Note to all the poor souls who own the 2.0 SPI variant.

2001 Ford Focus SE 4dr Sedan (2.0L 4cyl 5M)
As the title states if you own the 2.0 SPI SOHC aka (2.0 split port) variant.
Sell this car immediately it's a literal time bomb. Possibly the worst engine design by Ford ever.
No matter how you baby that engine expect the valve seats to fly directly into the cylinder head anytime after 70K miles. The minimum cost to fix is actually almost as much as the cars valuation.
Even if you catch it prior to damage it's a very costly fix and one that could have been avoided by Ford if the had made a slight design variation to the 2.0 SPI.
Symptoms of failing valve seats include.
Running rough or stalling in idle
A #2 or #4 cylinder misfire code
Avoid the Focus VIN P at all
Maneuverable extremely fun to drive in traffic. The maneuverability of a fighter jet saved my bacon multiple times in an area where drunk and stupid is the rule not the exception when it comes to driving.
Acceleration (meh) it takes awhile to get from 45-60 I hear the Zetec is a more reliable engine with a little more oomph than the 2.0 Split Port.
Fuel cost it's not the lightest drinker at the bar but acceptable. Fuel cost to fill it up, roughly $25
Slight Modification to the 2.0 SPI engine design would had made the difference between a 70K engine and a 300k engine. :(
