basically my car smokes either when i have accelerated hard and when i slow down or when ive say been goin down a hill in 3rd or 4th and when i need to accelerate pours out smoke then. its dark blue/black smoke. I think its my pistons/piston rings as i have had most of the top engine fixed. my car has only done 63,000 miles. any suggestions on what the problem could be?

Ur car is burning oil - as to where from - I believe it to be from worn piston rings if the head was done properly. Now as for the rings - if they need changing, its gonna be a fair bit of work. U did not say which sedici it is - 1.8 or 2.0?

the sedi is the 2.0 the 1.8 is called a granturismo

my car is the 2litre. any idea how much piston rings are? and where to get them or is it best taking it to a specialist? the nearest specialist to me is L and M who have done all the previous work before

its really depends on how mch mechanical knoledge you have and how dirty you want to get lol. Piston rings can be a pain in the butt at the best of times, if you dont have mch knoledge best to leave it to the experts. now if i remeber rightly i seen a set of pistons with rings for a tipo on ebay recently i'll see if i can find the auction again

yeah ive seen the on ebay but i dunno whether be worth going for a brand new set? i will prob leave it to the experts to change as i wouldnt have a clue where to start.lol

Hmm since when - not. Maybe in UK I dont know what they called them, but in Europe a sedicivalvole Mk I was 1.8 16v, sedicivalvole Mk II was 2.0 16v.
Now on to more important things...

mk1 5-door 2.0 16v was a Sedicivalvole, as was the mk2 3-door 2.0 16v

Have you had the cylinders compression checked?

There is two main reasons burning oil 1. screwed valve stem seals and 2. screwed piston rings. if you have had the stem seals done with the work done to head then it will prob be the piston rings and if so at 63,000 miles your engine has had a hard life. You can fit piston ring quite easy but you must be careful not to snap the new rings as they are made from very brittle metal and don't flex much. You would have to remove the cylinder head and sump then undo the con-rod bolts then push the piston out the top, you can pick the old rings out with 2 small screwdrivers but don't score the piston surface. when fitting the new ring just place the ring on the top of the piston and pull it gently open till it can slip down and over towards the grooves for the rings, start with oil scrapper ring then the two compression rings. When fitting the piston back in make sure that the con rod number stamped on the bottom of the rod is facing the rear of the engine as the piston's gudgeon has a 1mm offset towards the rear off the engine. You will prob need a special tool for inserting the pistons back into the block but can be done without if your gentle enough with feeler gauge or small screwdriver. Once all in you can build up the engine and do the timing, you can do a compression test and all cylinder should be about the same, if your down on 1 or 2 cylinder something else might be wrong but should be fine since you had the head done. You will have to run the rings in so no hard throttle till completely ran in

thanks for the info guys. I bought the car a year ago with no sevice history (probbably not the smartest descision) because it had been in storage at a garage for years because the previous owner died. i had a comprssion check before i had the head done and it was all perfect except one but now all that is running smoothly sounds like pistons then. guess my nice new suspension will just have to wait a while longer.

No in Europe mk 1 sedici was 1.8 ltr or 2.0, they never bought that 1.8 version to the uk.

Correct! 1.8 16v was the first and the best sedici engine also. Here u can see what that engine can do when turbocharged for instance:
