Oh you know about that, eh?

Well, I actually have the reverse air intake that draws in air through the exhaust pipes, so it's like, crazy fast.

 

 

What does that even mean? crank walk?

 

The 4G63 is prone to crank walk it is more common in the American 2nd gen 7 bolt but the 6 bolt 1st gen also had problems with it. Its a DSM joke just like the mazda have ZOOM ZOOM BOOM jokes we have crank walk jokes.

 

Note that when i said American i was referring to the American 4G63 the 1st and 2nd gen eclipse where never sold in japan however mitsu has been using different versions of the 4G63 in there vehicles since the 80s until recently when it was replaced with a new power plant in the EVO X.

 

that doesnt tell me what crank walk is.

 

he means what IS crank walk.

im not 100%, but i believe what happens is the crank bearings wear on those motors which allows the crank to shift slightly, basically turding the entire motor

 

Play in the bearings can cause the crank to travel (walk) back and forth along its axes of rotation in the block, eventually wearing out the bearing housings and potentially damaging the block itself.

"Crank walk" is often mis-diagnosed by dealer technicians. We've heard of car owners replacing multiple clutches trying to fix a clutch problem, when the problem was really crank bearing wear.

There are several theories about why this happens, including bad crank machining, oiling problems at the bearings, and excessive bearing cap tolerance. So far, no theory is proven, since the problem takes years to show up, and none of the possible solutions have been in place for that long.

 

Spec beat me too it.

 

..... could delayed and hard shifting intodriveand askipping transmission in high rpmsbe one of the mis-diagnosis?
