Rangie Engine advice please.

[Cassillis]

Hi all, never posted in this section before so bare with me.
An acquaintance bought a  V8 4Ltr Manual Rangie on an M plate, about 1995 i believe?
Bought it from a so called friend. Soon discovered that it was over heating badly. Came to my mates workshop for diagnosis.
Lots of milky cream in the cam covers etc which was diagnosed as possibly a head gasket gone.
Stripped the heads down to find the set up was almost brand new as if it had been done very recently. Suffice to say no fault could be found with the heads etc.
Would i be correct in assuming that the next step would be to get the block pressure tested and go form there.
Or should the owner be looking to source a replacement engine, i understand the 4Ltr ones are rather hard to find :?:  

Any comments or help would be greatly appreciated

Thanks

The 4.0 is the best of the bunch .... so surprised the block has gone. RPI etc do short engine replacements  .......

Get a test done to confirm tho .....

Yes, the next step is a hot pressure test or a short engine.  The 3.9 was nominally the same stroke and bore IIRC, jus a matter of maths that adds a few CC so it rounds up to 4.0 not down to 3.9.

The 4.0 is the cross-bolted lump with bigger joournals on the crank, but even a goosed one will fetch a good few bob because there is demand for lumps to recondition.
