During the period where the 5SFE 4cyl and the venerable 3 L V6 was an
option
in Camrys (approx '93 to 2000), both engines in particular the 4 cyl,
suffered engine failure due to excessive sludge build-up. In the US, the
greater number of buyers (Camry was the top-selling medium car) a class
action was successful in gaining extended coverage provided some form of
routine sevice could be proven.
Toyota claimed the problem was inadequate oilchanges, and in many cases
this
was true,..but not all.
I stuck to a 3000k oil/filter interval for the '95 4, in an attempt to
improve engine life but the surprising thing was despite this, carbon-like
deposits continue to form on the ledge directly under the oil-filler cap.
In
the 36,000ks and 5 years I've had it, carbon deposits have amounted to
around 1mm thick. No doubt they would have been thicker if I neglected
oil/filter changes. This unsatisfactory for a modern engine ~(8^{)
