on wednesday i got a very special car that had a problem with the automatic transmission. Draining the old gear oil looked like the car was making cooking cream. This happened because the radiator was leaking coolant and when it all mixed together it looked like cream but the smell was not very pleasant. During the rinsing, there was such a strong stench that the mentor and I could barely breathe.
to summarize the story, apparently the car wanted to make lunch for the owner because his oil looked like cooking cream.
