Model Years Affected: 2003, 2004, 2005, 2006

Engines Affected: 2.3L 4 Cylinder, 3.0L V6

Average Mileage: 95,556 mi (46,000 mi - 200,000 mi)


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.
