sniperwolf: I've been guilty of this act countless times. I just want to know if there are dangers starting a car with the air condition ON.
One time my dad was in the passenger seat and noticed that I had started the car with the A/C ON, he made me felt bad.
Back to my question, and DANGER? And how often do you do this?

lonelydora: A Friend drove my car and to my greatest surprise pulled out the top button of the gear stick. I Am the one that unscrewed the plastic covering so that I can move the car.

How can I get a new one or atleast repair the old one? That is, I need only the plastic covering with the button. Answers needed Urgently please.

Ifeaka32: Please recommend sound automobile engineer to handle my highlander hybrid issues. Thanks

lomomike: DOHC is a type of engine/cam design DOHC means Double Over Head Cam (where two Cams placed over head operate the various valves both intake and out take/exhaust valves). Now there are 2 camshafts per header. So in an inline there are 2 camshafts because there is only one header, but there is 4 in a V-type or flat engine. These DOHC engines usually have 4 valves. One camshaft for the exhaust valves and the other for the intake valves



SOHC means Single Over Head Cam (Only a single cam rod operates the intake and out take valves). That means that there is only one camshaft per header. Inline engines will contain one camshaft. V-type and/or flat will contain 2 camshafts. For a SOHC engine there are usually 2 valves per cylinder but there can be more with the addition of cams for each valve.



When you compare their performance you discover that SOHC engines develops a little less power than its DOHC brother, but it develops more of its power earlier and is therefore more flexible and generally more economical. The DOHCs rev much harder and higher, and at mid to top revs develop much more power for the same displacement engine, making them ideal for racing or performance vehicles. And if the DOHC is a V-engine, like a V6 or V8, it could be called a Quad-cam.

SOHC engines are cheaper and less complicated to design, build and maintain because of the lesser moving parts, while DOHC are more complex to design build and repair because of the extra moving parts.

Another advantage of having a DOHC engine over a SOHC is that the engine has twice as many intake and exhaust valves as a SOHC motor. This makes the engine run cooler and more smoothly, quietly, and efficiently. But the downfall is that DOHC engines cost more for repairs.

watino: i based in enugu and have original ngk plugs, it will cost you 30,000 naira.

adanny01: I thought there is an adjustment but the mechanic told me not and tried to bleed air. The clutch stopped working altogether after bleeding. There was no leakage whatsoever.

I didnt anticipate spending 20mins in the garage but ended up spending 4hrs cos the car wouldnt move.

halmat: I have already siezed this my year 1 holiday learning from an apprentice in our locality, but want to know steps to become a professional in the field like yours.

chuqudy: You like high mileage cars, so I suggest that any one whose odometer reading is getting to about 1000 miles, should sell the car to you immediately.

chuqudy: So for your mind you don do correction abi? When a car reaches that highest mileage which it can go, would it not STOP MOVING? Abi it go continue from where it stop. Now over to you. Answer your question, "what's the highest mileage a car can go?"

I know your answer would still be your old silly answer. Keep it up!!!

chuqudy: To car-doctor offcourse. That quack doctor.

DanNafada: You are perhaps too smart for your own good.
The question was not silly. It was an interesting question that he simply did not ask in the right way. Hence my suggestion.

DanNafada: Indeed no such thing as a stupid question on a forum. We are all here to learn. That said, the question perhaps should have been:

What is the highest mileage a car can go before it permanently breaks down?

lamex20: @car-doctor u're senseless ... d poor guy only ask a question, insted u answered as a bamboo
