Did you get the sucking jet, OSV, CCV, various vacuum tubes? The OSV connects to the hardline oil tube. There are 2 hoses that connect to it. One a small vacuum hose another a larger vacuum hose. Assuming those have never been done, those may have disintegrated. Might want to change those out as well.

I'll orders those now. Thanks :)

Wait wait wait, slow down lol. You need to methodically think about this. If you are going to do this work, you might as well do it right.

If you go into the search function, look up "M62TU Valley Pan Gasket" If you look 10 threads down is my DIY on it. On the 3rd or 4th page, there is a parts list of everything you will need and where to get it for a good price.

You can go to realoem.com to crossreference the parts and diagrams. The parts list is pretty thorough, so whatever you may need to replace, the parts list should have it in there.

Actually, here is the link to the DIY. http://www.xoutpost.com/article/BMW%...n%20Gasket.pdf

Wait, I missed the opened up injector wiring boxes?
open it up and I bet you find burnt/melted/damaged wiring

Don't get carried away buying stuff. Diagnose first ! My thoughts are an air leak somewhere. a good diagnostics man with a smoke tester will give you your answers in 20 mins and a lot cheaper than all those new parts.also get a vacuum check on the engine to see if the PCV valve has gone on the back of the inlet manifold. This will give the symptoms you have.

@ TwinTurboGTR: Thanks a million for the Step-by-step guide that is absolutely perfect. The Sucking Jet looks brand new, along with a few other hoses. None of the hoses are mushy or spongy.

@bastereo: I include pictures of the passenger side and driver side boxes. I opened up the passenger side box and it looked as though I was the the first one to open it uo since it came off of the assymbly line. None of the wires on the passenger side were burnt/damaged or melted.

The driver side one is the one that was missing the cover. Those wires look in amazing shape. I even moved them around while the X5 was running to see if that would affect the idle, it didn't.

@ Rewmer: Don't worry :) I only ordered the gaskets for the valve cover, throttle housing and intake manifolds. Regarding the smoke test, I am searching for a place that can do that for me.


In the meantime, I did some more checking today and this is what I have. It may not change the course of action but hopefully you guys can guide me on that:

- I got a can of carb cleaner and while the engine wass COLD, I started it up and sprayed generously around the intake manifold, throttle housing and injectors. There was no noticeable change in idling.

- I did pull the same misfire codes but this time i also pulled P0173 (fuel trim bank 2) & P0159 (O2 sensor circuit slow response bank 2 sensor 2)
*** I'm not sure if those were the result of spray from the carb cleaner.

_ This time I was driving the car while I did the FREEZE FRAME, and here are the results:

The picture of the driver side valve cover appears to have a small gap between it and the cover gasket. The passenger side one has no gap. I tried to tighten down the the bolt to close the gap but the bolt just turned and turned and turned but would not close the gap. I took the bolt out to inspect the threads. They looked fine.

I'm not understand the circled pictures of the hoses. I know the one is of the sucking jet, but what about the last one? Those are booster hoses. The gap between the valve cover and the gasket looks to be within normal limits, but concerns me that the bolt kept turning. It should stop eventually. If it keeps turning, something is stripped. If you are saying the bolt is fine, then the head is stripped. The block is made of aluminum. SOmeone putting a little too much torque on it will strip the threads.

I was wondering if those are the oil separator hoses I've read so much about.

Yeah those are booster hoses to the OSV, they provide the pressure within the valve.

The spinning bolt is a huge issue. You need to thread those holes.
