RV mechanics worked on my 460 before I bought it.....they did not clamp the hoses in my A I R system which I blew off climbing in Nev. Every since then it blows manifold gaskets and eats plug wires every 250 mi......
why would the damaged AIR system cause this.....everything was perfect till those hoses were blown off....
any ideas......

Tom, your 460 should not have manifold gaskets. It came from the factory with none. The gaskets were probably installed to seal warped manifolds. Remove the manifolds, take them to a machine shop and have them surface ground. Then clean all the old gasket off the heads and install the manifolds with out gaskets. As with most 460s in motorhomes, the right rear manifold bolt will eventually break and start leaking again. The permanent cure is headers.

sorry to disagree,I have seen lots of 460 engines come from Factory with gaskets and they(gasket) also have a built in plug wire heat shield
Yes you have seen lots of PRE-EFI engines with exhaust manifold gaskets. BUT we are talking about a 1988 and later fuel injected 460.
So your observations do not apply to this conversation.
