That is exactly what happened, Ross! No cotter pin and the lever broke the chain.

That is the third time I have heard of that. V8 owners: beware of rebuilt fuel pumps without pivot pin retainers. Safety wire or even just a little bent up piece of sheet metal under the mounting bolt heads will forestall this.

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.

Add a bit of oil to the right cylinders through the sparkplug holes and run a compression test again. Will tell if it is valves or ring.

Not sure there would be so much delay in oil getting to the right side to be noticeable but if that is the case, a loss of oil pressure could cause the tappets to collapse. That would result in the valves not opening as far as the left side so I suppose it could be possible the right cylinders are not getting the same volume of air on the intake stroke as the left side and is the cause of the almost equal loss of compression. If the engine has been run they should have pumped right back up though unless there is some kind of restriction in a passage or gallery.

Even if the lifters are collapsed the valves should still be closing. An equal amount of valve leakage would seem unlikely on all 4 cylinders to be causing the issue. Seriously doubt all 4 rings are leaking an equal amount either for that to be the cause.

The rocker cover is easy enough to pull to view the valve action. Perhaps you could verify if they seem to be moving a decent amount or pull both covers and compare.
