Removing Manifolds

[Keyav8r]

I think I read somewhere that it is possible to pull the exhaust manifold without removing the intake manifold. Well, it may be possible for someone but not for me. Got all the bolts and studs out and got the manifold wiggling around a lot, but not enough clearance to get it out.

That being said, I will be removing the intake to get the exhaust off (will also make it easier to re-install and as someone said it will give me a chance to clean the gasket surfaces better).

First step - buy or borrow the tool for dis-connecting the fuel lines.

Second step - figure out how to dis-connect the throttle body linkage. Does anyone have any tips/how-tos/ photos on that? If not, i can un-bolt the throttle body and the throttle cable/linkage bracket and lay it all to the side.

Speak up, O Great MJ Gurus! Share with this unworthy one your secrets.

It's the other way around.  The intake an exhaust share bolts, except the exhaust has two that are just for it.  Plus... there's a big pipe (EGR) connecting the two manifolds anyway.

 

But, removing the exhaust manifold without removing the intake would be a lot like trying to change your spark plugs without opening the hood.  Removing the intake is nothing.  Just remember where everything goes.  I've pulled a 4.0 out of an XJ without even disconnecting the fuel line, just got everything else off and moved the whole thing out of the way.  The accelerator cable should just pop right off the throttle body, or you can unbolt the whole thing from the manifold.

Remove the air cleaner box to make it easier also.

Geonovast - Getting that EGR pipe loose at the exhaust manifold was a bear. PB Blaster, Pipe wrench and 18" cheater finally got it done. I think my shoulder will eventually go back in place. I'm going to try to just finish unbolting the intake and move it over with the lines still connected. That should give me enough room to clean everything up and replace the exhaust manifold.

 

cruiser54 - I already had the airbox off to make room when I replaced the timing chain and sprockets. I took the master cylinder and booster off to make more room to work on the manifolds. I've got a '96 booster and MC I was planning to install at some point, so might as well do it too while she's up on the stands.

not to thread jack but here goes.

 

i need to replace my exhaust mani too. that said, i am only a shade tree machanic and was wondering the obsticals i will face. i will probably have to pull the head cause the front and rear studs are snapped off. i could possibly get a drill on the front but don't think there's enough room to fit the drill in the back stud. it's am 87 2.5. any tricks or heads up would b greatly appreciated. will i need to pull the air box, throttle body and all the linkage off? or can i just unbolt from the intake and move out of the way. don't mind saying, i'm a little nervous of screwing something up.
