Winnipeg Free Press (Newspaper) - May 29, 2015, Winnipeg, Manitoba C M Y K PAGE E8 E 8 WINNIPEG FREE PRESS, FRIDAY, MAY 29, 2015 AUTOS winnipegfreepress. com Q UESTION: I have a 2003 Chevrolet S10 with the 4.3- litre V- 6 engine. It runs rough, uses a lot of fuel, and when I took out the sparkplugs, they all appear black but No. 1 sparkplug was the blackest. I installed new sparkplugs but the problem still remains. Any suggestions? A: It sounds like you have a cylinder misfire. When a cylinder doesn’t fire, the unburned oxygen enters the exhaust system and is sensed by the oxygen sensor. The oxygen sensor then sends a lean mixture signal, even though it is a misfire, to the vehicle’s computer, which then richens the fuel to all cylinders. This would explain why all sparkplugs looked black. That black is carbon from unburned fuel. No. 1 cylinder is the worst, so that is where to start. Check to see if there is spark at the sparkplug by using a spark gap tester. If there is no spark, then it is likely a bad spark plug wire. If there is spark, then the fuel injector is likely leaking. You can test the fuel injectors for leak by installing a pressure gauge in the fuel system. It should go up to pressure when the key is turned on and engine stopped. It should then hold for about a minute. If the pressure drops off, then the injector is the most likely problem and will need replacing. Q: I have a 2006 Honda Accord, V- 6, with 99,000 kilometres on it. The problem has been described as engine knocking, or valve slapping. It is especially loud when the engine is cold. I would appreciate your advice on how to treat this problem, or any recommendations your might have to solve this problem. A: The Honda V- 6 engine has been a reliable performer over the years and there are no common problems with this engine that would help a technician identify an issue. A cold engine knock can come from a variety of sources. Piston slap or knock occurs when there is too much clearance between the piston and the cylinder wall when the parts are cold. Piston skirts are actually slightly oval and tapered so that the biggest part is close to the cylinder wall when cold to reduce any knock, but still allow room for piston expansion as the piston heats up. If a piston skirt has been damaged, possibly because of dirty oil, overheating, or hard driving when cold, then there is too much clearance cold and a knock occurs. To diagnose a piston knock, remove the fuel injector electrical lead from each cylinder one at a time while the knock is occurring. If the knock disappears when one cylinder is deactivated, the problem is with excessive piston clearance. It is possible to drive many thousands of kilometres with this problem as long as the knock disappears as the engine warms up. Just drive with light throttle during warm- up periods. Carbon buildup on top of the piston can also cause piston knock. The carbon hits the cylinder head when the piston is at the top of its stroke, causing the piston to tip slightly and knock. You may be able to see carbon on top of the pistons with a borescope through the sparkplug hole, but most technicians will clean out the carbon by adding a combustion chamber cleaner to the intake as the engine is running. This should be done carefully and slowly, as getting too much in too fast can overheat the catalytic converter. Valve noise is more difficult to diagnose, especially with the Honda VTEC valve train, but often you can pinpoint the noise area by listening with a mechanic’s stethoscope. Valve noise is usually a light ticking sound rather than a knock. Don’t rule out other knock sources. A bad engine mount can cause metal to metal contact and this can sound like an engine knock. An exhaust system touching the car body can cause the same noise, as can a cracked or broken air conditioning or alternator mount. These noises may only appear when the engine is cold because it is idling at a faster speed and perhaps not running quite as smooth as when it is warm. Listening with a stethoscope may help pinpoint the problem. You can even try prying the engine over with a bar to move it slightly during cold engine warm- up to see if the knock changes. If it does, then the problem is not inside the engine. james. kerr@ sasktel. net BACKYARD MECHANIC JIM KERR Cylinder misfire likely culprit for Chevy truck’s rough time Y OU often hear the phrase, “ Do it once, and do it right.” The Ford Motor Co. took that approach with the introduction of its new 1932 Ford. Henry Ford and his son Edsel came up with V8 power and offered it to the motoring public in a simple and cleanly designed car, that has stood the test of time. Today the Deuce is one of the most sought- after cars for everything from a factory restoration to the most modern street rod builds imaginable. The fact the ’ 32 was a oneyear- only design from Ford, they’ve become increasingly difficult to find and often need a great deal of metal fabrication to bring the body back into restorable condition. Enter the aftermarket. There are several companies producing the ’ 32 Ford bodies in both fiberglass and real steel, ready to be built with only final preparation and paint required. One company, Dearborn Deuce, in Branford, Conn., began producing a Deuce roadster body like no other in 2004. The Dearborn Deuce convertible is an all- steel roadster body redesigned around an amazing, fully disappearing top assembly. In order to package a top such as this, the original ’ 32 design wasn’t a starting point, so a new body was designed around a hide- away top. Several body design changes were made in order to package this top mechanism in a ’ 32 roadster, keeping them as subtle as possible, to preserve the original look of the standard vintage ’ 32 roadster body. For Lorne Kines of Winnipeg, owning a ’ 32 Ford threewindow coupe in the 1960s was a highlight, and one he often thought of revisiting. His dream was to have a ’ 32 convertible that was not only a turn- key show winner, but comfortable and driveable. In 2006, he was at Back to the ’ 50s and started looking at the build quality of many of the hot rods when he found Larry Ruth. Ruth has been building hot rods for 30 years and he owns L Ruth Engineering in Spearfish, S. D. “ I wanted a steel car, done once and done right, but without the hours of a new build from a project,” Kines says. After meeting with Ruth, Kines ordered the car the way he wanted it and visited Ruth several times during the 2,300 hours it took to complete the project. The Dearborn Deuce rides on a custom- built steel frame fitted with Kugel Komponents suspension. Unlike a typical A- arm suspension, Kugel uses twin pushrod rocker arms with hidden, inboard coil - over shock absorbers up front. Rack and pinion steering and disc brakes round out the package. In back, Kugel supplied an independent rear suspension with a Winter’s quick- change centre- section with inboardmounted Wilwood disc brakes and chrome coil- over shocks. With all components finished in either stainless- steel or chrome, it’s truly a work of art. Wheels are Billet Specialties knock- offs sized 17- inch up front and 20- inch in rear to give it that hot rod stance and are wrapped in Yokohama black- wall radial tires. The powertrain is as modern and reliable as the rest of the build and features a Chevrolet LS1 Corvette engine with electronic fuel injection. Backed by a 4L60E electronic overdrive transmission, it’s ready for the road. For the body, it’s been finished in base/ clear Brandy Wine and features a taupe interior, stitched with kangaroo leather and ostrich inserts. Inside, we find a stainless- steel steering column with cruise control, Vintage Air heat and air conditioning unit, heated power seats, keyless entry, digital dash gauges and power windows. The top itself is a highquality Haartz cloth in taupe. The rear window is glass with a chrome and polished stainless frame, giving the top that Old World look. It’s a roadster that can close up tight with the side windows and keep out any weather Mother Nature can throw at it. Finished in 2008, Kines has managed to roll up more than 6,800 kilometres on the roadster and has had it at several shows. It took top honours at the Fabulous ’ 50s Ford Club Flashback Weekend last September in Winnipeg. “ Do it once, and do it right,” is more than just a phrase. It’s a testament to the fact quality never goes out of style. 57ford@ mymts. net CLASSIC CRUISING LARRY D’ARGIS Quality and style ’ 32 Ford roadster done once, and done right PHOTOS BY DAVID LIPNOWSKI / WINNIPEG FREE PRESS Lorne Kines ( below) has rolled up more than 6,800 kilometres on his 1932 Ford Roadster.
