shouldnt be possible since, like i mentioned, its the leading edge of the counterweight that rests against the pin. that said, I have always gotten it close to TDC and then installed the pin, as you suggest.

I'm sure I have not done as many zetecs as others, but I haven't had 20% error with timings and resultant engine performance issues either as someone else has admitted. That's not something to brag about, the screwdriver method is the reason for that error.
What are you even talking about? I've done enough to see these errors first hand. I've seen people post on Team ZX2 about the issue. At first we thought it as the two-piece crank gear design, so did Ford, because they updated the crank gear. After that didn't fix the issue we were still left scratching our heads. My car needed it's second timing belt (180,000 miles) so I replaced it with OEM parts. Notice I didn't have the problem with the first belt? After the new belt lasted less than 100 miles I went back to Ford to talk to the techs. They went through the computer and found the TSB for the belt. It explained how to neutral the gears because of variations of belt design and tolerance, also wear on the gears. After installing the new parts and following the TSB I have not had the issue again. I shared this info with Team ZX2 and this fixed their walking issues as well. So, quit talking like you are some master mechanic and I'm some dumb kid.
I'm not surprised, same person has some arcane theory about 'neutralling sprockets' to prevent belt troubles. Some black magic there if you ask me...............
Well, I am quite good at voodoo. I have to be since people bring me cars other mechaincs have given up on.
I have had no trouble at all with belt walking or engine performance issues and I never loosen sprockets on either VCT or nonVCT zetecs. Simply no need.
You 'simply' have gotten lucky. Stop telling people this because you are going to keep someone from fixing their car. This is yet another procedure put out by Ford. For proper VCT operation the lug has to be at 12 o'clock. If the belt jumps or breaks during operation, it is anyone's guess as to where the lug will end up. Again, I just fixed a ZX2 about three weeks ago by resetting the VCT. That was the only thing I did besides neutral the gears. The shop that did it didn't set the VCT. The belt broke while the engine was running. The belt on my wife's ZX2 broke while the engine was running. This was long before I knew what I know now about timing Zetecs. It was in fact my first timing job on the Zetec. I just replaced it the way the Haynes manual said and the car ran fine. I got lucky. Sometimes you get lucky but it is always best to do it right.
he is not saying to use a degree wheel on the Zetec. he is using degreeing cams as an example of why you should positively make sure the crank is at exactly TDC before doing anything with the cams. especially since you have used the cam bar to positively lock the cams at TDC.
i still dont see how you could use the pin and not get it set to TDC. if it goes into the 1 weighting hole (which likely isnt even there on all cranks), then the crank wont turn in either direction. in which case you remove the pin enough to turn the crank, rotate the crank about 180* and reinstall the pin. then rotate the crank until it rests on the pin. there is no way to use the pin that will set it to BTDC, its just not possible since the leading edge of the counter weight rests against the pin.
Just because you can't figure it out or over think it, doesn't mean it won't work.
and just because there are other ways to do it doesn't make them the correct and proper way to get the job done .... its a two way street here ....
don't get me wrong, I have used a screw drive down the spark plug hole to help confirm TDC. used the timing marks to get it set otherwise. that was the first time, the second time I had the Ford tools and used those. its so simple I don't see any reason to bother with going about it any other way.
There is nothing wrong with using the TDC peg you bought from Ford, but Ford isn't the only one that sells them now are they? You can't trust aftermarket manufactures to make things to the same exacting standards. That would be like saying a stage 2 clutch from Exedy is just as good as one from ACT.
When looking for the damper mark, look close for TWO possibly, the second one is the one to use. Was looking at mine today, it's got 2 on it. I believe the first one past the oil pan bump is an advance timing mark, the second one is for TDC. Put both marks at top of damper, the one on left is the one to use. Line it up with the oil pan bump line.
see that's funny, mine has two and i'm pretty positive that my first mark is what marks TDC. with all of the differences in the marks on these cars i'm starting to think that they might not serve any purpose at all. IMO i think what a person really needs to do, if they are really concerned about the timing mark is locate TDC and the clean that crap out of the crank pulley and mark it on their own with a paint marker. or i suppose you could use a file to make a notch or something like that.
That only works on 95-98. After that it's an upper and lower oil pan, totally different with no notch.
I've already sold one as result of this thread. You can say what you want but when you say something that can cause someone to do the job wrong or have to take it in because you told them resetting the VCT isn't needed, that is when I have an issue.Well, well.
'When did I say that using the screwdriver was only 80% successful?'
You didn't say that, you said you had VCT error problems with about 20% of the ones you did a while back. I locked onto that statement and stashed it mentally. In zetec performance section here I believe, I could not get into archive to retrieve it. Look hard enough and you will find it. Or maybe not, huh. I figured we were past it enough so that you'd be denying it.........
]What have I denied? The error came from replacing broken or skipped belts without resetting the VCT.
'If you install a belt and the teeth don't mesh exactly to the gears they cannot neutral themselves out.'
