Rebuilt a 455 olds and on first start there was no oil pressure. Pulled motor to see if the new oil pump was bad but it seems to be working fine. Pumping oil all over except for to the oil pressure sensor. Not sure whats wrong. Can anyone help me by giving some directions to look in???

 

Check for missing oil plugs in block-two in front at timing chain area and one in the rear in the distributor hole area. In is not uncommon for the rear one to be overlooked and not re-installed when reassembled.

 

Ok ill check that out. Thanks

 

Front two are missing. Thanks alot

 

I think one of the front two is supposed to have a hole in it to oil the fuel pump eccentric/timing chain, the rear one by the distributor is also supposed to have a hole in it

 

Yes and I believe the holes are 40 thousands in diameter.... TYedd
