It is where the modern generation of engines have gained efficiency and so output. Musgrove was especially passionate about this – and barracked the then Trade and Industry Secretary, Norman Tebbitt, into seeing the BL point of view: it worked – Tebbitt was persuaded and the Government capitulated, allowing the continued funding of the K-Series. Nobody else puts a thermostat where it is on a K series!? The last thing anyone wants in a race car and I am sure this contributes to the sudden over-steer that the Elise suffers from. Thank you very much. Replacing this mount with the original Rover 200 mount not only stiffens the engine mountings but saves a lot of space and weight! This highlights another of the unfortunate practices that is currently going on within the aftermarket tuning companies: the replacement of the long bolts by thicker and stiffer material. What amazes me is that the issues were never discussed let alone properly understood, and I continue to hear from people at Lotus that Rover couldn’t develop K, an assertion that has no basis in fact and since Lotus have not met with Rover’s Commercial Director to ask, these assertions seem almost to be negative briefing. This is always evident on the bruised skirt from 1.8-litre pistons and therefore as a matter of efficiency, if not reliability, the liners, are better replaced by the Chromoduro liners which are not only made in steel and have the low friction lubrichrom coating but are toleranced to not move around in the bores and give the ideal 5thou stand-proud. Out of Aluminum alloy, with additional coolant passages for liners and head gasket fire rings and CNC machined. This works by injecting liquid aluminium into an upturned sand mould from below. An 80mm bore 1.6-litre was, in fact, extensively tested as a wet liner in the early closed block but the liners tended to crack – this occurs with iron liners because of loads imposed through the block acting as a moment at the top of the liner, though this happened at the very high mileage cycles that road engines are tested at. My 75 is a 1.8K, not the turbo. No loss of oil or water!!!! Cam Coat also have such a coating, but also offer a coating for steel valves, as well as low friction coatings for piston skirts. Being heavy and 4×4, the 1.8 litre Ks tend to be pushed very hard from cold. advanced materials, computer designs and weight reductions. A level of 40 gm/mm represents the required level for an engine spinning to 9500 rpm. Prometheus Mk V is a revolutionary engine Myles, a serious and able engineer, told me of their problems and efforts to understand them, of even doing a tranche of tests with vibration sensors mounted all over the block to measure what he considered to be the engine’s weakest feature. with the aim to increase power obtained from fire. An insider described the earlier engine as very much a practice run, produced in an almost hand-built way – unfortunately, that led to fragility in the 825, and many power units expired before they hit the 60,000 mile mark. Early in 2005, Rover introduced a new thermostat, the PRT thermostat that will open with pressure as well as temperature, the result is that it opens much more quickly and prevents this thermal shock across the engine. All in all a good effort, but like many British designs, half baked. …and then walks you through the failures – and the fixes. check your fluids regularly. I became suspicious after about 2000 miles that the gasket was on its way out. Personally, I don’t like the sound of it, over the past year I tried both a W211 2003 E500 and a 2000 CLK 430, and they just didn’t sound… ‘meaty’ enough. 274.8 The K-Series engine could have been the best thing since sliced bread – and in many ways it still is. Although in good condition and sound in all other respects, the car has actually blown its head gasket twice since I bought it – The point is that big bore short stroke engines are conceived to make high engine speeds possible, the penalty is poor torque, the Honda 2.0-litre S2000 producing just 151 lb ft @ 7500rpm, a figure easily eclipsed by the 1.8-litre K equipped with Piper’s 1227 cams, which will give a very similar power output to the Honda engine.

