You wouldn't need a new bottom end, new oversized pistons and rings though

i imagine it would work out much cheaper to get a new bottom end though?

I'd stick with what you knew was good to be honest and bigger bore generally = more power

When you buy new rings Martin, you should put them in the bores before they go on the pistons,
the gap in the ring should be measured with feeler gauges!! its been a long time since I did a set
so can`t remember the measurements. If the gap is two small it needs filing out, so when the ring
expands, it doesn`t shatter.
When putting the rings on the piston, correct me if I`m wrong= two compression rings, one scraper ring
and an oil ring at the bottom thats made up of three, first ring on! move the gap on the next 1/3 round
the piston from it and so on

That's a good point if you haven't done that but I'd assume you have

yeah i moved the rings round so the gaps wasn't lined up together. wasn't aware you had to check with the feeler gauge i just assumed you put them in as they were the right ones for the car.

Just had a quick read through some of this thread, Cracking car mate
Some hard work has went into this, I done something similar with the servo pipe to powerbox on mine. What exhaust manifold you using on your motor?

Yea, not to worry mate, they make one size ring for +10,+20&+30 thou
don`t think for one minute you took to much out with honer or glacier breaker as
they were called back in my day
got some work on martin, but all is not lost

Decided not to strip it down, changed the oil to Motorsport running in oil insured it proper and I'm gonna see how it goes. Hopefully it will bed in. Still overfuelling like mad for no reason though.
Got two new dials coming in soon, just making up the holder then it's off to get flocked and hopefully into the car soon. Pics to follow

there are at two seperate occasions. i thought the O2 sensor was playing up as it goes up the scale very quickly and quickly changes from lean to rich and back, but i understand this is normal?

Yes it's normal for an 02 sensor to switch from lean to rich as it makes adjustments to get the fuelling right and lambda to 1

as some of you know ive been having some serious problems since i rebuilt my X16XE . blue smoke, over fueling etc...
piston rings and valve stem seals have been done but still blue smoke on startup and under load.
took the head off again today to replace with a recon one and this is what i found on the pistons.
the top lip of the bores have a burnt mark around them, but that's just the top, not the whole bore. no scoring on the bores or anything. valves are just as black if not worse.
rings or stem seals?

Now you've got it stripped down this far Martin, you might as well drop the sump
and check ring's mate, always best when it's this far! just in case.
By the way, great work mate, keep at it, you'll enjoy it when its done

Smoke on start up will be the valve stem seals Martin. They can cause it to smoke under load at times as well.
Would it puff out a bit of smoke when pulling away after waiting at traffic lights etc? Would it start to smoke on idle if you left it idling?

Wouldn't say it would smoke at lights unless I put my foot down and I havent noticed it smoking if I leave it running I

`25/7
new head
inlet
in the car
and done
changed the head over with a recon one to see if it was infact the head at fault. with the old head i had a slight hunting on tick-over. put the new head on and now its shaking and popping all over the place. you can physically feel yourself move in the car!. took the belt off again tonight just to double check it was timed correctly which is was , but its still the same.
cant see any leaks on hoses, put a load of sealant around the inlet just incase and still no change. No eml either so ive lost patience with again! :@
had the bloody thing out so many times, i really cannot see what could be wrong.
anyone have any other suggestions as this is really pissing me and my dad off haha and mr sledge hammer might meet the engine some time soon

Hi Martin, New problems then! have you checked the HT leads are on correctly
and make sure your cam and crank sensor's are plugged into the correct!.
Also Martin check your Knock sensor under the inlet manifold mate then if all these fail
get back to me.

Cheers Daine ill have a look at all that an report back ASAP. What I did notice was one of yhe stumpy nuts that hold on the cam sensor wouldn't tighten, although it doesnt move away from the inner casing maybe the cam sensor could be slightly off? Feels lumpy like its running updated cams and you can see the engine rock back and forth all the time
