I bought my '90 Toyota pickup Deluxe earier this year without knowing much about it, aside from the fact that it's 22R-E engine was considered to be one of the most reliable engines made by Toyota. With 141,000 miles on it, I quickly found out I needed a timing chain. The driver's side guide had broken, as is typical. I bought and installed a replacement chain kit from Toyota which included the chain as well as new guides, pulleys and the tensioner. I was amazed at how much quieter the engine has run since the chain slap has been removed. Here's the rub though: I still get anywhere from 0 to 2 seconds of chain noise when I first start the truck. The most I ever hear is 5 distinct "ticks," and sometimes I hear none. It's almost like my tensioner takes a few seconds to get oil pressure and take the slack out of the chain. Is this common? Is this going to greatly shorten the lifespan of my chain and guides? What is the chain actually hitting to cause the noise? And is there anything I can do about it? Any help would be greatly appreciated! Thanks!
