I haven't been on here like forever. I have done a few things.
But anyway.
My car starts to idle like sh*t, its ok, and then sometimes its like it is running a carb and the jet sizes are too big and the float levels are out or some ancient crap like that. You start it...it runs, it coughs splutters and dies.
Mmm, where to start, so I assume everything is kinda o.k since I have replaced a whole lot of things on this and not done thousands of miles since, so I assume, plugs, blah blah are next to new, coils can die, and sensors do ruddy die, I have a feeling its the coolant temp sensor near the temp guage sensor...but even then it runs so rough and dies I dont think that sit. When I did the engine conversion, I replaced lots of things...but not everything, and one of those...do it while its out jobbies was the PCV. SO I had a feeling it was this. I did the research and low and behold the symptoms all matched, so I dug some more. Apparently some manifolds, the later ones came with an internal tube that put the blow-by gasses towards the throttle body and not just dump them above the last two cylinders. I wanted to do that! So I bought the PCV for the later model and the internal pipe and a few other things.
I tried to take the PCV and the throttle body off without burring...and of course, I burred them, most of them and it was ass, so the whole manifold had to come off.
I cut half of them off the PCV. I went to Mitre 10 and got some M6x25mm, with small washers to equal the 22.5mm of the BMW ones. My manifold DID NOT have the proper fixings for the internal pipe. I saw one bloke on the internet do a rough job of it, so...I did as well, well looks better than his anyway I think. They say because of the up-rated design that the M62b44's idle better...maybe, mine certainly runs better than it ever has, so they could be right?
Put it all together and it purrs like a kitten and the idle is now perfect, its a tad lower and noticable, mine always idled around 850 odd. Now its 700 odd and more settled, and I think revs quicker... I also replaced my coolant temp sensor with another secondhand one, cause I still think mine was...not to spec.
It goes well now, actually it goes better than ever.
So the M62 PCV mod..or whatever I think is a good way to go, even if your manifold does not have the proper brackets to afix the internal tube.
First image. So this is how it sits looking from the front. notice I havent forced it into the corner just yet.
Second image: Looking at it from the back. Can you see the two-pack araldite to keep it there, so it fits in, but it is not supposed to fit in like this actually, you need to have a look at a proper M62 to know.
Third image: I have put the tube where it should go...well if it had the proper bracket thingy. so it has some pressure against this corner, and I have removed the o-ring and again used two pack araldite.
Fourth image: Here you can see the M6 bolts, much better, its not like you are putting 300nm of torque through there??? Also see the extra outlet for...who knows, but I dont need it, so I ended up blocking it off. I am guessing M62's use vacuum for something else as well?
So I cleaned the throttle-body and lots of other details and I am rapt!!! I re-tensioned the throttle cable and now my initial throttle sensitivity is 'softer' which means its much easier/nicer to drive.
Now next is those bloody widened flares!!!
