I was in this websites classifieds and there was a 98 talon I believe and the guy who was selling it wrote this "97-99 engines are free of crank walk issues due to the revision of the oiling system" is this ture or is it a bunch of wishfull thinking? the reason I ask is because I'm wanna sell my gs and get a gsx but don't know if its worth it because of cw, i like the 1g 6bolt cars but I'd prefere a 2g and I don't have any idea which one to go for, its driveing me crazy, but yeah I thought all 7bolts are bad with cw

I think many will agree that crankwalk is overrated. It doesn't happen THAT often, but rarely it does... and it doesn't only happen on DSM motors either... and as for the guy in the classifieds, unless he did it himself, I don't think Mitsu did anything diffrent on the 2g motors throughout the years, don't quote me though.
I love my 2g motor, although I was already about to buy a new motor when i bought this car, I realized if it hasn't happened, then it probably won't.

Dont let crankwalk scare you. Only a small percentage of them actually walk. From what I hear, people claim that 97-99 are less prone to walking, but never said why.

If it walks, put a 6 bolt in it. Problem solved.

1G seven-bolts are just about as strong as 1G six-bolts. It's just the 2Gs that had the crankwalk problem really get infamous. No one knows why the 2Gs really walk so much more often, though there are a lot of theories (my favorite being the batch of badly machined cranks being matched with special main bearings, and having some get mixed up).

Try to find a 2G with a six-bolt swap, if you're addicted to the 2G looks. Probably won't be cheap though.

Hmmm, what's a 1g 7 bolt? Is it the 95-96 period?

I'd have to say he's full of it for 2 reasons:

1) My motor crankwalked. Yes, true confirmed CW which destroyed the motor. My car is a '99 conflicting with the claim that this model year wont walk. I have since done a lot of reading on the subject and never came across any literature supporting his claim.

2) As Talesin mentioned, it hasn't been clearly established what caused unusually high incidents of CW in the 2G's. So to say that a revision of the oiling system took care of the problem when no one clearly understands what caused it in the first place is misleading at best and a down right lie at worst.

However, I have frequently read that CW was most common on cars manufactured between late 1995 and mid 1997. Maybe he took this info and twisted it around to come up with the embellishment.

I believe that it's second half of 92 through 94. Correct me if I'm wrong.

yeah 1g's from april 92-94 were 7 bolts, 90,91,early 92 were 6 bolts

You are right.

95-96? Wow, back to basics on years and gens here are we?

One more question from you very helpfull guys How difficult is a 6 bolt swap into 2g? with the 1st generation 92 and up, is it a perfect fit? do 1st gen 7 bolts get c/w? are they reliable? and is it possible to make a 92-up front end converion to the 90,91's? well I guess that was more than one question but I figured I'd save space and time and not start another topic. Thanks to everyones input, you guys are awsome, I love DSM's ! there I said it

Doesnt CW only happend if you make a very sharp turn? In wich it causes it to slip out of place and causes the motor to come to a complete stop.

No, CW is basically a toss-up from the factory. It isn't "caused" by anything you do. Clunking on a sharp turn however is one of the many ways it rears its ugly head, but a turn won't create it. Close, but no cigar.

CW is most noticeable after a sharp left turn, then pushing in the clutch and trying to change gears. The travel of the clutch is used up pushing the crank back into position, instead of releasing the pressure plate so you can shift. That's just a symptom.

90-91 = 1Ga. six-bolt engine, three bolt rear on the AWD variants. Popup headlights.
92-94 = 1Gb. six-bolt engine on early 92, seven-bolt on 92.5-94. Four-bolt rear on AWD. Fixed beam headlights.
95-96 = 2Ga. Seven-bolt engine. Early models had slotted rear disc brakes. CAS is located stupidly, behind the intake cam gear. 95 is the last year you could possibly get an EPROM ECU.
97-99 = 2Gb. Seven-bolt engine. Minor body redesign, CAS returned to a hall-effect sensor on the passenger side end of the intake cam.

2Gs are known for crankwalk, as it became a fairly widespread problem compared to most other vehicles. Swapping a 1G six-bolt is NOT a simple affair, though many have done it. There are harness adapters to make things easier (read: so you don't have to cut your wiring and splice it all over the place), but it's still not a trivial task. Seven-bolts I can't speak for, as I've never really heard of anyone tossing a 1G seven into a 2G... everyone just goes for the six, since they're colloquially 'known' to be stronger engines.

Well after some thought and some input for you guys I'm leaning twoards the 1ga awd it seems like the best choise, affordable, reliable, and alot of mods=fast ass car.

