Good morning Chaps.
Wonder if you can help me with this one. The 2.8 Capri has been out of storage for a few weeks now and is getting used a bit, however since being put back on the road Ive noticed its starting to Miss when the car is warm.
Basically its fine warming up, but as soon as she's up to temperature she wont rev past 4k. Its drivable below this amount, but some get worse as the cars heating up.
Ive changed the Coil, Leads, Plugs, Dizzy Cap and cleaned the rotor arm etc. My other thought is Valve seats being shot, so before I go and purchase a set of recon heads is there anything else Ive missed that it could be?
Cheers Nathan

vacuum advance on the dizzy working okay?
valve seat / stem seal damage would give you back pressure (in my experience) and should be easy to spot venting from rocker cover/s
have you compression tested the block?

Ill check any leakage around the covers now. I did one a while ago but for the sake of 20 mins Ill do one now. Vacuum on the Dizzy I havent checked actually so Ill do that also.

OK Update
Compression test shows 150psi across the board, so that seems fine, but I'm thinking this may not show up the recession.
I have noticed arount the left head at the front near the alternator its very oily so this could be the blow off you mentioned. So before I whip the rocker covers off, can adjusting the valves take up some of the recession etc, giving me an extra few months of usage?

When I had this issue on the Stag (it would rev to 4,000rpm when warm and then spit/miss from the exhausts). From changing the coil, leads plugs etc. it turned out to be the new coil I bought (I had another consistent misfire all the way through when I bought the car (that was down to a vacuum leak).
Going from the new County branded coil to the old Bosch Super Red Coil cured it. Just as well as new th Bosch coil is £40! Even on new cars non OE coil packs give me a little grief.
As an aside how clean and free in movement is your metering plate? On some K-jet cars I have had to give them quite a clean to give the car back some grunt.
