ATTENTION: Nighttowl, Chigga . . . .AND EVERYONE ELSE

[Ballard540]

Nighttowl I'm at my ends with this engine and its noise. I'm in desperate need of your timing tools whenever available. ASAP preferably but i know people are in line.

Chigga I did what you talked about. And I'm not sure how by just removing the disk and screen you got a coat hanger or likes of up into the tube the feeds the engines oil supply. So i just removed the oil pump all together. Cleaned and inspected with no problems. Only thing is that the actual "screen" that is used to trap large items before entering the pump had plastic parts trapped between it and the disk piece. So It's removed now. I FEEL like i notice a difference in power. Especially bottom end. But I still have noise. MAYBE a tad less. . . not sure really /: But I'm starting to seriously think that my engine being out of time is causing additonal noise. I mean when yoiu think about it having an engine like this off time is not only dangerous because of being an interference engine. But also for the vanos. Which uses mainly two things. Oil pressure and Timing. So if the timing is off that might make the solenoids close off oil pressure to the acuater units at ideal causing the "diesel" effect. Actually i think now if i remember correct the solenoids have a neutral position too so maybe thats my conflict. It thinks the engine is running different than it really is because of the timing over advancement and trying to compensate by not applying oil pressure tot he units.

Guys idk this is all just things i can think of. I am no BMW tech by any means. And only try to make logical decisions based on what i know and learn. So if anyone has any insights feel free to post.

Hey Ballard, I'm not 100% sure either, as I've mentioned before, Olek had tried the method and it worked for him, I havn't got around to it yet so I couldn't confirm it works for me, kinda like the vanos units, it worked for one of the member, but not for me.

I guess the first question is, who did the install of the chain? was everything put back correctly? have you done emission or compression since then? if the timing is off, I personally believe it'll show on emission and/or compression reading, I had to do emission right after the job and all the readings were perfect, so I knew the timing was bang on, which sucked, cause I was looking at excuse to re-do the exhaust.

Another thing is how is the clacking sound? does it go away after certain rpm or is it present in all rpms? mine only does it at idle and goes away as soon as you get on gas.

I know this sound is extremely frustrating and embarassing, but just say its a diesel conversion and eventually we'll find out all the culprits.

[Ballard540]

The noise is terrible at idle typical diesel noise. But gets quiter then from about 2100 till about 3000 itthe noise changes to more rapid and softer tick. Then above 3 grand goes away. But at idle it is defniatly a clacking sound.

And I did all the installation of the timing components. And i didnt mean to say i replaced the chains because I didnt. I had a brain lapse ha ha

And i have not done emissions nor compression test.
I do have an engine light on though saying timing is over advence . . .

Another question while i was in there last night i noticed the oil pump change had excessive slack. Is that a normal wear part with these cars??

[nighttowl]

There is supposed to be some slack in the oil pump chain, and also the oil pump bolts are known to loosen up. i wouldnt remove the screen in the bottom of the oil pump, if it sucks up a larger piece of plastic (we know where the plastic comes from) it will destory the pump, then you'll have oil starvation. if your experiencing different results with the screen, you may be getting cavitation in the oil, which is usually caused by a number of things, like windage, too thick of oil, low oil level, oil pickup isnt low enough, etc.

i believe the tools just arrived in new jersey yesterday, so they are on the east coast. the chain isnt a maintainance item, but if it has damage from rubbing on aluminum, or what not, id replace it as its only 80 bucks.

if its a solid clacking sound, there may be something wrong with the guides. id check your oil pressure also, it should be a minimum of 7 psi at hot idle, and should correlate with about 10 psi per 1000 rpm.

im not sure if the timing being off causes additional noise or not, but i suppose its possible, maybe its cutting oil supply because it thinks its over advanced.

we have the timing tools ready to go out today, give us a call.

Will you have the tools to replace the cams on the I6...?
:D

[Mark@EAC]

Jared and I were just discussing getting a timing kit that covers all of the I6 engines, send him a PM if you are seriously interested in renting that timing kit and we will buy it.

[Ballard540]

I removed the screen because it was not possible to clean it any other way. It had SEVERal small pieces of plastic in it that i coulndt remove before when i done the job timing rails. So now i gotta find a way to replace it or something along those,lines . . .somehow.

And thats what i was thinkink nighttowl that its over advance limiting oil and causing noise.

Whats really cool man, is if you want to talk to Chigga, you can PM him

[Ballard540]

Yea? I am. This thread is here for him and anyone else who has useful info to add to the subject.

The cool part is that it's a good thread revolving around M62TU motor noises that pretty much affects E39's, E38's and X5 owners.

Go wash your car or something, people are actually trying to be informative and spread information that isn't in the FAQ.

Wow cool guy. Your really cool.

I only mentioned it because two of this threads were specifically asking for Chigga. If you have a question for him PM him

[Ballard540]

I'm really not trying to start anything. It was adressed to him because of his theory on why SOME people have this noise. And i felt what better way to share it than start a thread where some people might say you know what I think i will give this a try.

Also taking OUR otherwise private messages public for everyone to see and give pointers/ideas/experiences etc.

Really? This is a problem for you? I'm following this stuff intently. Especially after hearing that the chain guides and VANOS did not solve the noise problems for Chigga.

Feel free to use the ignore button or just skip all these threads. Better yet, maybe you should send Ballard540 a PM asking that he use PM's instead of posting threads for the general public.

guys, easy, I'm not used to all these attention, I'm blushing while reading this.

[Ballard540]

pa ha ha ha well on a better note does anyone know for a fact when the vanos works?

For example: (and example ONLY) Say the VANOS advances timing at idle (which it does) then when is the RPM range that at faults to the neutral position. Then when does the VANOS kick back in (either advancing or opposite of adavnce) lol some forums i know your not allowed to say the R word ha ha.

Because if i can figure out where the working RPM range of the VANOS is i think i could explain why my noise changes with RPM and so fourth and so on. Only in theory though. This can always differ from reality
