Technical Oil / Water leak - headgasket ? Please look

there's no temp gauge in the sei...

On my way to work (20 miles) in the morning - the fan doesn't even come on.

On the way home it does come on about the last 3 miles. And that is only if in bad traffic....

So far there's no mayo in the coolant tank/ oil filler cap.

However I do think that the oil level has risen.

ahhh right, sorry thought this was for a cinq. :eek:

it makes it a little more difficult with u not havin a gauge, but has the organge temp warning light ever come on?

the fan will only kick in at 92 (i think) degrees, but as u have no temp gauge u cant really tell. as long as the warning light isnt comin on then it isnt overheating.

and if it isnt overheating, then u either have a leak, or the water is bein evaporated from somewhere (obvious i kno) maybe its time to get a compression test for the HG.

How much is a compression test going to cost me ?

fair one, so so its not overheating at all..... the fan is comin on properly (i guess it comes on, and then goes off again after a little bit?)

but your losing water somewhere?

got no idea how much a compression test will cost, but it should be able to tell u if the headgasket is in 1 piece.
 
Yes the fan goes on and then off after a couple of secs.

If it's not the head gasket then I have no Idea where all that water is going.

Since there is no sign of a leak on my driveway.

fair nuff.... so your therm is workin fine, the fan and switch are all fine.

but you have irratic idling and coolant loss.

does sound like the HG is on its last legs, but im not 100% on that to be honest :eek:
 
The headgasket can go between cylinders. When gas speeds are low at idle the compression can jump across the gap leading to poor idling. At higher engine speeds this is less obvious.

With the engine running, take a pair of insulated grips and remove the plug leads one at a time. If you remove a good one, the the engine may stall or at least try to stall. If you remove the bad one then there will be no difference to the running of the engine. At least it will give you astarting point.

well you can check if your headgasket is blown and leaking into the combustion side. fill up your expansion tank and bleed the system ensuring that no air is present, then fill the expansion tank up againt to the top, leave the cap off and start the car and take the revs to about 3000 rpm and if you see bubbles coming from the water in the expansion tank you know the gasket is blown bet the water jackets and the cylinders. if no sighns of oil in the water or water in the oil (milky colour oil) then your headgasket is ok.
i know that the welsh plug on the side of the engine at the water pump normally goes and it's hard to see the water leaking as it's behind the cover.

All this did was making nice fireworks (n)

removed one at the time & didn't make any difference what so ever.

Where the heck were the fireworks? There is something odd going on if you can remove leads and not hear any difference. You've got me well bamboozled now, sorry.

Cheers

Well I removed the leads one at the time. & sparks where coming out of the connections like crazy.

I did it to all 4 & it didn't make a difference to the idle. :confused:
 
Well at least your coil packs are working!! You did take the lead far enough away to stop the sparks. If the plugs were getting the spark then the experiment won't work. You need to get the plug cap away from the plug top.

Water level dropping but no obvious place to see it. I say H/G on it's way out.

Yes I did. Also tried disconnecting them at the other end.
Removed all spark plugs, checked them. Put them back in.

It;s still lumpy when starting it. But once the engine is warm it's running fine now.

Saying that yesterday it lost power. Top speed was 70 mph!


Still no sign of mayo...

I check the coolant level after every journey & there is always some coolant around the cap. (very small abount)

lumpy idling - check
loss of water - check
now got loss of power - check.

sounds like head gasket to me mate (n)

if there is a small ammount of coolant visable around the cap when u pop the bonnet then it isnt sealed properly.
 
this morning it was driving fine :confused:

no power loss.

If it is the H/G then it's time to whack a punto engine in :D
 
Ok I just went for a short drive in my lunch break.

It's now extremely "lumpy". Checked coolant level - went down again.

Still no sign of mayo. coolant still has it's nice blue colour.
No overheating
No warning lights
never stalled
& always starts first try in the morning


What's going on ?


I don't think it'll make the 20 mile journey home :( :bang:
 
water pump has been changed 4 k miles (6 months) ago.

and no sign of leaks on my driveway.
 
Update

Please have a look at this pic.

This seems to be the only place where there is water/oil.

Any Ideas ?


The idle is absolutely fine once the engine is warm.
