Are you thinking of the VW 1.8T maybe? They made plenty of those. Also yamaha has had alot of 5 valve per cylinder engines. On paper the 5 valver is better for the larger bore engines because they can get more valve area with smaller valves thus allowing the engine to rev higher because of less mass. But in practice it didn't seem to help much I know atleast with the yamaha raptor they went back to a 4 valve setup.
cost wise its its exspensive. Performance wise its been used in formula 1's since way back 80's and maybe even the 70's. But for today cars yeah 4 vavles crossflow design with a pent roof combustion chamber is the norm for todays cars. Also Audi or VW whatever you wanna say has made lots of em' the little turbo VW and Audi's all used em'.
Well, I stand corrected. I recall VW made a bunch of noise about their five-valve per cylidner engines a few years ago and I figured it was some limited-run deal that fizzled out. So all of the VW 1.8T engines are actually 20v...interesting.
probably right next to the spark plug or like in a diesel same location. Though its the type of fuel injection not head design on those. The super high pressure of the fuel system atomizes the incoming fuel which make it more effective or efficient. Which in turn makes more power. some one correct me if I'm wrong I'm drunk right now.[goofydrunk]
Plus having the fuel atomize in the combustion chamber provides a cooling effect that you don't get otherwise with injection in the manifold. I have one of those new saturn sky redlines with this setup it works well. Plus it gets 32mpg.
Can anyone tell me how to change the oil in the AT gearbox and which ATF oil to pour (which standard and from which manufacturers, probably Dextron III). It is a 4F27E transmission on a Ford Focus 2002, 2.0, petrol, made in USA.
Thanks in advance for the answers,
[?] Hey guys,
I've been getting a pretty bad 'stutter' when making a hard accelleration lately. So, I went ahead and changed my fuel filter. Everything went fine, but when i removed the fuel line from each end of the old filter, there wasn't a whole lot of pressure, fuel just kinda ran out of...
Anyways i installed my new valve cover the other day, and noticed my plugs are really old and rusted. Anyways i am buying new aftermarket wires to dress my engine up a little more next. I am thinking of getting these off ebay...
i leak oil out of the valve cover gasket, so i put a new one on and it still does it. i have spray marks on my intake. the engine smokes by the header where oil seeps out. i was wondering what could be causing this. my uncle a ford mechanic said that the compression rings were back and it...
