Hello guys,
when I drive my puma a bit sharper than usually, I notice burned oil smell in cabin. today I checked engine if there is any wet oil mark and there really is a place in upper right corner of engine where oil seems to be leaking out. Any ideas what it might be? I just want to be prepared for how much it’ll cost me.
Thank you very much.
 
Just ordered Erling 026.570 gasket and erling 036.163 . Hope I’ts a good choice. Any opinions about quality? And are those items correct?
thank you for replies :)
 
I'm using Elringo on mine. Advised to put sealant too.
On mine, in a part that was missing a bit of sealant, started leaking so, I've done it again
 
applied rocker cover gasket, sealant. Still drinks oil... much less in comparsion with previous situation. Before 1L/1000km now approx 0,4L/1000km . Any ideas what should be checked? I have no oil marks on the ground or around rocker cover....
 
Look underneath with an inspection lamp at the sump. The 1.7 engines seem to love seeping oil out the sumps. The gaskets start seeping after about 10 years on all cars. It's a bit more tricky to replace the sump gaskets, but it can be done.

Also, get someone to rev the engine when it's warmed up, look at the exhaust for any blue smoke coming out either on rev, or when the rev is off and the car it going back down to normal idle. If there's blue smoke then it's burning the oil. New engine time.
 
Ok, next suspection points: the camshaft seals. You will need to tak the timinig belt cover down and have a look there. Also, you have two crankshaft seals. One is at the front of the engine (crankshaft pulley for the timing belt and in front of it the serpentine belt for the PS pump, A/C compressor and alternator). To replace it the timing belt will need going down.
The other is at the back of engine, the big one. It is beneath the flywheel necessating taking down the gearbox and then the flywheel.
I don't think the oilsump is leaking as it has no seal whatsoever and uses the sealant compound instead so it is very durable in that respect (no rubber there to fail with time).

That leaves the engine actually using oil. Open up the inlet manifold (take down the TB and tako out the IAT sensor out of inlet mani and have a look if they are covered in oil. If they are, have a look at the oil breather (black box) at the front of the engine, just above the thermostate housing. If it is full of oil, the return valve at the top of it is stuck open and the engine is pushing oil into inlet big time. First clean that really good and then source the inlet mani gasket (the thick one, it is unique to the 1.7 engine as it act as a spacer as well) and clean really good everything. I would suggest to do the same to MAF sensor and the TB as they will be covered in oil as well.

After that is done have a look at exhaust. Is the engine emitting blueish smoke? If only at liftoff the valve stem seals are gone. That in itself is not to much of a problem.
If your exhaust is blueish on power application, then piston rings are most probbaly worn. But to reassure you: I don't think I have EVER seen 1.7 engine emitting blue smoke and the biggest runner in terms of mileage was one with over 400.000 km on clock. It was working as sweet as ever. Just do all the seals and gaskets and you will be fine
 
Thanks for all your replies, will check this all as soon as possible. Are any of those additives to oil reasonable to buy, what about Liqui Moly Stop oil leak...? At least it's cheap and may solve this problem. If not, i'll continue with solving the problem standart way.

No, bad idea. Modern engines don't like them and a Puma's VCT likes them even less.

Follow Wild E. Coyote's advice above, starting with the oil breather, and see how it goes. Even if you did nothing that would be better than adding those additives and 0.4 litres of oil every 1,000 kms is not the end of the world, if the engine is otherwise running OK and not dropping oil on the ground.

Btw - did I mention adding oil additives is a really bad idea? :)
 
Ok ok I thought you'll not like it :D. And can level of oil be different when temperature is around -13 degrees? When I had oil on min. I pour in around 0,4 and it was 1mm under full. Manual says that it takes around 1L of oil to get it from min to max so where is the problem? and yesterday after 300Km it drops to almost min so it's kinda funny :D Will check it tommorow, guess it will remains the same as it was yesterday.
 
Today I tried to localize leaking again and I saw that on rear side of the engine approx in between center andright side are hoses and cables dirty from oil. Not at the top, Its nice and clean after changing rocker cover gasket. Anybody knows whats on rear side of engine descripted above? Fortunately no leaks on left side of engine.
 
Behind engine is the power steering pump that can develop a leak. BUT! it uses its own oil, not the engine oil. That is all there is behind engine (just to make clear: behind engine I am referring to as the part of engine facing to the cabin and to avoid any confusion, let's call it the exhaust side of engine.
So on exhaust side of engine there is power steering pump, exhaust manifold and catalytic converter and beneath it all driveshaft passing from the gearbox.
On inlet side of the engine, the one you are seeing when you open the bonnet, is inlet manifold, the breather hoses, the breather box with valve, the thermostate housing, electric starter and that's about it.

The only thing leaking from the exhaust side could be either rockercover gasket, or headgasket (but that would also leak the coolant as well).
 
Is it actually losing engine oil now? The powersteering fluid is located to the left as you open the bonnet, it's a little bottle. Keep an eye on the level, usually when these run low on fluid the pump goes noisy, you know when it's low on fluid. The Puma pipes are slightly more complicated and require more expensive pipes to other Ford's without A/C.
 
Yep, still leaking, no new oil marks anywhere so I guess I’ll be just refilling oil. Now its consumption is somewhere around half a litre per 1k km.
 
Well not leaking but eating I think. despite of I cannot see any weird smoke coming out of exhaust. Don’t know but but consumption like this is ok i think
 
Yesterday it was raining and I saw water streams with oil. And then I saw it. Oil marks on the ground... based on where they were its dripping from left side of engine when I open bonnet. Any ideas, can you direct me please?
Thank you very much guys.
 
Likely to be from the Camshaft seals or front crankshaft oil seal.
There is also a hex bolt screwed into the block behind the cambelt that has been known to work loose.
Despite other peoples comments about not using engine additives, the engine is nolonger in warranty and the product I am recommending works extremely well and won't damage your engine. It will take at least 250 miles to take full effect and you may have to use more than 1 tin . So buy 2 tins.

Stripping down the engine to do the seals and also to replace 16 valve stem seals is very costly and labour intensive . This will help and potentially the best £12 you will spend in a long time. :thumbs:
