No compression cylinder 3

1st January 2011, 15:59

I stripped my head due to no anti freeze, i took all the valves out and found out that none of them where bent.
Today i have rebuilt the head back up with new oil seals, headgasket and full gasket set + cambelt, i've timed it up 100% perfect.

Its firing on 3, did a compression test as follows

Cylinder :

1 - 10 ( green )
2 - 9 ( red )
3 - 0 ( red )
4 - 8 ( red )

i havent adjusted the valve clearances as of yet, has anyone any ideas on what to try / test ?
Cheers

Is it 8 valve or 16 valve?

I'd check that a valve isn't staying open due incorrect valve clearance. Take the cam or rocker covers off to check

1st January 2011, 16:55

Why didnt you check the valve clearances before you asked us? Thats what it probably is! We like to help but thats just taking the pi55 with our time

If its not that it might be a valve thats bent but it looks straight to you.

I'd say Valves, Check them before you do anything else.

you need to grow up mate saying bout wasting our time when you couldn't even change ur cat and make a thread about it, that you couldn't even do up x2 10mm nut

any way will most likely be a slightly bent valve that you can't see, did you re-lap all the valves back in and did they all slide in and out and turn ok

The point of my post was to highlight and discuss silly design features of the Citroen Saxo. I didnt ask anyone how to do it. I remember the last time I put a cat on I had to use mole grips across the exhaust flanges.

Why the bolts can't be a little longer is beyond me. But instead of replying with ironic or critical comment [of Saxos] you suggest that I cant do 10mm bolts up when I so obviously can

Where did I say I was an expert?

The guy wrote on here asking for advice and I gave it.

He could at least have checked the clearances instead of just talking about it

1st January 2011, 20:10

The valves where re-grounded in with cutting paste
the reason i haven't tried to adjust the clearances is i wasnt sure how to and it was getting dark.
Is there a HOW TO for the clearances ?
none of the valves looked bent when i removed them and tested.

How did you remove them if you don't know how to check them?

I'm not having a go, just confused? Lol

1st January 2011, 20:12

its also a saxo vtr blacktop 99reg

1st January 2011, 20:13

removed them with a spring compressor lol, im a vauxhall mechanic by trade never touched a saxo in my life

the design of French cars is as it is if ya don't like it buy some jap crap or even better German,all cars have some issues with design, nothings going to be 100% perfect, the post about the cat on your car is stupid, and commenting on this chaps issue in the way you have makes you look retarded to me tbh, i have read multiple posts by yourself including the arguments you had last week on here about mechanics jobs being easy and unskilled then you post that

Unlike most 'mechanics' I will do the job without cocking it up and then not charge myself a fortune for the priviledge.

If you cant engage in wry philosphilcal discussion about car design, like Stu did. Then dont even bother with your retarded replies.

If customers dont question things and demand better then nothing will ever improve, but you are obviously too slow to realise that.

And I would like to reiterate that in the 30 or so times I have used a 'garage; in my life. They have cocked it up every single time, without exception. That is not my fault, and I did not want it to be so, I do not like hassle with garages.

The OP here didnt even bother to check valve clearances- and AMAZINGLY DOESNT KNOW HOW DO DESPITE HIM BEING A MECHANIC! Proves my point perfectly !

1st January 2011, 21:12

Mark 89. Thankyou so much for proving my point. You are a mechanic yet dont know how to set Saxo tappets! Lol.

Goodnight.

1st January 2011, 21:14

Id personally say the timing is out or the valves are bent.... It could be a few thing though

your an idiot,i havent come accross this type of engine before.
only asking for help you bellend.

1st January 2011, 21:51

i would check the valve clearance first you use a set of feeler blades and put them between the valve top and the rocker arm then adjust the accordingly, you did put the valves back where they came out of

when you ground the valves did you check the face of the valve aswell as the head, if they were bent i would imagine they would look fine on the head side but would only grind the part of the valve in contact with the head

1st January 2011, 22:07

Id check the valve clearences first , im not sure what they are set to on the TU engine , should find it somewhere on the Forum , turn the engine over and use the rule of 5 , if number 1 is on the valve overlap , number 4 will be full closed , so adjust that one , and so on

then after that , check all of the valve collets are seated right , then after that id try to see if the valves are lapped correctly - onwards from that , im stumped

1st January 2011, 23:06

Everyone arguing isn't helping the OP. Stop the arguing and get back on topic.

None of us know everything about the saxo and even if the OP is a vauxhall mechanic doesn't mean he is familiar with the saxo engines.

We help people with much more simple problems so to the OP - ignore the people calling you an idiot and good luck with getting the engine sorted.

I'm sure someone with good knowledge will post with some other suggestions soon.

Calling me an idiot? Setting tappets is the easiest job in the world. It makes no difference what make of car it is you idiot.

And you call yourself a 'mechanic' too!

Jeezus

Oh and your well thought out, polite comments help everyone don't they?

Any particular reason for you posting a message in here?

Anyway, back to the problem.. why did you have to change the head gasket in the first place? Did you have the head skimmed and pressure tested? Was it missing on cylinder 3 before you changed it? Thinking head might be cracked

I can't imagine the clearances would be that far out if they were OK when you started

turned out to be a worn follower, which isn't the easiest job in the world

Thanks mate, also to everyone that is helping.
im going to adjust the clearances now, test to make sure the piston rings haven't gone as well just out of curiosity.
will update on what i find

2nd January 2011, 13:28

Have you done a leak down test on the cylinders ? i mean bring them slowly up to compression to see about what position in the stroke its losing it ?

doing that in a minute, just done the clearances.

all exhaust where 0.40

the inlet i couldnt even get a 0.10 through,
would this be the cause ?

Could be...

Set them to spec and try it.

2nd January 2011, 15:23

if the inlets being held open on a compression stroke then it certainly could be

2nd January 2011, 15:32

cheers fellas all done now

10 ( green ) on all cylinders
starts 1st time no problems atall

once again thanks !

2nd January 2011, 15:42

Was it the inlet clearance then?

Worn followers are a common problem, and one that 'mechanics' should know all about. The mechanic on this thread doesnt even know how to set tappets when they are not worn. Then has to ask us amatuers to sort him out.

When I observe this irony I am suddenly the bad guy.

A Saxexperience to be sure. But defend your mechanics to your hearts content, just dont complain when they fuck your car up.

What a waste of our time.

2nd January 2011, 18:09

All the valves where moving freely, only one needed adjusting on cylinder 3.

Railroader, your a nobhead who hides behind a computer screen sitting on a forum all day building up e-points.
You need to get a life mate seriously.

2nd January 2011, 18:12

Oooo deary me... arguing isn't a good idea

glad you got it sorted mate
sorry but you'll fined there are some right tools on here but also a handfull willing to help you

It only takes one valve to cause a problem.

Funny how Ive been out all day then. And could hardly bring myself to bear looking in here- it was only out of curiosity to see the thread endings.

Wont be so often again either, the lunatics have taken over the asylum!

3rd January 2011, 17:44

Thread Locked.
Glad you got it sorted in the end, even with the distraction of railroader!
