Where did I go wrong?

Asked by Jun 29, 2014 at 12:51 PM about the Kia Rio

Question type: Maintenance & Repair

I have a 2004 Kia Rio with the 1.6 MI Tech dohc. The timing belt had jumped 180 out. So I
replaced and adjusted it using the markers on the gears and motor. Put it all back
together except for the top timing belt cover. Now it acts as though it lost compression.  
Where did I go wrong?

Hate to say this but that's an interference engine. You probably got some bent valves in it now. Do a compression check on all cylinders. Any showing 0 psi will have bent valves.

When an interference engine jumps time, timing belt breaks or improper timing belt installation occurs there is a possibility of bending valves.

Wouldn't the bent valves make some noise though?

Not necessarily. I bent some once and there was no difference in the sound of the engine turning over. Only way I figured it out was with a compression check. I had six bent valves in just one head.

Ok I had no way of getting a compression gauge so I took the head off and checked the valves. None of them were bent or warped. Head gasket had a slight leak from it so needed replacing anyway. Still not cranking.

Sounds like you replaced the timing belt with the crankshaft in the wrong position. That's why you need to check cylinder 1 to be at TDC when aligning the timing belt. The only other way to be 180 off is with a car with a distributor and installing the plug wires 180 off. I had a friend rebuild an old Fiat and did both. The combination of timing belt and plug wires being 180 off worked!

Doing a compression test, how much compression should each one have?
