Ppsss! Ppsss! Ppsss!

That is the sound that the engine in my 66 Galaxie LTD is making! I started losing power, kind of jerking a little. I replaced the distributor cap and rotor, and set the points and the timing. It is still losing power intermitently especially after I have driven it a few minutes. I had head gaskets replaced a couple of months ago. Any other ideas? Your help will be greatly appreciated!

Re: Ppsss! Ppsss! Ppsss!

Thanks for your reply. It cranks and starts and runs great at idle. It only makes this sound when the engine is under load. It seems to be either a loss of compression or a vacuum leak, but it isn't just a steady hissing, it is more like repeated short sounds.

None that I can tell. Oil and anti-freeze both look good. Thanks!

Re: Ppsss! Ppsss! Ppsss!

Best wild guess I can think of. It sounds like compressing blowing by a spark plug or something. I don't know if a cracked head or leaking gasket could do this or not. Just my 1 cent worth.

Re: Ppsss! Ppsss! Ppsss!

how old is the exhaust? a plugged exhaust could do that with the noise being a leak at the manifold from the engine pushing the exhaust out anyway it can. this is more common with a catalytic converter falling apart internally but a mufflers baffles can float around inside and plug the outlet then at idle the piece falls back into place on the muffler floor opening the outlet. check that the spark plugs are tight too.

Re: Ppsss! Ppsss! Ppsss!

Would a plugged exhaust cause a significant loss of power? I am starting to think that this is the culprit.
