2.5 N/A symptoms

fit 200 tdi

Nice job, how did you find it? Running in will take about 500 miles of hard work or there abouts, but it should stop burning oil after a couple of hundred.

Next step is to clean the surfaces of all the pistons, are there any cracks or splits? If there are replace them with brand new ones, available from Paddock Spares - Land Rover, Range Rover Parts & Accessories - Discovery, Defender and Freelander If you can afford to replace all four then go with it. Remember that the crowns do come with rings, but you will need to use your existing con rod and gudgeon pins (the bit that holds the piston crown to the con rod.

That bearing is definitely knackered, so replace all bearings!

Well my plan is, new rings and new bearings, the pistons have no cracks or spilts so they seem fine.

Good stuff, this is going to work out as a very economical rebuild then. As far as I can remember, a full bearing kit was about £9 and the rings weren't quite as much. It will pay you to buy an extra set of rings too, I snapped about two when it came to fitting mine; just be gentle with your piston ring pliers! Also take care when lowering the pistons back into the bores. You'll need a piston ring compressor tool (about £10) to stop them catching on the top of be block as you lower the pistons back into the bores. Also make sure that you refit the pistons the right way round. If you look on the very top surface, you'll see an arrow. This needs to be pointing towards the front of the engine (front of the car). The bearings also fit a particar way round. The little notches should pair up so that one indent is against one sticky outy bit.

Got the stuff out mate. Anyway its much more expensive here. The rings have no marks on them
except the package says the position it should be installed

The rings

Gasket kit (seals etc)

Bearings, new set of valves

seems the head is in bad state, so had get it totally refaced, polished

new valves

looking good buddy

new bearings, new rings

Had the same problem at the same time as pos and i put new pistons, bigend etc etc still pulled like a pig so i have just fitted a 300tdi pulls like a train now best thing i ever did to the old boy

it pulls slowly because it's the 2.5na... what else do you expect! It has heart attacks on 10% inclines and can barely do 0-60 in 20 seconds, but I love it

Its finally doneup and running now, hate the running in part though.:rolly:

Whats the best speed and rpm (i have a gauge) during running in? roughly how long?

There is no set speed and engine revs. The idea is not to work the engine hard, so easy acceleration, change up so that it doesnt labour and just poodle about everywhere.

Just drive like yu are expecting to run out of fuel and get gearbox failure any minute.
