Pues lo siento ...   (MakINE16V)19.2.2010
Pues lo siento mucho pero mi Rover 416si a los 100.000km un poro entre la camisa y el conducto de refrigeración que pasaba por al lado y zas....todo lleno de refrigerante,​ cambiar el motor entero y un pastón enorme. Un buen motor hasta que se jode. Lastima porque de por sí, va muy muy fino.
Not sure how old ...   (TK42138)7.1.2010
Not sure how old your Rover is. Peugeot/C​itroen almost did the same thing but just managed to squeeze in the 4th glowplug behind the pump. A nightmare to replace if they've been overtightened​ or seized. Assuming it will unwind you still have to unbolt a coolant pipe to be in with a chance to remove it. That's reminded me my glowplugs are about ready for replacement. Glad I coated the present ones with copper based grease... Your channel looks interesting so I've subscribed.

The oil is semi-syn, since synthetic costs arm and a leg, this costs OneHalf but has good enough lubricity (MB228.3) The 4-cylinder engine has 3 glow plugs, as Powertrain Ltd. engineers found they could not access the place behind the injection pump. Howeve​r, this is the first engine (maybe ever) to use sensor detecting the lift of the injection needle in the nozzle. That way it knows precise injection start and can adjust it precisely too! Great idea and cheaper than CDi too!
Sounds like a good ...   (TK42138)7.1.2010
Sounds like a good engine. I'm guessing you carry out regular oil changes with good quality oil? My '97 Citroen Xantia 1.9 TD has done163,000mi​les and also passes smoke test and according to the test centre the emissions are virtually the same as the day it was made. However it averages 48mpg and will struggle to return 51mpg but that's due to engine driven hydraulic pump and the car's weight.
It takes maybe 10- ...   (picmario)6.1.2010
It takes maybe 10-20 minutes of light driving, sometimes not even that to get some heat. It never overheated - this engine is the original source of PRRT external thermostat - the diesel engine is simply so much effective that when you have heating fan set to "3" (since 1 and 2 do not work), in winter it takes too long. I don't complain, the fuel consumption is low even by todays standards and it passes emission tests with only ~28% of the allowed smoke. All that at 260000km with bleeding turbo
Do you mean engine ...   (TK42138)6.1.2010
Do you mean engine stays at operating temperature then overheats after 10-20 minutes or it takes that time to heat up? This is a classic symptom of most diesel engines of this era unfortunately. It's due to the thermally more efficient nature of a diesel.
Now compare those " ...   (picmario)6.1.2010
Now compare those "cars" with the Rover 400 from 1995. It was criminal act to use such a faulty thermostat idea in the first place. It was a managerial fault not to use the external thermostat that was already in use on the diesel engine.
mickey: that is the ...   (picmario)6.1.2010
mickey: that is the fault of the company to mount the external thermostat and water/oil heat exchanger. Currently Land Rover instructed repair centres to replace the lower oil rail with a tougher one and to install the external thermostat, as this really solves the HGF problem. The way the thermostat is originally done in K engine is criminal, and is known to boil off water in Škoda 100, Škoda 105, Škoda 120, etc, etc, etc.
In Swavesey, ...   (TK42138)6.1.2010
In Swavesey, Cambridgeshire there is the MGOC that specialise in MGF's and the K series. Seeping hoses and O-ring leaks are what contributes to early demise of a K engine. Shame really because when they do run properly they are smooth and revvy.
The diesel engine ...   (picmario)6.1.2010
The diesel engine has much in common with the K series, but it has PRRT since the beginning, and oil has heat exchanger with the coolant. These two aspects made it way more reliable from the start. The truth is that I can't get the diesel engine to operating temperature for more than 10-20 minutes of driving during winter with fan on.
The only MG/Rover ...   (picmario)6.1.2010
The only MG/Rover specialist in this country is me now! :D All I am going to do is that the system used on rover 420D diesel engine, including the thermostat and probably the oil cooler too, am going to mount on the petrol engine - when I fix that one, that is. The diesel had it all the way and had little problems. We​ll there is still the seeping hose that is on a sandcast alu piece that goes to the engine, but that is a design fault across the range.
This engine was too ...   (TK42138)6.1.2010
This engine was too clever for its own good. Just a shame they used plastic dowels to locate the head instead of the proper metal type. Bloody BL/Rover penny pinching and short sightedness. That's one of the reasons why Rover went under. Rover should have stuck with the Honda engines as found in Rover 216 and 827.
Try to use pressure ...   (TK42138)6.1.2010
Try to use pressure bleeding and filling for the K Series. Most MGF/Rover specialists should have the equipment and it's possible to buy similar on a DIY basis so long as you've got access to an air compressor.
You need a ...   (picmario)23.11.2009
You need a three-way thermostat and different piping to use it in a constant flow trough the engine mode, an external termostat too. (PEL500110). Also, you need to completely drain the air pockets upon filling the engine - about 5 air release point in total, make sure the two air release valves work well.
please!!!somebody ...   (leo6985600409)18.10.2009
please!!!some​body help me,if i change the thermostat,so​ the water start to run before 90 degrees,is it possible to save it from the damage?now i have 50.000km and there is not any oil leak.greetings from greece

a watch dog report and personal experience. a friend bought a 1.8 litre 75 in 2001 and had HGF3 times in 75,000 miles, another work colleague bought a 1998 freelander 1.8 and had HGF twice in45,000miles

Fundamentally, the design is good but the execution although the execution was poor - most likely down to under investment in R&D. I would like to see how the SAIC (unit fares (for all their resources) with HGF and whether this has actually been engineered out. If this is the case then the through-bolt design can be fully justified.

So you are basing this on what you've heard? What data are you using?

20k is the norm for the later ones, I know someone who bought a brand new Freelander and has had HGF 3 times in the 55k miles it has done, this is typical of most MGR K series products
.. in a sense ...   (TheSaintST1)5.5.2009
.. in a sense giving credeance to this idea. Use of an MLS type gasket and the modified oil rail (bottom section) can relieve the problems as can using the PRT thermostat which can help to regulate the water inlet into the head better on warm up. But you say that most HG's go straight after 20k.. Well if that's the case then there are a lot of mech which aren't following the book closely. This engine has very, very strict tolerances and can't be repaired just like any old ford/opel/toy​ota engine
The problems were ...   (TheSaintST1)5.5.2009
The problems were mostly from the cooling system working in the opposite way from other systems in a bid to control emissions from cold starts and if this had been done the conventional way, we certainly wouldn't be seeing cases of distortion that would leadf to the HGF problem. Interestingly, high milegae cars have been using their original gaskets whereas cars used mostly for town have seen these problems manifest themselves at around 80-90k (on the original gasket).
