Try using an oil additive designed to loosen tappets with your next oil change. Maybe a change of oil brand can help. Changing out the offending tappet is the ultimate repair, but most expensive.

Light ticking noise in engine in 2009 dodge journey RT V6.


Ours was doing the same thing until I switched over to full synthetic oil. It does still tick on startup if it is colder than -10 degrees Celsius and it is not plugged in. If you figure anything out please let me know.

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.

Engine noise when starts


Sounds like you need to run a thinner oil maybe. The oil is not pressurizing the engine components quickly and you hear was is called engine tappets. The rockers on some cars have what are called hydraulic lifters. They fill with oil after startup and then the sound goes away. You may think about having the lifters replaced soon, which are not too expensive. Be sure your vehicle has hydraulic lifters also. If your mechanic is any good he will know if it does or not. He maybe waiting for it to cause engine damage also, and knowing you will return to him to have it repaired also. Be careful.

Does a 1999 frod contour have hydraulic lifters or mechanical lifters


Both the 2.0 liter 4-cylinder, and the 2.5 liter V6 are overhead cam engines. While all years of the V6 us hydraulic tappets, the 4-cylinder engines varied. From 1998 and earlier, they had hydraulic tappets. From 1999 on, they used shimmed mechanical tappets. Adjusting valve clearance on the later engines is a little involved, and, if you're not familiar with the procedure, it is perhaps best left to a professional mechanic who is familiar with the engine.

Ticking Noise at Startup


Possibly a leaking hydraulic lifter. They can leak down while engine isn't running and then make a ticking noise for a while on startup. If it takes 10-15 minutes to go away, it is more likely to be a loose tappet which needs adjusting.

Noisy startup when cold, sounds like valve


Hello onarock844...The Hyundai 2.4 litre and the 3.3 litre are known to have valve train noise. Some sooner than others.
The timing chain tensioners on the 06 and 07 Sonata 3.3 engines built before August 4, 2006 are well known for developing wear that allows them to make a tapping or rattling noise for a short time after a cold start. This noise can be mistaken for a lifter noise, although the actual source is in the front cover area of the engine. Hyundai has released a technical service bulletin on this problem, which describes installation of an updated design timing chain tensioner (part #24410-3C300) to correct this noise issue.
Ask your dealer to refer to Hyundai service bulletin #06-20-002 for information...If this has already been corrected,,,and the noise is coming from the upper engine area and not from the timing chain area, then the valve clearance will need to be adjusted. This is done by disassembling the valve train and installing slightly different size tappets to change clearance.
This is a fairly labor intensive process, so if you are still under factory warranty then you will want to go over the dealer's head and get the Hyundai zone rep involved to get it covered before your warranty coverage expires...
I recommend useing a full synthetic engine oil, i know in a few cases where the noise has stopped when the oil was changed over to synthenic, also a high quality filter is important, such as a purolator.
Good luck...i hope this helps...please rate me a fixya.
