Not like marbles in a can at all - just a faint ticking.BGKBCK said:Does it sound like marbles in a can? If so, then that's detonation which could be caused by excessive heat, bad gas, lean conditions etc...If it sounds like ticking it could be your headers or possibly or an exhaust leak? :cheers:
Not at idle or when out of gear - from 3k up or when the other noise (wind engine) overwhelms this faint ticking.BmwNut said:Might be an old lifter, but those you will usually hear at idle too, out of gear. Does it tick in every gear? Is it just at 3k and then go away or is there a range of rpms it ticks at?
Mike - yes, every gear - not in neutral, no load and no noise under around 3Kmottati said:i'm still a little unclear. Is it in every gear, in neutral, no load. no noise below 3k? Can you hear it in the car, with the car/windows closed up?
Might be worth checking the plugs, a loose spark plug will cause some noise like this.
UB,Úbermensch said:any update on this tranck or did the problem just go away ?
I'm experiencing the exact same thing for the past couple weeks, a timing related ticking\clicking noise from the engine under load irregardless of rpm, ie. 1500rpm 'tick tick tick' under half load to rapid succession 'tick,tick,tick' under full load right throughout the rev range (at first I thought it may have been valves hitting pistons h. I replaced both vanos solenoids which alleviated the notorious startup rattle but figure this is either a timing chain tensioner or hydraulic lifters ie. something mechanical as the diagnostic reader doesn't return a fault code and the car runs reasonable well otherwise with lots of power and has new maf's cps etc.
I presume its going to be difficult to pinpoint a cylinder with stethoscopes etc. as the car sounds almost perfect when stationary and being revved in the garage, the problem only emerging while the engine comes under load, so would a stuck 'lifter' be immediately obvious once the rocker covers been removed?
It's a VERY loud noise (almost like someone tapping the engine block with a hammer :confused2) on cly. 1-4.
Any ideas ?
This car's oil level has never been below a quarter of a litre low and I aways used the recommended 10W-60.Úbermensch said:hooooly sheeeet that sucks, sorry to hear that man, I better do a compression test pronto, did you run low on oil or something ?
It's a nice car but I think i'd throw a match to it and claim the insurance rather than cough up for what's basically a new engine
