Narrative:

Took off from san juan runway 8, turned left 350 degrees, started to smell foul air and noticed left engine oil temperature climbing rapidly and oil pressure going down but oil quantity read full (21 quarts). Smoke appeared and we donned oxygen masks to 100% and put eye goggles at the ready. Did not put on because we were answering radio calls, talking to flight attendants, analyzing problems and looking for the checklist, etc. Told ATC we were coming back to airport and to have all emergency equipment out by the runway. This was what I perceived as an emergency but did not say 'declare one,' although I believed the captain did a few seconds later. ATC handled us like an emergency aircraft. Did not declare one because I never thought of it because the workload was very intense at the time. Total airtime was 15 mins. Landed with left engine at idle. It was the fuel oil cooler. Fuel was leaking into the oil which diluted the oil. The oil was then escaping past seals into air ducts.
