motor break in hello, it is often said pour the last qt of oil down the distrib shaft hole. it seems to me that that should be done with the head off and distr shaft out -yes or no?
if the head is on and oil is poured down distr hole that oil will just go down valve shafts and pool above the piston tops- yes or no? thank you |
Re: motor break in In short, no. The distributor hole is sealed by the head gasket, all of the oil will end up in the valve chamber.
I'd say you have more odds of getting oil on top of the pistons if you have the head off and spill some. |

Re: motor break in What Ryan said. At least a qt down the distributor hole or into the valve chamber if the side cover is off. The oil will then get to the cam, cam gears and dipper tray.

Re: motor break in I poured the quart down the distributor hole in my rebuilt. No problems at all with this inserted motor. In the 5 yrs of running it it has not used a bit of oil between changes which is every 2000 miles.

Re: motor break in The reason you pour the last 2 quarts down the distributor hole is it lubricates the main bearings and cam bearings prior to start up.Without doing this your main bearings and cam bores can run dry for up to 30 seconds till the oil pump fills the valve gallery

Re: motor break in thanks to all--made sense to me and will follow guidance

Re: motor break in Remove the lower distributor shaft when poring oil down the distributor hole. This will make it a lot easier for the oil to drain down into the valve chamber.

Re: motor break in Contact your engine builder and follow there advice! If assembly lub was used it will protect the parts your worried about. With the spark plugs out cranking the motor over until oil flows out of the drain back tube, valve chamber is now full of oil, oil flowing to the important parts.
