hey guys, on a cold start i get a grinding noise for 1-2 seconds max after the car first turns over.

engine is 25det

it tends not to happen when the car is warm.

2 area's i was thinking are starter motor (although why would this be diferent when warm) and oil viscosity

i use motul turbolight 10/40 as do MILLIONS of other on here...

any ideas?

Could be a worn bearing, start it cold with a mate in front or vice versa so you can try and pin point it. Lots of ancillary devices can have bearing issues (air con, power steer pump, alternator)

If you can be more specific that would help.

It will change with temp because friction coefficients are effected by temperature. Hold/Cold causes things to expand and contract etc.

yeah power steering pump is on the way out... you can hear it grind a tiny bit with a stethoscope on idle.

exhaust is bot touching anything.... i've been over that with a fine tooth comb as a previous (read NON japanese) exhaust did that and caused me all sorts of headf**ks.

see this was my idea... DGAF if its just the starter motor gettin noisy... i'd rather pay for go fast mods...

it never happened till i got remote start...

remote start (viper alarm) keeps cranking for a predesignated time, and with the pfc the time the car takes to start could be anything :D

so to use remote start (which i never do now) it grinds the shit out of it for like half a second most times

There are a few threads on this one, yes it sounds like the starter gear is not returning quickly as it should.

Odds are if you remove it it will have 10+yrs of clutch dust, road grime and oil on it that is slowing/stopping it from returning correctly.

Remove-clean-replace. Unless it's chewed the starter gear or flywheel badly you should be ok.

starter motors have a overrun clutch, If your remote start has been over cranking, the sprag clutch maybe worn/damaged, when you start normally the engine over speeds the starter motor, you release key, usually the sprag clutch slips and the gear can retract. cos your clutch is damaged it maybe holding the gear on a little more

sorry to bring up an oldish thread...but mine has started to do the exact same thing only few days ago....and only does it durin cold starts for 1 or 2 seconds after the engine has started

the noise is comin from the starter motor area so im guessin the starter gear is doin sumfin wrong

how can this be fixed? would the starter have to pulled out?

its totally the starter moter... just cant release quick enough... problem is same same now.... no worse... i'm not gonna bother about it. everything else in the car works fine :P

+1 on starter motor.

mines doin it too.

Dam 33 starters.

Mine did it a while ago, about 2 yrs to be precise.

Took it out, greased it up, was dry as a bone.

hooked it up to 12v battery, let it spin a couple of times till the noise went. Sweet as.

But its startin to do it again, might just replace it this time round.

    • Once the belt slips it can very easily cause a cascade that encourages more belt slip. Check the pulleys carefully and see if the grooves have cupped. If it has it's time to replace the pulleys. If the rubber has glazed you also need to replace it. Shouldn't be shiny. From the factory there's a lot of exposed fibers(?) on a v-belt that will go away as it's broken in but some should still remain visible without sticking out significantly like a new belt. I went through this on my dad's Camry recently. It would keep slipping even after setting the tension higher, only solution was a new belt.
    • Belt polished and/or pulley(s) glazed. Rub pulleys with sandpaper, replace belt.
    • I've also got a quick jack. I would never get under my car again without using it.  While it might be quicker to use a jack and stands, it is such a quality of life improvement that I wouldn't have it any other way now.  How much slower the quick jack is to setup will be based on your circumstances. Can you leave the jack rails on each side of the garage? Can you leave the hydraulic lines attached? etc.  If you can drive the car into the garage and simply push the jacking rail thingos under the car into place, it is super quick to setup and use. But if you have to pull the pump unit out of storage, attach the hydraulic lines, wheel out the lifting rail thingos.... yeah takes a bit of time. Having said that, I would still prefer that to using a jack and stands lol.
