OK, for all you MEK-A-NEKS out there, the Old Dumb Okie needs some HEP!!!! I want to install the Tell-Tale in my motor. I got all the parts and according to the link I posted I can drill into the Cylinder block behind the coil Brackets.
V-4 blocks
The V-4 configuration presents some interesting issues for locating the indicator outlet. Typically the V-4s run hot on the starboard side. That's because of a tendency to develop air pockets high up on cylinder #1. By adding the indicator outlet to the top of the water jacket above cylinder #1 you provide an opportunity to "burp" any air out of the system and fix this issue. On many of the '73-'77 V-4 blocks there's a cast-in round boss just perfect for locating the indicator outlet. If you don't happen to have that boss, you can go in through the top, just behind the coil brackets also.
My motor does not have the Cast-in Boss (Blue Circle) so I'll be drilling in behind the coil brackets. My brackets are located about where the green circle is. My question is, do you think I need to remove the Head so I can see where to drill the hole for the elbow nipple, or can I just center it in the block and drill till I break thru the wall? Not sure how far back I can go to drill the hole. I know to grease the bit so no metal flake fall down inside the hole. I'm NOT a MEK-A-NEK but I do have a Torque Wrench and the Service Manual so I think I can take it off and put it back on but I take the risk of tearing a gasket and or busting a bolt in the process. Is there anything else I need to worry about or be aware of. I hate to Mess with something that's not necessary, but I don't want to take the chance of drilling in the wrong spot either. I will make a jig to ensure I drill a straight hole and tap it properly as well.
All comments and advice are WELCOME!!!!
