I was looking through a hard copy of something I had printed off a webpage, some chap rebuilding his SD1 3500 V8, I forget now the website from where I got it as I've had it for a while, but anyway, he goes on to explain the extra holes he had drilled towards the front of the valley through into the timing chain area to provide extra oiling of the chain drive (he had fitted a double chain drive setup). The photo he had shows the valley looking toward the front of the block and two arrows pointing to the holes he had drilled at the low point where the oil comes down from the front of the cylinder head. So I was wondering (as I am at the stage of fitting the valley gasket and manifold soon), if this would be a benificial mod, or is there enough oil as it is for lubrication of a roller chain and steel gear set up as I'm replacing the standard chain and camshaft gear.
Thanks in advance,
