Re: exhaust manifold leak: rough idle?
i have removed all the rubber hoses, valves, and vac lines in that system period, except the check valve on the head cross-pipe. there is one hole between the first and second cat that will need to be plugged, but somehow between my injection pipe ripping off and mud/rust, it has fully sealed itself and almost looks welded... weird. i'm wondering if the exhaust shop didnt weld it the last time i had it in, but that would be a PITA to get to. anyway, just make sure you either plug the line going from head to head OR leave the check valve in place, which is what i did. i'd like to pull that stuff off completely and plug the holes right at the heads but i'm slow to get anything done that doesnt help me put chunks of mud on my roof [img]images/icons/laugh.gif[/img] the only thing i have left to do is run some new lines for the EGR valve system, which is easier than trying to block off those TAB/TAD solenoids. right now i have that whole vac line segment plugged at the intake manifold tee, but i'm sure it would trigger a check engine light without the EGR working properly. mine has been on solid for 3 years now so i cant tell you for sure [img]images/icons/wink.gif[/img]
i have yet to block off the smog pump ports, and i went through some DEEP water today which is not good because i dont know how sealed its bearings are. i'm going to run a hose from the intake to the exhaust but as i recall they are 2 different sizes so you cant just slap one of the old hoses on there.
