The engine capacity is normally where you say the 20 is on the front of
the block, certainly on later CVH's and Zetec's
The Sierra block i had said 1.8 there.
The early FWD CVH heads also had the cross hatch marks.
The easy way to tell if it's really a CVH rather than a ZVH (Zetc block,
CVH head), where is the oil filter.
If it's on the back of the block under then inlet manifold then it's a
CVH, if it's hung off the oil pump at the bottom corner of the engine
then it's a ZVH.

Hi All,
General Knowledge, Starter for 10:
I've just bought a red Coupe, no Q-061, nominally for spares, but it
may get fixed up some day. Anyway, the seller thought it had a 2.0 CVH
engine in it, but I'm not sure. The question is how can I tell easily?
I know that Quantum did have access to US-spec 2.0 engines, as they
were mentioned in some brochures, and in the Top Gear article on the
2+2. But do I have one?
The seller based his assumption on the fact that the 1600 sump gasket
didn't fit, only the one from the 1.8 Sierra, and that the block has
"20" cast into the front face, just below the middle two exhaust
ports. For what it's worth, it has a BP285 cam fitted and a
rectangular-top Weber, like the one on the early XR2s. The head has
the cross-hatch marks cast into it, like the Sierra head. The
distributor and thermostat housing are as per Fiesta, and there is no
Timing Belt Cover.
Now, I have a couple of Sierra 1.8 engines in the shed, and one of
them has "27" cast into the block, in the same place as the "20" on
this one. So I suspect that is just a batch mark. Personally, I
suspect it's a Sierra unit that someone has converted to FWD and,
maybe done some tuning on. I've heard it running, but never driven it,
so it's hard to say what sort of power it has.
So, is there any easy way that I can tell what it is? I know the 1.8
is taller than the 1.6, but what about the 2.0? Are there any
distinctive differences between the US and UK engines? Do the casting
marks mean anything? Will the Engine No. tell me anything?
I know I can take the head off and know for sure, but it's cold and I
have a lot of other things to do. Any ideas, anyone, please?
Thanks,
Dave.
