In 93,000 miles and 10.5 years, we've replaced:
- Alternator at less than 70,000 miles
- Serpentine Belt Tensioner at 90,000 miles
And just today, I pull off one spark plug wire and got the whole top-end of the engine flooded with oil.
It appears that the valve cover gasket and tube seals are toast, causing oil to leak into one of those holes. No wonder we've had driveability issues! The spark plug wire boot in that cylinder (#1) seems to be greatly affected by the oil and hasn't sealed well for the last 30k...
So adding to the list, I must still replace:
- Engine Coolant Temperature Sensor with the updated "metal" tip due to stupid GM engineering's decision to originally use a plastic tip.
- Transmission Valve Body, due to wear issues, thankfully aftermarket has the Sonnax sleeve for the pressure regulator valve bore wear.
- Transmission Valve Body Cover gasket
- EGR Valve cleaning
- PCV Valve
- Motor Mounts...which seem to need replacement every 50k, at least.
- Valve cover gasket and spark plug tube seals
- Spark Plugs (again)
- Spark Plug Wires
Is it normal for one, to need to replace so many items before 100k miles?
