It keeps overheating i think its my censors. And its been burning oil fast what do you think is the problem

I would highly recommend to change the thermostat. I have a Toyota Dolphin RV had similar symptoms. Thermostat was opening but not fully opening. Change thermostat runs at normal temperature now.

A car that keeps overheating should not be driven.

Light blue smoke is burning engine oil. This is probably a sign that overheating has damaged the engine.

Water pump can leak coolant, make a noise and even wreck the engine under some circumstances but they have little to do with engine oil. If the water pump leaks it is an external leak.

If there are no external coolant leaks then yes it could be the head gasket or perhaps a crack somewhere...

the HONDA Horizon (Isuzu wonder box)
what engine. exactly .?
3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4
x1 or G2?

floods, wot cranking cuts fuel and starts any flooded engine,
it's overheating that wins the First order failures rule sets.
nothing else matters. cure that first.! find cause! first.

sounds (im deaf there,lol) that smoke is out tail pipe end and dissipates fast and is not smoke but steam, , oil smoke smells like burning oil and lingers. steam smells sweet like burning Antifreeze.
AF steam is a blown head gasket or far worse.
do a compression test first to see if it's even worth fixing????
most are NOT. (unless free labor, sure)

first learn steam from smoke
serious , watch moms tea pot. see that steam goes away fast.and very uniquely , now watch burning oil.
remove dip stick, drop the drip of oil on hot exhaust manifold.
smell that, that is oil burning, and lingers.
this will last you a life time of blown engines..... just one look and bingo. (my instructor in 1965 did in front of class)

got oil in the AF/ CARBON chunks in same.
water in oil, ? pan, engine . milky oil.
rad leak down test fail? can be lots of reasons even a cracked block.or head. not just gaskets.

wow no year, no country and no engine stated, now that is a challenge. no engine mileage either, 50k or 300k? miles>?
so what makes you think its burning oil.?
long lasting white cloud behind you and EPA (MOT) in hot pursuit?
or every week oil level drops (can )
my guess is drop only.
so HOW many miles for 1/2 qt loss.?? that be first.
all cars burn oil , all do !
and the faster you go , the more so. how fast? do you go, here in dallas we
have a 85mph freeway with folks doing 90 allday.
they burn more. oil;.here. sure do.

Serviced for MOT< that means CANADA right?
we dont have MOT in the USA this forum is USA (calif)
here its smog stations, EPA regulated.

did they put in very thing oil in your car?
like 0w ?
the thinner oil can walk past the lower oil control ring
and down leaky valve seals.

also get a new PCV valve and keeping pressures down this
way cuts oil consumption.

is this car new to you?
the driver must learn his/her oil usage by checking oil
about every other fuel fill up. then learn rate of burn.
and add it , when at 1/2 qt low , learned in advance.
predict it and win.

buy 4 qt.
fill to top mark,
always buy extra oil, so you can keep it full , im sure any 92 burns oil,tad more than new.
or if you drive fast , it sure will burn more.
fsm quote 3.7qt

check coolant and oil level,could have coolant going to oil or burn the oil.

Sounds like the oil control rings on your pistons

You need to have fault scan to identify what sensor triggered light. Reduced Engine power is telling you that it's in LIMP mode.

Check the obvious things first, are you low on water? are you low on oil? are you over heating, if these all check out then you probably have a defective censor somewhere. emission censors can do this also. Oil sending unit, water temp censor, etc.

i pretty sure thats a head gasket. black smoke comes from burining oil. white smoke comes from burning antifreeze.
