Groliffe smoking like a forest fire - another question
Groliffe smoking like a forest fire - another question
Hi all
Groliffe smokes initially on start up, and then profusely and persistently when we are idling after a fast run on the motorway. Fuel consumption is poor.
This is what I think:
I may have put the timing belt back on one tooth out - there was a bit of fiddling. Would this be consistent with the smoking?
I think a glow-plus is out as it is lumpy as well as smokey on start-up. Does this make sense?
I suspect the injectors are knackered and need re-conditioning. Is there any way of checking this?
All thoughts welcome, as ever.

lumpy on start up and the smoke can be caused by a timing belt being a tooth out.
Lumpy running with a glow plug out is possible, but should clear very quickly as the cylinder comes on stream. You will get a puff of white exhaust smoke (unburnt diesel from the non-working cylinder) until it kicks in, then all should be as normal. My experience of 'starting on three' is that the fourth pot kicks in quite quickly and will run well after that. Of course, once the engine is hot, and you start from hot, you won't get the lumpy running if it is simply a knackered glowplug.

Thanks fellas.
Scarecrow it could be you if you fancy giving me a hand on Friday?
Messer, that's pretty much what's happening on starting - lumpy start and clearing up quickly.
Steve I didn't think of the pump bolts, I'll have a look.
The plan is this then: refit timing belt, check glowplugs, check injectors, refit steering pinion valve, in that order, over the next few weekends. SWMBO is going to be SO pissed off

I'll come, but really you want sdelesal (another Steve) he rescued my old estate from some very shoddy mechanical repairs that the garage I'd been using had failed to diagnose I have to say, I'm not best pleased by what I've been told, both with regard to the original vendor and the specialist repair centre.... That's life I suppose. I'm more discerning now about who does what repairs and I make sure I get a receipt!
Regarding the above, it's time we updated the list of repair specialists recommended by the BXClub... Some don't even exist any more, per se.
Oscar, have you got a diesel manual there? I've got an untouched Haynes manual here which I'll bring if you like...

There will be a copper washer under the injector (it may come out with the injector or stay in the head) so long as that is present when putting them back in you should be fine.
The glow plugs rely on the thread to seal so nothing needed there. A bit of copper grease would help them to come out next time though.

Cheers, but where do I put the points of the multimeter? I'm not good on electrics yet.sdelasal wrote:For the glowplugs, you need only to measure resistance of each plug - they should all be about 1/2 to 1 Ohm each - no need to remove them just disconnect the wire. Steve
