Adjusting valve clearance on a Fiesta
mackie - 13/8/04 at 11:22 AM

I'm about to attempt to service my girlfriends J reg Fiesta 999cc (or is it 998cc) banger. I'm not sure which exact engine it in but it's not the HCS but it is Kent-like.
I think I should probably look at the valve clearances (along with putting see-thru oil in it )
My question is, how do I check and how do I adjust them? This is something I've never done before.
I'm guess someone can give me some clues since it can't be that different to doing it on an Xflow.

Cheers,

Mackie.

If so it is most likely a Valencia engine! Let me know and I'll have a look for the procedure!

If you could let me know (2u2) the reg number I might be able to narrow it down

Donners,

It does look rather like that. It's a 1l rather than a 900 or 1.1. I'll u2u you the reg asap.

Seems like the Ford TIS doesn't go back as far as that. I can get part nos etc through microcat, but no procedures! I can email you a procedure for 1.25 zetec if that helps!!??

Sorry

mackie,you know how to adjust tappets?do one cylinder at a time(turn engine till inlet valve closes and add a few degrees for luck,feeler gauge between rocker and valve stem,11mm socket on adjusting bolt till it just nips feeler,easy peasy

What you just said does make sense, I've just never done it before. I'll whip off the rocker cover and have a looksee. It does sounds fairly simple.
How would you suggest turning the engine? Leave it in gear and turn the front wheels?

If you are going to do that, taking the plugs out makes life easier.

My MK1 Fiesta 1.1 used to 'tick' before AND after adjusting the tappets.

I think it was part of the design

I think it's meant to, to a point.
Actually my girlfriend's car isn't that bad but I thought I'd at least check them as a matter of course. It's just one of those sewing machine engines I guess


marktigere1 - 13/8/04 at 02:52 PM

They are a bit like a sewing machine.

Always liked the induction noise they made.

Mind you, engine did 100,000 miles with me and the bodywork finally gave up at 158,000

Miss its simplicity as well.

Cheers

Did you find it drank a lot of oil?


marktigere1 - 13/8/04 at 03:34 PM

Not really no.

Only problems I did notice on the oil front was on short journeys. Used to get loads of the white mayo in the breather/oil fill bung.

With long journeys I never had a problem.

Only let me down once when I failed to change the water pump in time. It failed at 70mph on the A1. (My spare was on the back seat as it had been making a noise for several weeks.) Totally my fault not the engine

jack one front wheel off the ground ,put it in top gear and turn the wheel,tis easier with plugs oot


mackie - 13/8/04 at 03:44 PM

If I can turn a Rover V8 with the plugs in with by bare hands on the flywheel I think I can manage a piddly little fiesta engine

Thanks for the advice all.

PS. I wondered what the crud in the filler was... actually... what *is* it?


marktigere1 - 13/8/04 at 03:59 PM

Its an emulsion formed when Oil and water mix.

The water comes from condensation in the engine on short journeys. Long journeys and the water just evaporates.

Cheers

You learn something new every day
My girlfriend tends to use it on mostly short runs which probably isn't so good but since I can get another car for next to nowt I don't really mind if it's not treated brilliantly.

Valve on the rock. is the way.

turn engine until inlet & exhaust on a cylinder are just between closing exhaust & opening inlet, then adjust opposing cylinder tappets ie 1 rocking adjust 4, 2 rocking adjust 3, 3 rocking adjust 2, 4 rocking adjust 1.

hope this helps.

enjoy.


stephen_gusterson - 15/8/04 at 10:52 AM

rule of nine isnt it? if 4 is fully open adjust 5, if 8 then adjust 1....

afair


I had a (old git anecdote coming on here) 1978 fiesta 950 van that I bought of my company in 1980 with 24k on it for 510 quid (bargain even at the time!)

I took it to 95,000 mostly motorway miles. It was still on the same (barely legal) tires - honest! Clutch was on way out.

Only thing that went wrong was a crack between two valve seats, that was cured in a day by taking it to a shop where they welded it and put in valve inserts and lapped em in for me.

At the moment I'm having the much more mundane problem of getting the damn oil filter off. I might have to swallow my pride and just get a garage to do it as I can't budge it.


Browser - 15/8/04 at 12:58 PM

Put a drip tray under it, hammer a large (i.e. non-bendy/hefty) screwdriver through it and unscrew it that way Does work, had to do it myself a few times


Peteff - 15/8/04 at 03:14 PM

Get a strap wrench you tight git . £1.99 on most car boots round here.


mackie - 15/8/04 at 03:51 PM

Tried the strap wrench but there's not enough room to really move it. Will try the screwdriver technique

Rule of nine only works on 1342 engines, the kent/valencia/ECS engines are 1243(?).

JGG has got for these engines
