Valve Knocking Hardcore

[b00stingsx]

the other day on my way home, I began to hear a belt squeel. i didnt think much of it since i knew that my ac belt wasnt connected properly. 2 minutes later, the car immediatly starts pinging. I pulled over and shut the car off immediatly.

So i tow the car home, and start taking her apart. timing belt looks fine (not shredded or falling apart), so i look on the ground and notice there is some drops of coolant on the floor. I take the water pump belt and pully off, the ac, the alt., the ps pump, all the accesories off. i start the car and it still pings.

I took the valve cover off, and everything seems to be ok in there (nothing is out of place, cracked, etc....).

i manualy turn the crank until the exhaust and intake cam marks are at 3 and 9 o clock. They line up perfect (put a ruler across and they are right in line).

what do I check now? It totaly sounds like my valves are hitting the tops of the pssitons.

HELP

What you hear is probably lifter tick. Was the car losing power when the noise started?

Your cams line up with each other, but is the crank at TDC when the cams line up? Also did you pull the plugs to make sure one didn't crack and fall into a chamber?

matt, I think it did in fact lose some power, but its hard to tell. I will check for the TDC and plugs sometime today. when i turn the two cams to 3 and 9 o clock, do i check the height of the pistons with somthing similar to a coat hanger in the cylinder to see if the crank is too at tdc?

The easy way is to check the mark on the crank pulley compared to the timing marks. That isn't 100% accurate, but is close enough to let you know if it is off. The real marks are on the crank, but harder to get at.

If you still have it apart, pull the timing cover off and check teh timing after lining up the crank sprocket. There is a mark on the pully which a metal piece points to. You can borrow my manual if you want. I believe it shows a pic.

where should these marks be in perspective to the cam gear marks?

When the cam gear marks are lined up, the mark on the crank pulley should line up with the timing belt cover at 0 degrees TDC.

Are the balance shafts still in the engine?

ballance shafts are still in the engine.
