Hey guys like the title states , I have a very weird noise in my engine bay , and it increases the more I push the throttle down. Its really worrying me as I hope its not the bottom end. Mods are just dual cone intakes and Jb4. Any help would be greatly appreciated.

My car makes the same noise from time to time. Does it do this all the time? I have heard others talk about this and seems pretty common. I'm sure if you do a search you can find something that talks about the noise your describing.

Sounds too high pitched to be anything on the bottom end. Sounds more like an intake valve or a lifter. Did it start suddenly or build up gradually over time?

What happens is the oil 'burns' on a hot spot, and little tiny flakes come off over time, and get stuck in the valve lifters, making this noise.
It sounds like a single lifter to me. On my old V8 a 50/50 mix of Redline 5W30 and M1 0W40 was able to clean most of it out over the course of about 15000 miles... |

Truthfully speaking it does run normal, because I have to drive it everyday. It's just that noise is annoying. \

Either way - if the sound wasn't there before and now it is - you should check it out, waiting will accomplish nothing. |

damn! for some reason I thought the noise was coming from the rear left corner of the engine bay (exhaust valve lifter problem is very common).
Did they determine the cause of the pump failure? I ask because I am in the process of replacing my PS fluid.. the stuff in there looks like the alien black oil from the x-files... |
