I heard there was a TransAm that required the motor to be lifted to change a plug. Not sure what year it was. I had a 79 that was tight but doable. That car was a ton of fun. Canadian model. 401 with no emissions on it.I once had a car that you had to pull and raise the engine to get to the bottom plug. Manufacturers don't care about stuff like that. In fact they delight in it because their dealers can charge more money for repairs.
Yours is an easy peasy simple repair...
Actually, upon further look I'm still not sure you will have enough clearance. Yikes.You don't have enough clearance for an open ended wrench of normal length, find an open end wrench that will fit the plug, make it your permanent spark plug wrench by cutting it down real short, use a flat head screw driver or something similar as a lever against the wrench once you get it in there to loosen it. Should be no problem after that.
I have 3 Sea Kings and all have the same affliction. In each of mine, the lower cowl has to be removed to access the lower plug.Open end, box end, offset, crow foot, 13/16 sockets of all types... nothing will reach in there. This is not easy peasy until someone who's done it tells me how.
On this one it looks like the lower cowl is a one-piece 'bucket' that's sandwiched between the powerhead & upper leg....One has a split cowl and comes off easy. The others have a bolt in one place or another that allows the cowl to move backward. None of the 3 require removing the powerhead to get the cowl off...
That actually might work. You're describing an O2 sensor socket and I have one I can try. It's 7/8 so it might slip, or be too big to fit between the plug & face of the head but it's worth testing to see if I can get it down in there.You are definitely going to have to make a tool I think. What if you got a cheap spark plug socket, cut a channel out of it the width of the spark plug insulator that way you can slip it on the plug. THen you could use vice grips on the socket further out away from the cover. I dunno, but I bet you will figure it out eventually.
Also, unthread the wire spud. It gives you wrench clearance. Then thread the wire spud back on.
Yes.The little terminal at the top? I'll try--every little bit helps.
