Title: Oil leak on v6 and sludge in header
Post by: 9jdm on 18 November 2017, 16:34:59
Hi folks. I had a check engine oil warning and when I did found evidence of oil around front right side on subframe and the undertray when looking from front. I can't see any oil leaks as such. On closer inspection I noticed the  header tank has the dredded sludge in it. So I will flush out the system and replace the cooler as per the guide but I need your thoughts on the oil around the front. Could they be related or what else should I check.
Also I can here a slight noise from the power steering pump as the pulley rotates. The fluid level did run low and I topped up. Is this a sign of future failure. All thoughts very greatfully received.

Dont bother flushing, fix the Oil Cooler issue first, then Flush (Lots of it). :y

after the Cooler is fixed then look for any other leaks.  ;)

The two issues will be unrelated. Oil leak is likely to be cam covers, front crank seal or maybe a result of your leaking PAS pump.

As Migv6 says, the 2 issues are unrelated.

Fix the cooler issue ASAP though.

Good spot. I forgot about the switch.  :y

Just randomly swapping parts is normally poor practice, but if you have oil on the front of the sump or subframe, I would suggest a new switch is the first thing to try. This is because: it's one of the common causes; it takes moments to change and a new one costs a fiver. Changing it allows you to jet wash the front of the engine, eliminate the switch as a cause, and then evaluate the condition of your crank front seal. Which isn't an expensive part, but requires the removal of the cambelt and undoing the crank pulley bolt - which at 300Nm can be challenging.
