I decided to give Kreen a try.. The following pictures show what I will describe.
I recently purchased my car, and after changing the oil I found that the original filter had been in so long that it was falling apart, and literally was filled with chunks of sludge!
I also had leaky valve cover gaskets, so I decided to change them. And to my horror, I found TONS of sludge build up.. (see pics) So I had the covers sand blasted, and replaced them. Then Ordered Kreen.
After dosing with kreen, I ran it 250 miles and the oil turned black so fast that I immediately changed it again. (pic or two paper towels)
Now, I am going to dose the car again and run 500 miles, followed by a third dose and 1k mile change. Also, from this point on the car will only get Lubromoly 5w30 synthetic.
Thats the story so far, and I will update with more pictures when the treatment is complete..
Enjoy the pictures
