We caught up with Billy Godbold to discuss all things camshaft.
Angel Robles has been appointed as VP of business development in the U.S. by Kelford Cams.
Andrew Markel discusses flywheel jobs, and how to improve the precision and line-up of the components after it is finished. Sponsored by Auto Value and Bumper to Bumper.
The late-model Nissans have proven to be quite reliable when it comes to serial-type problems that would get them to your bay with check engine lamp issues. Nissan has done a good job of addressing some of the problems we’ve looked at in the past. But that doesn’t mean you won’t be seeing Nissans looking for attention, and that spells service opportunities for you.
Choosing the “right” camshaft is not only the cornerstone of building a performance engine, but also its centerpiece. Choosing a cam can give anyone a headache – especially if they choose the wrong cam for a given application. There’s a lot of science involved in cam selection, so keep reading and we’ll help you wade through the details.
As I removed the timing belt and balance shaft belt, I noticed this soda can tab holding one of the crank sensors in place. Apparently, the customer knew of this from a year ago when the balance shaft belt broke but couldn’t afford the sensor or a new water pump.
When the topic of variable valve timing (VVT) comes up in import repair shops, few realize that the concept of increasing low- and high-speed engine torque by automatically advancing and retarding valve timing isn’t a recent development. For example, I recently discovered an old variable camshaft timing gear that I bought during the 1960s featuring a torsion spring device that retards valve timing in response to the increased rotating torque needed to turn the camshaft at higher engine speeds.
Due to the ability of Nissan’s variable valve timing system to provide increased engine performance, Bob Dowie offers his diagnostic, electronic and mechanical expertise for how import vehicle specialists can most effectively perform engine service.
Hall effect crankshaft position (CKP) and camshaft position (CMP) sensors are critical components of an engine management system. The inputs they provide enable the powertrain control module (PCM) to determine engine speed and position including where a given cylinder is within the four-stroke cycle.
Rated at a rather anemic 210 horsepower, the 4.0L SOHC V6 is not exactly a high output engine. It also has an unusual overhead cam drive setup. Unlike most other OHC V6 and V8 engines that drive both overhead cams directly from the crankshaft with a belt or chain, this engine has an intermediate jackshaft in the middle of the block where a pushrod cam would normally be located.
