Could I please get some tips on cleaning oil sludge out of my 2001 Jetta 1.8t. ?
I just purchased a 2001 VW Jetta with 85,000 miles. The car appeared to be clean inside
and out. The seller told me his wife drove the car. Mid-grade gas was used (89 octane) &
every third tank was premium (93 octane)-I live in south Florida so there is no high altitude
(sea-level) I am adding this fact but I thought the computer would compensate and retard
the timing anyway. After I buying the car I found out the engine needed to be running for a
minute?- or is it more? After I bought the car I found out the turbo needed to cool off and
contributed to a sludge problem on an engine already prone to sludge. This is a turbo or
non-turbocharged problem according to what I read so far. I have mostly owned American
trucks and cars and have always been rear wheel drive because of the ease to work with
and I never liked having the skin peeled off the back of my hands. I've done most of my
work on Chevys that had 350-400 HP at the rear wheels and my gas milage was about 10-
22 mpg depending on how I drove. This why I bought the 1.8t. I just installed an new MAF
(OE) sensor but I wonder if there is crud on the throttle body and if I should pay to have
injectors and rail/line cleaned. A legit mechanic/friend -someone I trust who won't rip me off
told me 85k is HIGH MILAGE. Sorry for the long post/questions but this is background and
I'm a newbby. I hope some "gurus" can enlighten me and thank-you in advance.
