I am looking at a 98 LS400 (4.0L V8) with 62k miles. It looks very clean and is a one-owner vehicle.
As I performed an inspection of the car, everything seemed pretty much normal.
I opened the engine compartment and pulled the dipstick to check the oil level. To my surprise, I found
the oil level at the 'L' position on the stick indicating that it was perhaps several quarts low. In addition,
I saw brown-colored varnish on the dipstick which usually indicates an overheated engine, maybe even sludge.
The owner was completely clueless about all this and said that he will take the car to the dealer for an
oil change and explanation as to why the oil was low. Although he did have records of dealer visits, he did
not recall when the oil had last been changed.
Now, I liked the car and it drove nicely, BUT this oil incident is setting off alarm bells for me. I know Toyota had
some oil sludge problems with their engines a while back. Has anyone else had oil consumption/sludge with their
LS400? Should I steer clear of this car?
