Whenever I take off slowly, I hear knocking noise which I’m hoping is coming from the valve train dealer finds no issue but I disagree anyone out there use any kind of special oil maybe some thicker oil or anyone else experience the issue???

is there any way you can get a video of what you are talking about. These motors are a bit chatty and even the injectors make alot of noise too.

Yep! I have owned a number of Turbo car from EVOs to Audi S3 & S4 that all made interesting "OMG I broke it" sounds and still, this old girl is by far the most interesting LOL.

I apologize for the lack of communication since 1st post. However i am very grateful for the responses. I finally have a free day tomorrow (Friday 14 February) and will totally post an audio clip…. the noise is getting worse unless I’m just over thinking the whole thing which is also a possibility Haha. I can’t wait to see what you guys think. I appreciate all of you and thanking you in advance.

take two different videos, one on a cold start and one after you have put some miles on it. make sure you label them so we can tell them apart.

Okay finally got some time to get things together. although you don’t really hear anything at cold start up or under zero load it’s more or less under low RPM first video is obviously a cold start up from overnight and then the next audio clips will be after I drove it for a bit and I’m hoping you’ll be able to hear what I hear at low RPM besides the ticking which I considered normal, however, in the cabinet of the vehicle sounds horrible, thanking everybody for the input Let me know what you guys think.
