Angry Fault code, p340 p0016 valves changed, timing problem

57 plate Fiat Grande Punto 1.4 T-jet
I now understand where fiat gets its 'Fix-it-again-tomorrow' label from!

Basically, the car has experienced on going problems, since the turbo went in
April, 2014.
This was the most recent problem i had:
"https://www.fiatforum.com/grande-punto/441009-power-loss-blue-smoke.html"

Following on from that, the car continued to puff out blue smoke, give minimal boost power, drived slow, would sometimes feel as if it wasn't getting the right compression and then sometimes would!

Recently in June the car broke down three times in two days, misfiring + cylinder 1's spark plug on day 1 of breaking down was clogged with oil and fuel (According to RAC), and on the second day after putting in a new spark plug and changing the coil pack it clogged up once again, with cylinder 3 also clogging up now.

I should also add that (When it broke down in june) i was at the car wash, and the temperature of the car suddenly rose to the top and i was greeted with "Stop, turn off engine" message, when looking under the bonnet the engine coolant level was way higher than usual, and when i tried to undo the tank lid it 'spurted' out indicating pressure build up.

Now (september) the cylinder head has been skinned, new valves put in, and the timing has been reset. When on first attempt of 'completing' the timing fault code p340 was appearing, and then once changed again and clearing previous codes all codes went and then after being left to run for a bit p0016 appeared, with the car temperature rising. Also, upon start up the car sounds Rough (like a diesel).

++ Repairs have not been done at an official fiat dealership, No official timing tool was used in the process++
Any suggestions would be much appreciated as this car is soon going to be shipped off to scrapyard at this rate.

Re: Fault code, p340 p0016 valves changed, timing problem

I'm afraid the timing belt job has been wrongly done and it's probably too late to fix it easily. The diesel noise comes more likely from valve colliding with pistons. Nowaday's engines are real pieces of art and there are good reasons why manufacturers have developped specific tooling, ignoring them could easily lead to catastrophic results; sounds to me that's what happend so before blaming the car, go back to the 'non official dealership' to determine what went wrong ...

BRs, Bernie

Hi Bernie, I completely understand your point and believe that it's the honest truth, 'the mechanics' are more old school in trade and cars have came a long way since the 60,70s when they were mainly in the trade. My friend has a fiat timing kit which I will pass onto them and see if it help.
