#1: Tappets adjustment.. done it? Author: V9977, Location: Athens, GreecePosted: Sun Feb 26, 2012 4:41 am ---- The engine sounds somewhat rough and noisy at high rpm with ever so slight loss of torque.
Thinking of adjusting the tappets myself so any tips or info would be appreciated.
Also does the plastic cam-belt cover have to be taken-off to turn the engine while doing it?
Car has done 94000 Km, much of it in traffic so the engine will have rotated for a lot longer.
Thank you. Last edited by V9977 on Tue Oct 02, 2012 5:43 pm; edited 2 times in total

TU3 engine that the OP has uses shim's, it doesnt have hydraulic tappets.

Turn the engine from the crankshaft, so yes the cover has to come off, from what I can remember its only held on with 5 bolts. Unfortunatly I cant remember the adjustment gaps. Oh yeah, do them when the engine is cold, hope Im not teaching you to suck eggs !!!!
#6: Re: Tappets adjustment.. anyone done it? Author: V9977, Location: Athens, GreecePosted: Sun Feb 26, 2012 7:56 am ---- Thanks for replies.
Gaps are 0.4mm exhaust and 0.2mm inlet. Yes it's adjust when cold with this engine.
Good point on the spark plugs.
Will let everyone know if I manage to ruin the engine or made an improvement.
Done it and it's a different engine.
Forget modifications etc, this is extremely important and makes a massive difference.
1) Quieter, smoother engine.
2) Torque has shot-up between 1000 - 2500 rpm.
3) Higher top speed due to reduced growling above 3500 rpm.
4) Less fuel consumption
I highly recomend people do this, especialy after 60K miles.

#9: Re: Tappets adjustment.. anyone done it? [UPDATE] Author: SteveTDCi, Location: StamfordPosted: Sun Sep 30, 2012 4:10 am ---- In what order do you adjust the tappets on the 206, and which is cylinder 1 on the 206 is it the cam pulley end or se it work backwards like the injectors ?

Cylinder 1 is on the right looking at the engine from the front, opposite end of the cam-wheel.
This is a procedure which requires skill and repetative 'combing' untill the valves settle back down, say every 600 miles for at least 3-4 times (!)
The closer the tappet get's to the valve pins the quieter the engine but with less power/torque.
The further away you get (up to a point), more 'rasp' but better power and less fuel consumption.
I set at standard gap (0.20mm inlet / 0.40mm outlet) and live with some ping of one valve at idling.
The engine has to be stone-cold, preferably overnight. (even though Peugeot say minimum 2 hours).
It's certainly worth the effort, but if you're asking the adjusting order I would strongly recommend that you refrain for the time being, and thoroughly research the subject for the 206 TU3 lump before you even think of taking the cover off. www.peugeot206cc.co.uk/repair-206/
Good luck.

#12: Re: Tappets adjustment.. done it? Author: V9977, Location: Athens, GreecePosted: Thu Oct 04, 2012 4:39 am ---- 1) Jack-up the front-left wheel and stick it in 4th gear to turn-over the engine slowly, only forwards.
2) Mind the two spacers under the valve-cover, they stick to the top then fall off into the cam area.
3) Use gloves, and you must use a troque wrench at 9 Nm for tightening-up the lock-nuts,
otherwise subsequent adjustments are going to be a nightmare OR you'll end-up with a loose tappet which you don't want.
4) You must reset the auto adaptation by dis-connecting battery for half an hour so it can re-learn running parameters with the new adjustment.
5) Don't forget to dis-engage 4th gear before starting the car again..

#14: Re: Tappets adjustment.. done it? Author: MrBSI, Location: What's it to you? ? ?Posted: Thu Oct 04, 2012 9:43 am ---- Im doing mine on my TU3 tomorrow after work, should help make the engine a bit less noisy
#15: Re: Tappets adjustment.. done it? Author: SteveTDCi, Location: StamfordPosted: Thu Oct 04, 2012 1:13 pm ---- Ha ha, mine isn't too bad, first job for me is to get the air out the system
#16: Re: Tappets adjustment.. done it? Author: Harry, Location: StaffordPosted: Thu Oct 04, 2012 1:40 pm ---- I tried it a couple of months ago on a 1.1 saxo - still tapped like a bag of nails
#17: Re: Tappets adjustment.. done it? Author: SteveTDCi, Location: StamfordPosted: Thu Oct 04, 2012 5:37 pm ---- Never mind just crank the radio up !

Maybe they were neglected for too many miles.
But the point is not to make it quieter. (That's what I thought too at first)
It's to get better, smoother running overall of the engine and making it last longer, with more power and less fuel consumption. There is no-way you can do this properly just in one stage.
You have to keep at it 3-4 times over a period of time so the valve-seats re-form and the whole setup settles-down.
Also, unless you reset the adaptation every time, the ECU can't take the new setting into account. This can lead to big apparent problems straight-away with un-even idle, hesitation etc.
#19: Re: Tappets adjustment.. done it? Author: Harry, Location: StaffordPosted: Fri Oct 05, 2012 9:08 am ---- It's likely - to be fair I never drove it afterwards just ended up scrapping it did my head in long story short
Don't plan on owning a car with adjustable tappets again though
#20: Re: Tappets adjustment.. done it? Author: MrBSI, Location: What's it to you? ? ?Posted: Fri Oct 05, 2012 9:59 am ---- Well I checked my tappets today, its done nearly 90k miles & there spot on NO ADJUSTMENT REQUIRED
Inside of the rocker cover & the deflector plate could do with a visit to the degreasing tank but thats a job for another day, ill also save the new gasket till then

Wise move to leave them alone if gaps look OK.
How long did you leave the engine to cool?

Yeah, they all measured up fine with the feeler blades so left them alone.
Ill take the rocker cover of & clean it & the deflector plate in the degreasing tank at work then refit it with the new gasket in a couple of weeks.
#23: Re: Tappets adjustment.. done it? Author: V9977, Location: Athens, GreecePosted: Fri Oct 05, 2012 1:41 pm ---- This must be a result of good maintainance and OK driving.
Good to hear all is good.
#24: Re: Tappets adjustment.. done it? Author: MrBSI, Location: What's it to you? ? ?Posted: Fri Oct 05, 2012 1:46 pm ---- You can also turn the engine over with the spark plugs removed by just operating the powersteering pump pulley, it all turns over easy enough.
