If your vehicle has been running roughly or seems to be losing power, it's possible that there's a lack of pressure in one or more of the cylinders. Without enough pressure, the fuel/air mixture doesn ...

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a ...

A four-stroke (or four-cycle) engine is so called because in the process of producing power, the piston passes up and down the bore four times. These strokes or events are the induction, compression, ...

While we like to think of 2002 as being part of a high-tech age, our beloved internal combustion engine hasn't really changed much in the last 50 years. We're still using pushrods and overhead valves, ...

Your compression test should have told you if it was bores or valves. If it really was a compression problem though, I wouldn't expect it to be "ok sometimes". BTW oil additive flushes such as Wynns ...

You'd think that the pistons listed for a 10.5:1 compression ratio would actually give you 10.5:1. But it's usually not that simple. Perhaps that's why so many four-wheelers have a foggy or incomplete ...
