Hi Guys, Before swapping engines , i would like to do some adjustments to my old 4G54 2.6L petrol engine. Does Anyone know the valve tolerances (intake and exhaust) in inches or mm.

Thanks for the answers.

Not quite sure of your exact question but :-
- valve length, inlet = 108.0mm, exhaust = 105.9mm
- valve head thickness, inlet = 1.2mm, exhaust = 2.0mm
- valve seat contact width, inlet = 0.9-1.3mm, exhaust = 1.2-1.6mm
- valve stem seal installed height = 14.7-15.1mm
- valve timing, inlet opens at 25 deg BTDC, closes at 59 deg ABDC
- valve timing, exhaust opens at 64 deg BBDC, closes at 20 deg ATDC
- valve springs, free length = 47.5mm, installed height = 40.40mm
- valve guides, inlet length = 47mm, exhaust length = 52mm
- valve stem to guide clearance, inlet = 0.03-0.06mm, exhaust = 0.05-0.09mm
- oversize valve guides available = 0.05, 0.25, 0.50mm

Hi, I have found this info from web....
http://myweb.tiscali.co.uk/pajero.shogun/techdata.htm


The model data will be for both Metal Top (SWB) and Wagon (LWB) specifications.

Engine displacement of 2477cc diesel and 2555 cc petrol

It will cover manual and automatic transmissions.

Unless each data specifies the model as relating to a particular body/engine size/transmission, please assume it covers all.

(This is a mere sample covering two engine variants and two body styles. For full technical data covering all Pajero models from 1983 to 1996 please go to the merchandise page for details on the Haynes Workshop Manual which is now available through the Club.)
