Diesel Sound

[Vlad_318iS]

Hey guys,

I've searched but I feel like my problem is not as serious as replacing the whole TC group of parts.

Please help:

Car has had a diesel sound (0.5 sec in length) at start up the last year but it did not seem to be a big deal. Now it's a fifty-fifty. As in:
X. Starts with the diesel sound and goes away after a second and keeps working properly.
Y. Starts with the diesel sound but does not go away until it warms up completely (as in at least 15min). And still, I can hear the sound slightly.

3 years ago I dropped my oil pan and also checked the head. Everything seemed fine, except one bolt was loose. The timing gears looked perfect and not sharp at all.



I've ordered Slide Rail (the most upper one) but I feel like its not a critical part to my situation and that I may need a tensioner + other?

Which parts should I order before going in and opening her up?

Thank you in advance!

Try replacing #17 p/n 11311743187, should be around $40.

success!

Update

So, I went ahead and replaced the chain tensioner (#17 p/n 11311743187) and oil+filter at the same time and viola!

Sound went away and engine is quieter than ever!!

BTW, after much reading I went with Mobile 1 0W-40 "The European Formula" :p So far, feels smoother at start up and feels like the engine is more free. Maybe feels like it gained a few ponies??
