Sad days for the Cuore :'( - LadySteve - 19-07-2014
So the oil burning.
It wont make it through its mot with this current issue and its mot is due in september. That means I have just over a month to fix the oil burning issue. Ive asked my dad and hes said he doesnt mind us fixing it ourselves.
People have suggested it could be the piston rings etc. I asked for some advice today from a garage whove done us quite a few solids in the past. Theyve said it will either need a complete engine rebuild or just a new engine altogether....both of which are very pricey. I think the first plan of action is to take the engine apart and figure out just what the problem is, then we can decide what the best option is from there onwards. But firstly I need to decide whether to do this up north or down south. So are any of u guys willing or free to help on this? Ive got steve obvs but think we might need a bit of help.

This definitely is screaming out for an engine change...
RE: Sad days for the Cuore :'( - Jonny81191 - 19-07-2014
I'm sure if you make lots of bacon and tea I can drive over and throw abuse at Steve while pretending to help?
Course I'll help, do it down South
RE: Sad days for the Cuore :'( - Niall - 19-07-2014
I'll help down south....giggidy
Your garage is talking a bit of rubbish though. There is only 3 reasons for oil entering the bores:
Worn piston oil control rings
Leaking valve guide seals
Cracked head or block
The last would be the only one to need a new engine and I highly highly doubt it's that.
When does it smoke? If it's just after it's been idling then you get a puff on pull away, it's normally valve guides.
Tbh we could have this back together in a day. There is sod all to this kinder egg present engine
RE: Sad days for the Cuore :'( - Piggy - 19-07-2014
how much would a replacement unit cost?? Cant take long to swap motors?
Be quicker and simpler and possibly cheaper??
RE: Sad days for the Cuore :'( - Niall - 19-07-2014
James these have a reputation of burning oil I think so you may pick up a new engine only for the same thing to happen 100 miles down the road

It smokes mostly if I rev it while it not moving. Drops alot of oil out the back with no smoke if its left idleing for a while...hardly ever smokes while im actually driving

Haha sweet man thanks. Will probably call u up on that and can defo provide the refreshments for ur trouble

Yeh. On the one hand it would be easier and cheaper to just bang in a new engine...but as u say...might end up with exact same problem..or even something worse
RE: Sad days for the Cuore :'( - cully - 19-07-2014
get a dry leakage test done followed by a wet leakage test that will tell if its rings
then whip the plugs out and look at the state of the bores with a boreoscope
no point trying to doit all in a day with scored bores as it will need a rebore/pistons/rings
RE: Sad days for the Cuore :'( - Piggy - 19-07-2014
I know they have a rep for it...but most do just swap them out. Find one from a reputable source, low mileage car. May even get lucky with a unit with 6months guarantee
RE: Sad days for the Cuore :'( - lolsteve - 19-07-2014
No luck finding one, anyone think that another engine flush or two and running the car on diesel engine oil might help clear out the what are apparently gunked up piston rings? Since this what diahatsu drivers seem to be saying is the main source of the problem
RE: Sad days for the Cuore :'( - C.A.R. - 19-07-2014
The car surely isn't worth the money/effort?
I could understand if it was something desirable but it's like a peg down from a Nissan Micra? Just replace the car?!
RE: Sad days for the Cuore :'( - Poodle - 19-07-2014
Do it down here mate, we'll have it sorted in no time. Plan to spend two weeks, should be plenty of time to account for everything. We've got all the tools required short of a compression tester, and i want an excuse to buy one of those anyway lol.
RE: Sad days for the Cuore :'( - Martin306 - 19-07-2014
I say stem seals.
My 2.6 vectra b puffs oil when you rev it but it never seems to use much oil on the dipstick level. It definitely is stem seals on my car
RE: Sad days for the Cuore :'( - Dum-Dum - 20-07-2014
The Cuore has a rep for needing piston rings giving the symptoms you have so that would be a good guess.
It can technically be repaired with the engine still in the car but its far easier out and it is kinda a full rebuild job.
Personally I'd get a new lump off ebay (only £100) and strip it get the bores honed (niall and piggy both have hones IIRC) then fit new rings (about £80) and rebuild it with a new cam belt water pump and fluids (about £150 at a guess) also you can do the valve stem il seals while your at it, they are only a couple of quid each and theres only 12 of them.
Its probably 1 day to strip the engine, 1 day to rebuild it and then 1 day to fit it .
I am happy to help any day I'm off work if im fed and filled with the and cake.
RE: Sad days for the Cuore :'( - THE_Liam - 20-07-2014
I'm more than happy to help if I'm not working
Having seen the issue I'd say it's definitely rings. Stem seals/valve guides tend to let the oil into the cylinder overnight causing a smoky start, this is worse when its revved.
I'd still try pouring a strong solvent into the bores through the spark plug holes and leaving it a couple of days.
RE: Sad days for the Cuore :'( - toseland - 20-07-2014
Carb cleaner works a treat if you can get it in the non spray form, put the spark plug back in as well to retain the solvent in the bore for longer

