Hi everyone as a long term Rover owner is there a fool-proof cure to k series hgf problems IE 75 with 1.8 seem to suffer repeated problems even after repairs have been carried out. Reason for asking I have a 75 diesel but fancied a second car. Got to be a Rover obviously, 😁😁😁

You can buy the SAIC uprated head gasket, stronger long bolts and strengthened oil rail components - that's one option. Last time I saw all of these components for sale together was in the MG Owners Club catalogue (very recently). You can get complete kits for the 1.8 NASP and 1.8 NASP VVC. Not sure they work on the 1.8T - but I'll stand corrected if someone else chips in.

FAI and other manufacturers make MLS head gaskets which a competent garage can fit for you. You need to buy new longs bolts too.

Some people just say the Landrover K series headgasket fixes the problem. Again, not sure if this covers the 1.8T.

I run 4 K Series cars, my daily ZS 120, track 200, a ZR160 and a 25 that gets passed around the family. As well as these i do a fair few HG's at work and private and following this set up NONE had ever had HG problems again.... Yet :S

1. First make sure liners are at a height of 4 thou, if not shim them
2. The head is flat and the alloy is not pitted or soft
3. SAIC 6 layer gasket
4. Up-rated oil rail
5. Factory (TX marked) or Payen bolts with the original torque (i had ordered from DMGRS, X PART and none of the "new" bolts had ever had 10.9 stamped on them)
6. PRT thermostat conversion with the LandRover "grey" thermostat (designed for the K series)

With the grey PRT stat the engines take a fair while to warm up (which was one of the causes of HG failure with the factory set up) and run a lot cooler, even on trackdays in summer at full fight with the VHPD spec engine coolant temp as never been above 92 degrees

all of the above and keep on top of your maintenance schedules.
Don't keep using it for 5 second trips to the shops, let it stretch it legs.

Agreed with all that especially the liner height and I also run a PRT on both cars and the difference in warm up time is not really not noticeable , but if you have a leak and it over heats game over your head will have gone soft , that why I also have low coolant warning light , that way you have a chance before it drains a way .
