Before you tear it down, run an engine flush per the can instructions...Try the LiquiMoly engine flush, drain the oil/filter change, replace the oil.

Kleen-flo Engine flush

Rating 5.0

My wagon gradually stopped smoking. But it took about 2 months of adding engine detergents to the oil and gas. Finally, I did a Kleen-Flo Engine Flush then changed my oil, and so far everything works for now.

Pros: everything works for now
Vehicle: Volkswagen Passat

AMSOIL Engine flush

Rating 4.0

I've been using AMSoil 5W40 European car formula for the past 8,000 miles. I noticed a lot of sludgy nasty bits in the head last time I changed my oil. so I used the AMSoil engine flush and I filled up with the same oil and I used one of their extended life filters... I saw a lot of sludgy nasty stuff come out in the oil when I drained it... I started up my engine and it runs much smoother now and the power is much better BUT, the valvetrain seems really loud.

Pros: engine runs much smoother, better power
Cons: valvetrain seems really loud
Mileage: 12872 km
