After 15 years of good service my '66 MGBs began to show slightly
diminished oil pressure. I decided it was time for a rebuild. I stripped
the block sent it to a well reputed machine shop to have all the machine
work done. I reassembled the engine with new parts and dropped it back
in. I filled the engine and oil filter with oil. Without the ignition
plugs installed I turned over the engine, no oil pressure at the gauge.
I removed the hose to the oil cooler to see if oil was pumping through.
With the hose disconnected and the engine turning over no oil came out.
I started to think about what I could have done wrong. I thought about
installing the new oil pump wrong but I think it only goes in one way.
Perhaps the machine shop did not replace all the oil galley plugs. Then
someone told me that it is easy for air to block the system and keep the
pump from working. If this is true are there tricks for priming the
system? Or are the other mistakes I could have made that would create
this problem. I really need help.
Thanks in advance,
Graham
