HELLO! My question is my 1999 ford escort makes a rattling noise in the engine. When I accelerate the rattle gets worse when I take my foot off of the gas the car dies. Fluids look good and it starts fine. Can anyone help with this problem. Someone said it could be a push rod. Thank you!

Could be any one of these making your rattling noise you really need to get your shop to check this out?

Hydraulic Valve Tappet
Check contact and sliding surfaces of valve tappet for pitting, scoring or excessive wear. Replace valve tappet if plunger is not free in body. Plunger should fall with own weight when assembled dry.

Valve Springs
Measure free length of valve springs. Check springs for cracks and out-of-square. If any measurement is not within specification, replace valve springs as necessary. See VALVES & VALVE SPRINGS table under ENGINE SPECIFICATIONS.
Valve Guide
Measure valve guide height from spring seat to top edge of guide. If valve guide height is not within specification, replace valve guide. See CYLINDER HEAD table under ENGINE SPECIFICATIONS. Measure valve stem-to-guide clearance. If clearance is not within specification, replace valve and/or valve guide. See CYLINDER HEAD table.
NOTE:Always reface valve seat after replacing valve guide.

Valve Seat
Inspect valve seat for evidence of roughness or pitting at valve contact surface. Reface seat as necessary. Before refacing valve seats, check valve stem-to-guide clearance. If clearance is not within specification, replace components as necessary. See CYLINDER HEAD table under ENGINE SPECIFICATIONS.
Ensure valve seat width is within specification. See CYLINDER HEAD table. If servicing valve seats, valves must be serviced or replaced. Valve seat replacement information is not available from manufacturer.
Valves
Measure valve stem diameter at top, middle and bottom of valve stem. If valve stem is not within specification, replace valve. Measure valve head margin. Replace valve if not within specification. See VALVES & VALVE SPRINGS table under ENGINE SPECIFICATIONS.
