Head Gasket or ATF cooler leak? New to m103's

visal911 · 04-19-2012, 03:58 AM

Hi all

I recently bought a m103 powered 89 300CE and i found some oil in the coolant. I'm pretty sure this is a head gasket leak but what are the tell-tale signs of a atf cooler leak inside the radiator?

The milky residue in the coolant tank cap does look kinda pinkish....

Car starts up and runs perfect.

Maybe its both?

NO service records of either service being done to the car. Shes got 230,000 KMS on her (143k).

Also which HG should i buy? Reinz or Elring?

Thanks a lot for your help.
