Low liners 1.8 K-series engine

Hi folks,



My Dad and his late brother have always been Rover fans as long as I can remember and the car's they had always gave good service.

My Dad bought the Rover 75 1.8 in 2005 from new and has been very happy with this car and keeps it spotlessly clean.



Two years ago a water leak from the HG started to become more serious so I replaced the HG and the car has been fine until about four weeks ago.

At first it seemed the car was over heating but and after some investigation it looked like another HGF was allowing combustion gas leak into the cooling system.



I removed the cylinder head and had it skimmed then reassembled it with new cylinder head bolts and MLS gasket, the engine started and was running fine but the cooling system continued to bubble over.



At first I thought it was just an air lock but then realised there was too much air in the radiator and something more serious was wrong.



After a call to a local friendly garage I was informed of the low liner problem and they estimated the repair cost would be far more than the value of the car, I also made a call to company that specialise in engine rebuilds and they informed me they were not keen on doing work on this engine as previous jobs they had done had not worked out very well.

I was now left with having to tell my Dad his beloved Car would have to be scrapped.

I decided to have a look online to see how common this problem was and discovered a few posts explaining how shims could be used to raise the liner height but at first thought this job would be to big and involved to take on but after reading an excellent thread posted by Beinet1 I feel confident I can do a similar job and Save my Dad's Beloved Rover.



Work has already started on this project and the cylinder head has been removed and I can confirm the liners are under the minimum height tolerance. I will post some photos and reports how this job goes.
