Avensis diesel engine ''worn out''

chillin117

My 03 Avensis D engine has over 400k on the clock and still runs great but burns a bit of oil so would not pass emissions test at NCT in 3 months. My mechanic says it's just worn out and would need a rebore with oversize (020) pistons/rings etc. Probably get the crankshaft done too and replace the big end and main bearings while I am at it.
Would I be better off just getting a replacement engine (that I know nothing about) or getting my own engine reconditioned with Howards or someone ?
The rest of the car is in excellent nick.
Thanks.

A replacement engine will cost you around €600 for that car. Factor I n fitting after that so you'd be looking around €1000+ for a transplant. Lotta money on a car of that age/mileage. Can't see overhauling your current engine being a whole lot cheaper. Has it maybe reached the end of its life???

Not DIY effort, moved to main forum.

You say it's an avensis d? Presume you mean diesel?

If so: there is no emissions test, only a test for smoke - in which case unless it's blowing serious fog out of the exhaust I can't see you having too much trouble once you give it a thorough blow out on the way to the test.

400k on a toyota diesel is not high mileage

Think u are right

An Italian tune up, and a lash of dipetane.

Run it hard , and use dipetane for two weeks.

Then nct it.

See what happens.

Nct it early..

That or sell it before the nct expires.

See about running a thicker oil it should help reduce the oil burning and help lubricate the worn engine, an 03 d4d is a pretty robust engine so it should tolerate it.
Also unless it's woeful bad it'll pass the nct smoke test

Edit did ye check the condition of the turbo and it's seals that'd be the first place to look on a high milage diesel

Special Circumstances

Drive it on! Diesel is so good for people and the environment that they don't even test it for emissions!

Special Circumstances

Any thoughts on adding TCW3 (marine,ashless) two stroke to older diesels?
Or would dipetane be the way to go here?

Be grand for idi engines,

But not sure if the 2 stroke would benefit the d4d or not, I'd imagine the injectors would be a bit more picky than the older ones - whether a drop of 2 stroke would affect them or not I'm not sure as I have no concept of modern stuff


You could put a sod of turf in an idi engine and it would probably burn it, I had a 1kz powered surf and there was nothing it wouldn't run on.

all d4d from that era like their drop of oil, we have a 06 model with 300k km

one thing my mechanic says is NOT to use a heavier oil

I am not familiar at all with the Avensis but i have had a few other diesels.
Have you considered cleaning the intake manifold and the EGR valve? Has this even been done before on the car?
Then run it with a bit of Dipethane for a while before taking it into the NCT.

Relatively small cost especially if you can manage it yourself or with a friend.

If it fails then you can weigh up the options.

That'd be the norm for most modernish diesel anything above 10w 40 isn't really recommended 5w 30 being the norm however if a car is drinking oil and it's not being lost through the turbo seals then a thicker viscosity oil can help(d4d's wouldn't be as delicate or refined as other diesel engines of that era). I think toyota began recommending a higher viscosity oil for defective 1zzfe 1.8 petrol engines while they were getting round to replacing them under recall.

Why do people keep saying this around here? Smoke is not some magical fairy dust - it's an emission.

Is it a very stringent test?

OK so, show me the co & lambda results from the diesel test then?

It's a smoke test, call it what you like but that's what it is...

The NCT manual doesn't state exactly what size particulates are measured, so it's hard to tell.

Diesels traditionally didn't have lambda sensors so it wasn't relevant until recently. I'm not saying the NCT testing of diesels isn't flawed or is comprehensive in any way, but to say a smoke test is not a test of emissions is false.

For the purpose of being pedantic you are absolutely correct, for the purpose of keeping things in simple terms to answer the op- he need not worry about the levels of burnt oil in his emissions, provided the ppm levels of smoke are below the nct requirements, which I suspect they will be provided he roasts the arse off it on the way to the test..

Yes, that's true - won't really know if it will pass until he actually tries the test, unless it's visibly very smokey. I'm not sure if Dipetane would really help in this situation: I tried with and without the stuff various times when getting my Peugeot 406 tested and results were inconsistent either way (oil consumption was about 1 litre per 6000 miles so maybe not relevant to OP's problem).

It does not really smoke only a very small bit but she's ''Atin'' a litre of oil a month

How much mileage is done in a given month?

It's not a great unit of measure, some folk can do a good few thousand and some can do a small few hundred miles/kms..

I bought her as a 3 yr old with 160k on the clock so 240k in 10 years is 24k a year which is 2k per month, 500 miles a week ( still use the old money!):D

Agreed.. if the car emits it then its an emission of the car

Nct emission test for petrol cars: CO/HC/Lambda

Nct emissions test for diesel cars: smoke

Simply put, it's a smoke test. Why give an ambiguous answer when a clear one can be given?

Then you should've given a clear answer

The smoke or fumes are emitted from the car so it's an emission of the vehicle

The emission test on both types of vehicle look for different things

I am glad this Keyboard Tennis has reached a conclusion. I have seen some good (long) battles on Boards. One or both are usually banned and they are quite entertaining to the casual spectator .

lol was only messing ye around

If that constitutes trolling then my apologies

Are you sure the engine is actually burning the oil? could be a seal in the turbo on the way out and blowing a small amount of oil out the exhaust. That would account for failing the smoke test also
