Quick question re: engine flushes
 

Hi Everyone,

I am to the point of replacing the motor in my '04 s80 2.5t due to engine sludge. (The previous owner ran it 60k miles on conventional oil, the turbo just loved that.)

Does anyone have any recommendations for an engine flush I could try? I'd like to run something through it as a last resort since I'm planning on replacing it. It seems like Auto Rx is the favorite among the threads I've found. To give a little more info that might be helpful, this engine is very, very, sludged. I replaced the turbo, and when it came off the oil lines were almost completely blocked by the sludge. The car now runs perfect, except the oil light/no oil pressure message starts flickering after awhile. I drove it from the mechanics shop who replaced the turbo to my house about 5 miles/15 minutes away, and there was no light until I was turning in the garage. It just seems so close that I'd like to try a flush in hopes that it would "fix" it, even if the engine only lasted another 6 months that would be better than having to buy an engine right now.

Thanks in advance for the recommendations.

I would try seafoam treatment through the oil. Run it 200 miles change the oil and do it again and see how it goes.

Ok cool thanks for the suggestion I appreciate it.
