What to do about blown head gasket on Toyota 4Runner?
The FSM says remove the engine, then oil pan, timing chain, then heads. The Haynes does it without removing the engine, but still removes the chain. I just wonder why someone hasn’t tried it – is there some impediment?
What are the problems with the Toyota 2.4L engine?
This engine consumes oil quiet significant due to the wrong piston rings design for North American Toyota models. Oil consumption usually starts after 45-50k miles. 2. The widespread problem is what cylinder head bolt threads wear out on back three middle bolts. This problem can be identified by coolant leakage from the rear end of the engine.
What causes an oil leak on a Toyota 3.4?
Oil leaks are part of the nature in owning an older car and engine. The valve cover gaskets on the Toyota 3.4L are one of the more common areas to experience leaks. These gaskets are subject to lots of stress and heat cycles during their lives. Over time, the 5VZ-FE valve cover gaskets begin slowly cracking and leaking small amounts of oil.
When to change valve clearance on Toyota 2.4L?
The adjustment of valve clearance is required every 60,000 miles (100,000 km). These two engines are almost identical expect the displacement. In 2008 the engine was redesigned. 2008+ engine produces more power and torque. The compression ratio rose up from 9.6:1 to 9.8:1. The engine got new camshafts rising red line to 6,500 rpm.
Where are the coolant hoses on a Toyota 4Runner?
There are also two coolant hoses going to the back/middle of the engine near the firewall so check those. Look for coolant trails because sometimes it can be leaking out of the water pump or thermostat and the wind will blow it back towards the steering rack.
