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..

It’s 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.

I’ve had good look with Rislone yellow oil additive to free stuck lifters. Essentially detergent oil. Sometimes you get lucky with it.
There’s 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 didn’t 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!

Chain tensioners supposedly done. Leak down test has a 80% loss of compression in one cylinder. Haven't found a long block so I drive around with it for a year now , as had the previous ownerfor 5 years. Need to replace the sparkplug due to fouling very half year or so...but hey it gets me around..
