dangerous doug Posted May 19, 2018 Share Posted May 19, 2018 I bought a 4.6 short block yesterday for £100......very nice thank you! But the catch was it suffered a camshaft failure, one of the lifters got a little hungry and ate some of the lifter bore in the block. Anyone know if it can be fixed? It hasn’t eaten much but you can see and feel the damage. Or is it destened to be a coffee table? Quote Link to comment Share on other sites More sharing options...
lo-fi Posted May 20, 2018 Share Posted May 20, 2018 Any decent engine rebuilder or machine shop will be able to give you a definite answer, but this looks like a job for an expanding reamer and a small bronze sleeve made up. I'd be very surprised if it's not savable without spending a fortune. Does a lifter stick in that hole now, or is it rattling about? If you're lucky, you might just get away with having it reamed to a decent finish again, but it depends how much metal has been scuffed away.

dangerous doug Posted May 20, 2018 Author Share Posted May 20, 2018 Yeah I’ve done a little digging and it seems phosphor bronze inserts are a thing in the blueprinting world. They are also harder and produce less friction. Emailed the more well known RV8 engine specialists this morning about it. Its not that bad but it’s enough to feel with a fingernail and the way I see it, the lifter will only make it worse. Reaming it may be an option but I’m not sure if the oil flow will be the same afterwards. It would be more inclined to fall out the bottom of the bore rather than into the lifter Quote Link to comment Share on other sites More sharing options...
garrycol Posted May 20, 2018 Share Posted May 20, 2018 I would be more worried about the condition of the liners - make sure any of the liners have not slipped and get the block pressure tested - cheap blocks are normally cheap for a reason. Hopefully it is just the lifter issue which would be an easy fix. Garry Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted May 20, 2018 Author Share Posted May 20, 2018 Understand that. It will be pressure tested before any work is undertaken. V8 developments have got back to me all ready and said that a top hat block with new Cam bearings etc is £1300, which is a lot of money but it’s not unaffordable and a lot less than I thought.
