4.6 V8 slipped liner??

Took head of right bank of 4.6 v8 its a late one done 30k miles rebuilt a month ago replaced a liner as it had a crack radiator failed last week hg blown head off now on pots 2 and 4 if I run my nail across the join between the block and the liner it catches not much but just a little - has the liner moved?
Any ideas welcome chaps

I might whip the other head off and have a look

How did you replace a liner?

Sent it to a machinist local to me

Should really have had them all 8 top hatted at the same time. Liners slipping are almost a guarantee on the V8.

Was just wondering how they removed and replaced just one liner (Heating block, freezing replacement??) why just one. New rings?

The engine had only done 20k and had a crack in no 8 very small but just visible there was no slippage of liners but it blew top hose clean off my local man replaced the liner I rebuilt it ran like a dream and rad let go because a I didn't put a new one in and b faulty cap so cooked again so here we are my dearly beloved wants me to sellit or burn it but I love it and will just rebuild her again

Right I had a mate over who is an aircraft engineer who is of the opinion that I am being paranoid and that the liners havent slipped he also pointed out that the two are nos 2 and 4 and the heat was between 6 and 8 anyway he has convinced me to have the heads skimmed think this is the last one not a lot of meat on there and reassemble so my cost is a head gasket and bolts so going to try it as when I did the rebuild forgot to put the engine lifter on the back of the thead oh and I also believe in fairies and santa clause.
Will keep you all posted on outcome but am ready to replace the liners or block
