Son in law runs auto shop. Told me job pays 3 hours to do plugs. “No way” to get to back plugs without pulling intake. I had never done it but invite him over to show him. Popped dogbone off, parked car on slope at end of driveway. Had to pull cowl brace off to get room to pull wires off. (95 DOHC vert).Long extension and all 3 plugs out in no time. I use a piece of fuel line with the new plug jammed in it to install new plugs. This assured I didn’t cross thread new plugs. Seated plug then tightened plug with ratchet. Gonna invite him back when I do the timing belt without a bunch of special tools.
