Hi Rockroch :
How long have you had this problem ??? I am taking it to the dealer this saturday and will let you know what he has to say..... Have you been loosing oil at all ??? or have you been loosing coolant ??? these are some of the things that you might want to check... when was the last time that you got a engine tune up done ???? people say it might be as simple as "Tune up" to replacing your head gaskets...

Thanks for your reply. I just bought this car. I have three months of waranty on engine and transmission. I also purchased service contract on this car. I have talked to the dealer about this problem. He said it is perfect, just a few seconds to warm up the engine. As I did not drive much (I commute on subway), only found this weekend that there might be some leakage on the top of the engine, also the smoke seems to get worse. Everytime I started the engine, I will see a lot of smoke (blue and white) coming out the tailpipe, but it disappear in less than 1 minute. So far I don't know if it is losing ail or coolant, but I think I have to talk to the deal again.
Let me know what the dealer said about your car. Thanks, and good luck with your car.

I can only repeat: the car is most certainly NOT perfect. No car should put out any amount of smoke at startup, not for a few seconds, not for a minute, not while warming up...NOT AT ALL [I'm not talking about water vapor/steam that will be there for awhile before the catalytic converter gets fully warm].
I think this thing has a cracked head gasket on at least one bank of the V6. If that isn't it, then it's something else, but whatever it is, it is NOT the way it should be. No warranty is of any value if the people involved can't or won't find and solve your warranty-covered problems.
#125 of 367 Engine runs rough after highway speeds

I have a 1998 Toyota Avalon with 80,000 miles. The engine will run OK from 0 to 55 or so. If I drive the car at 70 mph for a short or long distance, it will run rough went the car slows down for a turn or a stop sign. I changed the spark plugs, the PVC valve and added injector conditioner to the fuel tank. If I step on the gas peddle in when the car is in neutral, the engine seems to smooth out at higher rpms. Can you suggest what I should check to correct this problem.

Here's a guess: replace the fuel filter. They cause funny things to happen when they begin to get clogged with trash....

I concur, fuel filter. Toyota claims it is a lifetime filter....But please??? You may have gotten some real dirty gas.
#128 of 367 Valves Clicking
May 26, 2005 (6:37 am)
Recently I've started hearing what sounds like my valves clicking. I thought it may have been pinging so I ran a couple tanks of Premium in it with no change...so I'm assuming valves. A mechanic I met said he's seen it before and it's caused by a plastic part in the valve train that gets messed up if the engine overheats. It's easy to replace. I did have the sludge problem at about 24,000 miles (about 24,000 miles ago) which the dealer took care of free of charge (it was out of the 3 yr warranty by that time).
Anyone else heard of this problem...or solution...or have any advice? I've never dug into this engine but i've dug into plenty of others and don't have any qualms about popping valve covers off and tinkering around inside.
Thanks in advance.

Two weeks old 2005 Avelon limited with 185 miles. It had 10 miles on the odometer when I bought it. It was smooth and started without any problems about half a mile on the road it gave a knocking sensation for about 5 seconds and stopped on the road. Before stopping it lost steering power and brake power. I was lucky not to get in to an accident Car was driving at about 35 miles/hr on auto mode at that time. I had to tow the car to the dealer. They are yet to look in to the car. Do you know what could cause this. I feel uncomfortable with this car after going through the above. What can I do?
