your bank 1 intake cam is fine. The valve timing is so that when at TDC the valve springs will force the cam over. If you read, which before you do much else on this engine, Besian systems detailed instructions on what to do with VANOS etc, he talks about the cam rotation. Don't do anything else here until you research and become very familiar with this process. You will f this motor up quick if you don't do it exactly right. You have been warned

Yep i have scene that. I currently have the G.A.S. timing tool set and have read through their instructions. Just thought it was weird that the cams were not aligned at TDC. But now i'm seeing that it is normal when I read through again.

I am literally on step one of these instructions.

Jab, I was using the "factory" timing tools on my X and struggled with them on a regular basis. Had been looking at the GAS set and their design just made more sense to me. I finally broke down and bought their set. Glad I did. I have only used it once so far, but that was enough to nail the timing first shot and have not had to touch it since. You will love them. Just follow directions for the whole process and you will be fine. And another tip, replace as many of the gaskets,etc that you can while in there. It is a pain in the ass to tear it all apart after for some stupid leak that a cheap gasket or o ring would have taken care of. I speak from experienceÖ...

Okay so very odd findings here. Timing guides look like they are in perfect condition. I also noticed that there is no oil seperator on the right bank behind the chain? I thought these were on all m62's. This car must have a serious oil pressure issue. It seems weird that there were absolutely no engine lights or low pressure lights on the dash.

I guess my investigation goes further. This will bug me if I never figure it out. Here are a few more pictures:

***There is a hole that is about 1" in diameter right behind where the tensioner is mounted that is completely clogged with sludge. Anyone no what this is for? Picture below. (left bank picture)***

Oil separator for the 4.6is is located at the back of the engine on the outside. The M62 car engines had the oil separator on the inside of the timing covers.

Engine looks pretty clean to me. The pre-facelift 4.4 also uses the external (rear of engine) oil separator. Guess they needed some extra space for the conversion to AWD.

Would anyone be (hopefully) still reading this particular thread?


I seem to have a similar ticking noise from my X5 4.4.


I'd really appreciate to see any responses please..

Itís been a few years since I sold my 01, but it sounds to me that you have a combination of vanos noise (whoompa whoompa) and valve noise (maybe a stuck hydraulic lifter?) - the tick tick tick.

Iíve had good look with Rislone yellow oil additive to free stuck lifters. Essentially detergent oil. Sometimes you get lucky with it.
Thereís lots written on vanos rebuild.
Not hard for an experienced mechanic, but pretty complex for a newby.

Thanks for your response. I am more interested in the 'tick tick' at this point. I have already tried Liqui Moly lifter additive without success. I will try what you suggested next. I think I will have to look at the lifters eventually..


Thanks again,


Ozzie

At one point, i pulled them all out and with some finagling, got them all free and working. Pricey enough I didnít want to buy 32 new ones. I think I used a drill chuck to hold onto the small piece (which sits in a recess) while I worked the big end loose by smacking it against a board.

Hope the rislone helps!
