  1. Hi all. This is my 3rd Aurion. 2 GSV40 and now a GSV50. I do most mechanical work myself. 2 back operations have slowed that down recently but anyway on with my story. I recently purchased a 2014 prodigy. 61000kms. Started life as a fleet car and then sold privately at 8000kms to the owner before me who was an elderly gentleman. The cars in fairly good condition. His service history is not so much. Looks as if the oil was was changed at 8000, 30000 and 60000. There are 2 other services 11k and 20k but no information. So I'm thinking at worst which I knew before buying, that it's possibly gone 30k without an oil change. Now this is not 100% but is definitely possible. The old fellah had failing health and I bought the car off the dealership thst acquired it for him when he wanted one back in 2015 at 8000kms. He's apparently become ill so his family sold it back to the dealership he bought it from. Good country town ethics. Anyway so they didn't really want to call the old fellah to ask about the missing 45000 service. The dealership rang the other mechanic in the area and he had also not done it. So let's just assume it was done at 8000, 30000 and 60000. I have not pulled the valve cover off bank 2 yet but I took off the PCV valve and it looks as followed. {SEE PICTURES) I put my pinky in the plug hole too and felt around, it definitely has a sticky varbish under the valve cover, just like you can see on the head of the PCV valve. Actual valve is clear and opening and closing freely. I've never used an engine flush before, that's why I'm here asking questions. 1) Should I pull the valve cover off too properly inspect before deciding to use an engine oil flush like Nulon for example? 2) From the pic of the PCV, would you consider this amount of varnish to be worth doing an engine oil flush? 3) Anyone had any bad experiences with oil flushes afterwards, like noisy lifters or oil leaks? The car blows no smoke and runs great but within 500km of the oil change from the dealership I can see the oil starting to become dirty. Light brownish. Not black. But it shouldn't be this dirty already IMO. 4) So is varnish worth clearing or not? What do you think 😃 I love my 2gr-fe's that's why I buy these vehicles. Not for the looks of course 😲😉. So any help on a new found topic for me would be greatly appreciated. I of course will be doing regular oil changes that I now own it and I just want to give it its best life from here on in, a clean slate if that makes sense. I won't deny I do enjoy putting my foot down quite often, so I try to give my engines the best life I can with regular servicing and qaulity fuel.
