Spark Plugs..Starter motor

A myriad of tiny obscured bolts secure the intake manifold to the engine.. these must be removed before the manifold van be moved to replace the rear 3 spark plugs.........Strange thing is the plugs being of the long reach variety have about 11 threads on them, funily enough it only takes about 6 turns to get them out, I did not notice this till I tried putting the first one back in again.......wierd for sure.....
I had bought a replacement starter motor to instal also. I noticed afterwards that leaving the intake loose gives a bit more room to get the motor out. When re installing the starter motor do not forget to re attach the ground wire to the front bolt of the two required to re attach to the block........
Good luck, the old plugs were about 6 thou too wide but looked reasonable.however I installed 6 fresh ones and gapped them to a loose 50 thou. engine seems a bit more lively now for sure....
