The next time you do an oil change, put a liter of tranny fluid in with the oil BEFORE you change it. Let it run for an hour or two.The tranny fluid will clean out the gunk that causes your lifters to stick.Now do your oil change. Do this each time you change your oil, only use a 1/2 liter each time. You will be amazed at the difference, I was.

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.

What you want to do is find a shop that sells BG products. Ask them for part number 210 (engine flush) & part number 110 (MOA ((motor oil additive)) ) . First install the oil flush and moa into your oil filler and run motor for 30 min AT IDLE. Now drain the oil from the crank case and install new filter and castrol 5w30 non synthetic oil. Then run the motor for 15 minutes AT IDLE. Now drain that oil and install new filter. Now goto part store and get MOBIL 1 0w30 and preferably a factory GM oil filter. Install the oil and filter and put one more can of MOA into crankcase. We do this service at our shop ($250). You can do it for about $70. We suggest always using mobile 1 , it is a far superior product. The 0w40 takes no time to get to the lifter upon start up since its so light. once you reach operating temp the viscosity is factory...good luck

I am not an expert on the these engines but the 94 galant (in the USA) had a 4g64 engine (2.4 inline 4 cyl fuel injected). On the 4g64 engine the valves are hydrolic meaning there is no manual adjustment. YOur mechanic made a mistake in that the valve lash adjusters should have been reinstalled back in their original position. Being that was not done there is not much you can do other than replace them with new ones. By the way the valve lash adjusters should be partialy filled with oil so there is little or no plunger action when the adjuster is depressed. Your mechanic should have placed them in a can of clean engine oil and depressed the plunger on the valve lash adjusters to cause them to fill with oil. If you can still depress the adjusted after it is filled with oil then it is defective. By the way, this is not an unusual problem as many high mileage Galants make a fair bit of valve noise. You can get more details from a Haynes manual (about $20 at autozone)
