knockin noise, could it be bottom end?

[[JNS 012]]

i hab a problem with my s2000
there is a sight knockin noise when i rev to 3500 RPM...
i think the noise is coming from the bottom end.. >.<
and also when i drive the car from stop to start i can feel the car has lack of power... is it because i hab a custom exhaust??
or is it just how i drive which effects the drivin??
has neone had this problem b4..??

engine knocking is commonly caused by fuel types (correct me if i am wrong)... did u just swapped ur fuel type? say from 95 to 92? does it happen all the time?

OMG~! ur rite.. i work at a mechanic shop... atm...
and yesterday there was a car which was gonna go to the wreck
but it had a full tank of fuel..
and i took it and put it into my car..
but i filtered it twice b4 i dropped it into my car

man u might hab the answer

engine knocking? lose of power?

sounds like your engine is about to die?

When i was doing some research on the s2k before i went and got mine i was reading up that the guys in the US had many problems with their motors seizing. Most had the symptoms that you descirbe, engine knocking and lose of power....best to get it checked out. but i could be wrong

[jamchen]

but before putting anything serious... maybe try to drain out what's left in the tank (if there's not much left), or you can fill up the tank maybe with ultimate or else which has higher RON grade.. see if that minimises the problem.. which i think it should.
s2000 has quite high compression ratio so its always a good idea to always fill up with at least 95...

sounds like you targeted the problem.
can also be a timing problem, but if you recently filled with incorrect fuel..

if .::F[L]Y::. is right.. then im DOOMED>.< man
3 months ago
i had my s2000 written off.. and if my engine dies on me
man s2000 is not the car for me....
better off stickin to my previous car GTR skyline

[.::F[L]Y::.]

im just saying that could be the worse case scenario. The only time i heard of it happening was to some guy in QLD.

Think it was just bad fuel. my advice is not to rev past 4k rpm until u drain it out completely.

[[JNS 012]]

yer great idea..
nono even better .. tmw ill just drain the sucker out and at the same tym il change my fuel filter
just dont wanna risk the chance

'] change my fuel filter



lol, do you know what that involves.

the fuel filter is massive, the biggest fuel filter ive ever seen in my life lol, and probably the most expensive ive ever come across!

pretty easy job if you know what your doing.

1. leave roof on
2. undo the plastic bits under the rear window section
3. open your fuel cap (where u pour petrol) to release the pressure etc
3. undo the thousand bolts they have bolted down on the fuel tank lid
4. use pliers to undo the tubings on top of the fuel tank
5. lift up the lid, everything else will come out with it

6. replace the filter and reverse the procedure :D

7. check all pipes/tubes
8. start car to check for leaks or anything thats squirting etc..

if none, your all set to go, and finished.

[N1RAY]

I think your jumping to conclusions.

Change your fuel filter if you think its nessecary, i wouldn't be puttin fuel from unknown sources in my S anyway.

"A knocking noise" could be anything.
Is it mechanical knock? engine knock/det would hardly be audible at 3000rpm

if the fuel batch is extremely bad it could knock at any rpm (the cheap koala brand petrol stations for instance lol)

I think that pretty much sums it up.
