That is quite possibly true, You should try running with the oil halfway between the add and full marks and check it HOT

I had had the clutch replaced on my 2007 Suzuki swift sport due to an oil leak on an oil seal at the top of the engine but the problem has come back is the another seal on the gearbox that should have been...

automatic trans right?not stick, both have clutches.!!
so you want us to guess leaks.?
well is it ATF leaking? or engine oil>?>
pink or brown, oil>?
finding A/T leaks is no easy task,
some seals will fail again if the TC is not swapped out.
the seal runs on a metal surface there, and most not be damaged
the pump is there and it can leak.
finding it is no easy task, and very expensive.

find a mech, that will find it
clean it all , drive for 5 miles, see leak now? way 1.
use dye IR light methods
buy the dye kit and put it into the unsaid oil source.
ask any mech, on earth to ID that oil, ATF, GL4, or engine oil
then add dye to that source, and run engine, and load up trans (A/T)
and see it leak and see the dye glow as it does with IR light .
$15 kit, to do.

try top post next time, what engine you have, and what trans.
we cant guess any of that, a swift to me , is a metal cage.
what matters here, is what driveline you have (cage gone)

05 malibu leaking oil from rear of engine

This may be from excessive pressure in the sump from blow-by from the compression process . It is from a blocked PCV valve that is not equalising that pressure. I have also known oil leaks to happen because the rear main bearing cap is leaking oil past the join around the bolts (loose) or no sealing compound used in assembling the rear main bearing.. I would look at the PCV valve as it is the cheapest test first.. Check that the oil is not coming from the front gear box seal or torque converter seal.

can be many ways.
get it clean and find it
or use UV dye kit and find it.

Valve cover gasket.
some versions (engines) have a Dizzy, it can leak.
no engine option stated? so can not be specific.
there are not that many gaskets in a water cooled engine, for oil.
3 or 4 seals, crank and cams.
pan gasket
valve cover gaskets love to leak because it is ignored.
and some 0-rings on some engines.
ive seen heads replaces and the mech didnt read the sealant steps
in the FSM for cam caps. etc.
do you have and A/T or M/T transmission?????????????
the A/T leaks, red ATF fluid, is it red?
the M/T can leak 90w, gear oil, is it very think and stinky"
the engine oil will match the dip stick oil, at tip does it?
and smell the same, (smell, look, and feel) use all 3 to discover
what it is.

why not ask any mech to find it, he can fast.
or learn to ID the oil type first.
and learn how to find leaks, (look)

Doesn't it seem odd to you, that two mechanics can't seem to get
involved enough to try and at least sound like they know the business
their in?

You didn't say what leaks,where it is,how,when,etc

Did they say the leak is fixable?

The EGR Valve,hoses & such, would be a good place to start

Why didn't they do that?

All this talk & no attempt to resolve a thing

We get thousands of people a week on this site alone,
what is going on with these shops,any idea?

My 2004 Kia Optima is using tons of oil! About 2 quarts a week. A mechanic did a synthetic oil change and in two months since, I have added 11 quarts of oil!! There is no leak and the engine is clean? How...

At this age of car(assuming average mileage)you should not be using synthetic low viscosity oil.
a semi synthetic 10/40 is factory recommended for cars over 60k.(far east/china handbook) i know that many mechs will tell you otherwise but it will NOT cause ANY these cars are on sale in china and use 20/50 as standard.(they dont sell any other type for kia/hyundai).this WILL slow down the oil bypassing the rings and burning.supercars that are HANDBUILT/plasma coated bores, obviously NEED super oils but the average car?........

Oil from spewing from front of engine for a few miles then stops.

take your truck to a mechanic with a smoke machine. He can add the dye and send smoke through the engine if there is a keak the smoke will exit the engine that is were the leak is the dye will tell the mech. the very spot the oil is comming from

4th starter in 1 1/2 years on a 2002 sable

Ask the mech to dissassemble an old starter if it is not turned in for a core. If it is an oil leak are you using a lot of oil to keep it up to the full mark on dipstick. The copper windings in the starter may be soaked with oil, and the oil will attract road grime and dirt and be so clogged that the brushes cannot contack windings and clog up the whole works. Check to see if the valve cover gaskets are leaking down onto starter, they may have vibrated a little loose and just need tightened or replaced. Can really be the only thing that would go wrong with the starter, unless your battery is way to small or way to big. Check CCA, Cold cranking amps with the owners manual for replacement battery size.
