oil pump chain was broke. My chain after pulling the valve cover
was still intact and the plastic that holds it had broken teeth.

I thought maybe my valves wern't bent but accoring to the mech he said 4 on left side were bent and 2 on the other.

He said there wasnt much oilmat the top and says the chain component s must have broke cause the oil pump chain was giving it oil.

Does that sound right?

Plus do you usually pull the engine out to do a valve job? and chain?

He's says it will be easier.

Thanks for your comments
