engine knock - help!
guys need your expertise help please if you can- got a v8 engine in disco, started and drove like a dream, until i replaced the carbs with new twin webbers. After replacing them it run fine until it conked out and stopped, after which i couldn't get it started, so i attempted to put it 1st gear and kept cranking it in gear so it may start, but it didn't start and by doing that i flooded the carb and the petrol was all over the inlet manifold. Got it recovered to a garage and found that all the oil was contaminated with petrol, so gave it an oil and filter change, then started it up and it was knocking, we thought that knocking was due to hydraulic tappets being knackered, which we changed along with new rocker shafts and push rods. fired it up and still knocking, engine runs fine but its got a knock- could it be camshaft or BE bearings? ive taken the sump off and checked the BE - photos attached of one of them - could these be the culprits? or what damage could it have done by cranking it - please any help would be appreciated

Firstly
What oil did they use for the refill. 20w50 is required, good old Dynosaur juice for the old engine.
If it is modern lightweight stuff it will fail to pump up the liftersproperly/fully and not properly lubricate with Rover tolerances.
A tappet sound on these engines is regularly a leak at the exhaust manifold gasket.

Then its time to check your crank rrealy carefully before you put new bearings in. Otherwise they could be thrown out within 100 miles again.

I would avoid cheap crap off ebay.
You could go for ARP studs if you wanted, they are better than bolts for several reasons.
