7 bolts aren't "junk", they just need proper maintenance and in some cases good luck. I have a 96 TSi with 210,xxx miles with no crankwalk (knock on wood). There is a thread on here called "crankwalk in depth". If you read it you will see that 48% of all crankwalk cases are caused by dirty oil. Thats basically half of all cases due to poor maintenace. Other than crankwalk, they are great engines. Oh, dont forget the timing belt every 60,000.

the 7 bolt motors that you dont want are from the 95 to 97 talon/eclipse they manufactured the cranks wrong and they tend to crankwalk after a bit. if your 7 bolt motor comes from a 1g...you should be fine...unless you want to push some crazy horsepower out of it... i run a 7 bolt motor and its ben holding up good

The whole crankwalk issue is over rated. If theres more than 70k on the motor it will not walk. All cases I have heard of happened around 65k. 92 was the start of the 7 bolt motor and like said if its maintained well they are great motors.

Please do some research. My 95 awd got beat severely, over heated, run nearly out of oil and never walked. The few cases of crank walk that I have seen are typically 97 and 98 fwd cars. The crank has never been proved to be the issue, in face there has never been a definitive answer as to why it happens. I have seen 6 bolt automatic cars walk. It's an mechanical part, it can fail at any time regardless of the engine make or model. The best reason behind crankwalk that I have seen as of yet is the theory that Marco from Magnus came up with that particles clog the squirters and they stick open robbing oil pressure from the crank. Now I am not saying this is why it happens, but its the best I have come across. I have built several 7 bolts and I typically weld the squirters shut just in case this theory is correct, I have not had one fail from an oiling issue yet.

Well thank you all for your answers I think i`m gonna grab it then..I had a 92 gst and i had problems with it but i was young and never maintained it..Well i guess now i am gonna be the owner of this car .. Thanks again everyone for your help

7 bolt engines that came from 2g DSM's (maybe the 1g ones too. i don't know) have a higher compression ratio. The connecting rods aren't as strong as the 6 bolt rods but there are many 7 bolt engines with 350+whp. I would get under the driver's side wheel well and check the crank end play.

A simple way to check for play on the crank is to reach under the car by the crankshaft pulley and grab it and pull and push it. If it slides in and out a little, the bearings are worn and it might crankwalk. Sure grabbing the pulley and shaking it isn't an extremely accurate way of measuring end play, but who carries around the tools to get an exact measurement for end play?

The other way to check for crankwalk is to take the car for a test drive and take a hard left turn (maybe right turn. I can't remember) and if the clutch pedal doesn't come back up when you press it, it has some play in the crank.

I hope this helps.
