I've been having some problems with my 1996 Toyota Tacoma 2.7L truck. The first problem is sometimes when I start the truck I get an extremely high pitch squeaking noise from the belts. It's as if the belts are soaked, and completely worn. The strange part is I replaced the belts with new ones this past winter. Even stranger is it squeaks really bad (you can hear it down the street) for about 30 seconds than just COMPLETELY stops. You can also hear it if the steering wheel is turned all the way like when parking. This happens regardless of weather or temperature. It doesn't happen all the time, maybe 50/50 chance of it doing this. I think it has to do with the tensioner not being correct, but I'm open to other suggestions.
My next problem, is the past couple days, I've been hearing a knocking or putting noise from the engine. I attached a sound video clip of it doing it. I have no idea what it could be? Maybe it needs a valve adjustment is what I'm thinking? I'm not sure when or if that was ever done.
Other issues I've had was at times it could be hard to start, especially after loading the bed up with heavy items. I'm not really sure why. I do know my sister had a car that would have problems starting like this, and it turned out all it needed was a new fuel filter. I bought a new fuel filter for the Tacoma when I tuned it up last winter, but I never was able to install due to the difficult position.
I'm thinking about taking it to to a mechanic to install the fuel filter, but any insight into the other problems would be greatly appreciated.
