shit engine noises :)

[Brody]

2 problems here,

The first being since I've added in an apexi pod filter, after around 6k rpm, im getting this crappy tinny crackle type noise coming from what seems to be the drivers side. Its not consistent and not continuous. I haven't reset the ecu since adding in the filter, any ideas?

The 2nd problem, is usually after some hard driving, tapping noises come about.

Seems to be coming from the very front of the engine, and only sounds like 2 components, in sync, going 'tap tap tap tap'. If i rev it, they speed up obviously, and basically to the point where the engine drowns out the noise.

Not great detail i know, but any help would be much appreciated

yeah i've got lots of funny noises going around in my car too ... like funny tap tap noises when i'm changing from a particular gear ... but it sounds like its coming from the rear ... also i think some panels are loose ... are there any tips for reducing these things or to finding out what is causing these noises??

thanks

is that tap tap tap tap tap tap tap tap tap....?

or more like

click click click click click click click click click ....?

cuz I hear those sounds under the engine I never able to find the where it originates from... but cold morning it comes and as I rev it gets faster... very strange.:uh-huh:

cheers

Joe:rolleyes:

yeh easily its more of the tap tap, even a knocking sound would be a good description...

i havn't heard what 'knocking' and 'non detonation' issues sound like, so makes it harder still

[Brody]

2 add to this,

my clutch started slipping alot tonight,

got out, couldn't put my hands on the bonnet for more than say 2/3 seconds without it burning my hands. This was after idling for 10 min, where as touching it straight after i got out, it was fine.

Water temps are normal, as is oil pressure, everything seems normal apart from the idling getting 2 low 2 often.

Im thinking perhaps the oil pump?

[adam 32]

knocking/tapping can be either noisy lifters or an exhaust leak

although these noises normally go away when the engine warms up

[Brody]

hhmmm mine only comes after copping a hit usually...

1 other question,

after idling for say 5 minutes, the bonnet is pretty much that hot i can't touch it for more than a second, now ive never noticed that b4 at all, though is that normal?

[adam 32]

it shouldnt be that hot.... my cars black and even after a hard run during the day the bonnet is touchable.... check coolant levels or maybe flush radiator/cooling system

[Brody]

****.

Coolant levels are all good, though a mate recons the water pipe going to the radiator, should be pretty hard due to pressure. When squeezing it, the water level rises obviously, but theres very little pressure.

[Brody]

Just to update every1 following my issue ,

To deal with the heat issue, we flushed the radiator.

Now thinking the thermostat might have been rooted, we spent **** knows how long getting it out, and when testing it in hot and cold water, it didn't move the slightest bit, and even trying to force it open, was useles.

So needles to say we thought we had found the problem. Put it all back together without the thermostat, put new coolant in, 5 minutes later same problem, everything is 2 hot to touch, be it intake pipe, hoses, engine, bonnet etc. This is after 5 minutes of idleing.

Car goes to the mechanics asap

[adam 32]

yeh dont drive it too much eh. sounds kindah serious. i cant think of anything else in the cooling system which may be ***t... the radiator core? better get it checked out!

good luck with it

[Brody]

Well theres no leaks,

and i just had a gtr radiator and r33 fan put in a few months back...anyways, see how everything goes at the shops.

Thanks for your help

Brody, that "crackle type noise " could be detonation, mine used to do that at high'ish revs:( , I noticed the car was also a lot quieter around the front of the motor after I replaced my cam belt, and guides, if this helps, or may spark an idea?
