CrankWalk Poll [merged]

[ChrisHKS]

im starting this forum like a poll. i want to know (and sure others too) how many of you tuners have actually gotten crank walk on there 2g and wanna hear all the people that havent. please just leave a reply if u have gotten it or not. thanx-greatly appreciated

just wanna see how common everyone makes it seem

 

[Sinister]

Well....... I thought that my car has not crankwalked......thought it was 60k and still strong. Until I found out that the engine was replaced under warranty at 32k. So technically im 28.5k and strong. Can be good , but can also mean very bad things

why does it matter what clutch you have, how does that effect c-walk

The stronger the clutch that you have, the more pressure will be applied to the thrust bearing, which in return will lead to the dreaded CW, if I'm not mistaken.

 

[Patryk]

what symptoms are there besides clutch not coming back up on left turns?

 

[Snake]

My 96 gs-t youst crankwaled on me last week it had 61,000 miles on it.
I am going for a full rebuild but I got me a 97 small block.Now I can tell you that this block has a diferent desing for the bearring caps.
So I guess that crank walking a 97 or older model it would be less posible.

 

[spac3y]

How do the caps differ? Is it a change that would work on our 7bolt crankwalked blocks?

 

[shadowgear]

I have a 95 gst and its all stock. I have about 160k and its still running strong, but i have noticed that my clutch is starting to lose pressure and my idling is kind of screwy. Other than that Its fine. I plan on a rebuild as soon as I get some money. Its interesting to note how the 95's are still kicking.

Based on responses so far it looks like:
1995 - 41% crankwalk
1996 - 33% crankwalk
1997 - 32% crankwalk
1998 - 4% crankwalk
1999 - 5% crankwalk

The 1998 and 1999 numbers aren't that accurate though since it's a smaller sample and only one victim on each.
Someone probably already brought this up, but what would be really cool would be to tabulate milage, what clutch each victim and non-victim has, and perhaps driving style (lots of sitting at lights with the clutch in, or lots of high speed cornering, or drag racing, mostly highway miles, etc), and maybe even type of oil and frequency of oil changes. That would be a big survey, but might provide real, usable data that could help those of use who haven't walked yet to prevent it (or hold it off as long as possible).

No crankwalk

'99 GSX
56,000 MILES
ClutchMasters 2500
Daily driver 50% stop & go
Part time 1/4 miler
Mobil 1 10w30 winter
Mobil 1 15w50 summer
Mobil 1 oil filter
Change oil & filter every 5000 miles
I do not idle in gear with my foot on the clutch
Clutch safety switch bypassed to start vehicle

Checked crank thrust end play recently, measured .0050
Normal is .0020 - .0071, limit is .0098
Oil pan off this week to remove balance shafts, no signs of any bearing, crank, etc. material in windage tray or oil pan.

Hope this helps

 

[zerofreez]

151k on a january/95 tsi awd

No crankwalk

act2100 since 110k

 

[eclipsinemcee]

my 97 walked at 77k with a stock clutch...now i gotta sixer in

 

[blackawdturbo]

My '95 seized a rod bearing at 120,000 miles but thrust play was .006" so technically the motor was fine. Anyways I've switched to a 6 bolt motor but in the poll I voted no CW since I am positive it would have run many more miles.

 

[spac3y]

Wow! Now if only all of them would last that long things wouldn't be so bad!

yea the 98 and 99's are going to be lower because they are the newer models. it seems to me alot of the 97 gst's walk alot.

The late '98 & all '99 models have the new thrust bearing design which is supposed to fix the problem.

 

[tqlla]

98-99 cars are 4 and 5 years old now. Thats enough time for people to put 100K miles on the cars.... although I have a 99 with 55K miles and I do fear Crank walk... and my car does make a lot of noises... =(

[malern28us]

has anyone transplanted a 4G64? It has to be easier than the 6 bolt swap.

It seems to me... that according to THIS poll the 95's are walking more.

 

[Smokin GST]

97 GS-T
CW @ 100400 miles

my crank angle sensor is dangling on the right side of this picture. you can see the little part of the crank disc that was rubbing on the crank angle sensor... it's the shiney little piece next to the bolt hole left and down from the center of the picture.

You must be logged in to view this image or video.

sorry for the blurry picture. i was real close and the camera wouldn't focus. 6-bolt is going in as soon as i get a 6-bolt FWD flywheel.

 

[kpt4321]

My 93 7-bolt walked.

Here's a good question: Of all of you that say your car has not walked, have you measured the endplay? I would be willing to bet some people on here might be surprised.

Is it more likely to get CW if dumping the clutch under heavy power or easing it out till it catches and then putting on power?

Won't make a difference, unless you keep the clutch pressed in while sitting in traffic. It's the pressure of the throw-out bearing pressing against the clutch diagphram that pushes the crank in against the thrust bearing.

One thing to keep in mind on this is that the age goes accordingly to the percentage of CW for the most part that is and logicaly that makes since.

I was told by a mechanic at the dealership near me that a major cause of CW that he had seen was dumping the clutch under extreme power (mostly modified cars), so thats why I was under the impression that if your not too rough on it then its not as bad a problem.
