Hi chaps

Can anyone tell me what the valve timing is for a 19j, 2.5TD land rover engine, ie what degrees the exhaust and inlet valves should start to open on the firing stroke ?

Any help would great
 
I might have this info so will try and dig it out tomorrow.

Just a clarification on valve timing: it's largely defined by the cam grind (certainly the in/ex relative timing is fixed). The angle from TDC is normally quoted at max lift rather than the start of the lobe. Production engines dont generally have variable valve timing (although I've noticed my 300TDi does have a slotted cam pulley so your engine might have a similar unhelpful feature if you accidently undo the lock bolts)... but do require very accurate alignments of chain / belt marks - and for mechanical injection diesels, accurate pump timing too.

To set the valve timing acurately you'll need a 360 deg protactor bolted to the crank and a dial guage with mag base to set TDC, then find max lift on the cam. There are a couple of tricks to setting for the real top of the lobe as max lift will be sustained for several degrees... apologies if I'm teaching you to suck eggs with this lot but can xplain more if you need some tips.

Hope that helps & I can give you 19J numbers 2moro.
 
As close as i can find is for the 12J engine & in german.. if it's any good then I'm sure you can add to my start on the translation effort!

Inlet, v = before, n = after, offnet = open
Einlass öffnet 16° voT
Einlass schliesst 42° nuT
Einlass höchste Erhebung 103°noT

Exhaust...
Auslass öffnet 51° vuT
Auslass schliesst 13° noT
Auslass höchste Erhebung 109° voT

Hope that helps...
 
If you type this in capitals, change the size to 63, convert it to webdings, add a few more odds and ends, then convert it back to times2roman having translated it into Greek via Norwegian, You will miraculously get the winning numbers for last weeks Irish lottery and the complete works of Shakespeare.

Spookey or what??????????????????????????????????????????????
