this is a 7 bolt, i got it machine and assembled it with an SBR 2.3 stroker kit. the engine doesnt have more than 1000 miles on it.. not even broken in.. could my crank have really walked already? i have a 4g64 crank, and a machined 7 bolt block.. would that not eliminate crank walk?

ideas please!

DAmn thats messed up. The 7bolt sucks balls!!! Its possible to have walked that quick!!! Man just go get a 6bolt, dont waste time with the 7bolt!!!

Are you sure your oil pump sprocket didn't just come loose? Have you dropped the pan to check out the bearings? Did your actual crank sprocket hit the timing cover too? Its hard to tell from the pics, pull off that dampner and take another pic for us.

Dude your crank did not walk your oil pump retaining nut came off and pushed off through your timing cover it was not torqued on properly. who assembled your bottom end?

it looks like the oil pump pully came off where is the nut that holds the oil pump gear on at?

damm bro.. u should have went threw all the bolts with a torque wrench when u recived that shortblock.as stated above, the only thing that happened there was that your oil pump sproket came loose. just tighten it up with a torque wrench.

well i went through a crank pully already, it totally ate into my timing cover! so i replaced the crank pully and thats the reason i agree with you guys on the oil pump nut:

now that i think about it when i was putting it all back together after replacing the crank sensor and pully last week i remember telling myself not to forget to torque the oil sprocket nut down because at the time i had just put it on with my hand.


REGARDLESS -

before the oil pump nut deal my crank pully STILL had walked into my timing cover and tore it to hell. i know for a fact it was put on correctly. what would give it the extra space to wear into the timing cover? i put it all back together correctly, the BS sprocket, sensor plate, timing sprocket, and then pully with spacer.

Did you bother to check the endplay on the crank while you were putting the motor together?

Crankwalk isn't going to cause something to walk that far. We are talking thousanths of an inch when a motor let's go. Sounds like shady motor building a lot of forgetting to tighten stuff.
