THANK YOU Mr. Martin:
I am very pleased with my purchase of your ratcheting timing chain tensioner. I have a 1991 Nissan D21 which I purchased with 140,000 miles. Over the past 20,000 miles, the engine developed the start up chain rattle and became worse. Then I discovered the cause of the chain rattle from your YouTube vids. You and I had a nice conversation, I purchased a ratcheting chain tensioner from you and from Nissan I purchased all the new original-equipment-Nissan replacement parts required for a new timing system and all the new parts needing to be replaced when replacing the timing system. Which was quite a project with the Nissan parts people over the phone, as Nissan does not sell a kit, they sell individual parts. So there was quite a laundry-list of parts I ended up purchasing from Nisssan. I was planning to do the work myself then decided to hire a well qualified and trusted mechanic to do the replacement of all these parts. It was discovered that at some point, prior to my having purchased the truck at 140,000 miles, the exhaust side timing chain guide had been replaced with a steel one with plastic coating. (As the original one for that year, which is all-plastic, was not present.) And the front cover had non-Nissan sealant. Interestingly, all the plastic on the exhaust side timing chain guide had come off the steel of the guide and was in the bottom of the oil pan, and the chain was riding on the steel of the exhaust side guide. What I suspect is that the timing parts had previously been replaced before l purchased the truck at 140,000 miles, with after-market timing parts, which only lasted a few thousand miles before failing. As I doubt that an original new steel and plastic exhaust side timing chain guide from Nissan would have failed so quickly. And after-market D21 timing chain replacement kits are easily available from most auto parts stores.
THE RESULT AFTER INSTALLATION:
Much quieter engine operation at all rpms.
Zero chain rattle on cold start-up.
Much better engine operation and torque at low and mid-range rpms.
With sincere appreciation for your vids, guidance over the phone and making these ratcheting timing chain tensioners, so we can keep our D21 trucks running well, Paul
