White smoke 300tdi. Advice please

Marmaduke · Jan 30, 2016

Right some history....

Stuffed my own 300tdi engine and having a right ball ache rebuilding it so I decided to just swap it over, 1 engine out 1 engine in...

Hired a van and bought a replacement last weekend which I was told by the seller that the engine was a good runner with less than 80k on it.

Did the rear oil seal and put my fairly new delphi lift pump on it and a new timing belt and stuck the engine in. Starts it up ok but there's white smoke on tick over and clouds of white smoke and lumpy running on fast idle. Swapped the injectors for my old ones and still the same so swapped the injector pump for my old one and re did timing belt and it's still the same and now I'm stuck as to what to do next. I don't know anyone with a compression tester

Thoughts please as I need it back on the road ASAP and it's going to cost me £90 to hire a van to return it so I'd prefer to sort this one before I think about buying another one

Having swapped injectors and ip for known good ones it would deem this is not fuel - white smoke and lumpy - I fear head gasket................................ any oil in water or other way round? Is it actually useable? maybe try to put a few miles on it............................. good luck

Yeah sounds like water burning off.

Does it drive? head gasket is not a big balls he to sort just spannering

It's definitely unburnt diesel not coolant

Marmaduke · Jan 30, 2016

And there's no pressure on
coolant pipes and no blowing from the engine breather either

Well worth rechecking the pump timing, then recheck it again.
Have you popped the rocker off for a look see?

Mine did this when we first started it after rebuild. We re-did the timing .. the cams were 180 degrees out. Turn the crank 1/2, then the cam pulley 1/4

Does it look and sound like this?

wattfield · Jan 30, 2016

I've had a drink or two, mydinner's ready, so I'm not going to search for my old posts, so anyway... retime the pump, if that's a problem for any reason just advance it (turn it clockwise) a few degrees.Worked for me!

The thing I can't get my head around is the woodruff key is up and vertical, the timing mark lines up with the cam pulley and the fuel pump locking tool goes straight in its hole so I'm lost

I thought mine was timed accurately, try advancing a few degrees.

Which pulley?

IamRobbie · Jan 30, 2016

If I recall you arnt to far from me duck so if you need a compression tester give me a pm dude I brought a set brand new and haven't used it yet. There's a few good shouts yet that you could try but if you need one you can borrow it mate.

When he mentions timing it up and advancing it's using a smaller pin and trying to turn the pump clockwise which advances it slightly

The injector pump - slacken the bolts on the locking plate, turn the centre nut a few degrees clockwise & tighten the bolts back up

Thanks for the kind offer, I can't see how it can be the head gasket cos if it were leaking where's the pressure going? It's not chuffing from the breather and not pressurising the coolant pipes.
I'll try the timing tomorrow

Thanks for that I'll have a go tomorrow

You would be better using the correct timing pin in the bellhousing into the flywheel, whilst the woodruff key may look vertical it could still be a few degrees out.

The wading plug in my bellhousing is so chewed up I couldn't get it out. I followed advice from Diesel Bob, as per another post of mine recently.