Thanks Talesin for good information
"95 is the last year you could possibly get an EPROM ECU" so what do you use for 1g's?

Seeings as how I've never seen a "reason" for crankwalk that I completely agree with, I also don't believe there is or was any one cure. Yes, that line was bullshit. I've not heard of a "revision of the oiling system".

There were some differences between the 98-99 motors and the 95-97 motors.

Also, according to the surveys that were done on CW and all 7 bolt motors, it seems that somewhere around 80% (can't remember the exact figure, but this is close) of all CW victims were owners of 95-97 years. A very small percentage were 1g 7 bolts, and an almost as small number were 98/99 motors. There were a couple registered cases of 6 bolts walking, but that was 1% or so.

I couldn't tell you why, but the numbers say they did something differently/made some changes.

I have heard of the crankwalk revision, a company around my area in Argyle NY does a revision that supposedly prevents crankwalk from ever happening.

http://www.overbore.com/crankwalk3.html

I am still doubtful but i guess anything is possible.

I don't remember where, but there's also a guy building 2.3's out of 7bolts specifically and gaurenteing then from EVER walking.

A 1Ga GSX is the way to go in my book, but that's because I like how the popups look. The headlights are painfully weak, and there isn't really much you can do about it, aside from find someone still selling the Hella H4 conversion kit for 4x6" sealed beam. Also, they're geared a lot lower than the FWDs (need the extra torque for the AWD drivetrain), so get crap for gas mileage by comparison.
And if you can, get a '91. Love my '90, but they're the bi*** car for a reason. Funky ass electronics, weird problems that pop up and go away without rhyme or reason.

Otherwise, a 1Gb GSX would be even better, if you can give up the popups. Get an early-year model, and you get a few notable upgrades.. 2-pot front calipers, and the four-bolt rear end. Early half of the year had the six-bolt engine still, but the seven-bolts are just about as good. Should be able to pick one up pretty cheap, and dump the extra few thousands you saved (compared to buying a 2G GSX) into repairs/maintenence, then a very nice chunk of upgrades. Personal opinion though.

I like your fist opinion after some looking arround the popups is what I'm gonna go with. the reason why I asked about the conversion is because my first car was an f body and it had popup light and there was alot of complications. But aside from that could a 4 bolt rear go on a 1ga? would it be any better than the 3bolt? or it dosent really make that much difference?

Yes you can swap the 4bolt, 2pot calipers, there's a lot you can swap over. Personally i'd try to find an early 92 like mine. 6bolt 4bolt stock! But if you're partial to pop-ups, then by all means find a good 91!

So for those of you who have CW how many miles did you have before this happened. From what i have read in many places if it doesn't happen with in the first 75k you should be ok. My first 7-bolt had 165 on it before it spun a bearing but no CW my six bolt broke a ring in cyclinder 4 and now my 2nd 7 bolt runs better than both the 1st and second motor. but i have a 1g head and cams in there so that makes a big difference

Well these used to be a poll, and I think yah it was within the first 80k miles or something.
I was changing the timing on my car this weekend, and I was in there pulling on the crank like no other... didn't budge a millimeter, even w/ the prybar... isn't it supposed to move a little?

39,000.

Early 1G all the way!!!!!! Try to get a 91. The pop up headlights add about 50horses alone!!!

They are actually vented rotors not slotted rotors. It was a minor typo but funny when I read it.

I agree with eboy. Crank walk is very overrated and more than half the time people will blame crank walk for any strange noise that might come from there engine. I do believe that some people are starting to wise up and understand that not all problems with the engine are automatically crank walk. Back to topic. I was under the beliefe that the 4g63 motors in the 97-99 were no different than the 4g63 in the 95-96 models. I 109xxx miles on my GST with the stock motor and internals on it and I have no symptoms of crank walk. I also don't agree with the statement that crank walk happens less on the 97-99 models because I have to local DSM drivers one has 98 and the other 97, but the 98 walked and that is a fact also and I was helping remove the block when crank walk was concluded and the 97 driver claims that he walked his over the weekend I will be able to find out if it did or not by thursday when I get back in town. Both of these cars have under 100xxx miles on them so if this one turns out to be CW as well then that makes two of the 2gb eclipses that have gone down the chute because of CW. As defiant said I haven't found any real reason that assures me exactly why crank walk happens in the 4g63 engines, and that there is no real sullution to crank walk. There are many ways to help prevent CW from happening, but there is yet to be a proven situation where Crankwalk was completely ommitted from the engines. If anyone of the people that stated the different shops that say they can completely gaurentee CrankWalk from occuring then I would like to see real numbers from the vendor and I would really like to understand their findings and what they did to get rid of CW for good.
