davyd8899 Posted April 23, 2013 Share Posted April 23, 2013 The existing gasket is not the standard factory fitted one, it is a solid metal gasket with orange silicon around all the holes aftermarket gaskets are never as good quality as genuine ones, it does sound like the last repair was done as cheaply as possible, never a good idea with the K series. and 36 quid for a full gasket kit including head bolts??? i would be paying that for the head bolts alone Quote Link to comment Share on other sites More sharing options...
Mark Adams Posted April 23, 2013 Author Share Posted April 23, 2013 I just found the link to show you what the current gasket looks like, I don't know where this particular one was purchased from. Mark. Quote Link to comment Share on other sites More sharing options...
Jonners Posted April 24, 2013 Share Posted April 24, 2013 Hi Mark, By stand down I guess you mean the depth of the valve face below the port face. The manual does not give a value for this on petrol engines, only for diesels. So I would think this is not an issue providing the following values are not exceeded during a head regrind:- The manual states Overall cylinder head height = 118.95 to 119.05mm Reface limit = 0.2mm Max acceptable head face distortion = 0.05mm There is also a value given for the amount that the end of the valve stem protrudes above the face it protrudes from. When new = 38.93 to 39.84mm Service limit = 40.10mm (assume this means after lapping in, or recutting the seat & lapping) Cheers - John N Quote Link to comment Share on other sites More sharing options...
Mark Adams Posted May 2, 2013 Author Share Posted May 2, 2013 Well after waiting a while for my friend to find the money I decided I need it out of the way so I have paid for the work myself, I have just had it pressure tested (hot and cold) and had it skimmed. The pressure testing showed no leaks so the head was not the problem. They are also going to re-seat the valves as they were leaking and even after lapping some of them still leaked.

FridgeFreezer Posted May 2, 2013 Share Posted May 2, 2013 The pressure testing showed no leaks so the head was not the problem. Doesn't show if the head's been annealed due to overheating and gone soft though. That's the popular failure mode. Quote Link to comment Share on other sites More sharing options...
Mark Adams Posted May 2, 2013 Author Share Posted May 2, 2013 As far as I am told the car has never overheated, it certainly was not overheating at point of failure. Mark. Quote Link to comment Share on other sites More sharing options...
Mark Adams Posted May 7, 2013 Author Share Posted May 7, 2013 Hi, Can anyone recommend a good make for an MLS head gasket kit, I would ideally like the price to be as cheap as possible (who doesn't) but do not want one that lasts 10 minutes. Mark. Quote Link to comment Share on other sites More sharing options...
Mark Adams Posted May 18, 2013 Author Share Posted May 18, 2013 I have been away so have not managed to do any work on the freelander, got back any started to get it back together, I have not replaced the head and cams but when reattaching the belts I had the marks perfectly in-line and then found that the belt will not go on unless the exhaust sprocket is about 1mm higher than the inlet mark. I cant adjust it as then the belt will not line up with the teeth. It is only a fraction out but I am not happy with it, does not any know what is causing this? Mark.
