Repair Summary The following article provides detailed instructions on replacing the intake manifold gaskets in a BMW E46 3 series car with the M52 or M54 6 cylinder engine.Įven though we have used a BMW ci to perform this installation, this article can be applied to any BMW E46 3 series vehicle with minor modifications to the steps below. Please note that these cost estimates are approximate and can fluctuate based on brand preferences and manufacturer.īMW E Share on Facebook. The Repair Cost graphically displays approximately how expensive the repair will be to perform. As the difficulty level rises expect the repair to demand more time, use more specialized tools, and require a better understanding of mechanics to complete the job.
Make sure to use the following torque values when tightening down the intake manifold nuts and throttle body bolts.Īnd congratulations for Doing It Yourself! The Level of Difficulty displays graphically how challenging the repair is, from beginner to expert.īeginner repairs usually require very few tools, have short repair times and are simple to complete for even the most novice of mechanics. Take your time and move slowly when reinstalling the intake manifold. Pay particular attention when mounting the intake manifold back on the engine the threaded studs can snag the rubber gaskets, pulling them out of alignment. Make sure the new rubber gaskets are properly seated in the intake manifold before reinstalling. Section 3 - Reassembly of the intake manifold Reassembling the intake manifold ids very straight forward…just follow the above steps in reverse. Section 2 - Removing and installing the manifold gaskets. Now is a great time to replace them since they will need to be removed for this repair. Identifying and marking wire harnesses and connections is very important in this repair there are a lot of them, and labeling them during disassembly makes putting the car back together extremely easier.Īs these two critical parts age, they can cause vacuum leaks and a rough idling engine. Replacing the BMW E46 intake manifold gaskets is not technically difficult, but does involve the removal of a lot of parts. Over time the manifold gaskets become hard and brittle creating vacuum leaks and allowing unmonitored air to enter the engine. The intake manifold gaskets in the E46 3 series are notably susceptible to failing in these brutal conditions. On just 18lbs of Boost we were able to add 23hp and 16ft/lbs of torque peak gains! We expect these to grow much higher as boost is increased and with the right tune.Many critical engine components, especially those that comprise the air intake system, are made out of plastic or rubber and are especially prone to failure in the extreme heat of the engine compartment. The car tested was a single turbo 6466, stock head and block. The Original Design and Prototype was tested back to back on the same car against the Factory BMW Intake Manifold.
Optional 3” Charge Pipe with Tial 50mm BOV Flange.E85 Compliant Fuel Rail Kit (Plugs into Factory Fuel Sytem).42lb injectors will support up to 750whp, 72lb injectors will support up to 900whp.Optional Port Injection including 6 Bosch Flow Tested and Match 42lb or 72lb Injectors.This was built by and for the true BMW Enthusiasts! As fabricators we knew this was an easy fix for us, but what about everyone else? After countless hours of R&D, testing, dyno time and general obsession, we decided on a design and started the ball moving forward to mass production. We wanted to address both with one solution. Two major hurdles preventing large numbers in our platform are fueling and the plastic box BMW decided to use for an intake manifold. After 2 years of waiting we are proud to present the Doc Race N54 Intake Manifold!
