Alright folks, need a wee bit of help.
My local VAG specialists have just had my inlet manifold replaced on my B7 RS4, they've had it back on and all of a sudden after idling for 30 - 40 seconds they gave it a few thousand revs and a rattling noise started at the back of the engine so they turned it off. They turned it on again and the rattling started again as well.
The engine hasn't been started in 2 weeks and they did a compression test on all the cylinders to see about any valve damage and all was where it was supposed to be.
Does this sound like a timing chain tensioner on the way out to anyone else? Or does anyone have any experience on this?
Any help is appreciated and thanks in advance
