Hi there,

My mate f**ked up my car and is sitting next to me trying to figure out if all 1.6 Zetec-SE cylinder heads are the same!!!

Basically the timing belt replacement went tits up and I've got 16 nicely nackered valves and God knows what else!

We found a Zetec SE engine at a local scrapyard but its a FYDA/1 variant. I have the FYDB/1. What we need to find out ASAP is if they can be interchanged?

Thanks for any help guys!

Jack

 

Hope you understand it.. i have a translator. my english is not so good.

The bassis as well is the same!
Just because another computer is to sit with other environmentally Eissen engine has a different engine code

 

Thanks for your attempt - not quite sure I'm getting it.. anyone else got any ideas? Save us taking them both off and finding they dont fit?

Cheers

Jack

 

if you've got bent valves you will have damage to the pistons and or bores. depending on the severity of the damage you may need a new bottom end too.

take the head off first and assess the damage. post pics up too so others can help advise how bad the damage is.

i'm not sure about interchangability of heads so personally i'd be after an identical one. wouldnt want any suprises of incapatability for whatever reason, sensors may be different for example.

 

ps, hope your giving your mate a hard time about this, timing belt changes are easy!!

he may well be getting a lot of stick for a while

 

Yeah mate it was a fun week. Basically a bought a fairly nice 2001 Focus and thought I'd just give it a full service. Mileage was at 75K so wanted to do timing belt too.

My mate restores Porsche and TVR engines so I thought it would be a doddle! (So did he). After the timing going tits up (but it still running - just like a dog) we eventually did timing again and it sorted it. Second time round learned that its best to use a timing pin! DOH! Went for a test drive and drove like a dream - then as he pulled in to the workshop and had it idling, something slipped and it conked out. He said two of the valves are fairly damaged and other ones have been hit too. Slight mark on piston heads but because it was just idling I guess it doesnt do as much damage as regular driving.

We're sourcing a new head or thinking about just replacing the valves (would this suffice?) - but need to find out compatibility!

Of course he's paying for all of this Just annoying not having a car!

 

Phase 1 and 2 engines are different but heads can be changed. Do they both have a plastic cam cover or does one have a metal one?

The valves are different in them though so you cant swap over them over.

If you want any help on the SE or need any parts see this man: www.shawspeed.com

 

I know they're both SE's and I think they're both Plastic cam covers. However the variant is different - but I'm not entirely sure what the variant means.

Thanks for that link.

 

If it is any help, when the 1.6 silver top in my old V plate focus went bang, I stuck in a 1.6 black top from a 2003 car. Used the loom off of the silver top but apart from that it went straight in. So I imagine it is all pretty much the same!

 

Was that the entire engine or just the head? Just looking to swap the head! Just thought Zetec SE head was something a little bit different?

 

It was the complete engine, but all worked fine. Only was to tell really is to whip your head off and compare it to the other one. Really don't see why it would be different though!

 

timing kit is only a few quid from motor factors and makes the job a lot easier, only way to do it imho on those engines, unless you use a load of dial guages and know the specs of the cams.

if the pistons are only slightly marked they should be fine. if just the valves are bent and theres no damage to valve seats and guides then you could just replace the valves that made contact with the pistons. may aswell put new valve stem seals in too. cost wise it may be no more expensive to get a good salvaged head which would save dismantling the head.

unfortunately these things happen. hopefully any differences in head design are minimal and not going to affect anything as Rich170 has proven the black top and silvertop se's are interchangable in the focus so you may well be able to use the silvertop head.

good luck in getting the porblem solved. when it comes to timing it back up use the timing kit with the pin and bar for the cams. then once fitted and tensioned you can remove the bar and pin, turn the engine over a few times, refit the pin and then when you reach tdc and the crank stops as it hits the pin you can check if you can get the bar back in the cams. if you can timing is spot on! oh and remove the spark plugs when turning over by hand, makes it soooooo much easier though i'm sure your mate knows this.

good luck with it, i hate being without wheels tooo

 

Silver top and blacktop heads are the same for the 1.6. I believe the only differences are in the bottom end and the cam cover. Mounts and everything are also the same.

 

Thanks guys for this! Let's hope we can get the timing right first time !

 

Not quite true, the two engine vary slightly, mainly due to the lifters if I recall correctly.

There is a myth that the Phase 2 (Or blacktops from earlier cars 2001 onwards) are stronger than Phase 1 (Silver tops Pre 2001 engines).

As for heads being interchangable, I sold my cammed P2 head to a guy with a P1 engine, and he has had no issues with it, so would say you would be ok unless using one from the Ro-CAM VCT engines, as I'm not sure if they are cross compatable.

 

I seem to recall the above from another discussion before.

If they are both plastic cover they will be the same. Or if you want to just replace the valves call the guy on the link I posted. He might well have some 2nd hand ones about too.

Wrong, Phase 1 heads have longer valves and different style of buckets as said.

 

I meant they're the same as they'll fit, not that every intricate detail is identical.

 

But they aren't the same are they? :P

It's all in the detail.

 

His mate managed to fuck up doing a timing belt, I doubt he knows/cares about valve size

 

I'd hope he would, because if he did come to rebuild the head and use the valves out of a phase 1 head because you said they 'are the same' when actually they aren't he's come to the wrong place for advice.

 

He's already said he's going to swap the whole head.

Ok, I didn't say the valves etc. were different, and took the easy route. Come shoot me for my crimes...

 

Ha ha ! Calm down guys! I've ordered a replacement refurb head for 300+ quid now. Good job I aint paying for it...althought it looks like I'm paying for it in other ways as it was guaranteed to be here at 12 o clock today and it never showed. I've been promised by Monday but I'm not holding my breath. Bet it will be the wrong head in the end!

 

I think the problem he had lied in the fact the pulley aint keyed? WTF is that about?

We didnt have a timing pin first time either ...

 

its to save money mate as theres 2 machining processes, one in the cam and one in the pulley, and the manufacture of a woodruff key.

theres no need imho to slacken off the cam pulleys when doing a belt change on these engines! timing pin keeps the crank set and the bar in the back of the cams keeps them set. once its turn the engine over a few times, refit the crank pin and rotate the crank till it contacts the pin. if you can slot (or near as makes no difference) the bar back in the cams its timed up perfectly!

 

Thanks for that - I'll relay that to my good ol' buddy!

 

Hi
Just got my self a ford escort 1600 sport. Its got a 2.0l sohc pinto engine from the sapphire and sierras and so on and i was wondering if the 16v zetec head would fit on the pinto engine block.

 

No.....

 

No they are totally different engines, Pinto is a engine from the 70's where as Zetec is an engine from the 90's.

It's quite interesting that choice of engine being that the Escort is F/F where as the Pinto is a RWD engine, a complete Zetec engine would have been a better choice imo.

This is assuming you don't have a MK1/2 Escort?
