crankwalk

i want to get a gs-t or gsx but i have the fear about the crankwalk thing. has anyone had a lot of problems with this? if any.

i'll take this 1

crank walk is the biggest problem that 90% of all dsm owners with eclipse and tsi from 96-99 have it is due to the new 7-bolt motor. the 1g dsm 94 and lower doesnt have this problem because of the 6-bolt motor that those come with.
the only cure for crankwalk if you have a 96+dsm is to replace the bottom end with a 6 bolt motor..

Yes, I've had crankwalk...just had a new block put in....4 or 5 members in my club have had it, one has had it 2x already....
There is a lot of information on people getting this on the web...do a google search or some search engine...just type in crankwalk...and tons of information about it will come up. And don't be fooled...any car can get it....I even have a 1.8 non turbo 1g with it....

uggghhhh....that just sounds like too much to deal with.

hey suit your self...

:wink:

I think it is more like 90% DON'T get c-walk.

nooo its about 90% of all 7 bot dsm owners get c-walk

If you say so:smile:

:bigthumb:

Let me help you with that a bit. The 7-bolt motor actually came in the LATE 92 cars (built after April - May) The big problem was that Mitsu started using substandard crankshafts during the 2G model run. The EARLY 7-bolts may be OK , but the 2G one's certainly aren't. I posted the timeline for engine and turbo types in another thread , you may want to consult that...:biggrin:

Another misinformed CW thread. Hard to believe I know... :iceslolan

Like WRX said, the 7 bolts came out in late 92, for 93 model year. Though some 92 are 7 bolt (very rare). The 1g 7 bolts absolutely do CW, as do 6 bolts. 1G cars do NOT use the crank angle sensor like 2Gs do, so there is no easy way to tell you have the CW. On a 2g the crank sensor will die after the trigger plate hits it (that clicking you hear about) so you are forced to look for the problem. 1g can run for years with CW if it stops progressing. Also, very few cars get it. Not even 10% as suggested above, certainly not 90, lmao. Mitsu would have gone out of business from the cost of warranty motor replacements.

Rather than type all this out again, see the writeup I did here:

Everyone should read this. Its still pretty simplified, but I hope that it helps.

The 6-bolts can crankwalk? I haven't heard anything about that:confused:

any motor can develop crankwalk but the 7 bolt is very prone to it where others are not :biggrin:

again what does this have to do with crankwalk?:loser:

I have 130,000 miles on my 97 gst and i havnt had it yet????

You sound surpised? :smile: Far fewer DSMs get it than the internet warriors will want you to believe. Its mostly the non DSMers talking it up... Go figure.

And 6 bolts do CW. Leon, the guy that ran 11.8 on the 14b, CWed a couple 6 bolt motors. When I went to pick up his race motor, he had SBR do all of the owrk concerning the oil system just so he would have to touch it. Maybe he thought he was cursed, lol :iceslolan So it does happen, and more often than people think. But way less often than a 7 bolt, and 1g cases arent as disabling as the 2g cases (for the crank sensor reason), so you dont hear about them as often...

In my local DSM club there have been about 20 incidents of CW involving 2G's. Granted , most of these guys are running ACT 2100's and 2600's , which are known to aggravate the problem. But its true that CW is rare amongst the unmodded cars. But I'd say between 75% - 90% amongst the heavily modded cars.:frown:

Well the funny thing is its extremely rare in NEDSM (~250 members), and my first 2 motors CWed at 30k and 40k miles, while the one with the 2600 lived to 50k running 12s, and it would have lasted longer had I not dented the oilpan in a rushed headgasket swap... I had the stock clutch start safety swith still there then too (stupid!)... Not to say its not the clutches, I certainly beleive they aggravate the isse, but its not the reason unfortunately... Ah well... :biggrin:

Maybe the Colorado guys are just harder on their cars. We have over 150 members and pretty much all the heavily modded 2G's have experienced CW. 6-bolt swaps are VERY popular here..........:biggrin:
I've heard several theories regarding CW , most involving inadequate oil flow to the center thrust bearing or the piston squirters operating at idle when they shouldn't be , taking oil away from the thrust bearing...... Care to shed some light? :confused:

I've heard more theories than I'd like to remember... Most of what I know about CW is in that thread I keep posting a link too. I really should go back and update that though. But its all the same reasons weve heard before. The most import thing to take away from all of these crankwalk discussions is something I have learned with my car. All 2g motors are born with a potential to crankwalk. If you give it the slightest reason to do so, it will walk. Always makes sure there are no screw up with the oil system. My second motor CWed because the infamous oil mixer/cooler came loose. The next motor was lost to a dent in the oil pan under the pickup, etc. So its not entirely the motors fault when people CW them, at least some percentage of the time. This could be part of the reason the stock ones in your area do better. People aret messing around with critical oil system BS, things that you may not even know you disturbed. But there is defintitely a flaw in the design/execution of the 2g motors (and others) also. What that is could be a combination of any or all of the reasons being circulated around...

hey all I just joined this forum

I've got a '96 eclipse gs-t for about a month now

I love the car and all 1g and 2g eclipse but not the new ones though...

anyways
the check engine light started coming on a while ago
my clutch isn't sticky during left turns but my engine sounds a bit rough
though the oil is kinda dirty so I gotta get that changed soon (and I figured that could be it, at first)

the car's got 107k miles on it right now and I'm worried if I'm gonna get cw or not

any ideas what I should look for?

thanks!

With that kind of mileage its VERY unlikely you'll get it, unless you give it a reason (cooler backs and dented oil pan examples I gave above). If you get it and it gets bad, it will take out the 2g crank angle sensor and the car wont run. If you want to track it and monitor the thrust play anyway, see that thread on RKO I linked to on the first page of this thread. Use the dial indicator method of mearuing the play that I outline there. Dont be alarmed if the number is high, many high mileage cars are. Just watch over time for it getting worse ;) But in reality there is nothing you can do to stop it once it starts, so how useful knowing that endplay is getting worse is a matter of debate.
