Location: atlanta | !. It's my understanding that the oil pump to rear main uses no gasket or O-ring because they are both machined surfaces, is this true?
2. The 1961 poly 318 uses a canister type oil filter, the 66 poly 318 uses a spin on, my question is, when using the 66 parts to adapt the 61 poly 318 to use
the spin on oil filter, do I just need the center that unscrews or the plate underneath it also? 3. I noticed when I pulled the cam out of the 61 318 motor, the snout of the cam had a removeable ring behind the thrust plate, I assume this is how You a adjust for cam thrust end play, the 66 cam had the ring/step machined into it, and I assume You mill the retaining plate to adjust the end play, right, or wrong? 4. The bellhousing on my 3 speed 61 318 has two holes for mounting the starter, the starters I have found have three holes but just use two for mounting, I was to by a very knowledgeable person this will work with my 172 tooth flywheel and the 318's extended crank, any been there done that, or second hand knowledge?

Location: Perth Australia | Q1 I can answer as a yes and I guess any slight oil leak at that point wouldnt matter, a big one would
But my theory is, the main reason (stretching my memory here) is the bolts that hold the pump on also hold the rear cap on, so it would need to be torqued down, so a gasket on a main cap or a small (relatively) area like that might not be a great idea

Location: atlanta | Yep, makes sense, especailly since the rear main cap is 85 ft lbs, I'm sure it would "squish" a gasket out anyway, and the gasket also may end up in the oiling system. |

Location: Peoples Republic of Oregon | The 'ring' on the cam is simply the early design which changed for the 62 model year, along with a good many other details including the
bell housing bolt pattern, crank design and flywheel tooth count. There is no provision, or need, to adjust end play on a cam.
As to the starter, it may be that the same pinion gear will work on a 130 tooth wheel and a 172 tooth (change in overall diameter and tooth pitch)
but you should check the tooth interface/fitment on the bench before taking the time to install it since you run the risk of damage to one or both.
The oil pump does not use a gasket due to the (originally) very flat machined surfaces, same kinda deal as the exhaust manifolds. Use an accurate
straight edge to check. Minor imperfections can be dressed with some 600 emery paper and cutting oil as lube. |
