Repair Questions and Answers
Question:
1992 Mazda B2600I mileage: 93,000. I have a
1992 Mazda pick-up model B2 600i, 4 cylinder, fuel
injected, It has 93,000 miles and has been well
maintained. My problem started about 2 months ago
and I have not been able to resolve it. The
problem is that occasionally the engine decides to
oscillate rpms when placed in gear (it is a manual
transmission), and on some occasions it takes numerous
start attempts to get the engine to run on its own and I
have to let it warm up for 15 minutes before being able
to drive it. Once running it will vary in power
when downshifting, while coming to a stop it will
suddenly lurch forward. This problem is not a
constant thing it just comes and goes. There is no
common time of occurrence, such as only when the engine
is cold or only hot etc. I have had a mechanic put
the engine on an analyzer and it did not reveal any
problems. I replaced the plugs, wires, fuel
filter, catalytic converter, and have added slick
50-fuel treatment along with running only 93-octane gas,
none of this has solved the problem. I am stumped
please help with some advice. Thanks, Ron
Answer:
From what you have described, we believe that your
problem is a faulty oxygen sensor.
Question: 1987 Mazda B2600
2.6L mileage: 150,000. I just completely overhauled the
engine had it bored out to ten thousandths of and inch,
put a remanufactured head on it, new pistons, cut the
crank with new rods and mains. When I reassembled
everything, I was extremely careful to torque every bolt
to the specs that I have in my repair manual. After I
got everything together and ran the engine, I found that
the engine was overheating with or without the
thermostat installed. I have good flow through the
radiator and no leakage past the rings or through the
head gasket. It is not leaking antifreeze anywhere.
Please help
Answer: Here are some things
to check. Is the ignition timing adjusted properly? Is
there exhaust gases in the cooling system? That can be
easily checked by a radiator repair center with a sample
of coolant with engine running. Is the fan clutch
engaging when the engine is hot?
Question: 1989 Mazda B2600
4x4, 150,000 miles. I want to rebuild the engine and
have the clutch replaced. There is no major problems
with either the engine or clutch; it burns some oil but
probably normal amounts for the mileage. What is a
ballpark figure that this would cost, and what are the
degrees of re-build; do I need to specify certain
procedures? What is normally done in a re-build? The
rest of the truck is in good shape. Thanks in advance.
Answer: The price for a
quality engine rebuild and new clutch, parts and labor
varies and you should get a few estimates. The following
labor should be done or parts replaced: hot tank block,
bore and hone block, new pistons and rings, regrind
crank, resize rods, new rod and main bearings, resurface
head, grind valves, new timing belt or chain, new oil
pump, new clutch and pressure plate, resurface flywheel,
boil and rod-out radiator and new water pump.
