Clicking Sound

I have a 1989 Toyota MR2 with 114,000 miles. This past week when I
have been driving there is a loud clicking noise. It only makes this
noise when I'm in gear though. Does any body know whats going on?

Does it happen when you are moving or sitting still? Turning or going
straight?

Also, what area of the car is the clicking coming from? Is it related to
vehicle speed, engine RPM, throttle position, clutch position, etc?

It happens when I'm just driving. It only happens when it is in gear
and Im pushing on the gas. I have tried reving the engine to see if it
will do it and it won't make the sound that way. It sounds like its
coming from the engine compartent somewhere. I know its not from a
lack of oil because I check that every day and its hardly ever low.

If it is a rattling sound from the engine, then it could be pinging caused
by bad fuel, bad knock sensor circuit, insufficient ignition timing advance,
incorrect base ignition timing, or engine deposits.

It is also possible that the rear CV joints are going bad, but that sound
generally changes as you go around corners.

I think the car is done for and you ought to sell it tro me for $200...

Sorry.. ;)

In the grand scheme fo things...
What difference does it make?

Sorry hachiroku the wheels and tires are worth more than your 200. And
the body is in good shape. You'll have to offer more than that.

I'll get the engine checked. The sound doesn't change when I turn.
I'll get it fixed I like this car too much to get rid of it.

Most obvious thing would be one of your inner CV joints, but its not like
you made much of an effort to describe the sound. Is the noise related
to wheel speed or engine speed? Does it happen in reverse? Is the
sound affected by turning? Is there anything that seems to effect the
amplitude of the sound?

The sound isn't really related to speed. The speed of the clicking
doesn't change with the speed. I haven't heard it in reverse before.
And turning doesn't affect the sound at all.

Sounds are very difficult to diagnose without actually hearing them. If it
is not related to engine speed, check the cooling fan and other rotating
parts.

Listening to it today it actually seems to get louder when you press
the gas in more. I do think that it could be a lifter but I'm not sure
on how to diagnose that.

If the sound is coming from a lifter, its frequency will be directly related
to engine RPM. Use an engine or a screwdriver with a long shank and listen
to the valve cover and see if the sound is coming from the top of the
engine. To use a screwdriver as a stethoscope, place the tip of the
screwdriver directly in contact with the area you want to listen to and put
your ear against the handle. The sounds will be transmitted up the
screwdriver shank to the handle to your ear.

I believe your engine has solid lifters so if the lifters are the cause, a
valve clearance adjustment is in order, which requires an assortment of
varying shim thicknesses on hand.

If the sound is coming from the bottom of the engine and is related to
engine RPM, the fix is going to be expensive.

I'll have someone listen to it outside the car tomorrow. The engine is
a T1600 if that helps at all.

Sorry, have to actually listen to the sound to make an intelligent guess.
