I changed the timing chain and tensioner in a 1.6hdi diesel, so twin camshafts has a timing chain and tensioner connecting them. The chain didn't break rather it slipped 5 notches. The repair seemed to go well. I put other parts back together. The engine starts well but I get thick white smoke coming from it seems everywhere including the exhaust.
The injectors are leaking like crazy not just a small leak but pouring diesel.
I drain the "oil" and it turns out there's about 2 litres of diesel in the oil.
This is from running the van for maybe 2 mins max. So it seems an extreme amount of fuel is getting into the engine.
Can you diagnose. Here's a few ideas.
Damaged or blocked injectors(s)
Valve damage from when the engine was run with a slipped chain
Air leak somewhere possibly inlet manifold seals.
Injectors seals leaking.
Bad sensor like camshaft sensor.
I'm getting what I assume is a lot of blow by in the engine, a lot of gas build up and coughing, spluttering noises, and almost a runaway situation when shutting the engine off.
Maybe I just need to seal the injectors better, cut the seats better and secure it down tighter.
