Hello, Peugeot Partner 2007 engine 1.6HDi 90km DV6ATED4 (without fap, without variable geometry, without dual heads) mileage on the top 220000km, pour Castrol oil 5W40 - this was poured from the news. A year ago I gave the head for renovation. Replacement valve seals, stems and milled seats. The engine did not take anything oil before repair. Since that repair I have to add about 1 liter of oil per 1000km. Injection was pulled out a month ago. The pump said that all 4 were in good condition, but the first injection from the timing was all in oil / nagaga, the remaining 3 dry and clean. I have to change the oil (I change every 10,000km) and I would like to flood it more thickly. Please advise whether it is worth it in this situation. I will add that the engine has no external oil leaks. Intake pipes, intercooler, throttle and intake slightly oily. There is also some oil pouring from pneumothorax, but not so much. greetings