I was thinking something like paraffin that would dilute and disperse the oil.
RE: Sad days for the Cuore :'( - lolsteve - 20-07-2014
We have lots of STP injector cleaner about (thanks fcs
) would that be near enough to try or will it not evaporate or whatever?
RE: Sad days for the Cuore :'( - Niall - 20-07-2014
Carb cleaner would be ideal. Like Toseland said, get it in there and put the plugs back in. Just do not start it like this! Leave it over night, whip the plugs out and turn it over a few times to get everything out of the bores then get the plugs back in.
That said, i think thats only going to be a temporary fix. The damage will already have been done and if its valve guide seals, doing above won't make a blind bit of difference.
RE: Sad days for the Cuore :'( - THE_Liam - 20-07-2014
I'm certain its the oil control rings to be honest, caked with nasty oil.

^this. We'll rip it apart in no time and then it'll be fairly obvious what the issue is, parts might take a few days to get hold of but as Alex says, allow 2 weeks and all should be fine
RE: Sad days for the Cuore :'( - Danny2009 - 20-07-2014
I have see a full one of these for £180
In Coventry I can post the link if it's any use
RE: Sad days for the Cuore :'( - jammapic - 20-07-2014
I agree with you Liam, no way it's valve stems... got to be rings that are the culprit here!

RE: Sad days for the Cuore :'( - lolsteve - 20-07-2014
Yea man can you post up a link ?
Reading up on freeing sticking piston rings people are suggesting using automatic transmission fluid and pouring that down the bores then leaving for a few days. thoughts?
If its the rings being dirty rather than broken what are the hopes that cleaning can bring it back
RE: Sad days for the Cuore :'( - Danny2009 - 20-07-2014
Can't seem to find it now :/
Quick eBay search fetches up this?

Wouldn't use ATF mate, that shit won't even burn in an XUD, you'd just be adding to the caked on mess. It needs a strong solvent to dilute and dissolve the caked-on oil. Even petrol would be better...
RE: Sad days for the Cuore :'( - Dum-Dum - 20-07-2014
Gotta say I dont think a cheap fix will last any length of time.
RE: Sad days for the Cuore :'( - pugmanxud - 20-07-2014
I'm well up for giving a hand! Also have a bore hone. A re ring and a set of stem seals will sort it out bear in mind it will need 500 to 1000 miles to bed the rings in to notice if its sorted it. Or you could take it to your local friendly lenient MOT man.
The oil additive stop smoke really does work. Used it on all sorts. Google liquid rebuild
RE: Sad days for the Cuore :'( - Danny2009 - 20-07-2014
Xud's do burn ATF fluid
I'd just keep topping oil up and get a new lump

have to agree with him. Poor a shit load of petrol down there and it will just dilute the oil and not do the bores any good.
There is only one repair for this and its to have the thing in pieces and replace the rings and/or stem seals.
