T.bailey Posted May 10, 2018 Report Share Posted May 10, 2018 On the drive home last night oil pressure at 2000rpm was around 45psi, so I think I'm ok. Will keep an eye on it though. Thanks for the advice chaps. I'll also be shortening a drill bit this evening now in addition to doing the tappets, as I wasn't imagining the increased valve noise. I'm firmly a metric baby, so I have a lot of learning to do now I've bought a GT6. I always hated fractions at school. Link to comment Share on other sites More sharing options...
Guppy916 Posted May 10, 2018 Author Report Share Posted May 10, 2018 Morning Mr 'T' maybe time to retorque the head down then readjust the tappets and go from there Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 10, 2018 Report Share Posted May 10, 2018 As we showed on the september twiddle day use an old feeler in the tappet to identify a odd noise one which seems at the correct gap but clatters due to worn pads Use the rule of 13 or bet the opposite compression rocking and do both inlet and exhaust together (saves turning the engine much) Retorque first mk2 7/16"stud 65 -70lbft, back off 1/2 turn then re torque in the planned order do one at a time Pete Link to comment Share on other sites More sharing options...
T.bailey Posted May 11, 2018 Report Share Posted May 11, 2018 So I did the tappets last night, didn't see the bit about re-torquing the head down in time. All of them had no or almost no clearance with feelers. I set the clearances and now there is still a lot of valve noise. I'll have to have a look tonight for rocker wear etc. I may have to invest in one of these click-adjust things to account for the rocker indentation. Pete, I don't suppose there is any info available on the technique shown at the September twiddle day? Thanks for all the advice. Link to comment Share on other sites More sharing options...
NonMember Posted May 11, 2018 Report Share Posted May 11, 2018 A bit of valve noise is not uncommon, and a LOT easier to live with than the consequences of not having enough clearance. That said, if you had valve noise when there was no clearance it suggests something else is up. You could try the stethoscope method. Run the engine (at idle only) with the rocker cover off. Poke a bit of rubber tube in your ear and point the other end at the top of each valve in turn. You should be able to identify which valves are noisy. Those are the ones to re-check and look at the condition of the rockers. Link to comment Share on other sites More sharing options...
Guppy916 Posted May 11, 2018 Author Report Share Posted May 11, 2018 As to the above but use a feeler gauge of the correct thickness Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 11, 2018 Report Share Posted May 11, 2018 we should cover tap-petty tap on twiddle day its a free house you can ask what you like on the day. if we can we will its easier to answer questions than pre empt what you all like to know Pete another old idea for noises is a nice big wooden handled screwdriver placed against zones of noise amazing what you hear not good on rockers or things like fans or you end up in AE to retrieve the driver ha ! and all 4 and 6cly rocker's ' have a tappet clearance spec. of 0.010" COLD + 0.25mm Link to comment Share on other sites More sharing options...

T.bailey Posted May 11, 2018 Report Share Posted May 11, 2018 I used a 0.010" (0.254mm) feeler. I have used a screwdriver as a stethoscope before without hurting myself (yet), but never heard of the hose pipe one, i'll have to give it a whirl this evening. I think it'd be best if I just take off and inspect the rocker assembly, that way I can see what I'm dealing with and check that the whole lot is sound and was torqued down properly.

Pete Lewis Posted May 11, 2018 Report Share Posted May 11, 2018 be careful the hose idea, you might be on the wrong forum its easy enough to reface the rockers they are not overly hard, you can leave the wear face intack but reduce any step so feelers get a better shot at measuring you can use a stone or whatever to follow the pad contour, if the shaft is worn you will soon see take a picture or sketch of the assembled shaft so you know where the left and right rockers and the springs all go Pete Link to comment Share on other sites More sharing options...
