Hello everyone! So slowly I think that my luck grip was rather a handle in the toilet.. I finally bought an Audi last week, this time B4, 2l, Bj 93. Slowly but surely the flaws show up. Now I think biggest problem: in the cooler a thick oil film has accumulated and when starting a blue cloud blows out at the back. According to the opinion of a friend this is a sign of water somewhere in the engine where it doesn’t belong. In addition, he jerks with the constant gasge and after several hours of standing I had to find a large puddle under the engine compartment. It is a blue, watery liquid, but it is also slightly oily. ASSISTANCE!! What can this be? Is my cylinder head seal over? And where does the puddle come from?? Ask for urgent help! I am grateful for all the answers…
