I will be the first to admit, I don't follow the strictest of oil change schedules. I've spent the last couple of years broke and barely scraping by, unable to sell my car because of several factors.. As such, I usually go longer than the 5,000km suggested intervals. (typically i go to about 15,000kms) and after 4 years of ownership and gradually getting more and more relaxed on the schedule.. this is what I found when I cracked open my valve covers to do a timing chain replacement:

Change your oil. Change it often. Change it more often if you drive your car hard.

Im so ashamed as a self proclaimed "car guy"

I was changing my oil at 12,000 km's, but since my car has 85000 km's I am going to be changing mine at 8000 km's. How many km's are on your car. Also how long were you changing your oil after being more relaxed.

I have just over 155,000kms on mine. I was Going 15,000 on each of mine. the most relaxed I got was up to 17,000kms which in hindsight is WAY too long.

Stupid. So stupid of me.

Whoa! I don't even know what to say. I see a lot of issues ahead of you. I don't even know how you can clean that without pulling the whole engine apart. Being as it's a VVT engine the sludge in there is a major issue I would say. Are you getting cam actuator/solenoid codes? If you try to clean it then what? It goes in the pan and clogs the oil pump. I would say most economical option is to abort mission, put it back together and trade it off! I don't feel that trying to clean it without pulling the motor and doing a teardown is even a realistic option with it being that bad! Keep us posted on what you do either way. And a 6 month update...

Yeah, that was my first thought.. issues i mean. I can't and won't pull it and do a complete tear down. I just don't have the budget for it. i had been getting P0008 and P0017 codes indicating timing chain but im starting to think the sensors were just dirty and giving a false reading. I'm kind of dumbfounded and completely unsure of what to do.

With that kind of kilometers that is way to much especially with dyno oil. On a low kilometer engine that might be okay. Wow I have never seen this on a G8 before. Are you sure something else was not going on.

I was lax but not THAT lax. I was sure something had to have made its way into the oil or SOMEthing. I mean i've been working on and around cars for years now and i have literally never seen this before.

Oil is pretty cheap not sure why you were going that long. The olm was not going off before that. Also there was a revised amount that the OLM should go.

I had a conversation with my dad, who has been a mechanic for some 40 years. He told me if i can't strip it and do a full clean, then just scrape it out, suck it up with an old shop vac as much as possible and continue on with the timing chain replacement. when done, put cheap oil in, run the car for 150-200kms straight to let everything heat up and work around and then immediately do another oil/filter change and put better oil in. he insists it should be fine and i shouldnt hae to worry about dropping the oil pan or the pump getting clogged. (not if i suck up the sludge)

Its quality over quantity.
Some top shelf oils can run well over 10k miles with out breaking down. Some cheap oil is broken down in the bottle.
I've seen construction equipment pass sample tests with the same oil for years.
That pic proves the convenient oil change spot used the cheapest bulk oil they could find.
Sorry about your luck and thanks for posting to show others. Maybe people will learn off your miss fortune.

I hope for your sake he's right. I'm doubtful on that theory but hey it's dad! I'm not sure how familiar he is with VVT systems but here is a decent read. http://www.underhoodservice.com/Article/101608/the_ins_and_outs_of_variable_valve_timing_vvt_systems_and_their_role_in_vehicle_emissions.aspx

Again keep us posted after the repair is completed. I'm interested to see the longevity of this engine.

hah yeah, i always go by what he says because he's typically right but honestly i am not overly sure how familiar he is with VVT systems.

with any luck, this thing will run smoothly again soon enough.
