I'm not sure about the transfers. If they come near enough the coolant jackets. Sent from my SAMSUNG-SM-G891A using Tapatalk Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted July 8, 2018 Report Share Posted July 8, 2018 Transfer or boost port would be my guess if something went through. How does the decks of the cylinders look? What steps and prep did you do for glue to stick and most importantly how long did you let it set up before pushing air in. If sealant isn’t 100% cured it will push out very easily under pressure Quote Link to comment Share on other sites More sharing options...

Toybreaker Posted August 1, 2018 Report Share Posted August 1, 2018 is the top of the cylinders flat? are the cool head components flat? Start with the easy shit first...... Quote Link to comment Share on other sites More sharing options...

ZillaFreak Posted August 2, 2018 Report Share Posted August 2, 2018 It isn't needed and you shouldn't use anything on them. Quote Link to comment Share on other sites More sharing options...
