Question about 2002 Jaguar S-Type
I replaced the valve cover gasket and the car only has 60,000 miles on it. It ran fine. I crossed the PVC HOSE with a COOLANT HOSE at the THROTTLE BODY. I ran the vehicle approx 30 secs and the coolant was pulled from the RADIATOR to the INTAKE and then into the CYLINDERS, due to my mistake. I corrected the problem, however now there is a VERY LOUD top end noise, which to me sounds like a BROKEN LIFTER or VALVE.
I see now;
do a compression check on the cylinders
this will answer the question if a lifter or, valve is damaged the cylinder pressure will be low

If removing more than one valve lifter (tappet), mark the lifters and their locations as they must be installed in their original bores.

ADJUSTMENT Although it is sometimes possible to reuse an old cylinder head cover gasket, in most cases it makes more sense to purchase a new one before beginning the procedure. Some vehicles may require the use of silicone sealant either with or without a new cover gasket. For more details, please refer to the cylinder head cover procedures in Engine & Engine Overhaul of this repair guide and refer to the gasket manufacturer's instructions.
See Figures 1, 2 and 3
For the intake valves: 1-4-5-8 valve clearance is 0.012 in. (0.30mm). For the exhaust valves: 2-3-6-7 valve clearance is 0.012 in. (0.30mm). The pivot locknut torque specification is 12-16 ft. lbs. (16-22 Nm).
