I'm blaming you pal ?????? try to locate the issue by having someone run the car out of gear ...whilst look have a look under the bonnet listening for it ... Simulate the conditions ..operate the Air con.. Engine running

Engine has hydraulic lifters. 1. Seals are wearing and oil is draining out while sitting. 2. oil is dirty and needs changed. 3. oil is low. 4. engine has sludge build up. Try "pass or don't pay" engine cleaner for smog test additive and follow cleaner directions.

When it starts to act up, take off the fuel cap and see what happens. Check the computer to see if there are any codes. Possible weak fuel pump. Check pressure with a gauge. Check fuel filter. Squeak noises are common. Look for the area the noise comes from and isolate the squeak.

It's a good idea. The filter keeps particles from the clutch plates from entering the valve body. The damaged valve body is expensive.

You might have an air lock in the fuel system. The lines from the injector pump possibly need broken loose at the injectors and cycle the fuel pump several times until nothing but pressurized fuel comes out.

You have to remove the transmission oil pan to access the transmission fluid filter. The bolts are turned counter clockwise to remove and clockwise to install (righty tighty, lefty loosey). The biggest problem you will have is the transmission oil leaking from the pan after you replace the transmission pan. Look up the details on proper installation of the pan. Also, check your manual (at local library) to see if their are going to be any obsticles you will have to remove that might be on top of the transmission pan or in the way of the transmission pan. And please don't under-fill, over-fill, use cheap transmission oil or the wrong type of transmission oil. Make sure you use the kind of transmission oil that your vehicle manufacture recommends. Have plenty of rags on hand. Put some cardboard under your vehicle to catch any spills.

I hope you changed the fuel filter also!

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.

these 3.3l engines are equipped with timing chains. if vehicle has prolonged down time, typically more than 4 hours, vehicle makes a chatter until the timing chain tensioners put tension on the chain. you will need them replaced.
