Hey guys

I've got a series 2 NA R33 and there is an odd rattle in the engine.

It only happens when the engine is warmed up, and only happens when the engine is under load i.e it doesn't happen when I'm in neutral or clutch is in. The harder i push the accelerator the louder it gets, it kinda sounds like someone is shaking a small spray can under the hood, really loud though.

Ive done some looking on the forums and its not the lifters, but it may be ticking injectors. Ive also had people say it might be some loose exhaust shielding or loose manifold but i don't particularly trust them. A mechanic said it would be fixed with a new catback but i reckon he doesn't know what he's on about either, but then again, what do i know :(

Just wondering if anybody has any ideas or has encountered this problem before.

cheers

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
