Just got the call from the mechanic :(

[halflife]

changed the starter, started her up and no compression in 2 cylinders.<br />They said they pulled the valve cover and one of the valve springs was broken. <br />They said that they are going to change that and see if it fixes it.<br />Question is, if only one valve spring is broken then why is there no compression in 2 cylinders. My guess is my pistons are toast. They already started the valve spring change and said if that does not work then they have to pull the head to see. Should I waste time on labor removing the head if the valve spring does not work because I will most likely have to get a new motor or a rebuild. If i rebuild i will most likely be taking the motor to another shop.<br />What do you think<br />454 mercruiser magnum in a 1989 baja sport

Can't see how a broken spring alone would drop 2 cyl. I think you would be money ahead to just pull the head and inspect. There is more here than just a broken valve spring.

Why didn't you go to the other shop first ?<br /><br />I'd pull the head and diagnose fully.A rebuilt motor is a tad bit pricier than a spring replacement and a valve job.<br /><br />DHP

Re: Just got the call from the mechanic

What 2 cylinders are dead? could a valve or two have been wet and got sticky and maybe got bent.are any push rods bent.
