Rough Running Engine and/or Noise on Mercury Tracer

Valve seats (components in the cylinder head that help seal the valve) can fall out. When this happens, it causes rough running and creates noise. Replacement of the cylinder head is commonly required to fix this problem.

Was driving down the road and started noticing the transmission have a hard time get going and then when it started to idle rough and noticed it was leaking fluid
1997 Mercury Tracer - 2.0L 4 Cylinder 60,000 mi,
No solution yet but ill probably try to buy a rebuilt cylinder head with improved valve seating to prevent further issues with this. Also, make sure all components to the cooling system are 100% because its often the overheating that causes the steel valve guide seat to slip out from the more rapidly heating/expanding aluminum cylinder head.
