I could not see problems until assembly was removed. I am systematically taking them all out and ohming them out and putting them back. Figure 2 Be prepared to catch leaking fuel when the fuel lines are disconnected. May 7, 2015 Followup from the Pelican Staff: 11-15-7-522-931-M9 Search this number on pelicanparts. Today morning when I tried to start it it was idling rough especially in park or neutral. In advance thanks for the help! This is a screenshot view, this is a view actually of the intake manifold with the engine removed. It is on the passenger side, and was attached to the black cover for the whit electrical junction box.
I agree, if you're not comfortable dropping engine, don't pull intakes and alternator. I can't find the fasteners nut set could you please guide me where to find them?. I really had hard time with the other hose that is under the intake manifold 4 in picture attached. I'm just curious, when you guys do head gaskets on the m103s, do you guys always remove the intake manifold from the car? Manifol is broken loose and is still held back by someting I can't see. Is the check engine light on? This manifold is often used for 325i, 328i, 528i and other cars with the N52 engine to boost top end horsepower.
When all of the top bolts are off, it will jiggle back and forth but not come up. I would check spark, fuel and compression on all cylinders. The torque screws that hold the wiring harness bracket to the intake will strip out assuming you find them and you have to get creative to remove that bracket! Vehicle models change and evolve as they grow older, so the vehicle shown in our illustrations may vary slightly from yours. Removing the shroud has to be done after the manifold is removed. The only thing it cannot be is moderately important. Sometimes the valve cover gasket can leak into the spark plug hole and soak the electrode.
July 9, 2015 Followup from the Pelican Staff: Thanks for the additional info and feedback. It is still running rough on idle. Wire length is specific to connector location and could put unwanted stress on the harness. I looked underneath and seem to be seeing this hex head bold holding it on still. I may be able to figure it out then.
One thing I did do is take the new gaskets and use them as a template to cut out some masonite port blockouts. To get the sound you want, you lengthen or shorten the horn to achieve a resonance tone. And I did get a wonderful used engine from that move, an 89 built M103 instead of the 86. Broke down and took it to my local shop. September 25, 2015 Followup from the Pelican Staff: Could be a vacuum leak, aerosol spray can start a fire and will not identify a vacuum leak.
One thing I did do is take the new gaskets and use them as a template to cut out some masonite port blockouts. Not only is it easier to leave it in place, but there are several connectors on the intake manifold that get brittle with age and miles. The front one is visable and easy to remove. Does it matter for them? So in this case, it was a matter of dismantling before we could find the leaks. What did you remove first. In this section you will find the gaskets that seal the intake manifold to the cylinder head. Reach behind the intake manifold.
I sprayed the manifold with aerosol lubricant, and no idle change. Can you send my info to usmc2015 assuming he entered in an email and you have access to it? You can test the diaphragm that actuates the valve by putting vacuum on it. I still have the block for that M103 and if you want it it is free, but you have to come and pick it up. You have great access to it, and you can easily connect the hoses. I would start by checking the vehicle for fault codes.
I know I can do that lol. The wire is located in the wiring harness directly under the throttle body and it roughly 12 inches in length so I assume it has to go somewhere relatively close. That way I could clean off the top of the engine without any junk going down the ports. Thanks June 20, 2014 Followup from the Pelican Staff: If you suspect something fell into the engine. Have the shop check their work and confirm the starter is receiving the signal to crank the engine. And in that context John Hef told me, that a much better solution would be to replace the engine, not much more work, and probably a more successful outcome.
When you unplug the valve, the airflow will simply push it open and the rattling will go away. If multiple systems are not working properly, fault codes will be set. Was the added rom worth the trouble of removal? For awhile this was just a given, but at some point car manufacturers started adding in variable runner length manifolds, so that the extra power lump can occur at two separate stages. Follow the fuel line behind the intake manifold, near the firewall. I would check spark, fuel and compression on all cylinders. I like to use a small flathead screwdriver.
Plugs replace less than 20 miles fuel pump and filter replaced and fuel pressure is good. Removed block and got bolt off. Not sure I'm brave enough for an engine drop. Also I did not have any intake manifold gaskets on hand but did notice a small leak. And I did get a wonderful used engine from that move, an 89 built M103 instead of the 86. Could someone please help me! From what I've read here installation is much easier this way.
