Add me to the new engine list
Well expensive weekend for me..
- car oil pressure dropped - oil temp started to rise.. - and rod started knocking.. Oil looks like graphite.. joy.. Car was 2 quarts low on oil, and I don't have a leak looking for suggestions on where the oil went.. underneath the car is clean as a whistle.. - John |
damn.. sorry to hear man.... is there oil in intake, TB etc?
If its not leaking then in theory it was eating it right?... ( or was low period during a change obviously) |
More information needed. What were you doing just prior? Recent oil change? Miles on car? Year model? Mods?
|
If not leaking oil and level was correct, then it had to have been ingesting it, rings or valve guides. Where you seeing any blue smoke on first start or while running?

Is the car an '09+ with 10.5 qt dry sump?
|
More going on here than 2 qts down in the dry sump whether 8 or 10.5 qt capacity unless the car was on a track at 6-7,000 RPM. Even 2 qts down on a 8qt Z, just driving down the road would not spin a bearing causing the rod knock. The engine would have to be close to out of oil for the low oil to fry the engine.

Bummer;
If an oil pump dies it can pull from tank but not scavenge back to tank, oil can be in sump. It will hold the entire tank. Pull sump drain plug with a clean big container. |

When's the last time you checked the oil level? 2 quarts would not be unheard of on these cars if you were toward the end of a change interval and beat on it a lot. I agree though that it doesn't seem like even 2 quarts low on your car would matter unless you had sustained g load.

this is impossible ls7's only die from dropped valves
|
Yup, sounds like you lost a pump.:( Sorry for your loss.

Well at least you're not buying a complete different long block, so it could have been a lot worse..
|
damn. So essentially you are saying the motor had 1 quart of oil in it?!
|
Still don't know what caused the rod bearing failure but it's pretty obvious it failed, luckily I just dumped the clutch and pulled over and killed the motor before it got much worse...
