Abe Posted May 4, 2014 Report Posted May 4, 2014 Ready to put my head on and pow see a very small nik/ding in the cylinder and head mating surface right next to the bore. Does this need attention or long as it passes leak down go with it ? Quote
sleeper06 Posted May 4, 2014 Report Posted May 4, 2014 The oring should sit a lil past that if its bothering you put a small very thin dab of copperkote or threebond, ultrcopper, leakdown and youll be good I have seen alot worse than that Quote
Nieskes Posted May 4, 2014 Report Posted May 4, 2014 I had that once and it leaked like crazy, take some jb weld or epoxy and smooth it out as best you can. Quote
trickedcarbine Posted May 4, 2014 Report Posted May 4, 2014 I would assemble it and see if it seals up. If not, it's time for some epoxy/tig and a lapping Quote
Abe Posted May 4, 2014 Author Report Posted May 4, 2014 Just my luck , and this is a brand new cyljnder. Quote
Nieskes Posted May 4, 2014 Report Posted May 4, 2014 I would assemble it and see if it seals up. If not, it's time for some epoxy/tig and a lappingWhy not just fix it before assembly? Why take the chance? Quote
trickedcarbine Posted May 4, 2014 Report Posted May 4, 2014 (edited) The nicks on there look so friggin minimal I doubt they would even make an issue due to their location as well. It only takes a few mins to drop a head on and another few mins to make sure it's sealed. If it doesn't seal then deal with it. But if it ain't broke don't fix it. By no means am I saying to fully assemble it and assume it's fine, then fill it up with fluids and see what happens though. Just check it on the bench and see what happens.

RadarRacing Posted May 4, 2014 Report Posted May 4, 2014 Where that is shouldnt be any kind of problem. I would just put a dab of whatever sealer you choose on that spot and assemble, check. I bet its fine. 1 Quote
Tedder Posted May 4, 2014 Report Posted May 4, 2014 That's not bad. I've had worse seal with no problems. From the picture I don't think you really need to bother but if it were mine and it had a sharp feel to it I'd VERY carefully take a small file and just touch it enough to take the edge off. Quote
Abe Posted May 4, 2014 Author Report Posted May 4, 2014 Picture may even make it look worse than in person but I'd rather be safe than sorry, just seems 6psi in a leak down may not show problems that 170+ may while running. At least that's what my noodle is thinking Quote
Tedder Posted May 4, 2014 Report Posted May 4, 2014 You're correct that a leakdown test won't be comparable to actual running conditions but I think you are way to worried about that little dink. It's going to be OK lol - Put her together and go have fun! Quote
