Hmm... first I`ll look exhaust system.
I don`t belive that it`s end of engine, because sound is not so big..

It is difficult to explain how it sounds.
When accelerating slowly to 2500 rpm everything is fine, no sound, but when push hard on gas pedal or raise more than ~2500 rpm engine is dust, not pull and starting very loud sounds.

Sounds like a fooked bottom end to me :?

In my experience a bottom end sounds like a bell donging, dongdongdongdongdongdong,
An electrical fault, plug, lead breaking down under load sounds like a loud parp PAAAAAAAAARRRRRPPPPP when you try to accelerate, hope you are able to understand what I put here.

Sounds like big ends to me. If on partial throttle there is little or no knocking up to about 2500RPM and then it gets louder with higher RPM while knocking increases it's frequency with engine RPM, then it's probably big ends. Does the knocking get a bit quieter on an engine overrun (deaccelerating in gear)?
If knocking gets louder on overrun then it might be main bearings, but I doubt that.

Or does it sound like a Subaru Impreza? Then it might be head gasket.

Hope it helps,

Only thing that puzzles me is the loss of power. If your bearings would sieze, there is just a minor power loss (until it gets really nasty).

Is your car misfiring?

Best thing would be if you could shot a video with sound. Because it's hard to diagnose anything if we ask you if it sounds like BLAAARP DINGDING DING... :lol:

Yes I understand clearly.
Sound is Parrrparrr, but nor loud when accelerating, But when you reach ~2500 rpm engine stops pull and sound is like exhoust but heard it not from back, but from engine.

Oil in your spark plug wells causing a severe misfire?

does it rev ok past 2500rpm in idle ?

kenny

Check the simple things first, things that cause a misfire under load like plugs, ht leads, oil in plug well like cliokiz said. Doesn't sound like bottom end, sounds electrical

I think the filaments collapse or sometimes the wire wool that helps reduce noise from silencers starts coming out in lumps too :)

Miaow.

Yeah, basically the honeycomb structure inside the cat collapses and if it turns sideways it blocks the channel.
