Hi -
Having a few issues with a newly purchased remanufactured 2.5NA stripped Diesel engine. Any suggestions welcome!
Following engine failure, I ordered a new (remanufactured) engine (stripped (sump to rockers), along with 4 injectors and a fuel injection pump, and set timing belt) from McDonald Land Rover Engines in oswentry. Collect it last week. While the service offered was quick and friendly, I'm disappointed by the engine finish - a few bolts on the flywheel housing missing, a missing starter bolt etc. I put the engine in the 110 today. I was unable to start it while stationary as I was having difficulty priming the fuel lines. A tow start did the job. It initially started which huge clouds of white smoke - presumably water in the exhuast etc (car stored in a humid-ish garage for 2 weeks stationary while swapping the engines).
It ran relatively well at tick over at a stand still, puffing white smoke for about 10 min. Later in the day, i took it for a drive. Covered 30 miles. Throughout the drive, and now at a standstill also, it billows black smoke. Not particularly thick, and cetainly not blue, but much more than i'd expect from an very worn or badly timed engine, let a long a brand new one. Along with the smoke, there seems to be an excessive metallic noise coming from the engine, which to my ear sounds like excessive tappet noise. Is this usual for a brand new engine? It also seems to lack power. at 35-40mph in 4th, i'm unable to accelerate further in any meaningful way.
Called McDonald who suggested checking the tappets and injectors. I checked the tappets this evening. Some are a little loose (no drag at all on the feeler blade (0.01 inch), others are a little stiff, (feeler blade needs to be wiggled and pushed in to fit). That is, they're not all the same, but i'm unsure if they're sufficiently off to be causing the (a) problem. I haven't yet swapped the injectors.
What could cause such problems if not the above? Could it have been badly timed? I understand black smoke is ofter badly burning or badly delivered fuel?
Any comments or suggestions welcome.
Thanks,
Martin.
 
hi martin
the loud metallic noise could be a faulty injector, i had it in my series 3 diesel , both engines share the same injector. You can check by raising the tickover rpm bit faster so it does not stall, and still clatters
then loosen each fuel pipe in turn at the injector and hopefully the noise will stop, when i found the dodgy one this was removed and reconnected to pump to see the spray pattern when turning engine over (loosen other pipes to stop engin starting beforehand) the faulty one on mine was a solid jet of fuel rather than a mist. you might get away with removing end and cleaning nozzle.
 
The noticable lack of power, or "it doesn't feel to go any quicker when it gets to so many revs" is just the way that the 2.5 N/A is unfortunately. It's a really really good solid engine, and a recon should last another 60 years or so! If it were a 2.5 Turbo (19J, as oposed to your 12J) it would go that little bit quicker on high revs, but the N/A is just a little slow that's all! I've got used to mine.

It shouldn't be producing loads of black smoke and making matallic noises tho pos

Have you got any means of double checking the timing?
