Y block question
Have a 55 yblock engine, replaced the original distributor with a 57/58 unit. Started the engine, no oil pressure, ratcheting sound. Appears the shaft from bottom of dist to oil pump was not engaging the bottom of dist. Does the round washer on the shaft hold the shaft in the proper location?? All help appreciated. Bill

Re: Y block question
Try to look down the distributor hole in the block and see what the top of the oil pump drive shaft looks like. (or on the bottom end of the distributor shaft of the one you took out)
There are two styles, one has a hex shape rod, the other older version is a flat & slot. It may be mis-matched with the distributor. The number of teeth on the driven gear isn't the same either, 14 teeth = '55 thru '64 and 13 teeth = early ('54) Last edited by dmsfrr; 06-12-2019 at 11:18 PM. |

Re: Y block question
My question for Bill would be, is the replacement "57/58" unit an original dizzy or a new rebuilt unit from FLAPS? If from your Friendly Local Auto Parts Store, then I would bet the distributor shaft is to short by about 1/4 inch and wont properly engage the driven shaft.

and, from the bottom of the driven gear to the end of the shaft. (1 inch) No gasket is used at the dist housing shoulder to engine block opening, if there is one there take it off. . Last edited by dmsfrr; 06-12-2019 at 11:14 PM. |
