turbo oil return line

[neilb]

Hey guys quick question That I hope some ones knows...

I have a non-turbo 109 block that Im converting to a turbo charged type. I need to drill and tapp the oil return line fitting in the front of the block. Does anyone know what size that hole is? and is it metric or standard? This is the last hurdle to get my block assembled!

Thanks

I have the fitting for the block and oil return line if you need it.
