Well, the telltales on the V4s are usually tapped into the exhaust manifold…But, I don’t know if there is enough meat there on an older model, and I sure don’t want you to pull that cover off…
I hear what you are saying about the starboard bank, perhaps placing a small tap up there would make sure air is bled out. But, again, I just don’t know where there is enough meat to make some decent threads up there. Use a small diameter thread elbow/tap to get the best bite. You will want to use the little plastic restrictor found on the newer engines in the pan as well. Allowing to much water to escape is kind of like bypassing the thermostat and might leave that side running cold at idle. I would be very careful choosing a metal tap/elbow, dissimilar metals could cause the aluminum around it to erode/corrode…Better off using the cheesy plastic elbow found on newer models, sealing the threads with something strong…
