about crankwalk in a 7 bolt..........?

[eclipse2hotforu]

ok heres the question...... i know 7 bolts r known for crankwalk when u add so much hp to them.... well...... i know they say that about the 2nd gens will but what about the first gens with the 7 bolt? i got a 93 eclipse with a 7 bolt 4g63 in it and that thing is nice on power!!! it has a 5 speed and it will roast the tires right off if i asked it too but i am adding a turbo to it and leaving everything stock and just putting it up to only 7 psi so i don't blow anything...... would it do crankwalk on me if i did that?

No one can tell you if your motor will walk.

 

[eclipse2hotforu]

i know no one can tell me that..... but second gen 7-bolt 4g63 engines r known for crankwall cuz the bracket holes r alittle bit bigger than the bolts that fit in the holes and when putting alot of power in them or running them hard they r known to not hold the crank which makes it crankwalk (move) and blow the engine and i didn't know if the 1st gen 7-bolts were like that r not.....

First rule of owning a DSM: Never ask anyone about crankwalk.

Some get it, some don't.

Poorly adjusted clutch hydraulic systems are often overlooked when it comes to crankwalk, so make sure yours is completely disengaged when you're not on the pedal.

Asking about crankwalk is like asking someone on this forum if you have a nice personality and will anyone like you? We can't answer it because we don't know you. Same for your car. You can baby it, it still might happen. If you take care of every part of it and don't abuse it, you should be good, but it can still happen. It happened to my 6 bolt '90 AWD. Any engine can crankwalk, for lots of reasons.

yeah i would like to know about this 2, i thought that only 2gs where crankwalk prone. What about the 1g 7 bolts? are they as prone as the 2gs 7bolts? and if there not, why does no one ever talk about doing a 1g 7bolt into a 2g 7bolt? would that not acheive the same goal as doing a 6 bolt swap? and be alot easier 2???????????????????

well i'm sorry then... i just had a curious question its not like i was asking about if mine would i just knew they did it and didn't know anymore about it and was wondering what things make it wanna do that and if the 1 gen 7-bolt have ever been known to do that.... but i promise i will never ask that again just please don't tell

 

[clownface]

i still would like a answer 2 my Q, im being serious, i dont get it

 

[Agent Ezzard]

1. People have heard of 1g 7 bolts walking more than 6 bolts walking so why play the odds.

2. The only thing different about putting a 1g 7bolt in a 2g would be the flywheel so again why play the odds.

what do u mean why play the odds? i can't help it! its the engine in my car! if it goes then i am in trouble! and i can't do anything about it so i guess i'm screwed then huh.... but the thing is, i have never heard of anyone saying anything about 1st gen 7 bolts crankwalking and and the 6 bolts don't do it at all.... and if u read the info in the website that is in one of the few replys up on top it talks about how different the 1st gens r from the 2nd so i'm thinking that it won't do anything...

in my opinion u r right i think it would be easier cuz in alot of the websites that compare the two 4g63s when talking abotu crankwalk is the 1st gen and the 2nd gen 7 bolts and they compare how much is different on them which shows how the 2nd gens r the reason for crankwalk and the 1st gens aren't..... so to answer ur question i think people would rather have a 6 bolt then a 7 bolt in there 2nd gen cuz of the fact its a 6 bolt and not a 7 bolt and everyone gets worried that every 7 bolt will crankwalk when its not only if its a 7 bolt u have to worry about its what they made it in that u have to worry so yeah it would be easy and a good idea to put a 7 bolt in a 2nd gen just as long as it is a 1 gen 7 bolt

 

[eclipse2hotforu]

i meant to put what year they made the 7 bolt in

I don't know how long you have been around but to say that 6 bolts and 7 bolts don't walk is outrageous. Do not make statements if they are not back by some sort of proof. There have been more 1g 7 bolts walk than 6 bolts but the 6 bolts CAN walk. So what I mean by play the odds is if both 1g 6 and 7 bolts are the same swap then why do would choose a 7 over a 6 if the 7 has more occasions of failing than the 6? BTW my 7 bolt walked along time ago and now I'm on my second 6 bolt.

 

[clownface]

the reason i was asking this is because my friend wrecked his 94 GS with 4g63 7bolt and the engine is fine and i can get it really cheap, he just messed body up. And i cant find any 6bolts in my area, ive looked all over. Are there any differences with the 1g 6bolt and 1g 7bolt besides the number of bolts???cause if not i dont see why one would be more crankwalf prone then the other, other then just coincidence.

