While driving today I had the red oil can of doom light up on the dash. We have just changed the oil and filter and there were signs of sludge When it happened I dipped the clutch and pulled over right away and then limped 1 mile home with out the light on. After the oil change I also replaced the dipstick top section as the old one was falling apart. I fear some of the plastic may of dropped down the dip stick hole as it fell apart on Removal how bad would it be if this was the cause? Im guessing it's a sump off job with new pick up and oil pump?
