Toyota Exhaust Problems
When is it recommended to replace the exhaust pipe and manifold on a Toyota Sequoia?Older Sequoias and Land Cruisers are known to have problems with leaking exhaust manifolds. Although not typically noticeable and not a safety issue, it can cause the check engine light to come on or a faulty oxygen sensor reading, that is when the replacement can be considered.
What is the cost to replace an entire Toyota exhaust system on a 2001 Highlander V6?The front Toyota exhaust parts such as the manifolds and crossover pipes (including the converter) are “dealer” only parts so they may be expensive and should be replaced only by a dealer. But the rest of the Toyota exhaust system is made up of pipes and mufflers and any exhaust shop can replace these quickly and at a lower cost. All total should be less than $3500 and it is always good to get more than one quote.
Why does blue smoke come from the exhaust pipes of a Toyota 2008 Avensis2.2D4D only when it is driven inside the city?Blue smoke is usually an indication of burning oil caused a problem within the Crankcase Pressure Relief Valve. These are spring loaded and are supposed to open only to allow excess pressure to escape once in a while. The exiting gas is piped back into the inlet but if the valve is stuck open then the air, along with the oil in it, is sucked into the engine where it burns. Check to see if oil is present where the crankcase breather is plumbed in. The valve should be replaced. If this is not the problem, then check to see if the valve stem seals are worn and are allowing oil to drip into the intake and need replaced. If there is oil in the intake after the turbo, then the turbo oil seal may be failing and need replaced. Finally, an engine flush will clear a sticking oil scraper ring. And if the problem remains, then using slightly thicker oil may help as this will not be drawn into gaps as easily as thinner oil.
, Should the exhaust manifold be replaced if there is a ticking sound in the exhaust system of a 2000 Toyota Tundra when the engine is cold but is stops after the engine has warmed up?If the noise stops when the engine and exhaust warms up then the cracks are small enough they seal with heat and the manifold will not need replaced immediately. However, with cracks close to the cylinder air could be drawn into the pocket around the exhaust valve and could lead to hot spotting of the exhaust port and then burn up the valves. It is common for this noise to remain for up to 60,000 miles with no effect on the vehicle. If the noise becomes constant then replacement of the manifold is necessary.
Toyota exhaust systems do not often require maintenance or repair. However, if issues arise and are ignored it can affect the performance of the vehicle and also the amount of pollution the car creates increases If the repairs are not done correctly, the resulting damage could cause even more expensive repairs.
