I don't believe that crankwalk is a problem with your year of car. It affects the 95-99 4G63's. Also, I remember a post not to long ago were this problem was discussed, and it only happens to around 10% of the motors. Don't lose any sleep over it. If it happens it happens, which would still suck nonetheless.

Goblin, your car 1g nt, is the most likely to never see crankwalk ever! I have never once heard of a non turbo motor walking in a 1g or even a 2g!!!

crankwalk happens to 2g turbo models. happens more often around 350hp+ i have heard.

Yeah, well thanks for all of that info. Perhaps next time when I post I'll be a little more clear.

I'M AWARE that 1gs don't get crank walk. I'm BUYING a new 2g TSI or GSX. I know it only happens to 15% of all 2g DSMs but if it's cheap enough I'd rather just replace the crank bearing so I never have to worry about it grinding through the sensors and wreaking all sorts of havoc later, or atleast have the $ set aside in case it DOES happen.

So, I appreciate the comments, but you guys are telling me sh-tuff I already know So again, if anyone knows how much it's going to cost to have a mechanic match up my crank to the right aftermarket bearing and replace the defective bearning, how much is it going to cost me?

Or better yet, how hard will it be for me to do? (yes I have plenty of means to do such a job my father was a diesel mechanic and when he died he left me ALL of his tools and machines).

big relief to know that crankwalk ist a prob. among 2gs

crank walk is very expensive to fix, and once its fixed, its possible to come back. If your car walks, get a 6-bolt motor.

Not sure if this info really helps but I actually had crankwalk.

My car suffered crankwalk in early 1996 (its a 1995 TSI AWD). I had 12,350 miles on it and zero mod's....again zero modifications. I treated the car very well, no racing yada, yada.

At the time me and two other guys were going through the crankwalk ordeal before they had tagged a name to it.

Here were my symptoms: Clutch pedal would not pop back up at times, loud ticking sound from engine bay, louder ticking sound when clutch pedal was pushed.

Lucky for me my car was under warrenty, the dealer replaced the crankshaft, main and rod bearings, clutch, numerous seals, and reserviced the AC. Total Cost 3,200 with labor, remember thats at dealer rates. It was in the shop for 3 weeks (lots of parts delays).

I havent had any problems since, my car has 70,000 on it now, with lots of racing and mod's including a performance clutch. If I were you I wouldn't worry about it just make sure the car your going to buy doesn't click with the clutch in. If the car hasn't developed symptoms by 50,000 or so, it probally won't.

BTW I got to read the intial service bullitens on crankwalk (excessive thrust play in crank shaft) and Mitsu. blamed it on installing cranks ground out of tolerance and shotty bearing installation on the factorys part.

1) This is not only a 2G issue.
2) I have walked both a 7-bolt motor and a 6-bolt motor in my 96.
3) Crankwalk is a 'pre-worn thrust bearing'. Any car with a 'thrust bearing' can 'pre-wear' that thrust bearing. Even a 1G NT will 'walk the crank' if the thrust bearing is misaligned during a rebuild.

The real question is why do stock block engines (regardless of mods) in 2G's have this happen much more than any other 4G63. Answer that and you have the answered the question no one else can.

I thought the main cause of crankwalk is the moving of the defective bearing on the crank that mistsu used. It goes from side to side and wears down then shaves off the crank sensor, then keeps wearing from side to side until the bearing wears to nothing and well you get huge problems.

So shouldn't it be as easy as replaceing the crap bearning that mitsu KNOWS is defective because it wasn't built to spec? I read off of dsm.org out of the digest that it was simple as that and a ton of poeple have done just that to fix it, and some went as far as to get a new crank too.

There are no bearings on the crank. The bearings are attached to the block. The thrust bearing locates the crank laterally. When the crank grinds away at the the thrust bearing, lateral play (or end play) occurs. This eventually kills the crank sensor as the trigger plate eats it away.

How do you know if CW killed your motor or not? My motor died a while back and was curious if CW had something to do with it. I still have the old block, so is there something I should look for to let me know if CW did break it.

When you pull the oil pan, check your thrust bearing and measure the lateral play at the thrust bearing. If the bearing looks like copper and there is more than .008 of play, you have a worn thrust bearing.

Right On! Totally agree.

I dont think anyone really knows why they crankwalk. I have heard so many different things now I lost track. Bad bearings, amount of iron in the block,etc. Sean Glazer of Extreme Motorsports says its the amount of pressure in the master clutch cylinder or something like that. I just dont get why so many 2nd gen 7 bolts walk but so many 1st gen 7 bolts are crankwalk free. Seroiusly I wouldnt even worry about it unless it actually happens. Just get the car and enjoy it.

Alot more 1g's have CW than you all think. They just don't have a crank sensor getting in the way. It's a common attribute to shitty 1g shifting problems.

Check it and you might see .

Amen! I have been preaching that for a while now.
