Got a quote from Footman James for my 300tdi disco with mods and 5000 max mileage for £220 . Same price as the insurance on my volvo with 9yrs no claims

I've drained it by removing the plastic sedimenter plug and letting the derv out into a bucket, took days with a full tank, remember to check the bucket occasionally. Might be quicker taking the sed right off?

Ok Thanks James, I'll measure again from the very bottom cheers.

I'm measuring at right angles to gudgeon pin hole, half way between hole and piston skirt. Somehow it's less than std size, I'm confused!

Sorry I should've mentioned that the cylinder bores are within tolerance for Standard diameter (90.47 to 90.647), it's like a smaller piston from another engine's been used

So I've stripped down the engine of my disco to try and locate an engine noise and steam leak. I've been measuring the tolerances today and found that 3 pistons are 90.37mm in diameter, but piston no1 is 90.05mm in diameter, I have checked and double checked. With the head off, No1 piston could...

Further investigation reveals the cylinder bores have been 're-sleeved and there are exhaust valve imprints on all pistons (after cleaning all the carbon off so must have happened a fair while back. I thought I knew the history of this engine having driven it for 100k of its 230k miles!

Mine's P reg, inside the door cards are stamped Jan 97 and it's manual pump non EDC. But then it doesn't have leather seats or sunroofs. Could it be related to the trim level rather than year of manufacture?

Thanks for the reply, I'll take a closer look if it stops raining ( it's an in-car rebuild).:)

Just started an engine rebuild project on my Disco, with the main purpose of locating an 'invisible' water leak and engine noise, finally started it after suddenly started burning oil. Got the head off now and was checking the cam follower sliders, all look ok but several of them have the F...

Thanks for offer BLASER much appreciated. But good news, managed to shift it, couldn't chisel it, but stud extractor set from screwfix £9.99 did the trick. Should've heard my language when it shifted after three evenings trying

Went to top up gearbox today and found that some Muppet has rounded the inside of the filler plug. I suspect it's been overtightened and rounded with an air tool. Any suggestions for it's removal please?

The saga of the noisy 300 tdi continues, especially after hearing the nice purring sounds made by other 300 tdi discos at the local show at the weekend. I've used the stethoscope to go round the engine, the loudest noise seems to be coming from the injection pump pulley behind the timing cover...

There some M8 bolt holes on the pulley. You make a Y shaped tool out of 2 suitable flat metal bars. It's mentioned in the Haynes manual. You should use it to undo the pulley bolt too.

Had a similar problem, temp gauge would go up to max and go down when handbrake applied. handbrake cable would heat up and smoke. Fitting a new engine to gearbox earth strap fixed it. Check all the earth connections, clean them up with wire brush etc. 2 in engine bay, near battery. Engine...

Good question! I'd like to know too. Mine's blowing oil from behind the crankcase breather and you can feel the pressure when undoing the oil filler. I read a post on here where the dipstick was being blown out of it's tube! Mine's not that bad though.

Did mine a few years ago now, so a bit hazy on the details. It took me all weekend from start to finish. Just persevere with the clips, they went on in the end, think I used a screwdriver, I remember swearing quite a bit. Sometimes helps to get down to eye level with them. When I put the dash...

How many miles had the old ones done?

Had the rocker gear out, all looks ok, push rods are all straight. Starting to think it's more serious, small end bearing perhaps. I solved the mystery of the oil light coming on at the top of a motorway hill now as its happened twice since. Symptoms are: loss of power, jolting and engine...

I think the prop bolts at the transfer box end are only removable when the transfer box output flange nut is undone and flange removed. I wouldn't change them unless the felt washer is leaking. It's an M20 nylock which is expensive from the main stealers. I always change the prop nuts but never...
