My turbo kit came with oil lines to the central bearing. These lines do not show up on any of the turbo illustrations and there are no instructions. I noticed there is a small screw on the side of the block that seemed to provide access to an oil passage to the head. I removed the screw and cranked the engine and indeed oil came out. The fitting with the small screw threads into this hole and the fitting with the large screw obviously goes into the cam cover. I positioned the lower fitting to keep the oil line away from the exhaust manifold. This arrangement seems to work. (see the close-up p9cture) I will shorten the oil lines to make them neater once I am satisfied no modifications will be needed.
To complete the engine set up I made a coolant reservoir out of (mainly) one-inch copper plumbing parts. This provides a convenient way to fill the cooling system as well as a reserve water supply.
