The drive over test wouldn't find a faulty AG sleeve. The AOC (Haldex made unit on front of rear diff) will have enough fluid pressure to lightly apply the drive clutch and then rear wheels would turn driveshaft. With rear wheels on ramps so you can get under car, have it in Park with key off and th...

Mixing of oil and antifreeze in the crank case or cooling system would be a give away for a cracked block. How does the engine run as...

One of the R motors had an issue where the sleeves were thin but it also only cracked when teens “ I only boosted to 28 psi for a few minutes”
