That is caused by an over fueling condition, you need some testing done.

Installed new TD04 turbo and vehicle ran perfect for a week or so. Last night drove 10 mins it is revving to fast and when i looked at exhaust manifold it was glowing red.


I would check your MAP or MAF sensor to be sure. Sounds like you are running lean which is causing your exhaust gas temperature (EGT) to be very high. Running lean with a turbocharged car will destroy your engine very quickly. Drive the car gently until you figure this out.
P0109 OBD II Trouble Code

Also, it is common for the exhaust manifold and downpipe to glow orange if the car has been driven in a spirited manner. Although, normal (not lead foot) driving shouldn't cause your EGTs to be this high.

What cause my 2000 lexus es 300 exhaust manifold to get hot


The exhaust manifold is going to get hot, this is where the engines exhaust flows through. these tempertures reach high temps,

If the manifold is glowing hot then theres a problem.

Sometimes people say the manifolds are getting to hot because they see them smoking. The reason on most of these cases is due to a leak, aleak from a bad gasket like a valve cover gasket. Engine oil leaks down on to the exhaust manifold causing smoke. make sure there are no leaks .


A few reasons that would cause exhaust manifold to heat up more than normal would be a engine thats running rich, this may be due to a leaking injector or a poor running engine. Another reason may be that you have a plugged cat. converter.

The Exhaust manifolds can reach about 600 degrees, the last thing is people hear the metal expand or contract and think there are getting to hot , this is normal.

Please let me know if there is something else i can help you with. thank you and have a good day.

When driving i can smell gas in my 2000 lexus es300


possibly your O rings which isolates fuel injectors from engine block are getting old and letting gasoline go out. it is very dangerous since it can cause fire. do not drive.

another cause is broken loose or cracked fuel lines. this is equally dangerous since it is under hood close to hot exhaust manifold.

if smell is from exhaust manifold, which means not the smeel of gasoline but exhaust fumes, this can be caused by broken exhaust manifold or a crack on it or problematic exhaust manifold gasket.

How much does it usually cost to get a cracked exhaust manifold fixed. 1994 es300.


that is not a common problem for a es 300
have you checked for loose manifold or broken manifold bolts? also they will blow out a piece of gasket depending on if they are metal or paper.it depends on which side of the engine that needs replaced if it is crack.

Check engine light on in 93 Lexus


The only way to check why the check engine light is on is to have autozone or a mechanic put a scanner on the car and read the engine codes. This will tell you exactly what is wrong. Many part stores will test it for free. Mechanics will charge about $40 But you will definately know exactly what the problem is.

If gauge is fine and car smells hot. It is probably due to plugged exhaust unless you have a wire laying on the exhaust manifold and it's melting.
