When to take cam chain tensioner shoes off?
You should not be concerned about inspecting them until somewhere between 80 and 100k. If you ever have your exhaust off before then, pull your cam cover and get a look at them. Just for piece of mind.
Why do I need a tensioned timing chain?
A properly tensioned chain is critical to maintaining the timing between the pistons and the valves. When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.
What did I do to my chain tensioners?
This past weekend I installed the new Screaming Eagle cam support plate, changed out the cam bearings (inner & outer), installed the new high volume oil pump and new style chain tensioners. I decided to go with the stock rods, and took them out through the top end. All related gaskets and o-rings were replaced in the process.
Are there any problems with the Nissan chain?
Nissan Timing Chain Problems. Certain Nissan vehicles are gaining a reputation for early problems in the timing chain system, including issues with the chain tensioners, guides, and shoes. Some have suggested that a manufacturing defect created timing chains with sharper edges that rapidly saw through their guides.
