Hi all ! . Got myself a Panda, that has developed a tapping noise for first 5Mins or so from cold. Oil change made no difference, 60k.
Could anyone direct me to any threads relating to this issue or ideas? As I'm a newbie, first fiat owner as well, any assistance will be appreciated!! Many thanks
 
If it goes away when warm then chances are it’s a sticking hydraulic tappet and not too much to worry about, sometimes a can of engine flush can sort them out but if you’ve just done an oil change you might just have to put up with it for a bit. I had a car once that used to do it on a regular basis and i just used to start it, let it tick over for 10 seconds, then stop and restart it and it’d be silent for the day then

I believe the 1.1 and 1.2 FIRE never used hydraulic tappets? They are solid with shims to adjust clearances. I'm very happy to be corrected though if I'm wrong. The 1.1 and 1.2 are well known for tapping noises briefly - very briefly - on cold start due to the oil supply taking a few seconds to get up to the top of the engine to lube the followers. Our 2010 1.2 60hp does it but it's literally just seconds and I've heard others doing likewise.

What year is your car Rowley? Early versions had an oil supply pipe which ran along beside the cam with holes in it to direct oil onto the lobes. Later engines incorporated the oil supply into the cam cover itself. Maybe this oil supply is blocked or partially blocked? I've seen the early engines with the separate pipe with some of the holes blocked. The early engines are quite easy to identify as they have a square shaped rubber oil filler cap. I can imagine that if the pipe was blocked or maybe partially blocked, then the tappets would rattle until enough oil spilled out from the cam journal bearings to lube the lobes and tappet buckets? Just a thought.

Any chance of posting a recording of the noise?
 
Thanks for the rapid response!.
58 plate, round oil filler cap. Model active eco.
This morning no noise started and ran fine.
However 5 hours later started the car again and rattle/clacky for minute or so, both times engine was cold. It does sound like top of the engine and oil not being present does make sense.
Will record engine sound next time she plays up lol. I will give the 10 seconds a go
Again many thanks!!!

Worth a go, although I’d trust what Jock said over me, as he’s a trained mechanic and i’m what I’d describe as a tinkerer! Either way though doesn’t sound too serious 😉

58 plate so 2008/9? with round filler cap so no spray bar it'll have the oilways in the cam cover I think? I've not come across one of them with a blockage myself. One thought does occur. The oils supply drillings between the cover and cam journal housings are sealed with rubber O rings which fit in grooves in the cam cover. If it's been assembled with no O rings the oil will leak at this join instead of going to the cam? Just wondering. Maybe not very likely?

Don't put yourself down man. It might well be a sticky tappet, just not a hydraulic one :unsure: ? It's strange that it's ticking for so long, usually they just do it for a few seconds. If our friend manages to upload a recording of the noise I'll be listening to it very carefully.

Yes, be a lot easier to diagnose if we can hear it 👍
 
Hi My Panda 1.2 Eco 2010 has now done over 270000 miles ( Guestimate as odometer stopped at 248548.477 miles (400K kilometres ))and is now showing as - - - - ) - tappets noisy for a minute or so on start up and once oil circulates much quieter - otherwise what a wonderful little motor , having never broken down, however just replaced with third clutch now! Note If disconnect battery - resets to 248548.0 miles and then after half a mile onto - - - - miles

Ignore my comment on doing Beckies VVT. I see it wont have this. Probably better for it most of the time!!
 
Hi , started the car this morning and quiet again, maybe in the background, made a vid anyway, but when it gets noisy again I will record it.
Hello loftus, good to hear your car is still running well even with the noise!
Clutch going is a pain though, not a lot left on mine I feel. Guess it would not be a Fiat without it little quirks! lol.

You just beat me to the punch. You're right, no VVT on Becky. My boy's 2012 Punto 1.4 had it though. Unfortunately "kamikaze woman" managed to "T" bone him and write the car off so I can't experiment. It always seemed sluggish though compared to Becky so it would have been very interesting to have had a fiddle with it. It occurs to me that cleaning this out might be one of the first things to do when buying a used one with VVT. Would you believe, we'd just put a clutch and slave/master cylinder into the before she "attacked" him. Ah well, c'est la vie.
 
Should I be seeing oil splashing around?
No not a lot. I forgot to fit the cap on my daughters car a few weeks ago. She set off on a weeks holiday and returned 800 miles later. When I went to check the oil, I realised my error!! Thankfully the car was still fill of oil and the amount lost over the engine was minute. I put my wifes cap on cleaned it up and said nought!! New cap for the wifes car from S4P was under £10 so I got away with it.

Lucky! Dive wise it's nippy , surprised considering only 1.1 !!. Most fun little car I've ever owned 😃

Aye, think I'd have got away with that too if it was my daughter. I don't think either she or her husband ever open their bonnets. She gets away with it because she does so few miles in their wee Skoda Citigo and hubby drives an electric Enyaq - so no point in opening his bonnet anyway!

I know at some point the cover is going to have to come off, just for piece of mind. I do know the previous owner let the service lapse, and the car was practically garaged for a couple of years?
Maybe I should have oil flushed it first as suggested?
 
Evening, not a good video, think she has stage fright ! . Couple of taps seems to be less than before? Has been much louder! , and lasted longer? . Will post better if the car allows lol.

That doesn't sound like the typical startup tappet noise I've heard on these engines. I'm reluctant to take a guess at what it might be without being able to listen properly to it "in the flesh" but, I'm sorry to say, I don't like the sound of it very much. Listening in the oil filler isn't very helpful, I think the mic is struggling with it. Because it's an easy thing to do I'd be tempted to take the cam cover off and closely inspect the cam lobes for scoring/damage and also the cam followers. It's always difficult to be sure based on a recorded sound like this. Doesn't sound like big ends but it definitely doesn't sound "right". Could it be piston slap? Probably not? My money's on something to do with cam and or followers. Do let us know when you find out please.

Edit. It's about the right frequency to be just one cam follower involved, don't you think folks? I can also hear the typical "worn bearing noise" in the background which many of us have mentioned before - unlikely to be related to the tapping.