 

[eclipse2hotforu]

ok here is the deal on 4g63s.... i just found this out..... all first gen 4g63s, no matter if it is a 6 or 7 bolt r all the same except one has a 7 bolt pattern and the other has a 6 bolt pattern on the crank... well... when it got into the 2nd generation they started changing stuff on the 7 bolts and using just them well the chagnes they made were a bad idea cuz alot of there engines started crankwalking... so u r perfectly fine using that 7 bolt! and mine is fine too! so yea! its kinda sad how u can ask a question in here and end up finding the answer urself....

i didn't say that they didn't crankwalk i just said i never heard of any crankwalking... theres a big difference! and me and almost everyone i know that has a 6 bolt around here has never had crankwalk and actually almost all the 2 gens with 7 bolts around here haven't even had crankwalk either most of them haev a crap load of hp under the hood so i guess they r treating there crap right i guess but thats why i feel the way i feel

 

[Agent Ezzard]

Yeah... it's a sad world we are living in. And you cannot put a 7 bolt crank off a 1g into a 6 bolt block. Try it out if you are a don't beleive me.

umm why do i want too? i have other things to do like my g/f than to care or even want to try to put a 7 bolt crank on a 6 bolt cuz i already know they r different i guess u just misunderstood the way i said that both engines r the same

 

[clownface]

why are you getting upity with each other? I seriously would like a real answer to my question, cause i would like to buy my friends engine. my previous question:

the reason i was asking this is because my friend wrecked his 94 GS with 4g63 7bolt and the engine is fine and i can get it really cheap, he just messed body up. And i cant find any 6bolts in my area, ive looked all over.

The 6 bolt would be more CW proof. Change out the pistons with some 2g ones and put some 6 bolt rods in there and you'll be good to go for a turbo application.

 

[Larry L]

The 4g63 N/T motors are a bit different than the turbo's the trannies are also different. Also IMO I would never runs a heavier pressure plate than a 2500 due to the excess pressure putting your car into crankwalk. It is true any car can crankwalk but I believe that if you did a turbo set up on your ride you wouldn't have any problems. But if it is a real concern...Save yourself some money and get a JDM 4g63 turbo motor and do a swap that way...

 

[eclipse2hotforu]

ok i'm sorry i am getting mad... i'm just mad cuz its sad how when someone doesn't no something they jsut make what they think is a educated guess which is stupid when they jsut plainly don't know! but yeah thats what i thought! i know it wouldn't do much unless i started adding alot more power and adding more stuff to the tranny that would make it want to force it to crankwalk so thank u for that answer cuz that helps me out alot too!

 

[BoostinAWD]

Crankwalk has been blown way out of proportion!!

I'm seeing MANY 2g's with over 150k miles with the factory block still

 

[Groomz]

No one will ever make friends talking about crankwalk. These threads will go on for pages and people will argue dead topics and beat dead horses ( metaphor ).

ITS NOT WORTH DISCUSSING CRANKWALK!!!
( For your own safety )
Not trying to be mean or anything, but there can be some pretty ugly arguements between people for no reason. Lets all stay friends!

Crankwalk can happen to any car. Crankwalk is thrust bearing failure. Any car that has a thrust bearing can have crankwalk. Big semi's get it, even Honda's and Fords. Improperly adjusted hydraulic systems, failure of oil pumps, lack of oil changes, and heavy clutches are just a few things that *CAN* ( theoretically, not proven to apply to every car ) cause crankwalk. I have a 1995 2G 7 bolt 4G63 in my car ( which from popular opinion is the worst year for crankwalk ) and is still in specs on endplay. Go figure, my 1990 AWD 6 bolt crankwalked with 3/8 inch endplay, visible endplay. That was because of a sloppy rebuild.

Drive it smart, take care of it, and make sure everything is in order and you should be fine. If your 7 bolt crankwalks, then congragulations, you are now in the position of swapping in: a 6 bolt 4G63, a 6 or 7 bolt 4G63/4 stroker motor, or a 4G64 bottom end.

Sounds like an educated guess to me.

About those 4G64 7 bolt blocks... One has walked before when used with a 4G63 head and swapped into a GSX.

sounds liek someone doesn't know what they r talking about cuz i meant the bracket holes for the crank!! and thanx to the other guy who helped me about crankwalk knows alittle more than u cuz he told me if i add a turbo and don't add a pressure plate that is rated more than 2500 will make sure it won't..... cuz its the truth cuz if u understand engines!! u know that it makes sense that the pressure plate pushing on the crank hard enough will cause crankwalk!! but u know i give up on u and u can think whatever u want!! and thanx to everyone else who knew what they were talking about!! u guys r awesome
