Can't help you with a stock one. 

 

I only have a modified one with ITBs that makes 130whp :classic_biggrin:

 

I finally ordered the proper venturies. Maybe I'll get a few more hp after them

I am months behind but I sell a Complete built Zetec for 3500.00 + a rebuildable exchange

@1turbofocus I was wondering if you were still in business.  This Duratec complete long block in 12:1 compression ratio seems like a great choice for a Birkin 7!

The 2.3 would be a good option , a great Option would be the 2.5 Duratec 4 Cyl from the Fusion if its TQ and HP your looking for

Jeff is a great guy and about as straight as they come.  One problem an independent machine shop will have with your Zetec is getting the valve lash correct.  This is normally done with different thickness cam followers, although the valve stems can be cut. Its pretty tedious to get it just right.   I have a pretty good selection of followers.  Older engines use shims that sit on top of a follower, but if your engine came that way it was probably converted...the shims add about 3 grams to the weight of the valvetrain.

 

I will be glad to help with followers.  I have at least 50 .

 

Otherwise you could do worse than sending the head to Eric at Quicksilver.  They can cut all three valve angles at the same time. Anything to do with the dry sump setup they are experts on also.  They have  built hundreds of these with dry sump for FF2000.

 

Question as somebody for whom valve train optimization is a big black box. My Zetec was modified to have lash caps during the original build. At some point in time one of the lash caps was seized on and I replaced it (after a VERY long search to find a match). Machine shop did some valve magic they said they needed to do to make things work again properly. 

 

Does any of this sound normal? Any issues that can be caused by using lash caps? Stock motors don't use them.

The Mystique/Contour Zetecs have a lash cap that fits on a cam follower, much like a Duratec, but I suspect you are talking about a shim on top of the valve stem.  You usually use than when you have camshafts that have been ground to a smaller than standard base circle.  The little cap makes up the difference.  These are fairly standard, (6mm in this case) the last time I got some was from Supertech.    Not sure how these could seize, but they can crack.

Oh, I didn't know that Mystique and Contours had them. Maybe I do have a stock motor after all with internals. Who the hell knows but this supports my theory that Contour or Mistique was the donor car for the VCT stamped valve cover engine. 

 

This is what the troubled lash cap looked like. Shop said they had to use vice grips to get it off the stem

Lash caps work fine. All those Jaguar twin cam engines from the 1950s to the 1990s used them. Would it be better to just use the original stuff? maybe a little, but very little. You need to verify the caps you use fit properly and do not interfere with the valve retainer and the valve keepers. As mentioned above you probably have reground cams. To get more cam lift they grind material off the base circle (bottom of the lobe). There would not be any original parts to compensate. To determine what the cams are is a real time-consuming task. It can be done but it requires some measurement tools and a procedure that isn't strait forward. Was the bad lash cap from the cylinder that has been misfiring? One easier cam test would be to use a caliper and measure from the base circle to the top of the cam. This would give you an idea if a cam lobe were worn.  I suspect the lash caps in your engine are correct for the application. You haven't had any other problems. Perhaps the cam was worn down and the lash cap got beat up from the cam after it was worn down.
