Saab Story

Technician Ryan inspects the Clutch Assemby of this 1988 Saab 900 Turbo with a leaking Clutch Slave Cylinder and Line. Yep, that's right, the Clutch is in the Front of the Engine Compartment! Saab likes to do things a little differently. For the other 99%+ cars and trucks on the road the engine "faces" forward with the drive belts toward the front (or to the side in the case of Transverse Engines). But Saab has the engine facing backwards -the drive belts are at the Rear of the Engine Compartment (near the Passengers) with the Clutch connecting to the Transmission at the Front of the Engine Compartment (near the Front Bumper.)

Saab Story #2

Here we zoom in and take a look at the Front of the Engine Compartment. The circular shape in the middle of the picture is the Clutch Pressure Plate Assembly.

Saab Story #3

Here's a close-up of the Clutch Assembly with the New Clutch Slave Cylinder installed. Finally!....a Happy Ending to a Saab Story!

Broken Spark Plug is Cause of Mystery Noise...


This spark plug was removed from a late model Toyota Corolla 4 cylinder engine. The customer was concerned about an extremely loud noise coming from the engine. As it turns out the noise was caused by the top half of this broken spark plug moving up and down as the the cylinder cycled between high and low pressure. Also there was a fair amount of noise caused by air rushing past the broken ceramic top of this spark plug.
