    Removing intake manifold questions

    Guest-only advertisement. Register or Log In now!
    OK, I need to pull the intake manifold due to a leaking valley pan gasket, which is covering the front of the motor in oil.

    The DIY pages I've looked at say to remove the injectors and rail first-could I just disconnect the fuel line and electrical connections and leave everything in the manifold and remove as one piece?

    Will I need new manifold gaskets or can I reuse what's there?

    Thanks!

    I don't think you can get to the manifold bolts with it on. It's really a simple job to remove the fuel rail, 4 bolts and some pulling. Why not do it right just to make sure you don't accidentally damage something? You should order some pointless caps though because I bet you will have a few missing/broken. And you need to replace the intake gaskets.

    Also the process of getting the plugs in the front of the engine off is a PITA! You will by doing a little man handling on the manifold at during that.

    Agreed... do it right cause you not going to save any time trying it another way...

    The plugs...


    This helped me getting them loose, be very careful those plastic clips and vacuum lines will break

    This isn't in any DIYs I've seen but before you pull the manifold try and clean as much dirt and crap as you can from around the edges cause sand and crap will fall into the open valves.

    It's not necessary to remove the TB say, if you were just to put in some spacers right? I read the one diy where the guy takes it off but I think it's just because he replaced it with a new one?

    my car needed to have its valley pan gasket replaced prior to me buying it, and I have heard of at least one other with the same problem. I'm wondering if it will start occurring to others more frequently or if these are rare occurrences.

    To the OP, yes the fuel rail needs to come off. It pops right off, just lift straight up gently, it's probably the easiest part of the job.

    The TB can stay attached to the IM unless you are replacing it with the JHM IM & TB.


    enjoy being hunched over your engine for awhile.....I know my back aches just thinking of having to pull the IM just to begin replacing the valley an gasket
