    I have a 2003 4Runner 4.0 with a ticking sound. It has 250,000 miles on it and I thought it might be the timing guides. However, after tearing down the cover off the front I really do not see anything wrong and I am at a loss. It runs good does not use any oil it just makes a sound like a sewing machine and has done that since me buying it about a year ago. Any help would be appreciated.

    I am almost ready to just put it back together and continue driving it!

    I thought it was the timing chain guides but they look good as does the chain, tensioner, etc.

    I am not sure as where exactly. Everything I read is the 4.0 is a noisey engine.

    Thanks for the insight.
    When I bought the 4 runner it had 229,000 and now it has 250,000
