Leather interior, very || clean exterior. || My mechanic had recommended the four cylinder. He asked me "Why do || you need a six?" || Mechanical accessibility is important to me. || Not long ago completed major servicing, including timing belt || replacement. || An inexpensive electric impact wrench removed the crankshaft bolt, || whereas with the six, you often need an industrial strength impact || wrench to remove the same bolt. || Spark plug replacement is a breeze. With the six, it is never || pleasant because access is so much more difficult for the rear three. || Once saw a Camry up on the rack at a transmission shop. One of the || mechanics told me he saw a lot more sixes needing transmission work || than the four cylinder. || As I mentioned in the earlier post, if you like the six, just go || ahead and buy one. || This is an explanation of my preference for the four. || The four cylinder engine has five main bearings supporting the || crankshaft and for my version, a cast iron engine block. || I've got a four cylinder in my 1977 Toyota long bed pick up truck, || and that thing is still running strong with many hundreds of || thousands of miles on it. || Four cylinder engines of similar displacement today with turbo and || supercharging are putting out much more horsepower, so it seems that || even under the most demanding conditions for the 4 cylinder Toyota || Camry engine, it is not over stressed which contributes to longevity. || I kind of like keeping a car looking and running like new as year || after year rolls by. || Used to get comments on the truck, when I used to drive it more, than || it ran better than trucks ten years newer. || To the issue or question of power. || No question the six has more power. It produces both more torque and || more horsepower. || However, the four cylinder also produces power. To get the maximum || power, you need more engine speed. || Actually requires more skill and finesse in driving. || It takes me years to get comfortable driving a car, learning the || shift points, power curve, transmission and handling characteristics. || If you just want to be able to stomp on the gas and pull away || quicker, the six will do that. || However, if the four cylinder engine is spinning at 5,000 rpm, and || the six is spinning at 2,500 rpm, the four is making more power than || the six. || In actual driving situations, I rarely find conditions where the || power is lacking, and that includes pacing the new Nissan Z car at || speeds over 100 mph early one morning on an open stretch of freeway || while I discovered the transmission will upshift out of third at || around 95 mph at full throttle. || Bear in mind, during steady state cruising, you don't need much || power. Many manufacturers are adding features to disable some of the || cylinders for improved fuel economy at steady speed. || Part of the key to getting maximum power from the four cylinder || engine is to keep it in peak operating condition. That means running || a clean air filter, clean synthetic lubricants in the engine, || transmission, differential and power steering and having the belt || tension correct, with the secondary ignition system properly || maintained with the correct parts. || When I replaced the timing belt, I also replace the tensioner and || idler rollers, oil seals and water pump. Noisy idler bearings do not || help increase engine efficiency. || As many know, who read this group regularly, I also use Redline || complete fuel system cleaner to allow the valves, injectors and || engine breathing to operate at peak efficiency. || Once drove an ES300 Lexus with the six cylinder engine with probably || normal state of tune. Power steering fluid dark. Owner never checked || under the hood. Just took it to the dealer for servicing when the || reminders came in the mail. Didn't seem to have any more power than || my Camry. || Here's another overlooked item that adds power. Have the battery in || peak operating condition. Must be that I like additives. Used a || product from batterystuff.com, called battery equalizer with a weak || cadmium sulfate solution to reduce charging time, and discharge || rates, then charged the battery repeatedly. The alternator also got || new brushes with the timing belt change. If the alternator is || working overtime to keep the battery charge up, that's additional || drag on the engine. || Used to wonder how the modern fuel injection systems replace the old || carburetor based accelerator pump that squirts additional raw fuel || into the intake under sudden acceleration. Fuel injection is computer || controlled and always seeks to maintain the ideal mixture. The answer || is transmission downshifting that instantly bump the engine up higher || in the power band. So if one wants to drive the four cylinder Camry || faster, with more power, one needs to learn how to use the automatic || transmission more effectively. Shifting is controlled with the || position of the gas pedal and experience builds efficiency. Another || engine power tip, is to check cable adjustment so that at with the || pedal on the floor, the throttle valve is at wide open throttle. || Also, as stated in the earlier post, if you're often driving with || several adult passengers or luggage, you might weight the six more || favorably. || I've learned to always engage the ECT power switch when merging onto || the freeway. Recently, have found myself merging into 75 mph traffic || with enough power that I need to back off the throttle, but I don't || mind winding the engine up to 5,000 rpm, remembering the torque peak || is at 4,400 and the horsepower peak at 5,400. With the newer Camrys, || there's variable valve timing, so they produce more power all around. || Never had a problem hill climbing either. || Usually, one is just cruising along, and under those conditions, the || four isn't even using the rated power, just purrs along smoothly and || reliably. || Works for me.
WHY do you need to type THOUSANDS of words to excuse your grannymobile? Doesn't impress except to confirm that you so lack a life that you have time for keyboarding mammoth posts and time for spending hours on doing your own maintenance. Meanwhile, those of us with LIVES.........
