7. Toyota Model: Corolla T-spirit 1.6 2002. Posted April 30, 2005. I have read lots of threads regarding heavy oil consumption on the various. versions of the VVT1 engine. In my case it concerns the 1.6 VVTI fitted to a 2002 Corolla T-Spirit. This engine is consuming over half a litre of oil every 1000 miles.
The Toyota 2AR-FE is a 2.5L inline-4 engine first released in 2008. It's an engine option in the Toyota Camry and RAV4 even to this day. 2AR-FE engines offer 169 to 180hp. It's not a lot of power by modern standards, but it's enough for the purpose the engine serves. The 2AR-FE is a smooth, reliable, and efficient engine to safely get you
1) Toyota 3.5L V6 Oil Leaks. Engine oil leaks may come from several different areas. However, the most common oil leak on the 2GR-FE primarily affects models up to 2010. The variable valve timing (VVTi) system uses a rubber hose that feeds oil to it.
The 1ZZ cylinder head features laser-clad valve seats. The intake valve diameter is 32.0 mm diameter and its valve lift is 9.3 mm. The exhaust valves have a 27.5 mm diameter and 8.4 mm lift. The overhead intake and exhaust camshafts are chain driven. There is an 8 mm pitch roller chain which goes with an auto tensioner. The EGR valve becomes clogged and accelerates the formation of carbon deposits on the cylinders, which leads to an "oil burn", which is approximately 500 ml per 1,000 km. There are problems with a leak in the cooling system pump and a knock in the VVTi couplings during a cold start of the engine. However, engine failure is most common among 2011-2014 Hyundai Sonata and 2013-2014 Santa Fe. Problems also affect the 2.4 Theta II engines in some Kia models of similar years. This includes the Optima, Sorento, and Sportage. We won't beat this topic to death since it's been covered quite a bit. yielp.