??? That sentence is engineer doubletalk meaning absolutely nothing. NO belt (or chain) meshes exactly until you line up the parts. Please point out to me how any other engine on the planet does it without all the mumbo-jumbo. EVERY engine either belt or chain driven has to have cam so-called 'neutral' out to the crank or distributor gear or whatever other part is in the train. If you are referring to cam to sprocket itself, the cam can be bolted up tight without being in any exact location except the one you desire to put it in, i.e., it can be retarded or advanced as desired up to enough timing to create troubles either way. Only exception here is VCT since the sprocket must be bolted on in such a way as to maintain cam phasing since cam is read on other end for positioning. Again, another major reason NOT to loosen exhaust cam, you risk not getting it back in proper place. It makes no difference whatever as to the 2 cam gears being slightly off from each other, they CANNOT STAY THAT WAY since engine rotation will allow them to, oh my goodness, neutral themselves to each other as they settle in to the belt teeth. You seem to think there is some sort of locked in distance between sprockets that cannot change during running, that's just plain goofy. The only locked in distance is tooth spacing and the only error that can be there is an entire tooth off if parts not loosened and tension set right.
The distance is locked unless your bolt comes loose. I still don't understand how you think the teeth can mesh or neutral themselves out unless something gives. If they do 'settle' in, that means the belt is wearing. That is not a good thing. The tensioner can only correct so much slack and can't take care of it if the teeth aren't riding in the grooves perfectly.
'the tension between the gears won't be correct'
If you roll engine around and tensioner in range, no problem. What do you think the engine will do? It pulls from one direction ONLY. The applied tension will absolutely be much higher than just allowing all sprockets to 'neutral' to each other at engine rest via loosening of sprockets. Making that highly touted point useless and my sides hurt.
See above explanation.
'Again, it is obvious you don't really understand why the VCT has to be reset and why the teeth on new components won't always mesh properly with the cam gears. The VCT lug (hole in the front of the cam) is infinitely adjustable. If you remove the VCT hub you can put that lug anywhere you want. If you remove the belt and then move the exhaust cam, you might notice the VCT will wind up and spring forward independent of the cam. If the belt jumps or breaks during operation, that lug can stop anywhere. You'll still be able to get the cam lock tool in but you might notice the cam won't stop at TDC. If this is the case, the VCT gear has to be removed and reset.'
No kidding. Do you reckon that if you did not loosen the exhaust cam none of that would or even COULD happen????? Tell me of more Ford brilliance, I'm swooning. As for the lug stopping anywhere, not true, it fits into the oil feed ring exactly halfway between the triple hole set and mark hole. There is a hole to put lug in. If not halfway between the hole patterns as mentioned, damaged and both pulley and VCT cylinder need replacing per Ford instructs. Between VCT cylinder and the feed ring, oil supply is staggered at three 120 degree angles to prevent backdrain out of the cylinder when engine shuts down. If the lug goes anywhere as you say, then you risk startup exhaust cam snapping from VCT cylinder oil draining out at hot shutdown. That feed ring is timed to the VCT cylinder by the lug. It is the CAM itself that can go in anywhere radially inside the ring and VCT assembly. Look at the parts. There is an internal stop that positively limits radial travel, if you'd use that cam casted hex, you'd know that. VCT cannot just spring anywhere radially as the spring must have a certain amount of push back to bring the cam back advanced against the direction of normal rotation. Any less assist would result in codes. If the cam does not stop at TDC then it has not been brought against the stop internally before timing. Again, if parts not loosened that CANNOT happen. You are way unnecessarily complicating matters, the only thing that matters is that VCT cylinder must be against internal stop at the time camtool goes in to prevent overadvance.
Strange, it happens even if you don't loosen the gears, e.g. the belt breaks. I've seen this first hand, so has Ford, or they wouldn't have put out the TSB. I know there is a positive stop in the hub. Guess what, it relies on the VCT gear to be in a certain position. If the hub is not stationary (the belt holding it) it can stop anywhere. When the belt breaks the hub cannot be a positive stop because it is not being held in place by the belt.
I've had the cylinder off, took maybe 15 seconds to figure out how it works. The stuff I got is from Ford 1999 Contour/Mystique service manual dated 12-98, basic engine-2.0L, section 303-01A-11, "working on the VCT unit". Maybe YOU should go back and study it, that's where I got my info.
Use the book when it suits you? That sounds like many major religions I can think of. Ford doesn't put out books and then just forget about them. The books do get revised and updated. The procedures I use are as recent as 2008 when I got the TSB printed at the dealership. I've got the factory service manuals as well, maybe you should go to Ford and have the TSB's printed out for you.
Gotten lucky so far with his timing? That's rich. I was timing chain driven twin cam engines similar to this back in early eighties on motorcycles, including custom timings with tight fit interference motors (79-83 Honda DOHC). I have degreed in so many automotive engines of various types it's not funny, but that has no worth apparently to you of the screwdriver clan. I have built myriad small and big block engines Chev, Ford and Mopar, lots of AMC up to prostock motors. While I respect engineers I also take them with a grain of salt, they flub up just like everyone else. By the way, there was NEVER a need to 'neutral' twin cam drives. Arcane BS like I said.
Were any of those engines equipped with a varible cam system?
The information I give out will work on any VCT zetec, sorry if it seems I'm pouring water on your dvd sales. There are many ways to do many things, please don't run me down just because you don't like what I say.
I can't find the other pages but you get the idea from the first page.
