had one go on mine ,some years back. took me ages to find it. lead resitances were good but it was burnt out at the spark plug lead end. will get worse if this is the problem.

borrow some

check your leads not breaking down under load. normally at spark plug end

not got head back on yet but hpefully every thing will be ok

yourstruly stuck it in the pipes to stop dirt getting in engine ,while it was out last ,for conversion from carbs to injection. what a 🙆🏻 well at least the problem found now,was pulling last of hair out not knowing what was wrong

took off head today as problem seems worse at first could see nothing wrong ,till i removed pressure reducing nonreturn valve in block. bingo piece of blue tissue stuck in valve. at last the real reason for problem, self inflicted. just hope thats the only piece ,dont want to strip whole engine.

how long before i cleaned first set went for a long run but still noisey beginin to think im a unlucky bastard

what is the best grade oil to use ,when doing searches seem to be mixed views thicker or thinner normally use mobil1 0/40 and never had any problems never used it this time because did not have enough at time of refill at present 10/40 standard oil have had tappets out again today and refitted some old ones in case i have a dodgy one or two but still no good the original ones that i removed about five of them are still soft, is this a matter of waiting for them to pump up or am i dreaming[wishing] could it be they still got some air trapped in them.

have had cover off again ,blown down oil galleries from head all seems ok ,cranked over engine loads of oil presure and what seems loads of oil in top of head. but still they rattle. some tappets in head do feel soft to touch is this normal or the problem. *confused* about to cut wrists have had enough now

tried a new sensor last night gauge reading more stable and lower than last one. but engine sounded worse in garage penty of oil returning to tank and under rocker cover oil filter just replaced with oil[plus this before gauge,so if it had blocked would i not have low oil pressure.] regards pete. i have read there is a oil pressure reducer in block under head that can fail ,could this be the problem

if engine running mega rich how quick can fuel contaminate the oil

oil at moment 10/40 cams QED mild ones Q42 springs standard oil pressure in oil gallery on side of block on tee piece with low loil pressure switch 25psi gauge vdo 0-5 bar sensor into AIM MXL digital dash

tappets are hydraulic have no valve clearance. is it worth me converting to solid tappets ,or am i just avoiding another problem with engine.
