200tdi or 2.5 ? 2.5 with cast iron head which do have replaceable guides that can be knocked out and hammered back in with a special punch but pressing is the best

in theory but to will have mushroomed a little over time ,you check valves by fitting in guide lifting a little and wobbling to see what play there is

Right explanation, bear in mind this is only forensic investigation for curiosity reasons.
Taking out the valves all was going well until no. 7. This inlet valve was really stiff to get out to the point I had to take a piece of wooden dowel and tap it with a hammer. Even this took several taps moving a little each time. It was only stiff for the last inch I'd guess.
So I measured the valve as you can see. All the other valves were uniform along their length. If anything the very end, shown in first picture, was minutely under. Valve 7 however, the end was .08mm larger than the rest. It wouldn't fit in any other guides and other vlaves would fit in guide 7.
Strange to be only one valve, until I remember the most bent pushrod that we struggled to pull through the head was no. 7.
Also valve 7 had a lot more crud on the back side than any other inlet Valve.
the right one has mounds of stuff solidly stuck on.
What would be the knock on effect of this, if any? If it took out that piston or significantly reduced it would the engine still run on two. could thus be why no start?

Morning. I only had a couple of hours on the truck today as I didn't fancy walking back from the lock up. First thing was pouring a glug of oil into each cylinder. Which surpriseingly didn't drop in level for the hour and a half before I left. :thumbup: things are looking up for this engine.
I spent the rest of the time trying to get the sump off. Those bolts are barstools! Only got a out 8 out. Any advice for rounded heads?

Eventually got the sump off. Sp00k didn't get the extractors in the end. The last two stubborn ones were a pain. Spreading the heads out with a cold chisel gave enough purchase to get them out though.
Inside everything looked good, well what I could see. I was expecting to see the crank ect. I wasn't really sure what I was looking for. Still the sump was all clean with no debris in the bottom.
The search goes on

Evening. Few questions about replacing the engine. The guy my dad was speaking to said I might as well have the gearbox out of his disco as well, apparently it's the best one. :what:
So last night I checked the box number to try and find which one it had in it. Having found the number it was no clearer. It was P19743 ffs0047992g any ideas?
He also said it would be worth breaking his box off to replace the clutch plate and arm before putting it in. Is there anything else you would suggest?
would appreciate any advice
