Injector problem?

Hi All,

Another new member here.

I've got a 1987 90 CSW with the venerable 'td' engine @ 144,000 miles. I'd appreciate some advice on this;
When starting either from cold or if it has been run and turned off for an hour or so I get a regular puff of white smoke from the exhaust - coming from probably just one of the 4 cylinders - along with a little knock from the engine at the same time. If I leave it idling it will puff away for ages - longest I've left it so far is about 20 minutes.

However, once I've driven it for a short distance there is no smoke at all at idle. From reading this forum and others I think this could mean one of the injectors is knackered??
If so, is it worthwhile replacing all 4 in one go?

Cheers in advance.
Steve

hi Steve

i have exactly the same problem that you had with the regular puff of white smoke out of the exhaust, did the new injectors solve the problem?

thanks

I'd replace all 4 in one go as the recon aren't that dear in fact I think I've got eight spare ones some where in me cave!

As an alternative, bring / send the 4 injectors to me and I will check the lift and leak-off pressures on my Hartridge thing and set them perfect.

makes a big difference if they are wrong.

As an afterthought, I suggest you take out the glowplugs and replace them with best quality ones.

The puff of white-ish smoke could well be unburned vaporised fuel from one (or more?) cylinders that don't fire up quickly because the glow plug is duff.

The TD engine really REALLY depends on a good glow to light her up on a cold morning, and so while you may be "getting away with it" now in the summer, first chilly morning and you may end up with a Bat Flattery and more time at home than you planned.

He's obviously a slow worker then.

Doh, looks like this is on the list too.
