Needless to say, I cleaned whatever I could in the oil filter housing and drained ALL of the nasty burnt oil from the car and replaced with OEM Oil Filter and Almost 9 Qts of Mobile 1 5w/30.
The car has 100k on it and the engine runs fine as if you could not tell it has that entire gunk built up inside of it.
My Question....
What can I do to safely remove all the build up from inside the engine components? I am planning on dumping this oil in about 2,000 miles and it's a waste since it's Mobile 1 and cost almost $70. Has anyone ever had a similar situation? If so, how did you deal with it?
Any thoughts would be appreciated!   |
You can either use an off-the-shelf internal engine cleaner from your local autoparts store, WalMart, etc or you can even use ATF...Google for the ratio as I'm not sure. Just be prepared for all the sludge to dislodge itself and possibly expose leaks that were plugged by the sludge before- valve covers, oil pan, etc.
