Hello :sad1:
Now it has happened.... Last thursday after changing to summer tires, I started the car and it sounded like a concrete mixer.... Obviously I didn`t drive the car after that.
Took it to a BMW specialist and obviously the timing chain tensioner has quit its day job.... totally slack chain.
The cam prockets were quite worn also.
Now I`m just waiting for the final judgement: Is the engine history , i.e have the valves had a hot date with pistons lovelove

The worst part is that I planned to change the tensioner at next service.....

Well well...
:crying2: :crying2:

Hi!!
The valves have not made contact with the pistons. Im having the whole timing chain, tensioner etc. replaced, I think I`ll have the top owerhauled also while I`m at it....

The tensioner had stuck and was compressed when they pulled it out.

Hello Sakke
Please consider the wear on the chain sprockets. They should be changed if the chain is replaced. New chain & old worn sprockets is not good.

Think I need to look into changing my tensioner also, starting to get a little noisy,Is it a big job? Is there a recommended mileage? my car just turned 90 000 miles,'90 model.

Hi!!
Not a big job, An experienced BMW mechanic does it in half an hour, I`m told. Tensioner costs ~70£.
Do it.
There isn`t a specified mileage for the change of the tensioner, Noisiness is one reason to do it.

:cheers:

What kind of noise does a worn tensioner make?
Hi!!
Well, the tensioner itself doesn`t make any sound, but it is the timing chain that starts to rattle, especially at startup from cold. Rattling noise from the front end off the engine/"noisy engine"

Can`t describe it any better, somebody else give a try?

Please read This Article about the installation of the S50B32 tensioner in the S38 engine.
Very Good Article Raymond.
Excellent technical content & well written.

I did not know this article existed but had received other information about 2 yrs ago on the tensioner used on the E36 M3 EVO. I had already replaced the std tensioner a couple of years before this. I have the Evo M3 Tensioner fitted to mine just a few weeks ago as an oil leak using the std tensioner had developed.

Hi all!
Well, I have received the first price estimate for the work and parts..
Parts (Timing chain, guides,tensioner,sprockets, top gasket, top bolts etc ) 12500NOK= appr. 1500eur
Two days labour 10000NOK =1200eur
Plus the price for the labour for overhauling the top ~1000 eur

Total cost est. 30000-32000NOK = 3500+ eur :sad2: :eek: :mad:

I`ve got the downpayment blues.......
