What can cause crank walk?
The movement is usually due to the crankshaft not fitting inside its bearings correctly. While not bad for the crankshaft, the movement can place excessive or uneven loads on the bearings, causing premature failures. Many 2G owners have suffered from walking crankshafts.
How do I check my crank walk?
1. Put a prybar on the crank pulley and try and move it back and forth to see if you have excessive play. 2. If it is a 5 spd drive it down a curvy road and when you take a hard left the clutch pedal should drop, if not stick to the floor.
What is a 7-bolt?
The 4G63 engine comes in two varieties, and they’re distinguished by the number of bolts that hold the flywheel to the crank. If your car is a 90 or 91 and has its original motor, you have a six-bolt motor. If you car is a ’95 or newer turbo car, you have a seven-bolt motor.
What does it mean when your crankshaft is walking?
A ‘walking’ crankshaft is a crankshaft that moves too much inside the engine. This is also known as excessive thrust bearing play. The movement is usually due to the crankshaft not fitting inside its bearings correctly. While not bad for the crankshaft, the movement can place excessive or uneven loads on the bearings, causing premature failures.
What kind of engine is prone to crank walk?
It has been reported that ‘small rod’ / 7-bolt flywheel motors (manufactured from later 1992 through 1994 on 1Gs) are more prone to crankwalk than ‘big rod’ / 6-bolt flywheel engines (manufactured from 1989 to early 1992). However, there can be no guarantees, since big block V8s and all other engines can also suffer from crankwalk.
Can a small rod flywheel engine crank walk?
However, it is possible for any engine to experience crankwalk if there is a problem with the crankshaft bearings. It has been reported that ‘small rod’ / 7-bolt flywheel motors (manufactured from later 1992 through 1994 on 1Gs) are more prone to crankwalk than ‘big rod’ / 6-bolt flywheel engines (manufactured from 1989 to early 1992).

Is there a way to fix engine knock?
A computer can recognize this issue, but can’t automatically correct for it, as parts will need to be adjusted or replaced deep within your engine. Engine knock isn’t always the easiest car problem to repair. Here are a few of the most common solutions to knocking issues.
