retriever Posted March 11, 2017 Share Posted March 11, 2017 My son in law and daughter have a series 3 24v ffr with a cracked block. 2 years ago we ground out a groove in the waterway behind the starter and filled it with liquid metal and all was well until now it is leaking again. I have a early series 2 engine is the block interchangeable if I was to strip both engines and build one from the two. I know all ancillary equipment will have to be from the series 3. if is not possible then anyone need a series 2 engine and gearbox. Quote Link to comment Share on other sites More sharing options...

The engine Serial No. will give a clue to age - you may be lucky to have a matching No. or near match. You need to use the match marked main bearing caps c/with the block being used.

I did mean series 2 not 2a I think it came out of rover 80 car and put into series 2 as a replacement, Quote Link to comment Share on other sites More sharing options...
ruxy Posted March 11, 2017 Share Posted March 11, 2017 The Rover 80 car engine will be more or less same as S2 petrol , there are lots of differences to the S2A inc. almost certain the block assembly will be different in detail but the raw machined block casting 2286 cc as used in the Roverr 80 car is the same. In the 1970's a friend obtained a Landi Hartog propane gassed 2.1/4 from a fork truck , he first fitted it in his Rover 80 car and then later in a S3 Land Rover - ISTR him telling me they were the self & same engine , however I can't recall if the head CR was 8:1 or 7:1. 1957/58 , they took the 2 litre diesel block and designed the new 2.1/4 petrol block engine around it - so there is commonality here , however no commonality between this block and earlier 2 litre petrol block.

.303fan Posted March 12, 2017 Share Posted March 12, 2017 Grind the repair out, heat it up by torch and mickle electrode to weld it? Use dry fine sane to bury the repair to cool gently. Or get the block stitched. Quote Link to comment Share on other sites More sharing options...
.303fan Posted March 12, 2017 Share Posted March 12, 2017 Or if the old bare block is scrap, I might want it to practice nickle electrodes on. Quote Link to comment Share on other sites More sharing options...
ruxy Posted March 12, 2017 Share Posted March 12, 2017 Best to just get a complete S3 engine - plenty around at scrap price , something with a pre-fix like 951 (Lightweight) , 902 (civvy) , the earliest 2286cc Petrol blocks were the 2 litre first diesel , however the diesel was sleeved - the petrol piston rings ran in the bored CI. Both blocks were known to be weak - so they were strengthened improved for the start of S2A. Quote Link to comment Share on other sites More sharing options...

ruxy Posted March 12, 2017 Share Posted March 12, 2017 head casting no 279502block casting no 276678 engine no 645100591 ============== engine no 645100591 , prefix 645 means nothing to me - but as you say , off Rover 80 car head casting no 279502 = a Land Rover part no too , as fitted to Series 2 , the earliest S2A head is = Part No. 566703 however this could be based on a 279502 casting This head will be a deep head casting at the front near the thermostat housing - to use this head - you would have to check - there could be a clash with a FFR timing case cover block casting no 276678 , a S2 petrol block assembly Part No = 276908 , the earliest S2A block assembly = 541891 -------------- I would have to get a look at the oldest S2A block I have to check the casting No. I doubt if it will be a 276678 casting. If ever there was a change of casting design , change in foundry , or machining difference - then there would be casting + Land Rover Part No. suppercession changes , this was done for QC for traceability in case of problems. AFAIK - regardless of changes , all petrol 3mb 2286cc blocks are interchangeable. ------------------------- If you did use this block with all S3 FFR anciliaries , the main thing to watch for is a newer 3mb cylinder head (if used) could be a "metricated" head - therefore you would have to double-check the oil feed pipe banjo-bolt threads , seal washers etc. Quote Link to comment Share on other sites More sharing options...
