I changed the front valve cover on the Kluger (2005 Toyota Highlander).
Found this nice surprise. I have always changed oil every 7,000kms since getting the car at 160,000kms. It now has 220,000kms. No issues apart from a fouled front spark plug due to spark plug tube seals leaking.
I noticed that the previous owners had a mysterious section in the service history missing at around 100k, where they put over 30,000 kms on the engine with no service records.
Looks to me like they just didn't service it. Would conventional/semi syn oil for almost two years and 30,0000kms cause this?
I put some engine flush in after cleaning as much crud off as I could. Dumped oil after the flush. Hasn't blown up yet.
