la bala Posted March 16, 2013 Report Share Posted March 16, 2013 Hi lads, do any of you overhaul your landy engines. About a year ago my old 2.25 diesel started smoking and getting through oil, i completely rebuilt the head with new valves, springs, valve inserts and seals, bores and bottom end was ok. Two weeks after rebuild it started to smoke again, when i took head off, two of the exhaust valve seals had come out of groove and were going up and down on valve stems.I wasnt totally happy with the seals when i fitted them, but when you buy aftermarket you get what you get. Anyway off to land rover dealer and bought seals at about 24quid. Four weeks ago, smokey landy again, took head off today, all four exhaust valve seals out of there grooves and half way up valve stems. any landy owners had this happen?

barney 66 Posted March 16, 2013 Report Share Posted March 16, 2013 Never had this trouble on the 21/4 petrol engines I did years ago,dont know if it helps but I always soak my valve seals in oil the day before,somebody told me to do this nearly 30 years ago and I have never had any trouble. The petrol series I had I rebuilt the engine with ring big ends mains valves and guides,and when I took the head off 9 years later the seals were still in place although a bit hard,only took the head off due to pressurising the system,turned out to be blockage in the header tank,forgot to mention Payen gaskets I always used Quote Link to comment Share on other sites More sharing options...

Big Mat Posted March 16, 2013 Report Share Posted March 16, 2013 did the seals come in a blue box? anything rubber or with moving parts dont buy ****part I'd agree with that! I've had a starter motor and a clutch slave go up the spout, all came from those little blue boxes! Quote Link to comment Share on other sites More sharing options...
la bala Posted March 16, 2013 Author Report Share Posted March 16, 2013 did the seals come in a blue box? anything rubber or with moving parts dont buy ****part best part of it is, the original inlet seals came from that place and they havnt moved, originally i replaced the cheap exhaust seals with land rover ones which now, twelve months later are doing the same thing. but there, the valve stem inserts came in a blue box, you pay your money and take your chance.
