Metal_man_Rob Posted February 22, 2023 Report Share Posted February 22, 2023 So you think the leak is coming through intake? It feels like it’s coming from the cylinder bolt where that divot is. But maybe your right about the intake leaking. I’ll try it out. Thanks man! Sent from my iPhone using TapatalkJust double check. If it is an intake Leake, it will be a easier to deal with. But it would be hard to mistake an intake leak for a leak from the cylinder mount. But it won't hurt to double check.Sent from my SM-S908U using Tapatalk Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted February 22, 2023 Report Share Posted February 22, 2023 Either way~ coming from stud hole or intake hole... it's a gasket not sealing. Dano/ hopped called it. I'd do what loco said 1st, since it's easier & use shorter intake bolts & sealant. If that doesnt seal it ( let it set up before retesting) then its your base gasket. I'll bet intake will seal it tho Quote Link to comment Share on other sites More sharing options...

If that divot has raised the material where the nut seats, then it would make sense why the base gasket would fail there and why air is allowed to seep out from that spot.

locogato11283 Posted February 22, 2023 Report Share Posted February 22, 2023 If it’s coming from under the nut, put 1211 inside the nut and tighten down. DM cylinders will leak there if you don’t seal the nuts. It’ll seal. Quote Link to comment Share on other sites More sharing options...

Sent from my SM-S908U using Tapatalk That "divot" is the end of where they drilled to make intake bolt holes. It stops right there. If the nut was torqued properly the base gasket would seal ( As much as they normally do, I always use some kind of sealant on base and intakes) could it still be there, yes. More than Likely, it's the Reed gasket and sealing that, will stop it from traveling down that threaded hole, and out of that "divot". Tho it looks like he has it tore down, the reed gasket is easier to fix & retest. 2 Quote Link to comment Share on other sites More sharing options...

JPL3 Posted February 23, 2023 Author Report Share Posted February 23, 2023 Thanks for all the great advice fellas! I have new gaskets on the way for intake, and coolhead. Are there anymore seals I should replace while I’m at it? New at the whole banshee air leak issues lol Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

New at the whole banshee air leak issues lol Sent from my iPhone using TapatalkStart with getting new gaskets for the reed blocks and intakes. I always use a very thin film of oil and heat resistant RTV on both sides of each gasket. So do that with the intake and reed gaskets and do another leakdown. If it leaks from that hole again, take pictures of the bubbles. Also use shorter screws so they don't contact the cylinder again.Sent from my SM-S908U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
JPL3 Posted February 23, 2023 Author Report Share Posted February 23, 2023 Okay got ya man. Thanks again! Gaskets should be in today so hopefully will get to it tonight or tomorrow Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
