Ive just pulled a 3.9 EFI engine from a disco, its very very clean, no engine number or com' ratio on the pad ( by the dipstick) The only thing I can see is stamped letters, WT WT 51 located on the pad that the old P6 rovers used for the engine number. In the push rod vally it has 10 in white marker writen twice, its a v belt engine with the cross bolted bottom end but its not been drilled / tapped for the cross bolts. the oil pump is driven from the dizzy shaft.
The engine has been painted with a silver paint, which has a very very light tint of green.
It looks like its been remanufactured by some one, any ideas? thanks

Now its been degreased it has a badge on it stating its a LandRover factory remanufactured engine, it looks like the liners are sitting on a ridge, so they should not be able to move, does any one know anything about these, is there anyway of decoding the numbers on the ali' badge? thanks

I think all the interims were 9.35 CR - If it has the full main caps then it's a good foundation for a build. How many head bolts?

I deleted the 3rd set of bolts on my engine, never caused a problem, then later fitted a pair of TVR challenge heads, which were genuine 10 bolt heads

Cross bolts, Ive just drilled & taped them for M10 bolts,its a strange match of parts, the block has the two tapped holes for a cam plate but it only has the early non located cam. Hopefully it has little core shift & the wall thickness behind the sleeves are not thin..

They are considered to be the best of the small journal blocks available and seldom if ever have any liner issues - I have used one for the basis of a 4.5L build - there are bits about on it in my G27 thread. They are very sought after especially once the cross bolts have been fitted.
