Morning All, Just taken the head off the CVH from my latest acquisition and the mystery deepens. As you will recall, the previous owner thought it was a 2.0 and knew it had some fancy bits fitted, but wasn't sure of the details. Well, I had to have a look didn't I...?
Bore is 83mm, Stroke is 88mm, which, I believe, is the same as the 1905cc American engine. However, it has the 81SM6090 Head (with the Cross-Hatching that is supposedly so desirable), and the block seems to be the 1.6 height, not the 1.8, as the 1.6 cam belt cover fits, which it doesn't on the Sierra block. "E8EE", "AA" and "9E25" are cast into the block. Pistons are 'Hemi' type, with large cutouts cast in them for valves "3019P", "9-6" and "0.75mm" marked in the crowns. The head appears to have 43mm inlet valves fitted. Haven't taken the valves out, so can't accurately measure them, but they aren't 42 (standard) or 45mm. Might be 42.6 or might be 43.5. Ports look to have been modified, and the cam is a Piper BP285. Was running a Weber DFT carb and a 4-2-1 manifold into a standard exhaust. Unfortunately, I never actually drove the thing as it was out of MoT. Was misfiring badly, but turned out to have a u/s plug lead and a cracked coil terminal, so that should be easy to fix. Anyway, I'm interested to hear any ideas as to the origin of the engine, as I'm going to need some spares for it. At a minimum, I need a head gasket set and stretch bolts. Plan at the moment is a de-coke and re-assembly, ready to go into the 2+2, either using the Weber, or a set of R6 bike carbs that came with it. So, if any of you can provide any information, based on the above, I'll be very grateful.