Common is ‘that these engines are only involved in club motor sport and to take the engine building to a higher level is unnecessary and expensive.’. I did not find it. In 2003, the standard Rover liners were re-specified, for much better fit to the block and stand-proud. I’ve never had to deal with it on a K series , so I do not know the precise remedy , but it was very common on the Triumph 4 and 6 cylinder ohv units as a result of the centre main bearing cap thrust washer spinning and dropping out . This poses a difficult problem with cast-in liners. What is totally amazing is that these companies, particularly the sports car manufacturers, have not gone to the Rover Design Engineers for any help or advice at all. Quite simply the K is a very remarkable engine, the best four around and uniquely suited to motor sport, far more so than the heavy Japanese copies with all their over-engineering and most particularly the 2L Duratec with its archaic bearing cap design. My 75 is a 1.8K, not the turbo. accuracy that we have and characterize VGKracing coolant temperature is lower (if you use a 71/74 I believe the later Chinese engines are far better, at least the 4 cylinder versions, and head gasket problem have all but been eliminated! The head gasket was replaced (along with the cam belt). Which is shocking! No mention of 178bhp vvc in tomcats!? - Fill the oil filter several times until completely soaked -When the ECU map is finished optionally you can put a Metal Lube "Formula rpm. A – It’s what’s known in the trade as piston slap, nothing really to worry about. Q Was the K-Series entirely a British engine? The K series engines have been in production since the early 90’s and give good service with the exception of the head gaskets which have proved to be notoriously unreliable. It is important to realise that there are different modes of gasket failure, but both gasket and liner failure are and always were symptoms not causes. In other words all the steel crankshafts are at least 10 times out of tolerance for a standard engine and more that 20 times out of tolerance for an engine with a raised rev limit. PS I still love my 75!!! On 8 May 2004, Clive Danks and Ian Fleming actually attended a meeting with Tony Schute, Jeff Grose, Paul Birch and Ian Colley with a view firstly of dealing with the perceived unreliability issues of the K, but also to discuss supplying new versions of the K to Lotus. This can allow the liner to rock in the block, come away from the fire ring, and eventually split. Only the Yamaha/Ford Puma engine at 86.5mm and the Yamaha/Toyota VVTi at 87.5 are narrower. The K-Series could have made the company a lot of money and ended up with a superb reputation. This level depends upon the engines use and its maximum speed of rotation. The engine is a total catastrophe and should never have been sold or fitted to any car and is very largely responsible for the reputation that the K suffers. In front of the engine, there are: 1 hot exhaust manifold, 1 thermic insulation shield, 1 fan +1 thick coolant hose. Regards. Seems everyone else knew!? 22.8 As long as the engine had been fitted with steel dowels and you let it warm up before thrashing it there were few problems. The plastic dowels have had one unfortunate consequence in misleading many into thinking that there is a problem with the liners themselves. Can someone please tell me if I can swap in a SAIC KAVACHI K Series 18K4G long block engine ( I will remove the turbo ) to replacement with my 18K4F which I have in my Lotus Elise S1 My1999. 708.5 However, effective the PRT thermostat is for a road car, a far more effective solution for any engine used on the track, and in fact any Elise with its problematic long coolant hose runs is to move the thermostat to the output side of the engine. The Rover engine’s compact size and weight are a significant advantage in a lightweight race/sports car of the Lotus 7-type or the Elise. The belts on the K actually have a 120,000 mile life and in the same way as for the KV6, the K4 would not be presented with any problems passing endurance tests required in the US. However, the Engineers are quite clear – the blocks do have slightly different figures for stiffness, but the later block was designed to be as stiff in every required axis as the earlier block. Yes, we will ship your Rover K Series engine anywhere in the world (providing we can find a courier who will do it!) LM25 is a very adequate metal used in the better mass produced engines today. Much of our head skimming machine time is devoted to the Rover K series heads from both private and trade customers. A – In most cases, the problem revolves around four common threads as follows: Q Will these engines really go the distance between timing belt changes? The move to the plastic type was said to speed up engine warming and reduce emissions. Q Why does my engine sound like it’s knocking for a few minutes after a cold start? The mapping is extremely poor, the engine running far too rich, all of which mean that the engine is well down on both power and torque and exhibits poor emissions and excessive fuel consumption. A clear example of which is the example of Scholar’s EVO4 block. is greater. This can cause enormous thermal gradients across the engine, causing both distortion of the head and block and also gasket failure. The original engine had a top hung wet liner, now replaced across the 1.4 – 1.8-litre range with a floating half-wet liner. Anyone know what type that is. -During the first 3000 kms always check Buy Rover K Series 16v Engine 1989-2005 Reprint by Des Hammill (ISBN: 9781841556888) from Amazon's Book Store.
