Intermix cleaning?

[twsarch]

Greetings. I am still shopping for a car I can afford. I am going to look at one that supposedly has a bad intercooler and has intermixed (yea, I know it could be something else much worse, cracked head, slipped sleeve etc.). I always assume an engine rebuild is in order after such an event but I figure it couldn’t hurt to ask what people think about cleaning out the engine and ways to do it, may consider even if it’s a cracked head. Same for the coolant circuit. Thanks

here in uk there r heavy duty flushes [mostly used on truks]but a very good cheat is to run engine with laundry fluid for a few hrs flush and repeat a few times it dosent harm the alloy and dosent foam up but realy flushes oil out .not so long ago bought a lateish vw passat that had had a heat exchanger replaced by dealer that tryed to flush system but still showed oil in water so condemed engine i know how hard thay r to flush so took chance 3 days later all sorted 4 bottels of luandry fluid sold car on with £2800 profit so u might be lucky cheers dave

Problem with cleaning up an intermix is that each one is different, so they are typically quoted on a “time and materials” basis; it could be a couple hundred dollars, or a lot more depending upon how long the car was run in that condition, which makes the clean up much more difficult, plus time and materials consuming………..
