Resolved oh jeez, walking?

Heres a good thread on the differences between the two so you get an idea of what needs to be changed.

But I believe you would need a CAS, Flywheel and Clutch for a 6 bolt, some head work if your going to keep the 7 bolt head. Thats about it though and a tuning program to flip the cam sensor signal if need be for your car.

Ahh, another of those crankless non-crankwalking 6 bolts. No wonder everyone is swapping, lots of weight loss when you don't need a crank at all, unlike the 7 bolt.

since 1g 6/7 bolts are the same block(?) correct me if I'm wrong, can I just swap a 6 bolt crank/flywheel/clutch combo and the rest stated above as long as the block is not damaged, or am I just going to be looking for another block.

 

[Archer Fabrications]

They aren't the same block. If you are curious.

what about this then?

anyways back to the point, I guess which ever short block I get a hold of before mine completely craps out is what I will build.

If your motor has a crankshaft and a thrust bearing then it can suffer from crankwalk, it's not just a 7-bolt thing and its not just a DSM thing.

That's like saying that just because a small amount of men get breast cancer, it's not a women's health issue. It is a very legitimate complaint that the early 7 bolt dsm's have a higher chance of crankwalk than a gm ecotec. Crankwalk is as much a concern with 2g dsm's as door handles falling off, and bad ball joints.

I crankwalked, put new ACL's in and been about 7k miles and still going strong!

#### taking the crank out for a walk.

Its a funny vid guys should check it out

 

[93AWDDSM]

sorry to bring this back but I still have a significant amount of end-play for the crank (hasn't walked yet) is there a chance I can catch it now and throw in some ACL bearings and have the crank checked for damage and if everything checks out just stock build it? I have no plans on going past 20 lbs of boost at all once its rebuilt.

Talking about bringing it back . Are you still running the same motor that you were experiencing the "crank walk" symptoms with?

 

[BogusSVO]

I like King bearings. I have been using them in both 6 bolt and 7 bolt with out issue.

93AWDDSM, When you pull the main bearings out, check the thrust face of the crank.

If it feels stepped, or rough, new bearings will last a short time, depending on how bad the thrust face is.

If it is rough at all, it will just chew through the new bearing.

 

[93AWDDSM]

1sick_gst: yes it's the same motor still

BogusSVO: thanks for the helpful information, I will be sure to check that once I pull it!

question though, if the crank is trashed would that mean the block would also be unusable with a new crank?


EDIT: car walked yesterday. thread solved.
