Timing Chain Stretch: It Could Be Neglected Oil Changes And The Wrong Oil
Timing chain stretch is not the stretching of the timing chain, it is an elongation of the timing chain caused by wear to the chain’s components. The most common cause of timing chain stretch is lack of maintenance and regular oil changes.
VIDEO: Diagnosing Intake Manifold Gasket Leaks

Tech Tip: Fixing The Honda Accord, CR-V Rattle At Start Up
If a Honda, including the 2008-2012 Accord, 2012-2013 CR-V, and 2012-2013 Crosstour, has a pronounced rattling noise emanating from the engine during cold start-up, persisting for approximately two seconds, then this symptom is typically indicative of a defective Variable Valve Timing Control (VTC) actuator, as outlined in Technical Service Bulletin (TSB) 09-010. The corrective action
Turbocharging: Managing Pressure In The PCV System
Crankcase vapors are routed through the positive crankcase valve (PCV). The PCV valve is a simple spring-loaded valve with a sliding pintle inside. The system allows the vapors to be siphoned into the engine using engine vacuum.
Diesel Coolants: The Right Fluid For The Right Application
Which antifreeze should you use in your diesel engine? It seems just when you think that things are starting to settle down, some spec changes. Engine oil has been a hot topic over the past several months and has seen many changes over the past 10 years.
Curing Carbon Deposits On Direct Injection Engines
Direct injection improves fuel economy by injecting the correct amount of fuel for the conditions in the combustion chamber. But, it is not a perfect science: Carbon deposits can form on the intake valves, piston and other surfaces in the combustion chamber.
GF-6 Delayed Again: What Does It Mean For You?
If you’ve been waiting on the first license for the new GF-6 oils, prepare to keep waiting. This new oil spec that was first slated to be licensed later this year, and later postponed until April 2018, has now been projected to be delayed until 2019.
Rear Main Seal Diagnostics Q&A
Solving why the seal failed in the first place is critical to preventing a labor-intensive comeback. Here are six questions you should be asking yourself before, during and after a rear main seal job.
Diagnosing V8 Engine Leaks
You already know that there are plenty of BMWs with V8 engines on the road today, but you might be surprised that they can have issues with oil leaks. Inevitably, some of these will find their way to your shop in need of service, so here are some common items to be aware of when they arrive at your shop for repairs. In this article, I will focus on valve covers, the front upper timing chain covers and the alternator bracket gasket.
Ford Diesel CK-4 And FA-4 Statement
On Dec. 1, 2016 the American Petroleum Institute (API) began licensing two new diesel motor categories: CK-4 and FA-4. API CK-4 was released to replace CJ-4. FA-4 is a low-viscosity diesel oil released for diesel engines designed for such oils.
VW VR6 Head Gasket Replacement
The oddest things about the VR6 are that the narrow angle between cylinders allows the use of just one cylinder head for the six cylinders, and the timing chain is located between the block and transmission.
Timing Chains In Hyundai Engines
Although Hyundai uses a single timing belt on its 2.7L V6 engines, its 3.3L, double-overhead camshaft engine is equipped with one timing chain for each camshaft and one drive chain for the oil pump. At first glance, a timing chain design allows engineers to shorten the overall length of the engine and reduce rotating friction.
