Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Non-CB500 related: Car (Fiesta) problem...

Post by ceejay on Wed 02 Nov 2016, 9:16 am

Sorry I have to post this here but car forums seem... well pretty useless (I've tried asking this in a 6000 person Mk5 Fiesta forum and cant get an answer but if I wanted to fit a body kit, lower it etc, there'd be plenty of experts). Possibly there is someone with knowledge of Fords here?

I've got a 1.25 2001 Fiesta with an oil leak. I'm trying to identify that but first I'm trying to figure out what engine I have and I'm even struggling with that! You'd think working out what engine you have on one of the most popular cars out there would be simple...

The problem is (I think) Ford used slightly different 1.25 Zetec engines in the car during the same period. Haynes covers one and I have the other. Originally I thought it was just the air box location that was different but as I've gone to check valve clearances the tappets don't seem shimmed like they do in Haynes... so now I'm wondering what else is different... e.g. are the torque numbers in Haynes also correct for my car if I start removing the camshafts to find this leak (could be camshaft seal)? 

Anyway some pictures of the different engines.

1.25 Zetec in Haynes:



not so clean 1.25 Zetec in Mine:



Under the rocker cover in mine. Could there be shims underneath like the CB500 or are they hydraulic tappets?



Also if anyone can recommend a car forum where people are more interested in fixing mechanical problems rather than modifying the look of the car it'd be much appreciated Very Happy

That engine looks very clean...it must be low mileage engine, i am in process of buying a 2003 fiesta(for the wife) but it has 1.299 engine.... if the car is low miles and its running well i leave it alone.... ive a peugeot 306 straight diesel(non turbo) with 237k miles and its running well... engine never been opened... all engines leak oil as the oil seal perish over time.... oil treatment first see if it seal leak...maybe a ford forum....honest john ect...

Hi and seconded, I'd not be taking it apart either. If its not dripping and needing a top up each drive maybe best left.
Oil leaks mean different things to different people. I've a '99 Astra 1.6 8v, 133k, its my van of all trades. It has an oil leak due to perishing head gasket probably, it weeps rather than leaks so no attention until next service.

Btw those 1905cc straight diesel lumps do go on, I had a bx and did 191000, engine unopened before it got hit n run written off.

The very top photo is not mine, just a stock photo, the other 2 are of my car, 105,000 miles. The oil is dripping underneath the engine and coming from somewhere above the head gasket although not drastically and the engine doesn't need a topping up much but I figured it's only going to get worse. The car is not worth any money and I was thinking it might last longer if I fix it than if I didn't. I've already had to replace the rocker cover gasket in the past as that was leaking (rocker cover made of plastic!) but now there is a leak from somewhere else.

I guess the main thing I was hoping for initially was whether someone by chance happens to know whether those tappets are hydraulic or not.

I think those 1.3 non-zetec engines are a different beast again but supposedly also capable of big miles

I think the top pic is from a fiesta where Zetec is the trim level whereas you have a Zetec SE (sometimes called a Zetec S or Sigma) engine (confused yet?). Some Mazdas share the engine as they had a hand in the development along with Yamaha.

A quick Google found me this thread on a Ford forum which points towards you having hydraulic tappets.

Cheers for that, I'll assume they're hydraulic for now. At least I don't need to adjust them then!

Yes they use the Zetec name for a trim level too but that wasn't confusing enough for Ford here because with Fiestas of that age you could only get the zetec trim level on a 1.6 meaning these engines are actually both 1.25 zetecs that are different from each other... but very similar! Possibly even one having shims and one hydraulic tappets could be the extent of the differences.

Anyways Looks like I will have to get in there anyway to sort this leak...

Hmm I wonder if that pic is of a 1.0 or 1.3 Zetec-Rocam instead of your 1.25 SE.

Out of interest. Does the haynes show it as a SOHC or DOHC? (Yours is DOHC unlike the variant that started life in an anglia!)

True, but I wouldn't beat yourself up if you can't find/fix the problem; I suspect as long as you keep topping it up it will be fine.  The main problem will be if you don't notice it's got low...

The plastic rocker cover is to reduce the weight/cost of the engine - it's a non-stressed part, so plastic all the way ;)

I don't know too much about fiestas so I can't really help in any sensible way, but I hope you get to the bottom of it.

Haynes has three sections 1 for zetec engines, 1 for the Anglia ('endura') engine and 1 for the diesel. What confuses me more with the Haynes is that on the airbox section it mentions that on later zetec models the airbox could be located on the engine (like mine) as oppose to the left of the engine (like the other photo) but then there is no mention of the tappets being different which they clearly are when I look under the rocker cover and compare that to what should be there in the zetec section in the Haynes! Ohwell, looks like I may to lose the timing to replace some belts anyway so I'll find out for sure when I have a proper look in there.... Got someone on a Ford forum trying to tell me they are under bucket shims like the CB500 now but not sure about that given the link you found... Will be easier if I just take it apart I think : )

Just an observation. I worked on a neighbours car a few years ago - a CVH engined Escort (awful machine!!) which was making tapetty noises. The CVH tappets were hydraulic and when I stripped the top of the engine ( horrible job, as I was used to simple in-line pushrod stuff ) the problem turned out to be a small piece of crap blocking a vent hole on one of the tappets so it didn't adjust correctly. Blow clean, reassemble, problem solved. After lots of pain !!!
As an aside, most modern Fords are hydraulic tappets. The only exception that I am aware of is the Mk1 Focus ST170. The bread and butter stuff tends to be all hydraulic.
