putting a card in the spokes on a bike. I am trying to figure out if it really is the engine?? -

I've just started to hear a tapping "ticking" noise from the top end of my 2.3 liter. I have decided to fix it all myself. upon removing the spark plugs, I discovered the culprit of my oil consumption, a blown head gasket! In the coming days and possibly weeks (don't have a ton of free time to work on it) I will proceed to remove the cylinder head from the car and plan to replace the head gasket and the hydraulic bucket valve lifters in the process. Hell, I might even have the head ported and polished!! This problem has been explained to me as having faulty/dirty valve lifters - we shall see. -
ticking noise from back of engine comes and gos sound like popcorn cooking at times -
There's a loud ticking noise of the top of the engine. -
check intake manifold runner control. use stethescope on engine and intake, if louder on intake then that's the problem. Or disconnect IMRC valve and if it goes away then that's it. -
i believe that tapping noise is coming from a lack of oil pressure i rebuild my motor new oil pump and timming chain kit i bet it will fix your problem. or take it to the dealer and pay with your arm lol your timming is bad . -
loud ticking from engine, is not continuous seems to go away under acceleration. i'm going to pull valve cover and inspect. i know the mazda pickup motor used from 88 to 93 2.2l had a hyd. lifter in end of rocker arm and they would wear out a hole in the end of lifter. i figured they learned something from those motors, but maybe not. thanks for info. -
My engine has made a ticking noise (louder when cold) since I bought it at 42,000 miles, and I have kept the oil regularly changed. I've narrowed the problem down to this. -
Slight ticking as I accelerate.. and vehicle takes two turns of key to start -

My 2005 Mazda 6 4cyl 2.3L deveopled a loud ticking noise in the engine , due to lack of oil. WhichI could not figure out how it did not hvae oil. The noise got louder 1 day ( 10/29/12 ) & was on my way to drop the car at the mechanic & the engine blew. Now I need a new engine & reading about all the problems it might not be worth the 5-6K to fix it since it may happen again with a new engine. Use to love Mazda. NEVER WILL I BUY ONE AGAIN! -
