6 cylinder diesel turbo Cummins engine, 1 end port has been blowing for years (how long ive no idea, I bought it this way). I have fitted a new Manifold as they are known to warp at that end, but even with additional gaskets on that end port its still blowing a little

Now I know the answer is replace the head, but thats not going to happen unless it needs to come off for a more terminal reason

Are there any sealers, putties etc that are good for this kind of thing?

Thanks
