Dano Posted April 14, 2008 Share Posted April 14, 2008 the only number on my 2.25 petrol is 25273351H but this does not seem to be a regular number, does anyone have any idea what it is? Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted April 14, 2008 Share Posted April 14, 2008 Look at http://forums.lr4x4.com/index.php?showtopic=25008 Numbers starting 252 seem valid. HTH Quote Link to comment Share on other sites More sharing options...
XtremeMarineInc Posted April 16, 2008 Share Posted April 16, 2008 I've got 541874 on the 2.25 in my SIII 109. No 252, and a lot less numbers. Hmmm? Quote Link to comment Share on other sites More sharing options...
FridaT Posted April 16, 2008 Share Posted April 16, 2008 I've got 541874 on the 2.25 in my SIII 109. No 252, and a lot less numbers. Hmmm? 541874 is a block casting numkber (2.25 3mb) not an engine number. The engine number is stamped on the block (vertical) behind the waterpump.

XtremeMarineInc Posted April 17, 2008 Share Posted April 17, 2008 Ahh. I see. So it is a 3mb unit, even though it's an 81' model. Thanks. I wonder why the head and valve cover are shaped so differently from my 73' SIII 2.25??? Quote Link to comment Share on other sites More sharing options...

I wonder why the head and valve cover are shaped so differently from my 73' SIII 2.25??? 5mb engine did not come out until very late 81, early 82 FridaT Quote Link to comment Share on other sites More sharing options...
XtremeMarineInc Posted April 18, 2008 Share Posted April 18, 2008 Thanks FridaT. I'll stop worrying about it. lol. This one was built in late 80. Must just be a different valve cover design. On my IIa and III engines, the oil filler is midway between two of the valve cover bolts. On the 109 2.25, the oil filler is butted up against the front valve cover bolt. Must just be a cosmetic difference. Quote Link to comment Share on other sites More sharing options...
DEF90PY Posted November 24, 2016 Share Posted November 24, 2016 (edited) Just wondering, It's been long since someone wrote something regarding this topic but I'll give it a try. Just bought a 1958-60 series II 88 inch truck cab and the engine number makes no sense to me, E48014001. It's a diesel (perhaps the block used to be from a petrol) Any thoughts about it?

secondjeremy Posted November 24, 2016 Share Posted November 24, 2016 The original would have been a 2 litre if it was a diesel to start with. Is it a Land Rover engine? Do you know its capacity? It's possible its come from another vehicle - London Taxi - few - they didn't work well, Sherpa van, marine engine, fork lift truck. . . .

tluchette Posted January 3 Share Posted January 3 I know this is an old thread but I've still got questions and perhaps others do as well. My engine does not have a engine number. I've lightly sanded the vertical area and nothing. The surface doesn't appear to be smooth enough for a stamping. I do have the block casting "541874" with "AN" stamped above it. I have a mystery head as well. The only stamps visible on it are 6 and BM on the top left side. I was trying to find the compression for tuning purposes.

Gazzar Posted January 6 Share Posted January 6 Tell us more about the engine and vehicle. History, location, age. Photos will also help Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 6 Share Posted January 6 Have a look on the horizontal surface above the forward cam gallery cover, below the forward spark plugs or injectors. That is where later engines (2.5s)were often stamped, though more typically Tdis. My 12J had its number stamped in that same old spot behind the water pump.

Bigj66 Posted January 7 Share Posted January 7 Just a heads up (and I’m not trying to scare you) but back in the day it was common for stolen engines to have their number destroyed to prevent it being traced by punching over the numbers to make them illegible. Just with you saying the machined surface isn’t smooth I wanted to highlight this but it should be obvious that the surface is peppered with dents and looks like the surface of the moon.
