This car has been in my family since early 2000 and now is been driven by my father. It always has had very small oil leak, drop or two a week, never thought much about it but from january oil leak increase sustasly, it leaked 1 liter of engine oil in less then 30 days so i decided to pull the engine and box out and do a full service and reseal the engine. Removing the engine wasn't too hard, i've grown up with those cars so 5-6 hours it was on the ground and i separated the gearbox from it, biggest disappointed was the flywheel is in much worse state than i thought, is worn 0,12-0,15mm and i can see it wasn't machined straight from the factory, i have couple more flywheels from the spare engines i have but they have 0,02-0,05 mm worn, i'm not sure is that acceptable or should i just chuck it up in my lathe and resurface it? Also the cam oil seal was replaced with the timing belt less than 50 000 km ago and it has failed and soaked the belt in oil, so new timing set as well.
