Oil Cooler and Vacuum Pump replacement
Hi all,
I have 2011 GL350 with 129K miles (whole engine was replaced around 79k miles) and it has started leaking oil again. Took it to a local MB dealer and they diagnosed that the vacuum pump and vacuum lines to the MAF sensor are leaking. Their price is about $2000... no mention of oil cooler leaking.
I then took it to an indy shop I take my w124... then, they told me that oil cooler is leaking in addition to the vacuum pump and they would charge $2500 to for the job. (they mentioned they would replace the oil cooler as well)
I'm thinking about doing this myself and wondering if I need to replace the vacuum pump and oil cooler or can I just replace those gaskets?
Thanks in advance
