have you checked timing? is there any chance you could have got it a tiny bit out? even just the ignitionn timing could cause it to 'pink'

did you adjust the tappets when the engine is in the correct position?
A simple way is the "rule of 9"
turn over engine till no1 is going down when it has reached the bottom no8 is the one to adjust, then same with no2 down adjust no7 etc
jack up a front wheel and put the car in gear and rotate the wheel to turn the engine. even easier with the spark plugs out.
make sure you have the correct clearances for your engine and are adjusting the correct valve, ie exhaust and inlet. if you look at the manifolds relative to the valves you should be able to see which is which

the haynes manual settings are perfect and don't take valve train wear into consideration, just give them a tighten up until its quiet. pain in the ![](http://www.wired.com/images_blogs/underwire/2009/11/fox_60.jpg) doing it but needs to be done.

Firstly, double check that you've adjusted them correctly, rule of nine means numbering the valves 1-8 left-right. turn the engine over until one of the rockers is all the way down and just about to start coming back up. This may be easier with a socket and bar on the bottom pulley with the plugs out than rocking the car as you get a bit more control. If the rocker that's down is say for example 6, then 9 - 6 = 3, so you'd adjust rocker 3. As has been said, make sure that you identify whether it's ex or inlet and use the corresponding measurement. The 'slipping in without nipping' means that you should be able to slide the feeler gauge backwards and forwards through the gap with out any real force but at the same time if you grab the rocker with the feeler gauge in the gap and move it up and down you shouldn't be able to feel a click which would indicate a gap. Mark the ones you have adjusted with a blob of tippex or paint or something so that you don't have to do them twice or miss any. If the gaps all check out right, run it (very briefly) with the rocker cover off to check that they're getting oil. What I've found on the later versions of these engines, Mk4 Escorts and the like is that all the black crud on the inside of the rocker cover and rocker rail acts as sound deadening, when it's cleaned off the noise from the tappets seems to be amplified by a clean rocker cover. Hope this makes sense and you get it a touch quieter.

silly thought which just crossed my mind, you are using the correct feeler gauges, ie metric not imperial?

Have you got the right Haynes manual. The OHV Fiesta engine looks identical as they went along, but the inlet/valve orders changed. You may have got your exhaust/inlet clearances mixed up.

If you don't know what feeler gauges you've got then how do you know what you're adjusting the tappets to? ![???](//storage.proboards.com/forum/images/smiley/huh.png)

1989 Peugeot 205. You know, the one that was parked in a ditch on the campsite at RRG'17... the glass is always full. but the ratio of air to water may vary.

just run it for abit, youl have to check them a few times before they're spot on. i had to do mine and they were a pain

when you had the head apart did you keep everything in order. for example no.1 inlet valve with no.1 push rod, spring, collets etc and so on. if not then that may explain why you are having difficulty in getting them right.

HI MATE DID YOU CHECK THE ROCKERS FOR WEAR. IE WHERE THE ROCKER PUSHES ON THE VALVE STEM FOR LIKE A HOLE OR GROVE (HALF MOON SHAPE)IN THE ROCKER. IF IT HAS THESE YOU CAN GRIND THEM OUT USING A OIL STONE OR PIECE OF OLD GRINDING WHEEL. JUST RUB IT OVER UNTIL YOU CANT SEE THE WEAR ANY MORE AND MAKE SURE YOU FOLLOW THE CONTORS OF THE ROCKER. I HAVE HAD A FEW CARS WITH VELENCA ENGINES IN AND HAD TO DO IT TO THEM ALL. HOPE THIS WORKS IF THIS AINT CLEAR JUST ASK AND ILL TRY AND EXPLAIN BETTER

^^ probably not! Asking for trouble doing that if you ask me, especially if they've been heat treated! Just make sure you're adjusting for the bit that is contacting the valve. These things wear so its very easy to adjust for the whole width of the rocket, when really the bit in contact in the middle has worn, thus you think you've set it right, but actually theres a larger gap due to the uneven wear. Its a pain but you can do it by using the tip of the feeler gauge. If you can't get it right fiddling like that, find some better condition rockers, they're easy to replace and pretty common (I used to have a box till I stopped using xflows) - or just turn it down till its quiet, its a xflow, they're pretty unbreakable ![;)](//storage.proboards.com/forum/images/smiley/wink.png) edit - just remembered, sometimes the rockers don't seat back properly when the gap is big, so make sure the rocker is contacting the pushrod correctly, and the rod is seated in the tappet - give the rocker a wiggle (push down onto push rod) before adjusting it basically ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)

Are a set of new rockers too dear to your pocketbook, Ande?

Valves too then. It isn't a huge job to replace valves, and they're cheap as chips.
Rockers are around 64.00 set here, and valves the same. For new ones.

Your rockers are probably worn. If you look at the underside of the pad that pushes the valve open you'll probably see that the top of the valve has worn a groove into the surface. Basically, when you set your clearances the feeler gauge is wider than than this groove and you get a false setting. The answer is to get a dremel or a sharp pair of snips and narrow the feeler gauge down so that it fits in the groove rather than across it. Just make sure you deburr the edge with some wet and dry paper. Old trick, not a lot of people know it ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)

Just gotta sort out my wobbling at high speed now,and I got a clunk coming from the passenger side, sometimes just the jerk from the clutch when pulling off will cause it to clunk, I just can't think of anything down there that would clunk. All Fiestas wobble at speed. Nah, it's probably a wheel out of balance ;D The clunk is (I think) the bottom engine mount. Look under the front of the car at the bottom of the engine and somewhere (I can't quite remember where) there is a big eff off bolt which is a lower engine mount or an engine steady or something. Pretty sure it's at the front. The bush perishes and it clunks. You can sometimes get around it by tightening it up a bit, you'll need a big mofo bar to do this and crank some serious shizzle out of it.

If you set them too tight the valves won't completely seal when things warm up and expand. In the short term, it'll misfire and lose power when it gets warm. If you carry on driving, you could overheat the valve because it'll not be cooled by sitting against the head for 50% of the time.
