Hi all
I'm looking at buying an FJ Cruiser with the V6 1GR engine.
The vehicle I'm looking at skipped a service 4 years ago, and so did 20,000km without an oil change.
It's since had 3 services on schedule.
I'm concerned about permanent engine damage caused by sludge due to the missed oil change.
If I get an inspection done by a mobile mechanic, will they be able to identify whether there's any long term damage? Or, is it not possible to tell without tearing down the engine?
Thanks for any input
