I'm not totally familiar with the way Toyota has implemented their emission controls, but if it is anything like the Honda S2000, then the noise may be an air pump. When the engine (and catalytic converter) is cold, the ECU will run the engine very rich so that there is unburned fuel in the exhuast stream. The air pump would provide fresh air to mix with the unburned fuel so that it would ignite in the catalytic converter to heat it up quickly. Once the engine is up to temp, the ECU will quit running the engine rich, and shut the air pump off. Take it for what it's worth, since I have no idea if Toyota implemented this "feature".

 

30 seconds and go.

 

i just start it and go, i dont think that it will make that much difference.

 

No air pumps on Toyotas that I've seen, definitely not on the 2GR-FSE. Not even an EGR is necessary now that they've got VVTi.

 

I usually warm it up for like 5-10mins...i know i have a lot of time on my hands...

 

I hope you change your oil often to get rid of all that contaminated oil.

 

I do the exact same thing. Weird coincidence, but I also drill and fill

 

For the cold Canadian Winters, I've followed this tried, tested, and true method for years:
As soon as I'm out of the shower and still in my towel, I run out in the garage, start the engine. Then, I run back into the house, get dressed, comb my hair, and with a croissant in hand, I get in my car and drive off. By the time I'v done everything and get to the car, the temp guage is past the C mark. Perfect! Everyone should use my method!

 

Obviously, it is tried and tested by you, but I don't see any sense behind it. Try "proving" your method by a used oil analysis in the spring. I think you'll find that your oil is heavily contaminated. Why not just use a block heater?

 

With the LS i walk into the garage, start the engine, open the door and drive off like normal, without worrying about the tempatures...because i rarely drive the car and when my mom drives it she doesnt care either. Ive tried to tell her to be easy on it when its cold but never really works. With my Truck When i start it, i make sure it stays on for at least 10 mins. But i dont Idle it i just drive.

Lets just say im going to go to the dunkin donuts 3-4miles down the road. I will start my truck - drive there - leave it running while i run in and grab the donut and get back in and drive home/to school. I dont idle my truck to warm it up but if its not up to tempature, i dont repeatedly start/stop it for short trips.

 

I think depeding on the car, it might be good to warm it up first. The other day it was like 15deg Farenheit here and I started the car and waited for 1min. I put it in reverse to back off and then put it in "D" and the car stalls!! It didn't move at all. I hit the gas pedal a little bit and the engine would make more noise but, the car would not go forward. I finally stoped the car in the middle of the parking lot waited for 5min to come to temp. and then drove off...

Cold weather = Frozen Transmission Fluid, on that day!

Oh by the way, I was driving my '91 Accord EX. I don't know how it is with the 2IS, since I am still waiting to get it...

 

why would my oil be more contaminated then anyone elses? All warming the engine does is allow ur car to reach normal operating temperature, as its also healthier for your engine.

 

No it isn't. Idling is the worst thing you can do to an engine, especially if it is cold. All the humidity in the engine condenses on the sides of the engine and the organic acids in the blowby dissolve into the water. The water then drips down the sides of the block and sits on top of the engine oil. The acids in the water attack the oil and cause it to sludge and break down prematurely.

You are FAR better off to just drive the car and get the oil fully heated and move some air through the engine (via the PCV system) to clear out the water and acids as quickly as possible. Or suffer sludging and corrosion. It's entirely up to you.

 

what do u suggest is the best way to warm up ur car?

 

I'd say it depends on the temperature outside too... If it is TOO (BRRR!) cold, than you should wait like a 1-2min for the trans. oil to warm up. Otherwise, just start and maybe wait a couple seconds and go! Also, REMEMBER to take it easy on your car if you take off in few seconds!

It was like 15deg here few days ago, I started my Honda and waited for few seconds, put it into "D" and my car would NOT go forward because the transmission oil was frozen. So, I waited awhile and I was off...
