    Tiny Vacuum Line the Runs Into Firewall That Controls/regulates

    So this problem seems to plague a lot of - Vulcan engines. There are a lot of places where a vac leak can occur but this one seems to stump people. My car was exhibiting the first two and was probably on its way to the third. After spraying starter fluid and checking all vacuum hoses I couldn't find any leaks. Then, while searching online, I found a topic on the other site that explained this problem and I decided why not put up a howto here? Before starting it's always good to make sure you have the correct engine only - engines have this part.

    The engine should look like this: You will need the following tools and supplies: Socket extension s at least 3" long. The part in question is this thing here red arrow: I will be using the former as it seems to be more descriptive of its function. To start, first remove the top piece of engine cowling on the passenger side by removing the clips - be careful! Use the screwdriver to help pry them off yellow arrows in pic above - 1 clip is out of frame.

    Also be careful of the vacuum hose marked with the green arrow. Don't break it or the car will have a fit I believe it controls the evaporative emissions system. Next you must remove the three screws holding the lower cowling on see yellow arrows in pic below.

    This is where a socket extension would come in handy as there is very little space between the cowl and the metal under the windshield.

    Now that the cowl is removed you have access to the screws holding the IMRC on, as well as the PCM and the cabin air filter under the windshield behind the strut tower. Disconnect the wire harness to the IMRC. It has a small push clip on the firewall side. Push it in and pull the harness off. You should be able to do this with your thumb and index finger. The lower one might be a tad difficult to reach.

    Remove the screws and pull the IMRC out. Mine fell out see pic with very little effort. Not good for a vacuum seal! Now, use the screwdriver to carefully remove the old gasket. Once out of the groove it should slip right off.

    Now you need to remove the gasket from the donor oil filter or if you have the OEM replacement just grab that and skip to the part about installing the new gasket. The new gasket should be the same size around as the old one. If it's thicker around like mine was you will need to cut it so that you can get the IMRC back in the manifold. Next, slide the new gasket on the part and seat it in the groove.

    If it doesn't sit flat it might need trimmed or you might need a slimmer gasket. It might be a good idea to lube the new gasket before reinstalling the part with some sort of grease or lubricant not wd40!! I used heavy weight gear lube as it was all that was available. It might take some pressure not excessive! It means you have an air-tight seal.

    Now all you have to do is reconnect the wire harness and reinstall the cowling. The car might drive funny the first time after this fix but that is because the fuel trims are now incorrect. The computer will adjust them over the next few times you drive the car.
