HOW TO MEASURE VALVE CLEARANCE

2000 Hyundai Elantra

Engine Mechanical problem
2000 Hyundai Elantra 4 cyl Front Wheel Drive Manual 140000 miles

Have a 2000 hyundai elantra 2.0 dohc. I am confused on how to check valve clearance.I have only been able to barely fit my smallest feeler gauge(.0015) between the cam and the shim that the lobe hits. Am I checking these clearances right? The timing belt broke on this car, I took the head off and all the valves seem to seat fully while turning the cam. Does an interference engine not always bend valves?

Hi there,

Thank you for the donation,

I am a bit confused here, I only get a single cam engine for your indicated model, what is your engine code? I get a G4GF engine for your model a single over head cam engine with hydraulic lash adjusters.

This is a 2000 Hyundai Elantra, 2.0L DOHC. Says DOHC on plastic engine cover, and does have two camshafts over the valves. The 8th digit on the VIN # is F. Not sure about the engine code you listed? I am pretty sure this is the original engine. I have an online hyundai repair manual that confirms this an an engine offered for this 2000 hyundai elantra.. Anyways after further inspection of the valve clearances, I found a few intake and exhaust valves that had a real low clearance(less than.005), and others look normal with measurements around.020. Will drop the head off at a machine shop and have it inspected, and see what they advise. After the timing belt breaking and seeing valve clearances out of spec, I was sure I would find bent valves not seating fully. Do you think I was just lucky that no valves were bent or pistons damaged on an interference engine? I will post results after having the head inspected by a machine shop. I am tempted to put the head back on, but want to have it looked at first. I will post results, maybee this will help someone down the road.

Hi there,

OK, maybe its a miss print in my data base, anyway I would be extremely surprised that you don't have at least one or two damaged valves, with the head off they can do a pressure test of the combustion chambers, this will show up any leaking valves due to bend or seat & valve face problems, the tight valve clearances may just be due to normal wear and tear, but with the head off, all will be revealed.
