k31th less WHY; more WOT Site Developer 29,047 Member For: 16y 8m 12d Gender: Male Location: Melbourne Posted 31/10/24 04:16 AM Share Posted 31/10/24 04:16 AM looks like rust, e.g. coolant ingress... which could be caused by a bunch of things but depends on the entrypoint more than anything... but I'm not an expert by any means...

That coolant ingress you speak of is through the bore, at least it looks that way to me. Link to comment Share on other sites More sharing options...

All I'm going to do for now is drain the water out of it so it stops leaking into the engine. When my new shed is up I'll pull it down for a closer look, but that's a few months away. I might get excited before then but unlikely. Link to comment Share on other sites More sharing options...

With any luck another 2k barra. Sweet as mate, turn her down a few notches and it should last more than 10 minutes lol. Link to comment Share on other sites More sharing options...

It's another head gasket as well unless you can reuse it being a fire ring? Spray some inox or oil in the cylinder if leaving it otherwise maybe pressurising the cylinder would be easier than the coolant system to see if air enters the coolant or vice versa if you can pressurise the coolant system without killing the radiator. Not sure you could apply enough pressure for either but I'm just spit balling as it's becoming the never ending story...it has been great for the knowledge department but your back, bank account and sanity is what takes the toll!

Tom Tucker Donating Members 669 Member For: 5y 5m 21d Posted 31/10/24 07:49 AM Share Posted 31/10/24 07:49 AM Maybe water/meth injection had a role to play, since it can't be compressed? Who knows Link to comment Share on other sites More sharing options...
