@whitefinish, yeah i really need to get a stethoscope. @wagZE,' Yeah thats still possible, only i replaced all of that. Last year it knocked more badly. I replaced: HLA Timing belt + idlers/tensioner Alternator PS assembly Clutch, Flywheel, bearings Retorqued everything. Everything was surprisingly ...

It less loud indeed. But the fans where on to this time, so the noise wasn't recorded so well. I'm swapping out the ECU for a chipped one. So should be less rich, also it sounded like i had a vacuum leak. It's also somewhat shaky on idle. But my own guess is the friction gear. Put a screwdriver to m...

well for me its not a HLA for sure, swapped those out already. It's an inconsistent noise, as far as i know rod knock makes that "tack tack tack" noise. I cant find any reference for the Friction gear problem. Also don't know what pre-ignition sound like. Here's a video from this year: htt...

Ok were back :evil: In december 2011 i took out the engine, replaced hla's, tensioner/timingbelt. (which was broken, the bolt hole off the tensioner literally broke off). Thinking well that has to be the problem. Start her up all good, drove it arround for 10 months. And suddenly this month, same fr...

So i guess this would be an example of a bad outer tie rod end?

time and tools is not an issue.

Only the timing belt, getting the right tightness and such. Never done a timing belt.

Actually only did, the basic stuff like brakes, shocks but no real engine stuff.

yeah 10w40 is too thick, thats one reason why i changed it. Possibly to late :( To replace the HLA's u need to remove the cams right, and the timing belt for that. Something i can't do myself. Also crap that's its on the back side, then i've have to remove the intake too. couldn't see any shaving in...

Well i've just driving a while on the highway today, the knock dissapears after 10-15 minuters highway. parked the car for 6 hours started again no knock. But after a few days of driving short distances it comes back, at least that was the case with the 10W40 Oil. So i'm guessing it will be no diffe...

yeah i will check that good idea.

i'm running on "standard" kl31 ecu, they always run rich this way i heard.

It does NOT stop by 3000rpm like i thought earlier.

here's a plug, looks ok i think.

Can't get seafoam here, know about that stuff. Tried to get it for my k8. But youre talking about carbon knock i guess, would be strange this thing was clean as hell. One of the best running ZE's, according to the importer of the blocks. Also the guy who build the engine in said it runs great, which...

thats some hardcore stuff, i would never think of things like that lol so what would i do about that stuff? And here's a scenario of the whole thing: Jan 2011: bought a ZE, heard it running, super quiet. Jan 2011: ZE build in my car, swapper filled it with 10W40 Feb 2011: No Problems March 2011: Tic...

ok, something i forgot to mention about the knock, it seems to stop at 3000rpm +, or at least unhearable over the other engine sounds.

Yeah, its the loudest at the back. Guess middle cylinder on the backside. thought about TBT too, but its hard to pinpoint. Its quite loud. what if i'm not lucky? Rod Knock? that would suck only got this engine for 5 months, never run on low oil, dont burn any oil. and also no coolant i think never h...
