Re: 1955 Packard Caribbean Timing chain replacement manual

So, after the chain was replaced and obviously, fuel pump (BTW, it has new rubber diaphragm and I can use regular gas, right?), a loss of power was noticed. These are the results of compression test:
LEFT BANK
1 - 110
3 - 105
5 - 110
7 - 110
RIGHT BANK
2 - 50
4 - 75
6 - 75
8 - 55

Before the compression test the car was driven around 2mi after chain and pump replacement.

Prior to the chain change, the engine was cranked frequently, before the problem was found. All this time oil pump didn't work and there was no oil pressure. Can the problem be in hydraulic tappets in the right bank, since they are lubricated after the left bank?

I would appreciate any thoughts and suggestions... Big hope is not to take the head off...

Thank you!

Val.
