White smoke from exhaust after changing timing chain

[Slick8]

I changed the timing chain on a 1.6hdi engine. I put it all back together, now I get a lot of thick white smoke from exhaust. The fuel leak off pipes are pouring with diesel. This tells me the injectors are over fueling. This could be caused by dirty/clogged injectors however I haven't really set the camshaft sensor very accurately I don't think.

Would a badly spaced camshaft sensor cause this over fueling or is the most likely issue dirty injectors, ofc maybe it's some other issue, crankshaft sensor etc, the crankshaft sensor may be slight off as it's missing it's top screw but I've tried to position it correct.

Any help would be appreciated .

Do you mean the timing chain (i.e. between the cams) or the timing belt? Have you had the injectors out? When you say leak offs pouring do you mean physically leaking or just high flow rates when tested? If they won't broken before, then unlikely all 4 have gone south. Cam sensor only used at start up to check up that cam and crank are in synch.

Yes timing chain between cams. Yes leak offs physically leaking, like huge spurt of diesel from most of them.

Does this mean the fuel pressure is too high. I did prime the fuel quite a bit I have to say, maybe I flooded the engine?

Other possibilities are clogged injectors.

Should I just let it run and see if the white smoke burns off?

What was it like before you worked on it? Did it blow the leak offs off? Pressure is controlled by the injection pump, unlikely it's too high. My guess would be the timing is out on the chain driven cam.

It was working fine before chain was replaced, marks on chain were matched with marks on camshaft sprockets. I'm think displaced cam lobes or damaged valves. Reason chain was replaced as it slipped 5 teeth during timing belt change and the garage ran the engine like this but rockers, cams looked fine on visual. They assured me no damaged but wouldn't fix the problem so I took it home to fix myself. They would only take cam carrier off for me to see.

Let it run on idle for an hour, see what happens, if still blowing white smoke then investigate. Don't rev the engine, just let it idle. If there is any issues it will present itself. Just put your hand near and around the engine to spot any oil/air leaks.

I feel it's at the dangerous stage though, diesel leaks, potential oil leaks, potential gas build up.
