I my have been lucky when I replaced the timing chain. I simply followed the procedures and tried to understand why it was so. It may have been the fact it was running before I started if although a little smokey.
The leap of faith was a big one when you have to rebuild the whole front end before finally turning the key and hope the whole thing doesn't self distruct. It didn't thankfully and the only further adjustment necessary was to tweak the pump position that I had previously centred on its adjustment.
Its still smokey on acceleration, more so when cold but very acceptable for a 50 year old engine.

I will follow your example and go with care and slowly.

Dear all I am back. Had a few family problems but back to my smokey engine. To recap I have replaced the injectors, the timing chain, reset the timing as per the green book, moved the pump in every position but still lots of grey smoke. So I sent the injector pump off for testing.....it came back confirmed as working as it should. So now what.?...I guess I need to get a compression tester and give that a go before taking the head off.
Does anybody know what the pressure should be? Also all the pressure testers come with threaded connectors so I assume I have to use the glow plug holes, does anybody know what thread it is?

Many thanks

Bob

Have you confirmed the camshaft timing is as it should be?

Hi, yes exactly as the green book.

Best wishes

I'd be whipping the manifolds off and having a look at the valve stems. If the cam and ignition timings are spot on then it could be your smoke is coming from leaky stem seals. My engine smokes like hell when cold but it clears once its hot.

Also make sure the butterfly valve on the intake is opening just before your accelerator pedal opens up the pump.
I had a play with an annoying fuel leak today and when I bled the system and fired him up the drive disappeared in a cloud of smoke.
A tweak of the valve sorted it. Valve clearances tomorrow as I aint checked them in two years.

Thanks guys. I am buying myself a compression tester and the head is coming off. I checked the valve clearance and the butterfly valve last month and all ok. It feels like one piston has lower compression than the others, having said that it starts without using the glow plugs.

Thanks
