Bowie69 Posted August 8, 2012 Share Posted August 8, 2012 TBH, I'd strip it right down and start again, at least the parts are clean for you, but if they haven't replaced bearing then what hope do you have for seals and piston rings? It is rather disappointing when this sort of things happens, I know Quote Link to comment Share on other sites More sharing options...
zoltan Posted August 10, 2012 Share Posted August 10, 2012 I've never heard of line boring white metal shell bearings. Line bore the housing that the bearing is pressed into sure but not the bearing itself. If anything, mark the cam journals with engineers blue and lightly hand scrape if it is tight. To be honest that bearing doesn't look that bad, I've seen a lot worse that ran without issue. Have you measured the clearance? Quote Link to comment Share on other sites More sharing options...

elbekko Posted August 11, 2012 Share Posted August 11, 2012 Yikes. How does the crank itself look? Quote Link to comment Share on other sites More sharing options...
mikec Posted August 11, 2012 Author Share Posted August 11, 2012 There's noticeable grooves when I rub my finger nail across! Quote Link to comment Share on other sites More sharing options...
elbekko Posted August 11, 2012 Share Posted August 11, 2012 Doesn't look too bad, but perhaps run it by a machine shop to get it polished and measured anyway. Quote Link to comment Share on other sites More sharing options...
Team Idris Posted August 11, 2012 Share Posted August 11, 2012 The white metal is there in part to hold dirt rather than let it damage the crank. So it looks worse than it often is. But that has the attributes of an engine that was built up with dirt in the galleries. Everyone hopes their newly built engine doesn't look like that inside (especially me having just done mine) but you wouldn't know until you stripped it down. Therefore, I think the crank will be okay with a polish as long as it is within tolerance and isn't oval or tapered. I mean, they run okay when old with copper showing and the running face all shapes! Still a sad state of affairs to buy somthing you thought was good and find all that lot Quote Link to comment Share on other sites More sharing options...
mikec Posted August 11, 2012 Author Share Posted August 11, 2012 Yeah it's not so much wether it's usable, it's wether it should of been put I to a £1.5k "recon" engine cheers mike Quote Link to comment Share on other sites More sharing options...
mikec Posted August 13, 2012 Author Share Posted August 13, 2012 Well the company I bought it off has been in touch today. They won't send it back to lr, but want a parts list of what it needs,and are going to see what they can do, so what do people think head gaskets, main bearings, big end bearings, valve stem seals, cam bearings., rear crank seal. Have I missed anything? What about bolts are head bolts etc all reusable? Cheers Quote Link to comment Share on other sites More sharing options...
discomikey Posted August 13, 2012 Share Posted August 13, 2012 id get new headbolts, and a crank polish at least, if not a undersize grind and matching shells. take a look at the cam in a similar light too. id look to see if they'd replaced the piston rings too, and check the head/s to check theyve been skimmed. would be tempted to get new locking tabs where applicable too.

mikec Posted August 13, 2012 Author Share Posted August 13, 2012 Not sure if the rings are new or not, they look it but how would I tell? Same with the heads? The cam is being replaced anyway so doesn't matter, cheers mike Quote Link to comment Share on other sites More sharing options...
zoltan Posted August 13, 2012 Share Posted August 13, 2012 Take the rings ( top and second) off off the piston carefully with a feeler gauge and fit the rings into the bore one at a time and measure the gap in the rings. That will give a good indication on how worn the 'new' rings may be. Haynes book of lies should give figures for this. Unless you have access to a Bowers type internal micrometer measuring the bores properly is difficult. If this is a freshly built engine you should see the cross hatching left by honing clearly in the bores. You don't want to be seeing a bald and polished patch and no cross hatching on the thrust side of each bore. The piston skirts shouldn't be showing evidence of wear. £1500 is border line for parts on a V8 if you are going to do everything properly. I reached this easily when costing out a rebuild for my 3.5 in my 110 and I can get everything trade Quote Link to comment Share on other sites More sharing options...
mikec Posted August 14, 2012 Author Share Posted August 14, 2012 There's cross hatching on the bores but also one or two small scratches going In the direction of piston travel. I'll get a ring off and see. The £1.5k is just what I paid for it think the proper price was £3.5k! Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted August 15, 2012 Share Posted August 15, 2012 There's cross hatching on the bores but also one or two small scratches going In the direction of piston travel. I'll get a ring off and see. The £1.5k is just what I paid for it think the proper price was £3.5k! That sounds like its only been glaze busted, whats the wearing surface of the rings look like as new will be either a ground finish or on iron rings possibly a finish turned finish.

mikec Posted August 15, 2012 Author Share Posted August 15, 2012 Not managed to check the ring gap yet but here's some pics Quote Link to comment Share on other sites More sharing options...
mikec Posted August 15, 2012 Author Share Posted August 15, 2012 That white bit on the ring in the last pic seems like some sort of paint, or something I've also had an offer from the company for new bearings (main, big end and cam) new head gaskets, valve stem seals and one or two other gaskets free of charge, but the more I think about it the more Im not keen. If it was a new block then it'd be a different thing, but I'm not sure what's actually been done to this engine recon wise. Quote Link to comment Share on other sites More sharing options...
discomikey Posted August 15, 2012 Share Posted August 15, 2012 as long as it is within spec, and clean, and without serious damage to any of the major components, there is no reason not to take the new parts offer and rebuild it yourself. can you feel the vertical scratches in the bores with your fingernail?

Landrovernuts Posted August 16, 2012 Share Posted August 16, 2012 I am not sure if it is the way the picture is taken or just me, but the top liner picture looks like the liner has dropped in the block! Toby Quote Link to comment Share on other sites More sharing options...
