pitscars Posted January 12, 2019 Share Posted January 12, 2019 Hi all - have just installed and got going my "mystery" EA81 (short block that had been in the shed for years) - runs very well - starting from cold the motor sounds as it should but as it warms up a valve train tick appears (not TOO loud but annoying) - it seems to be coming from the centre of the motor but its difficult to be sure - I am thinking it could be a worn lifter - any thoughts out there ?

Crazyeights Posted January 12, 2019 Share Posted January 12, 2019 Try adjusting the valves? Assuming it doesn't have hydraulic lifters of course. Quote Link to comment Share on other sites More sharing options...

pitscars Posted January 13, 2019 Author Share Posted January 13, 2019 Thanks for the replies - I am going to re-adjust the valves (solid lifters) (it seems only one is ticking) - I did set the exhausts at a tight 0.20 thou - the motor is a bit of a Frankensteins monster so maybe things need to bed in over time - still - the tapping doesn't sound like the usual rocker shaft tick - the car (Brumby) has no oil pressure gauge but the oil pressure light goes out within a couple of seconds on startup - using this core was a bit of a gamble but it seemed to be in generally good condition - no ridges in the bores - no sludge in the sump - a slight golden hue to the internals - from memory the guy who gave it to me said that he used the heads off it for another project - any rate we will see what happens - Cheers Quote Link to comment Share on other sites More sharing options...
jono Posted January 13, 2019 Share Posted January 13, 2019 I set my EA81 hot @ 4 thou for all eight valves but that was with a 16/56 can. Think I used same for 20/60 You put it together - how werelittle end bushes? Oil grade? Frankenstein still needed to observe tolerances. Did you check? That golden hue ...only better is new !

pitscars Posted January 14, 2019 Author Share Posted January 14, 2019 I didn't disassemble the core at all - apart from taking the sump off - it was a bit of a gamble - I had 4 short motors to choose from - all very unknown quantities - any rate I took the old girl for its first drive last night (after it sitting around for a couple of years) and it went well - I even thought the tapping had slightly changed - not such a sharp tick - anyway I will take it for short drives around the place and hopefully it will self heal - I do have a recon EA81 motor that has a loose camshaft drive cog - my next project - will be my first effort at splitting the cases - Cheers Quote Link to comment Share on other sites More sharing options...
pitscars Posted March 11, 2019 Author Share Posted March 11, 2019 Well - yesterday I drained out about a litre of oil and added half a litre of Mobil 1 5-50 - started it up - and as it warmed up the lifter tick was still there but was varying in loudness - by the time the radiator fans came on the tick had all but disappeared ! - maybe a lifter was sticking in its bore ? - not rotating ? - had some crud in the oilways that dislodged ? any rate I am pretty happy - the self healing EA81 !
