In recent months my 505 has been losing a little water and I can't see any leaks. No water in the oil either.
Now it's leaking slightly more.
I assume the head gasket is letting it through, so I'm replacing the gasket. The head was done a few years ago, but not THAT long. To prevent this occurring again I'm thinking of using Hylomar on the head gasket, though I've only done this twice before.
You guys got anything negative to say about this ?
The only potential problem I can see is that when I spray it on, it also goes on the thin metal rings which seal each liner.....right where all the compression is. Whereas I only want it to be where there may not be enough sealant-stuff already on the gasket.
It's a Sasic gasket with only a thin blue line of sealant running around it .....lots of circles around those areas which need to be sealed. The rest of the gasket has no glazing which might indicate a sealant....it is just plain grey gasket.
I guess the makers of Hylomar have formulated it to seal over the "fire ring" but I still wonder......
Perhaps just a THIN layer would be best ?
