how difficult is a valve adjustment on a 3EE Toyota?

Hi All,

I have a 1994 Tercel that a friend asked me to sell. It is making a loud
tapping noise that is coming from the valve cover, it sounds exactly like a
stuck hydraulic lifter. However in my research this car has the 3EE engine
which has no lifters?

I'm guessing it is just that it needs a valve adjustment, the engine also
idles rough like it has a cylinder miss, and that cooresponds with the
frequency of the tapping.

Plugs on this were oil fouled and it failed emissions with high THC of
2.48 g/mi MAX and very low CO, of about 3.4 g/mi MAX, I replaced
the plugs and put new wires, cap & rotor on it, it still fails with high THC
which is now 4.2 g/mi but the CO has gone up to a more normal 26.4 g/mi

Apparently the owner got it to pass inspection for the last 2 or 3 times
by replacing spark plugs and pouring in a bottle of drygas to the fuel tank.

Unfortunately the owner (like a lot of people planning to sell a car)
pretty much ignored maintainence on it, it was low on oil and the oil was
pretty black, I changed it. The oil level is at the F mark and the tapping
noise
started up about 3 miles after changing the ignition components and about 40
miles after changing the oil. At least the engine did stop smoking after
changing
the ignition components.

I'm pretty much at the end of what I want to spend money on it, so
suggestions like replacing the head is pretty much out. The new owner can
do
that. Would there be a chance of getting rid of the tapping noise with a
valve
adjustment or getting it past emissions?

You're not supposed to run your car on hash oil.

I guess you don't know that the BAR 31 test method part of
the EPA designated Enhanced test uses the acronym THC
to indicate Total HydroCarbons. Maybe someone who worked
at the EPA and designed that test partook of the herb?

It's an unfortunate acronym. Sort of like the British term for
limited-slip differentials: LSD.

Hmmm. THC, LSD... Cars are fun, aren't they?

Toyota has made lots of high-quality reliable vehicles. That Tercel
is NOT one of them. It's a lost cause.
