Rolled car

[dnos]

Looking at buying an auction car which has been rolled. Car has a L98 with 6L80E.

When it comes to a car being rolled, obviously that's not good for the occupants, however what does it do for the engine and trans?

Will the engine and/or trans be fragged?

[offshore]

Depends haha we rolled a subaru once and drove it home lol

As long as it wasn't held with the throttle pinned while upside down the engine wouldn't care ;)

I wish my car was rolled rather than entrusting to moronic Holden service departments who put wrong pads in my HSV ensuring warped discs (at my expense), then re building my engine and leaving the sump plug at finger tight leaking all engine oil after rebuild...so yeah...a rolled car can do no more harm than trusting to the experts...

WTF are you serious???

Frustration can get like that

[HSVREDSLED]

Dead serious. A rolled car gets covered by insurance. Dud work by 'experts' you just have to cop...and you will always pay....anyway..off topic..

[dnos]

So is there any major mechanical issues from it being upside down for a period of time?

[Micks]

Not really just the intake, vac line hoses need to be checked for ingress of oil etc. As mentioned above depending on any other damage too!

Just remember that once past a certain angle, the oil pickups will suck air. So assume that both the engine and trans have run for some time with no oil pressure.

If the driver was really on the ball, they may have gotten off the gas and turned off the motor, but I highly doubt that. They may have been on the brakes, but the motor will have kept running till they thought to key off, of the fuel system dropped pressure from the car being upside down.

If I was buying the car, I'd be assuming the engine might be "serviceable" but not in excellent condition. I'd also be ready to find the motor is totally shot and take that as a worst case. If it was upside down for a while, even with the engine off the cylinders may have filled with oil. If this was not removed prior to an attempted start, there may be bent rods.

All pretty much worse case scenarios Swingy ;)

If concerned pull the plugs and have a look before dropping the coin, if you're nice they may even let you do a comp test as in reality you're buying an Engine and Trans!

Look at it on the bright side, if it runs, the aerodynamic modifications might just be enough to get a commodore to 300kmph

Isn't there an auto switching safety mechanism fitted in VE that shuts everything down once it's flipped?
I saw a rolled VE Series2 where not one airbag had deployed, so the auto shutdown (if fitted standard) prolly doesn't work either.

I betcha the owner wished it flipped back onto it's wheels let alone deploying such a mechanism!! That is if the Driver is still with us??

Every vehicle worked on by a dealer is covered by a parts and labour warranty.

Who knows for sure. It might be fine...or it might not be.
Auction= no warranty.

Would oil really pass over the rings? If it doesn't under normal oil pressure then would it really seep over when upside? I guess gravity is a pretty strong force, also depends on how long it was upside down for.

Correct: but you should always be aware of "worst case" even if it doesn't eventuate. You know the rules ;).



As for oil making it's way past the rings, of course it will. How do you think the top rings get lubricated and why do people complain about burning oil.....

Think for a minute about the rings. They have a gap to allow for fitting and thermal expansion, so there is no perfect seal. Turn the motor upside down and the oil will fill the cylinders if the valves are shut. If the valves are open, they'll fill the intake and / or exhaust.

[mjrandom]

Definitely agree with the comment about the oil getting past the rings. Depends how long it was upside down and how long it has been right side up but pull the plugs and make sure before trying to kick it in the guts.

Many years ago I bought an XC Fairmont V8 which had rolled. Transferred all the running gear to another body and it all worked fine.

I don't know what you mean by this? Another mechanic found the sump plug nearly falling off and rectified. So how does the labour warranty come into it? What was I to do? Go to dealer and waste more time off work whilst they checked a tightened sump plug? (probably would have taken half the day for that). I forwarded communication to them including a report from the mechanic and the silence since has been deafening.

I know what Mick would have done! Give the loose sump plug some help & keep :driving: till she stopped...then refer back to the last service provider for a "please explain"???

Airbags don't help in a rollover, well at least not the late model triton crew cab that rolled, deployed side and front airbags and still ended up with a fatality.

It shouldn't have been particularly hard to understand what I was saying...
If it was loose from the work they did (as you are claiming), it will be on THEIR records if they resolve it, so if any engine related issues arose you would have far more come-back. You probably also had to pay another mechanic- whereas them resolving it would be free because it is covered by the labour warranty.
I just find it rather strange that, having had an engine rebuild done, you chose to take it elsewhere (whilst the engine rebuild would be under warranty) to have an oil leak investigated. And rather than deal with the place at that time, you just send them some communication afterwards blaming them for everything.
Did you go in all guns firing in the past or something???
I can't say I'm really surprised they haven't been jumping over themselves to say "sorry" though. All they have is the word of someone else saying that SOMEONE left a sump plug loose. Could have been you doing a garage oil change from all they know...
I agree that some sort of reply communication would have been good- but none of us know what you wrote.
