Consumer Description

Defective sealant used on timing cover, already leaking engine oil at 85000km… also confirmed as the same engine prone to cylinder head cracking from poor casting dimensions resulting in engine oil contacting the exhaust manifold and smoking. Possible fire hazard. Engine can seize up from low oil pressure at highway speeds and lock up the wheels causing an accident. Not sure why Mazda hasn’t issued a recall for this obvious safety concern… reminds me of Hyundai/Kia engine problems and now they’ve been sued and replacing thousands of engines for free.
