#OilLeaks

Hey Sajeev,

I’m trying to help my aunt out with her Mercury Sable, which has a 3.0-liter Duratec engine. It has an oil leak from the front passenger side which I believe is coming from the timing chain cover. How hard is this repair and what else should I look for if, say, the leak is not the cover or oil pan? I have checked the valve covers, oil press sender, and cam sensors — all dry.

Dodge is recalling Charger and Challenger Hellcats due to faulty engine oil cooler lines which may result in a rapid, catastrophic loss of fluids. The National Highway Traffic Safety Administration filed a recall request earlier this month, saying 1,207 vehicles assembled between February and May of 2017 may be affected.

According to the recall information, the issue stems from rubber used in the oil cooler line. Chrysler’s testing revealed that the rubber doesn’t meet the company’s usual criteria. Substandard materials can allow the hose to separate from a crimped aluminum portion of the line, letting oil gush out as if someone unscrewed a drain plug.

Toyota of North America is recalling 228,000 Tacoma midsize pickups from the 2016 and 2017 model years. The affected vehicles may be leaking oil from their rear differentials. If left unchecked, the affected component could eventually seize — opening the driver up to a sudden flurry of new problems, like losing control of the vehicle moments before a horrific crash.

However, these leaks seem to cause only a gradual depletion of lubricant, giving owners plenty of time to enjoy some unpleasant warning noises as their truck’s differential slowly destroys itself.

While public complaints on the issue haven’t been overwhelming, checking in with enthusiast forum TacomaWorld led to a posting where owners reported an unpleasant howling noise coming from the rear of third-generation trucks. Several also admitted to having their differentials replaced prematurely after visiting service centers, with no information from Toyota as to why.
