Good morning, as said I have oil coming down the back of the block. At first I figured pan gasket, snugged them up , but closer inspection showed backs of heads wet, earlier she would not leak A drop , but after the past couple of runs, I park and there will be 10 - 15 drops worth coming of the starter some blows back and hits the "Y" pipe. any common areas I should concentrate on ? thanks for your help, in advance

Justin,

Run your finger along the seam of where the cam cover joins to the head as and where you can and check for signs of oil wetting.

Once you have eliminated the above and assuming the oil is not leaking from the sump gasket [also common] then the only other obvious spot at the rear of the engine would be the crank oil seal although not sure whether that would have the capability to migrate forwards if that is what is happening [hits the starter motor and runs along it until it drips?].

thanks for the reply. I've ( I think ) ruled out the pan gasket. It does look wet but its coming from higher up. Would running it hard, not ridiculously, but giving it some, create pressure anywhere which would cause a leak?

Seems you did not understand my suggestion- look for signs of a leak at the cam cover gasket face. Just run a finger along the sides and see if you find any obvious wet spot[s].

There is a hole machined into the front and rear of the cylinder head in line with each camshaft. The driven cam sticks out of one of the holes in each head. The other six holes have plastic plugs with O-ring seals on the original installation. The O-ring bake out and turn to hard plastic.

You can replace the O-rings, or you can install the later superseding plugs that do a little better job of sealing the oil.

It is a real PIA to replace the rear plugs or the O-rings on them, but it can be done.

Thanks WallyP. Does this apply to US MY 86.5 engine?
