ejparrott Posted April 27, 2012 Share Posted April 27, 2012 I'm reliably informed that the Series 2's 19J has 2286 glowplugs, if not even a 2286 head. As it now appears all 4 glowplugs are in fact dead, and could be the sole cause of the reluctance to start, it had me wondering. Are the 2286 and TD glowplugs interchangable does anyone know? I have a set of 19J glowplugs from my old TD, 3 of which work for sure, and was wondering whether they would fit the 2286 head, if it is indeed a 2286 head....

ejparrott Posted April 27, 2012 Author Share Posted April 27, 2012 Some photos may help... The engine has run astonishingly well for at least 8 years, and this head has not to my knowledge been fitted during this time. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted April 27, 2012 Share Posted April 27, 2012 Looks the same as the 19J in my 110 to me. But then I've never studied a 2.25D in great depth. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted April 27, 2012 Share Posted April 27, 2012 Dunno about a 2/14 head fitting, the 2.5 NA head is the same, and the na and td share alot of parts, including the heater plugs.. The heater plugs in that engine look like the ones i had in my 19j. Does explain why that engine smokes at start up though! Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted April 27, 2012 Share Posted April 27, 2012 (edited) The series 2286 plugs you have are M14 x 1.25, probe plugs for coiler 2286 & 2.5 are M12 x 1.25. So in short they are NOT interchangable. Also a 2286 head has smaller hot spots than a 2.5, so what compreeion ratio is it running??????. Simple maths. 2 1/4 engine, 23:1cr. 2286 / 4 = 571.5cc per cylinder / CR of 23:1 = 24.8478cc combustion chamber. 2.5 engine, 21:1cr. 2495 / 4 = 623.75cc per cylinder / CR of 21:1 = 29.7024cc combustion chamber. So a 2495 / 4 = 623.75cc per cylinder / cylinder vol of 2286 head = 25.1:1cr, no wonder it started with no working glow plugs.

western Posted April 27, 2012 Share Posted April 27, 2012 Series 2 & 3 vehicles where never fitted with the 19J Turbo diesel engine, Quote Link to comment Share on other sites More sharing options...
steve b Posted April 27, 2012 Share Posted April 27, 2012 As said above the heater plugs are different size threads , a nice clean engine there cheers Steveb Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted April 27, 2012 Share Posted April 27, 2012 Series 2 & 3 vehicles where never fitted with the 19J Turbo diesel engine, The 19j been retro fitted Ralph... I think its probably the best running 19j i've seen. Quote Link to comment Share on other sites More sharing options...
western Posted April 27, 2012 Share Posted April 27, 2012 The 19j been retro fitted Ralph... I think its probably the best running 19j i've seen. ah, that helps, didn't spot the turbo in the first photo. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 28, 2012 Author Share Posted April 28, 2012 So is it a 2286 head with M14 plugs, or a TD head with M12 plugs? I havent the time to look today, fitting PAS to The 109. The owners coming for it later, I might get him to do it before it goes. These plugs are wired in series too, so need a resistor? The ones off my old 19J are wired in parrallel and so don't need a resistor... Quote Link to comment Share on other sites More sharing options...
steve b Posted April 28, 2012 Share Posted April 28, 2012 the wiring in series suggests it's a 2286cc head I'd say . If the plug thread is the M14 size a compression test to check values might be in order - if its wildly higher than the book spec then a thicker HG would help to bring it back in spec . cheers Steveb Quote Link to comment Share on other sites More sharing options...

And it wont affect the compression ratio by a useful amount Quote Link to comment Share on other sites More sharing options...
steve b Posted April 28, 2012 Share Posted April 28, 2012 Oh ok , a comp pressure test would still be useful I think , just so you have an idea where it's at . cheers steveb Quote Link to comment Share on other sites More sharing options...

Wakey wakey people, it is a 2.25 head from a lateish series 5 main bearing engine, as 2.25 plugs(M14) will not fit a 2.5 head(M12). Edward if you want to drop round i will give you a set of M14 probe plugs so you dont need a resistor. If the manifold studs are 5/16"UNF, the thermo bolts 1/4"UNF & the rocker feed banjo bolt in the head is thin headed with a 1/8"BSP thread it will be a 2.25 head as that will be an imperial head. The late 2.25's & all the 2.5's were metric.90/110 2.25's have the smaller glow plugs the same as the 2.5's. Edit, Looking at the third pic the rocker oil supply has a thin headed banjo bolt screwed in the head, not the thick headed metric job that would be in a 2.5 head, so its a late imperial head from a 2.25!.
