The mess under the intake

[Jorgeconrico]

Sorry for the multiple posts, but the first time I did this I only removed the upper intake. To remove the lower intake im assuming that I need to take the fuel rail off? I also want to replace the two small pieces of fuel hose. Will i need to depressurize the fuel system to take off the lower manifold, or can I leave the rail/injectors on the lower intake manifold? I really just want to get enough access to clean the lower manifold and replace the plastic coolant pipe. Thanks

Also I already drained the coolant because of the leak. If I do need to depressurize the fuel system I was planning on pulling the fuse and letting it die out. This may seem stupid but do I need to add water/coolant for the short amount time the car will be running to depressurize the fuel system?

I'd leave the injectors & rail on the manifold.  Definitely depressurize the fuel system...and I'd replace those PITA hose clamps with real FI clamps & all the gaskets too.  I'd also avoid silicone in the system if possible.  It's so convenient but I'd worry about it plugging up the radiator.

Dave you answered my first question, but what about the stupid second question about adding some water/coolant. Thanks Dave

[DesktopDave]

Nah, only if you're running the car for more than five minutes.  That should be well before the engine overheats.  I'd guess it'll warp the head running for 20-30 minutes with no coolant.

Top fuel dragsters have their coolant passages filled with a special concrete...if they can get away with a 1/4 miles you'll have no trouble.

Thanks Dave. I managed to pick up the OEM coolant pipe and o ring from the dealer and the price wasnt too bad at 30 bucks. I'm still trying to figure out the best way to plug the coolant pipe and the block. Hopefully the weather/temp cooperate this weekend because I'm trying to get this done before it gets real cold.

Does anyone know what the piece/hose is that connects to the lower intake? Its rock solid and I had a bitch of a time getting it off. I think it connects to the brake booster(the big black round thingy). I may have damaged the end from ripping off the damn clamp. I couldn't find it on real oem. Should I just put a dab of silicon and a new hose clamp on? Only the end is damaged and I don't think its ripped all the way through. Just wondering what the hell it does. Thanks

Edit: I looked on pelican parts and they explained it. Guess it uses the vacuum to help with the master cylinder.

do you mind sharing where you purchased on your parts?  i've having trouble collecting the 5/8" coolant hose and the high temp hose.  i went to advacne and all they had was the fuel hose.

didn't see this until now. I just went to my local autoparts store (Knect's I think it was).  I used "high temp heater hose" for all of it. It's very thick and rigid.

Just FYI, this is a great "while you're in there" opportunity to replace your injectors or at least get new O-Rings.

Here are some pics under my intake, notice how clean intake ports are, how dirty the injectors, and the lower ICV hose.  There were many more vac leaks.  My car ran well but I just figured this needed to be done with 193000.  I am adding new injectors and painting the upper intake with black crinkle.  I have already painted the valve cover.

i recently took of my intake manifold to replace my starter, i had to remove this mess of wires (it looked like a octopus of female and male plug ins) i was wondering if you had any idea how to get a picture diagram on how and what wires go where,
if not thanks anyways, pictures were very informative,  its a 318is 92, if that helps
what kinda engine do you have in yours?

Where are you all getting the 19/32" vacuum hose?  I went to Advance, Autozone, and Carquest and no one had even seen 19/32" before.  Is there a different size I can use instead?

I just brought a piece of each hose i needed and found the closest size I could. They were pretty nice, they let me sift through all of the bulk hoses they had in the back.

I was looking through this thread at some of the ways people were trying to make some sort of a filter or catch cup for the crankcase vent hose.  I'm just curious.... would it be possible to rig up an M54 crankcase vent valve to do the job?  (I guess officially its called a pressure regulating valve)  At the dealership we call it a crankcase vent valve.

If you connected the valve cover connection to the intake on the vent valve.... connected the air output of the vent valve to your throttle body, and put the oil drain hose in a small container... wouldn't that basically remove the oil from your crankcase vapors and help maintain a cleaner intake system?  Someone please correct me if I'm not understanding this crankcase venting system properly.

Only thing I'm not too sure on is the vacuum connection on the valve.  Earlier cars have a vacuum line connected, later cars have it capped off.  I'm not sure exactly what it controls inside the valve.
