R32 Gtr Long Time Idle Screwup

[Betz]

Last night I popped out to Quix at about 10:30pm and when I got home and put my car in the garage I forgot to turn off the ignition and my car was idling in my garage until 6:30am

Usually I just turn ignition off and my turb timer shuts her down after 30secs-1min, but not last night...

It got hot but didnt boil (was pining this morning and running rough)

the garage was locked up so it was sucking down some nasty fumes all night, the entire car was hot aswel, ie the transmission tunnel etc.

so, anyone know if this is a realy bad no no and am I likely to have major problems.

she also drank about $30-$40 of fuel

cheers for any advise on this one

[insanity]

thats sorta pretty funny... only cos I've amost done it myself....

don't think it can really do to much to your car.... but I'm not a mechanic.

probably just hurt your pocket with the lost fuel more than anything.

hope all goes well.

Why leave it running. Its simply not needed.

Unless you drive flat stick for the last 1km to your house simply turn the car off just before you get out of the car, if you are in the habit of tearing down your street let it idle for 30secs and turn it off. 30secs is usually the time it takes for you to grab your wallet and take your setbelt off anyway.

The turbo's are now watercooled so thermosyphoning continues to cool the turbo when you shut the car down.

I've done this for the last 5.5years and travelled over 175,000km's and never had a turbo failure. Upon inspection of the turbo oil lines and turbo its self there is no oil coking. Use a good grp iv synthetic oil and you are less likely to have issues with oil coking.

I'd simply give it an oil and filter change. Prolonged idling isn't good for the oil or bores due to fuel dilution. Inspect the plugs they may be fouled from prolonged idling.

Hmm not too good man, like CUBES said, no need for leaving the car idling for longer then 30secs, ive never had a problem either with ballbearing turbos, id be doing an oil change, being hot for 8 hours isnt too good, what do you mean it was pinging on idle?? :S

[Betz]

due for service and dyno now, but clutch is being fitted so I have to bed that in for 300k's before I put it on the rollers, so I spose I can wait another week or 2 before doing oil and filters?

and yeah I know turbo timers are overated but I have it set to 30 seconds only and as my garage is locked up at night I usually leave my keys in ignition, hence my screwup

the car was hot and pinging under light acceleration on mny way out the driveway, a bit of low speed crusing and temps dropped back to normal (my car seems to run quite hot on idle or in traffic at the best of times)

cheers, for the piece of mind tho guys, I was a little concerned that there would be potential issues with overcooking sensors and turbo oil seals etc...

[FOOLBOOST]

Yes pinging on cruse would have been because the engine was hot, do an oil and filter change as soon as you can and check your coolant level too.

dude, don't make a habit of leaving your keys in the ignition. even if your garage is locked it's a bad idea.

[arbess]

do what those guys said above i suppose. also i was thinking of resetting your computer so that it learns from preschool how you drive and the environment it is in. it would of been sucking in all that low oxygenated air causing many many things as well, hence maybe your reason for pinging....

I have heard mentioned before that prolonged idling can glaze the bores.. an engine builder or mechanic care to comment?

[SiR_RB]

yep thats what ive herd aswell. personally im not a fan of idling, even when the car is cold in the mornings, just start it, get comfy, find a good radio station and go, usualy just keep it under 3000rpms until it gets to operating temp.

but you only left it on over night once, not like you do it every week, i wouldnt worry about it too much, maybe check/clean ur plugs...

[Duncan]

meh leaving it running won't have hurt anything except your wallet. if you have missfire or pinging issues they are caused by something else.

Prolonged idling will only glaze the bores if it hasn't been run in and or the mixtures are rich. BTW resetting the ECU will do absolutely f**k all. You may have a few carbon build ups within the chambers that is causing hot spots and leading to detonation. Put it this way the more it pings the less carbon there will be in the chamber but your bearing will get a hammering. Just give it a long light load drive and see if it comes up ok.
