Nice one!
Thank you. I will see how mine look.
Thank you. I will see how mine look.
I agree with you to be honest (about the snake oil additives) but desperate times mean desperate measures. I have even looked at the price of low-mileage engines from scrapyards today, but you don't know what you're buying plus I really would be out of my comfort zone swapping an engine on the drive. I know my son's done it with a rear wheel drive car and 3 big mates and a crane, but he's not here nowadays!
*If it comes to the stage of swapping engine's.
iwill lend a hand, just give us a shout if needed,
Thanks for that. I really appreciate it.
I am going to do a compression test asap (hopefully by Thursday night) so I'll let you know how I get on with that.
I have also got some Forte flush stuff but I won't use that until after I have done the compression test (or maybe not at all).
It says it neutralises harmful deposits and revitalises your system, so if I don't put it in the Punto I might drink it . I could do with my system revitalising!
Compression test is your best bet,
My guess is on Valve's,

I have not had chance to do the compression test yet but I have got the tester here ready to go. Should have it done as soon as I can get my hands on the car for a couple of hours.
I came across some pictures I took when I changed the timing belt and water pump last year, so I have attached the 2 pictures of the lower pulley - one when it was timed correctly, and one when it was timed incorrectly by a garage (taken last week).
It might be useful as a reference for somebody to show that just one tooth out doesn't look much but made a hell of a difference to the performance.

Sorry- no idea why the correct photo turned itself round by 90 degrees.
Hopefully that doesn't confuse people even more!

interesting, only 1 tooth out and causing all these problems
What do I have to disconnect to stop the fuel being fired in when I am doing the compression test?

crank sensor i think
I think the one tooth out was only causing the lack of performance.
I think the oil burning has been caused by something else, but I will know better when I have done the compression test.
I'll let you know what the results are when I've done it.
One tooth is over 15 degrees on that crank. If you look up typical valve opening and closing positions 15 degrees is a lot.
Well I took the plugs out (see pics). Number 4 was much oilier than the other 3.
I then took the compression readings - well I did of 1, 2 and 4. Number 3 to be honest I could not get the compression tester to seat properly so when I tried the test it just popped, so not wanting to bug*er up the thread I chickened out and abandoned that one, as number 4 seems to be the oily culprit.
I m not sure if it is good or not in this instance, but each of the 3 compressions I took all came out surprisingly equal, about 16.6 to 17 bar.
That was higher than I was expecting.
I put all the plugs back in and started up and gave it a boot full and there is definitely some oily smoke around. In terms of consumption it has used about 1/3rd of a litre in about 100 miles. So clearly something is wrong.
There is a small drip of oil coming from somewhere just above the oil filter (but not the cam cover), and Iam not sure if the breather pipe to the air box had come adrift, as it was not connected when I lifted it up, but it may have just come off as I lifted it, not sure.
One thing I did notice was when I opened the throttle butterfly there seemed to be quite a bit of oil in the bottom, which I have never noticed before and is maybe a clue?
So, what to do next? The forte engine flush?
Any suggestions happily received !!

could've been useful for a wet/dry comparison,
just a dash of oil down each plug hole,
= IF the figure improved markedly on 1 bore , then it points to bore wear / leaky ring(s)
but if the 3 x bores you measured were that close.. you should be o.k.

I was going to do a wet test as well if one of the compressions was much lower than the others but it wasn't the case.
So, what to try next?

After more googling today I came across this thread from some time ago which seems to mirror our situation in that the oil smoke started shortly after the HG change and turned out to be down to gunked up oil control rings.

Mine isn't smoking anything like as bad as his was so I am thinking I might try the Forte flush idea first and then see what happens. Any thoughts on that logic?

Well the smokiness continues, and the tail pipe is black. Oil consumption is till above what it should be, so as a last resort before anything more drastic I am going to try the forte engine flush treatment. Judging by the state of the spark plug on cylinder 4 I am fairly confident that if it is a stuck oil ring, then it is on that piston.
The instructions for the oil flush are to warm the car up, then pour the bottle of fluid in to the oil filler and run it for 20 minutes or so (depending on how neglected the car has been (longer if very neglected, etc) then drain it out. And re-fill with fresh oil.
I was wondering if it it is worth pouring a spoonful down the spark plug hole just on number 4 the night before to give it chance to really have a go at that piston?
Any thoughts on that or should I just do as it says on the bottle?
