Hi All,
Does anyone know if the 2 bolt holes in the front of a 350 block go to an oil passage, the holes are on the front of the block by the fuel pump, below the alternator.. I have an oil leak that does not show up until you drive the car on the highway.. It can idle all day and not a drop, The engine gets real wet around the fuel pump and I cant find this leak, I have checked front seal and everything I can think of.. Anyone know about these holes please let me know.. Thanks

Bad,
Yes one of them does but ... make sure the bolt you put in it is very short, no more than 1/2" long. The hole goes into the passage that the fuel pump pushrod goes through and if you put too long of a bolt in it will make a mess

A bit of trivia on that leaky hole on the front of the block by the fuel pump. The factory actually put it there for a purpose....other than to get on your nerves. [img]graemlins/angry.gif[/img]
If there is ever a need to change the fuel pump, the short bolt that plugs it from the factory is removed, and a longer one is threaded in until it makes contact with the fuel pump push rod. You can then R&R the fuel pump without having to do any slight of hand ot keep the push rod in place.
Once the fuel pump is on, the shorty is swapped back in place for the longy and you're done. [img]graemlins/beers.gif[/img]

Thumbs up

Three-eights inch diameter, 16 threads per inch National Coarse, 3/4 inch long hex head bolt.

When changing fuel pump on the side of the road, and you have no bolt in toolbox, use the pass side bottom water pump bolt for locking the pump rod. Finger tight, then do the swapout, replace bolts.

I'll probably catch alot of flack on this choice of bolt, but, if I remember correctly, no coolant came out. Maybe I didn't have coolant in it at the time..........so long ago.

My '69 350 has a bolt in the top hole, but not in the bottom one. Is this correct?

Thanks.
