2004 Hyundai Accent - baffle inside valve cover oil filling opening. What is it purpose and is it needed? It was broken off and just laying inside of the cover.


It reduces Valve train noise and stops oil splatter from exiting engine if cap is left off. I think it just lays on top of valves. Then you install valve cover. I would leave it on

Top end engine noise-valve train?


You may be coming up on the maintenance interval for a new Belt, but I would imagine that this vehicle has VVT, variable valve timing, and that you may need an adjustment on that as well.
Valve noise is most likely what you are hearing.

Noise sounds like a metallic chirp from valve train.


To narrow it down, while the engine is running, don't get near moving parts, you can use a long piece of steel, metal, put 1 end on the valve cover, the other to your ear and listen for rattling. You can move it around to narrow down the source of the noise. It's like a stethoscope but works well. I use a 3' long screwdriver.

Hi , I've got a tapped noise on my Sonata 2.0 L GL4. Can anyone help please ?


You may have low oil pressure due to a plugged passage, have you tried flushing the engine with any of the commercial engine flushes out there, shops also do this service. It is also poss that the noise is not the valve train but piston skirt slap.

If you break a timing belt on a 1998 hyundai excel 1.5 Dohc will it spin free or will the pistons contact the valves?


Both. When it normally runs valves come very close to pistons. If belt breaks, any open valves will have come in contact with pistons and usually bend or break, but engine will free spin.

My 1998 Buick Lesabre ,I just had an oil change, it just developed has noisy lifters. Also the antifreeze reservoir is always losing the fluid, I am always refilling.


Suggest you check your exhaust on startup, is it very steamed up. Unless you see fluid on the ground after you have been driving, it may be being burnt inside the engine via a leaking head gasket, causing part of the head to misfire, 1 or 2 cyls. Is the oil milky? a sure sign of a leaking manifold gasket. At the end of the day, the coolant must be going somewhere, if its not on the floor, its in the head/manifold. A manifold leak is not so bad, Head gasket is not so good..worth doing a compression test and block test if you can.Also, change the oil again and put in at lest 10W-30 weight, your car is too old for 5/20 5/30...Hope that helps..Tim

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.

Valve train noise


If the tapping noise speeds up with engine speed, a bad valve lifter.Depending on if it has hydraulic valve lifters.

I have a 1998 hyundai excel 1.5litre


If the noise is emanating from under the valve cover, it isn't the timing chain. It can be a stuck lifter and you might want to try a lifter cleaner from an auto parts store. I think you will need to change the oil after adding the cleaner and running the engine for a while. If the engine uses mechanical lifters, the noise could be coming from a bent rocker arm or a worn push rod.
You may be able to narrow down the source of the noise by using a longer screwdriver, placing the tip at various places and resting the handle on the bone behind your ear. Obviously, stay well clear of anything rotating.
