Hello segeorge982,Need to express a little frustration. I'm not naming the machine shop who did the work.
Car hasnt moved since Sunday. I still don't trust that all the leaks are solved so I poke my head under it every day on my way in or out of the garage. Last night, 4 days after last being driven, there was a small new puddle on the floor. Coolant. Damnit. Dripping from the access cover between the engine and trans. Double damnit.
Checked the previous culprits, water pump connections, thermostat, heater hose. All dry. Friend says maybe its the core plugs, I blow him off and go inside for the night. Jump on the FE Forum and read about core plugs this morning. Ah crap, I bet the machine shop who did the block work, who i asked if they were familiar with FEs(theyve been around since the 1950s) put 3/4" plugs in instead of the 49/64".
Call machine shop because my receipt just says "Brass core plugs" no part number, no other information.
'Sir we used melling part number MPE-110BR'.
Me: " Thats a 3/4" core plug, too small for an FE"
'This is what comes up when we search for core plugs for a Ford FE"
Me: "Well that sucks, because its the wrong size"
'Let us go do some research and we'll call you back'
I'm still waiting for a call back. but it seems ive got 2 options:
1) Band Aid fix with stop leak and cross my fingers, toes, and anything else that a plug never pops out while I'm driving
2) Pull the engine and replace all 6 plugs
I'd love some feedback from this group on what you recommend. I really dont want to go down the path of stop leak but am not looking forward to pulling the engine.
I went through the same thing with core plugs on an FE. I used an engine builder who raced these engines back in the late 60's and naturally I thought, well he must know what he's doing. I couldn't have been more wrong if I was the captain of the Titanic and thought, well it's just a little water and it'll be fine.
Not only did I have to educate him on the correct core plug size, but on the second block I asked about one of the core plug holes in the block and being really pitted and if it needed to over sized. He said nah. Well the damn thing leaked in the car. Not only did I have to pull the engine again, but I had to completely dis-assemble it and take the block back down to have the one core plug hole over sized to clean up the pitting.
That's when I quickly learned to never trust anyone else doing the work and double check everything. It doesn't matter if they or anyone else says they are king and have been doing this for decades.
If your car isn't meant to be a trailer queen and actually driven, then just do yourself a favour for peace of mind and change the core plugs. Do not use radiator stop leak as it just has a propensity to gum up expensive and or hard to replace heater cores and radiators. It's like using stop leak in a transmission or power steering system. It's a temporary stop gap measure that just causes more expensive work later on.
Cheers
