---1600 TD TIMING----HELP NEEDED!!!!!!

[CaliHarry25]

Hi All,
Seems the only time I do this is for help when something has gone wrong and its gone wrong!!

Just put my engine back in today after having some work done to the engine bay, when the engine was out i thought it would be a good idea to change the timing belt and tensioner.

I did this as the book, using the correct tools to lock the fuel injector pump and the bar to lock the cam blah blah!!!

So engine in and ancillaries connected and ready to try, so this is what happened.

Turned key, left the glow plug light to go out and also had the cold starter pulled out but wasn't havin any of it!!

Several more attempts to start and the engine run but seemed very noicey (more than usual) would not idle and loads of smoke from the exhaust!!

Is there any way of checking the timing and adjusting it with the engine in?

All help and advice it greatly appreciated!!
Also does anyone know a veedub mechanic in Northamptonshire just incase i can't do it? cheers

It can be checked with the engine, but you may have to remove the muffler to be able to access the crank bolt. If you don't have the tools to check the pump timing ,and have moved the pump ,there are marks at the edge of the pump face and a corresponding mark on the pump bracket. They are not too obvious, but they should be there. Line up the marks and it will be close enough to start the engine. If you didn't move the pump, then your belt timing is not right. If you are a novice at it, sometimes it takes a couple of tries to get it right.Be patient and have another look. If it was running before and not too much was done to it, it should fire up. The other possibility is if you removed the pump or fuel lines, they may have to be bled. Loosen each line at the injectors, and crank until a bit of fuel starts to come out, tighten each as the fuel comes out until all 4 are done, Re-light the glow plugs and try.

so if I align the flywheel to its tdc mark on bellhousing, lock off cam shaft etc. Is it ok then to slacken t belt tensioner and cam shaft pulley and move the fuel pump pulley until the marks on it align up if not already aligned?
thanks Caveman I'll have another go 2mw using your advice. 2mw's another day as they say and hopefully it'll make more sense

[caveman]

You don't have to slacken the tensioner unless the belt has to be moved again. Since it ran as is before ,i would double check the belt timing first. i always check the pump timing after i change belts, but in theory it should stay close.

woh woh woh ther dude.... if you have had the engine apart the first thing I would suggest you do is give it a chance... air + diesels don't really work.



* ensure the pump is timed up - it's in the book and involves a DTI gauge
* Remove the fuel inlet to the fuel pump and fill it with diesel
* (with help or a hot wired starter into engine bay) turn engine over and crack each fuel line at the injector to bleed the fuel lines
* if need be then use a little bradex/easy start to spin the engine up and help the starter along

Once disassembled diesels can be a reet pig to get settled/going again..

thanks Doug, Caveman. I'm gonna have another go tis mornin usin ur advise and fingers crossed i'll sort it!!!
will keep you posted!

where abouts are you owduck,there may be someone in the know just around the corner

Hi oldiguana, i'm in Daventry Northamptonshire.

Right been back at it tis mornin and checked fuel is getting to the injectors and ensuring no air in them - all ok.

in the process of checking the timing again now, got it all exposed to check ie cylinder head cover off all covers over timing belt off and the inspection cover off bellhousing. I now can't seem to find any mark on the flywheel to align with the arrow on bellhousing??

Also turned it over so cylinder 1 which is the cylinder nearest the timing belt is a tdc, well assuming it is as the valve followers are both closed fully to the top.

And the cam shaft locking plate aligns up at the back.

The fuel pump is in the correct position as the locking pin is in and the mark on pulley and bracket align up.

Is there any way of telling if the bottom end is at tdc? well should say piston 1 is tdc without going by the mark on flywheel or the relationship of the valve followers?

I ask this as when the engine was out i took the clutch and flywheel off so as it would fit onto the engine stand, i carried out the work to the timing etc then took it off the stand to refit the flywheel and clutch.

Is it possible that i have not fitted the flywheel in the correct place cos if so even if i do find the mark on the flywheel and align it up with pointer i cannot be 100% sure that it will be in the corrct position in relation to cylinder 1 tdc.

I hope this is making sense lol

[CaliHarry25]

Well still no joy!!!!

Rechecked the timing and have set as i believe is right but obviously isn't as its running a litle bit better but not quite there, noisy as hell and real smokey.

I think I'm gonna have to take it somewhere to someone who can sort it. Any ideas where I can go please???

[CaliHarry25]

Its back on the road!!!

Timing sorted, finally manged to do it and it feels soooo gooood!!!!!

I must say that my van is runnung better than it ever has, no smoke when engine under load and just seems to puuurrr if you can call it that lol.

Just like to point out that ensuring all the intake pipes, pressure release valve, turbo etc are in good condition and are not full of oil and collapsing goes a long way and helps good running of these engines.

I'd like to thank all that have given me advice, thank you

Just read this - what was the problem? Was it the timing? It sounds like the same problem i had when the timing was out...

Ringo

[CaliHarry25]

Hi Ringo,

yep timing was out after i changed the timing belt and tensioner. I had the engine out as I was having the engine bay resprayed and a bit of patching up done. Thought i would do it as it seemed the right thing to do at the time also degreased and cleaned the engine, replaced all the perished hoses and the pressure release valve off the rocker cover and gave it a service. oh and replaced the vaccum pump!

Unfortunelty i didn't get the timing correct first, or second, or third lol but managed to get the fourth or was it the fifth time? Anyhow all sorted now and I'm so blinkin happy to have her back!!!!!! Been out for a jolly tonight just for the sake of it, well actually I'm into Moto Gp and I'm off to Assen in Holland at the end of June so I'm gonna make sure all is A1 before i go. My twin brother and a mate are coming and unless she performs perfectly I'll never live it down.

Saying that she got me to Bruno in the Czech Rep and back last Aug (2000 mile trip) so I'm sure she'll do me proud.

Hi CalHarry,

I've just read you're heading to Assen?

Got any room for another? I've just decided to go myself. I know it's a bit late but looking to join up with others to share the costs etc.
