Have they shown you the warped part? I haven’t had any issues again.I've had the intake pipe replaced three times and oil leaking there again. Oil on driveway so gotta sus that, mysterious coolant leak they picked-up at service.
Intake pipes 2000km, 20000km-ish and 37000kms. Now at 40xxxkms
They're full of shit. There has to be something more than the intake pipe seal or warping. I call bullshit
