My timign belt broke the other day and when I replaced it and checked the compression it read 0 on all cylinders so i guess bent valves! what are the chances of having piston damage? Also if someone has a good web site with step by step of how to remove the cylinder head that would be great! thanks!

I did my Elantra timing belt last month. I found the hmaservice.com site almost useless, and basically winged it.

Just curious... are you sure you got the pulleys lined up correctly when you replaced the timing belt?

Thanks! I checked that web site and didnt see anything for that.

Typical Hyundai --> Disconnect battery,,,, remove cylinder head......... re-assemble in reverse order.. :thumbsup:

Not very hard to get head off, leave the cams in I think, your choice, remove intake or leave it on, but exhaust manifold is best removed.

Might be able to slide intake away enough to allow remove of head itself, be lighter and smaller..

Note the cams is tied together with chain.... mark that joker !!! mark a link and tooth on exhaust cam, do same for intake cam... that way you assemble links to marks on gears, no problems.... Elantra manuals is wrong,,, BEEN THERE

What procedure did you follow when doing the pressure test? I guess I'm the only one who thinks 0 psi on every cylinder is odd, even after a broken T-belt?.?.

with the new belt on I took all the spark plugs out screwed the compression gauge in, turned the engine over with gas pedal in. I did this on all 4 and they all read 0.

you will need to pull the cylinder head off, you have bent valves ( l presume you have fitted the timing belt correctly)

is there a way i can check for piston damage with the head off ?

Look at them for dings where valves collided.... Usually not a big deal, only to valves that have bent tulip to stem. Be aware on valve giudes in the ports, make sure they not have ends broke off.


Got pictures yet ??

130,000!!!! I thought that it was chaged by its last owener but after talking to her it was never chagned so it was long over due lol.
Sorry you had that happen but it makes me feel less edgy about having 29k and a little over 5 years on mine. Hope things go well and as inexpensive as possible for you.

With the head off you will be able to see all 4 pistons, and any damage done. I still find it odd that all cylinders have 0 compression. Have you checked your gauge?

looks like I need to take the rear motor mount off thats connected to the intake manifold.. is there a easy way to do this?? lol probably not. I got it unbolted from the manifold but you cant just simply push it out of the way so it looks like I need to get the bolts out from the block as well :(
