Engine issue (non-Omega) any ideas?

[cruisetopoland]

Hi folks; just bought a little runabout and thought someone might know what to do-I know its not an Omega but there are many clever fixers on here 

It is a 989cc Daihatsu engine, 3 cylinder 12v, double overhead cam, which was stinking of oil when it arrived.  Traced this to a split oil filter seal, did an oil and filter change and cleaned the mess off, now dry.

I have had three cars with the same engine, but this one is just not quite right:
Happy when cold, lazier when warm
Happiest on light throttle, bogs slightly on full throttle
Using a little oil
Black smoke on full throttle when standing
Very fumy, mildly eggy under demand
Slight smoke from hole where dip goes in, when hot and dipstick removed

I have checked the plugs, changed the oil, used posh fuel and treatment and then thrashed it to undo 27k of  OAP pootling, checked underside on ramp and exhaust is nearly new and leak free, air filter changed and box hoovered.  No oil in water, water in oil.

These engines are usually bomb-proof and do 150k without issue.  Ideas, anyone?

Much appreciated (especially as not Omega!)

cat or needs italian tune up

Agreed 

[tidla]

italian tune up= roll it down a mountain?

[cruisetopoland]

thanks guys 

It has just passed MOT last week, emissions fine then  :-?

Being electronic ignition, can't tune it.

Have thrashed the bejesus out of it trying to clear it out.

Drives ok, but not as this engine should.  COuld it be anything else?

Advice much appreciated

Sounds like it's running a little rich under load. Could it be a MAP/MAF sensor issue, coolant temperature sensor, etc?

I had a similar problem with a 3 cyl. corsa, ran fine when cold but did not want to work when warm / hot.
changed everything and cleaned everything. even had it on the computer at a garage with no result. eventualy I found the problem,
It was a streched timing chain. so I bought a timing chain kit, changed it and it ran like mad,
if yours has a timing chain it might be a good idea to get it checked out.

I would be thinking MAP/MAF.

I would also be doing a very major breather/throttle body service to.

From my (limited) experience of these lumps, they seem to wear quite quickly so could be a ring issue (seen a few like that at 80K ish miles)

Wooh, good point 

Belt is overdue due to age.  £22 delivered from main dealer or £90 fitted-fairly straightforward job.

Will add to "the list" (deja vu anyone?)

Good point-will check these

God, hope its not a ring issue at 27k  miles

Will do the overdue belt and a sensor check, plus give the throttle body etc a birthday 

Many thanks

i used to have a gtti [i think] back in the 80s was very quick and reved all the way.
havnt seen one for years
only time it felt sluggish was when i fitted a patten air filter.
dont know if you know but the also made a 3 cyl diesel,had one once from the dealer while he serviced my car,it was very.very slow.

Lol, I sorted out a 3cylinder turbo diesel one, the owner had gifted it to a friend because the garage said it was scrap with a knackered engine.

The main fault was the old sod who owned it did not beleave in servicing so a good flush and most importantly, a new air filter later and it was quite nippy.

Update:

Just had breathers and throttle body to bits.

Breather pipe wringing, intake saturated with oil.  On opening filler, there is oil lying there.

Also-the new oil (300 miles ago) is now black as tar

Eeek?

What to do?
