    Replacing Coolant Housing - Fuel Rail in the Way

    I am replacing my busted coolant housing (that the thermostat housing bolts to) and it appears that the fuel rail has to move half an inch to clear. Does that mean I have to go through the whole procedure for pulling the rail off, or is there a way to just massage it a bit for the clearance I need. StereoInstaller, feel free to post the sledge pic :D

    BTW I am picking up a 1/4" torque wrench today.

    I really didn't want to mess with the fuel rail, so here's what I did:

    The coolant housing slides out on 2 studs (see pic) that are attached to the head. I backed the lower stud out of the head with vice grips. That allowed the coolant housing to swing down away from the fuel rail & then slide the rest of the way off the top stud. Will be a little awkward to put back in, but worth it to leave the fuel rail alone.

        Oh yeah, and now for the tech help. Here is my recommendation:

        Considering the condition of your cooling system, I would bet your fuel system has a trashed o-ring or three. Fortunately, they are cheap, but kind of tough to find. If I cannot get BMW parts (fortunately, they deliver) I use NAPA.

        So, you can pull your fuel rail completely off with like 4 bolts, and while off, replace all 6 injector seals AND the fuel pressure regulator seal...not a bad idea to replace the fuel line as well (get BMW ONLY on this, trust me)

        While all of this is out, do your cooling passages. Like you didn't know that part, right?


        Otherwise:

          +1

          The fuel rail isn't hard to remove at all.. takes about 5 minutes. There are four 10mm mounting bolts that mount the rail to the intake manifold. After that, you can just pull the whole thing out.

          At least you had fun though :)

            Actually, I didn't know that. Can you post a link or explain?

              As in replace the gaskets/orings etc....the stuff you are posting about currently.

              How is progress otherwise?

                Progress is good. I'm trying to be throrough and do all the work recommended that goes along with the TB change, plus fixing the stuff I'm breaking due to ignorance and lack of a small torque wrench. The only task that probably needs doing, but I'm too chicken, is changing the front crankshaft seal.

                A good sign is that I'm starting to install some new parts rather than just take the old stuff off. My Bentley manual arrived so now I have torque values, spark plug gaps etc.

                I have spent many hours searching this forum (won't admit to being on the other one, nudge nudge wink wink) and discovered many hours of joy coming in my future to get my old car up to snuff.

                Thanks to all for the advice, help with parts, and um, moral support.

                    Do the camshaft seal and waterpump while you are there. You'll regret it later on if you don't.
                    Break the nut loose on the cam shaft sprocket before you take the timing belt off.

                    This is what it looks like with the sprocket off. Notice the gooy, icky mess? That is because I didn't change mine when the I was doing the belt.



                    Of course the whole engine is getting rebuilt now, so it doesn't matter anyway.

                      That's what you get these days. The new OE housing I bought a month ago also had two extra tapped holes. I grabbed a couple of universal drain plugs from Advance to fill them.
                      The car makes it possible, but the driver makes it happen.

                        According to RealOEM, the extra holes can be (should be) filled with a 14mm plug.
