sketron1 Posted March 27, 2016 Share Posted March 27, 2016 So I've pulled apart my vf40. The car has 130k miles, stage 2 for maybe 10k, meticulously maintained by both the previous owner and myself. I've got everything apart when I notice a crack that doesn't extend completely through wall. http://uploads.tapatalk-cdn.com/20160327/c3de2b1e938ca50d29c5ccbc1446846f.jpg http://uploads.tapatalk-cdn.com/20160327/fdb99805c02cbf585c6b143420409a41.jpg This is my first rebuild, and I have seen something about boost creep with these models. Is this the area that can be smoothed out to help prevent boost creep? Sent from my Nexus 6P using Tapatalk Link to comment Share on other sites More sharing options...
sketron1 Posted March 27, 2016 Author Share Posted March 27, 2016 Here's the bearings after 130k. Light scoring on the OD of one, but not bad for the mileage. http://uploads.tapatalk-cdn.com/20160327/41e3601bfd3d3ebf994d605ab89dcf07.jpg http://uploads.tapatalk-cdn.com/20160327/c781bf4b120508846172425573317956.jpg Sent from my Nexus 6P using Tapatalk Link to comment Share on other sites More sharing options...
iNVAR Posted March 27, 2016 Share Posted March 27, 2016 You're not going to have to worry about boost creep on a vf40. Link to comment Share on other sites More sharing options...
sketron1 Posted March 28, 2016 Author Share Posted March 28, 2016 About the crack, any better ideas other than blend it out? It's apparently enough wall thickness since the crack hasn't propagated through wall. Sent from my Nexus 6P using Tapatalk Link to comment Share on other sites More sharing options...
fahr_side Posted March 28, 2016 Share Posted March 28, 2016 Blend it out or ignore. Nothing is going to happen. Sent from a device using some software. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.
