My Defender, a 2010 Puma 2.4 model with 42,000 miles, has been broken down for several months.
My problem started suddenly with the appearance of blue smoke from the exhaust.
On the advice of others, I decided to replace the injector seals and the rocker cover seals. Unpleasant surprise on dismantling, the exhaust camshaft came loose (as shown on the picture), and a rocker arm (cyl4) fell into the cylinder head causing quite a bit of damage.
I decided to dismantle the cylinder head to replace it, but on dismantling the cylinder wall (cyl3) showed a strange mark.
The decision was made to replace the engine with a second-hand one, so we put it back together, started it up, coded the injectors and learned how to inject.
A short test drive, 5 miles and the Defender starts smoking again.
I've tried again since then, and it smokes even when the engine is cold.
The problem persists despite having done :
2x turbocharger
Injector seals
Test injectors -> one had a low flow so I replaced all 4 with new ones (original)
Glow plugs + intake pipe cleaning
Compression test ok
Clean sensors, MAP & MAF (also smokes with flow meter disconnected)
No fault found on diagnosis. I'm completely lost, is the smoke coming from a problem on the new engine... or from a component that hasn't been replaced...?
Thank you in advance for your help
