grinding noise from DC5 Type R engine????

Hi
I have an Integra DC5 Type R (manual), only recently when i turn my car on, i let the car warm up, for the first couple of minutes the engine makes a grinding sound from the engine when i accelerate normaly,the sound is very obvious in 1st, 2nd and 3rd gear. after that the car runs fine.
also the engine light tends to come on now and then, when i turn the car off and back on it goes away, iv checked all the fluids in the engine they seem to be fine. Has anyone had the same issue, please help, i cant stand driving my car with that sound

Modifications - full exhaust
- cold air intake + pod
- aftermarket extractors
- aftermarket coilovers

First things first dude, take the car to a mechanic that can plug up an ecu diagnosis tool (who knows what they're called) that can read information from the ecu. That way, it will tell you why your engine light keeps coming on. Good chance that's the reason why the engine makes noises.

It can be many things so you best start there.If its been on for a while, take to the mechanics ASAP. Who knows what kind of damage your doing the longer you leave it.

alright cool,thanks for your help, i was going to do that, but i thought its best to ask maybe its happened to someone before.

hey did you find out the problem, i am having the same thing happen to mind

Header type? It could have something to do with your lamda sensor. When did it start making the noise? Had you recently fitted any parts?

main crank shaft bearing....

car is stock .....how much did it cost to fix ?? car is in for service now

its because its a dc5 there is your problem.

Make sure you check oil levels every weekend first. Then every 2 weeks. Your car is consuming oil or losing oil through somewhere, so you will have to top up before it goes low.

why doesn't the oil light go on if its running low on oil ?? sensor problem ??

oil light only comes on when no oil left !!! too late !

Yes, the oil light turns on when the oil pressure is low. By then, it would have been too late. Checking your oil level regularly is the safe way to be sure.

Its not too late lmao dont stress buddy, its just a precaution letting you know that your low just like all the other signals (door open, boot, hehe) but with that in mind, if your engine light comes on then start getting a tad worried :)

No, the oil light is an oil pressure light. When it comes on, damage has already been done.

The engine light on the other hand covers both emissions problems and engine sensor problem. At least when the engine light is on, a part is usually dead and needs to be replaced. If the oil light is on, be prepared to do some engine work to fix it up. :(

arronng, would that be why there would be a "grinding" noise coming out from the engine though ??

bcoz i've notice that the engine has started making the noise when the oil light was on ?

how would they correlate ?

Lack of oil means low oil pressure (basically no oil being pumped to the moving parts of the engine). The oil's purpose is to lubricate the engine. That grinding sound you heard was the metal rubbing against metal which causes wear and damage.

Yup. Will do.
Cheers.

Update: Flushed old oil and changed to new.. whirring sound has been silent ever since.

But the Oil light is still showing ? :confused:

Maybe the oil pressure sensor got damaged?

I recommend buying a new sensor from Honda spares (or get a shop to order it in for you from Honda) and replacing it. If you don't know how to, get someone else to do it. The sensor threads has to be sealed using proper liquid gasket and not thread tape.

Yeh, I might do so..
Or advise the mechanics on its major service.

Thanks for the help aaronng ! Very much appreciated !
