Sarli Posted October 20, 2016 Share Posted October 20, 2016 Dear Gods-Of-Subaru-Turbo-Knowledge, please reply... 2Years ago I changed my turbo (05 OBXT into a VF52) and tuned it conservatively. TGV Bank 1 sensor failed, so needed to move the turbo to reach and change sensor. Those beautiful M10 bolts were put in with regular anti seize compound (gray permatex messy stuff), and that compound seems to have cooked in there, and became a rubbery stick crap... one bolt had to be cut off -- a nice 2 days wasted. How do I anti-seize these bolts properly??? I thought about Super Lube Synthetic Grease, as it is rated from -45F to 450F. Thoughts? Comments? Suggestions? (Wife's suggestion is to get rid of this wagon http://legacygt.com/forums/images/smilies/spin.gif... It only has 93k miles on it, and drives perfectly... and IT IS A MANUAL... so I'm trying to keep it.) Link to comment Share on other sites More sharing options...
Sarli Posted October 20, 2016 Author Share Posted October 20, 2016 Oh, to clarify, I'm asking about the bolts that attach the turbo to the down-pipe, as well as the bolts that hold the turbo to the up-pipe. They all had the same antiseize cooked crap in them. Link to comment Share on other sites More sharing options...
08SpecB_DE Posted October 21, 2016 Share Posted October 21, 2016 I've never seen anti seize become "sticky crap". A small amount to the first few threads on the bolts is all that should be needed. Link to comment Share on other sites More sharing options...
Max Capacity Posted October 21, 2016 Share Posted October 21, 2016 Here's mine from this week. Can't tell you haw many times I've removed and installed them. Never had a problem using Permatex anti-seize in the gray bottle. http://i185.photobucket.com/albums/x40/92Si/DSCN7354_zps5tm6cq2s.jpg Lat night I pull the PS pump. the bolts came right out and had the same anti seize on them from May 2012 when I put the ej257 in. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it. Engine Build - Click Here Link to comment Share on other sites More sharing options...
JF1GG29 Posted October 21, 2016 Share Posted October 21, 2016 I use copper anti-seize -- has never become sticky and is actually quite thin. Link to comment Share on other sites More sharing options...
Sarli Posted October 21, 2016 Author Share Posted October 21, 2016 While I never had any issues with that regular anti-seize either, it seems that the heat cycles of the turbo over the 2+ years in the same place, without removing it and cleaning + reapply, changed the consistency/performance of the regular gray permatex product. I'll try the copper anti-seize this time -- rated to 1800F. (JF1GG29!) Thank you all for the attention! Link to comment Share on other sites More sharing options...
Max Capacity Posted October 21, 2016 Share Posted October 21, 2016 Are you spraying the bolts with PB Blaster before you remove them ? I do. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

WahooNo2 Posted October 23, 2016 Share Posted October 23, 2016 make sure if you use the anti seize in the jar you mix it. mine tries to seperate into oil and grey goop Link to comment Share on other sites More sharing options...
JF1GG29 Posted October 25, 2016 Share Posted October 25, 2016 Definitely use PB Blaster. I've also have had good luck with a 50/50 mix of ATF and acetone. It's nearly impossible to use in a spray bottle, so I brush it on. There have also been times where nothing will do but a MAPP torch. Good luck!

Aannnnd... consider an alternative to PBB: Brake fluid. Disaster to paint, but nothing better on frozen bolts. Add impact device and heat as necessary.
