CVH engine - Tell me more.
Sorry to be all questions again, it wont be long now till i actually buy something i promise!
Fairly at home with a pinto/crossflow/zetec. Or atleast, i know enough to be happy to buy one and that.
However this afternoon i looked at a Se westy with a CVH in it.
- Apparently its a 1.9 and was previously on (expensive) throttlebodies, which the previous removed at sale for another project. Now on twin
carbs.
I believe the 1.9l is rare, in the uk certainly, but reading up also saw :- "A popular conversion for the 1600 is to take it to 1905cc with
cranks and rods from the 1800 CVH engine and special pistons."
- So maybe its a one of them?
Anyway, seams to go well enough, apparently the previous owner was also a demon for changing the oil, which reading about cvh cams wearing maybe isnt
a bad thing.
But yeah, any thoughts? Seams to go all right, just unsure of the unfamiliar.
- Bit rough, well throaty, at tick over.
Its also a live rear car, first one ive been in.
- Seamed ok, just a bit less soft, clunker over bumps?
I think it was first registered 1995. Otherwise fairly nice, minor surface rust on chassis, few chips in bonnet, flat board seats, plan hoop (not rac
style), Asking £4k (going to stick on PH for £4.2 at the end of the week)

You can have a whole book about CVHs if you like!
http://www.locostbuilders.co.uk/viewthread.php?tid=95669
Is that a shameless plug? I guess it probably is!
For what its worth, I liked the CVH I had in my fiesta 1.4 ghia back in the day...

what are you actually asking ?? the 1.9 may be a boredn out 1.8 leaving any further boring out of the question, the zetec is a far easier to find
engine the CVGH had problems with oil consumption as it tended to burn more than Iraq during the conflict are u asking for our thoughts on u
purchasing?? if so what ithe price ? and the full spec. I would rather have a zetec or redtop engined car than a cvh a ZVH conversion offers more
power

wouldnt bother with a cvh they are crap compaired to the zetec only way to make them better is to do a zvh and add a turbo and then you are wasting a
good 16 valve head .
some people dream of sucsess, others just get on and do it !!

Well, just asking how it compairs to crossflow or pinto i guess.
My budget is closer to £4 than anything else, so a zetec is largly out of budget.
Did also look at this on saturday. http://www.pistonheads.com/sales/664863.htm
Although for a 2005 its not very tidy at all. Body work and engine install far neater on the 1995 westy. Nice wheels/tyres/dash etc.
- Im not drunk eather, sleep deprived, yes. Drunk, no.

Perhaps you should also look at these:
Blue 1990 Striker or Green/Yellow 2002
Striker or Yellow 1997 Stylus
I know they are all of a Sylva ilk, but they would Im sure be well worth the money. All absolutely NTDWM, But I do personnaly like them, just a shame
Im down here in Oz

Hi
The CVH was a good solid engine with quite a bit of tuning potential. Also there are many companies doing large bore conversions on the 1600 versions.
But many of them are to be avoided as they use liners in the block and there was just not enough material to support them long term. Not payed any
attention to the 1800 American unit that has been converted to a 1900. But wood suspect it will have no more power than a tuned 1600. And the 1600
that are tuned are a known item that perform great and reliably unlike many of the conversion ones.
But it has to be said though that a well tuned 1600 CVH will only be on a par with a stock silver top 1800 with the 2Ltr cams fitted IE a 130ps spec
unit with 160bhp by the time you have put a decent exhaust manifold and carbs/throttle bodies on. Either way a tuned CVH or a stock zetec will end up
about the same cost by the time they are fully installed.
Cheers Matt

Right ok.
Bit of a mixed welcome, but ive done a bit more reading around and it doesnt seam to a total no-no as such.
- As i say, i dont really want to go over budget becuase i simple done have the money, and i dont really want to spend it if it did, so a newer
engine/car isnt nessarally an option.
I know the xflow is a nice engine, and there are a lot of them about, but i gues there must be a fair few cvh's about its within my life time
that they where supperseded (and im only little).
As for the strikers, certainly nice cars, but imve sort of got my heart set on a westy/indy. Im also 6ft2 which i believe is pushing it for a
striker?
- I have seen that MK to, deffonatly one to have a look at, although i would prefer not to get a pre SVA car is poss.

ive got a tuned 1600cvh in mine and as a engine think its good, i know its not a 16vZetec but you wouldnt get one of those in a Westfield for £4k.
how about this for £4k if looking at engines and potential performance
http://www.pistonheads.com/sales/624546.htm
think its a bit of a question what you want for your money, all out performance or good summer fun, only thing as the 1900cvh is a special i would try
and get as much info on engine spec as possible, a lumpy tickover pay indicate a good level of tune, would be good to find out how you can prove
capacity, may get a indication of performance Cam ect as think Kent cams stamp a ID number on the end of the cam but cant remember which end!

The CVH isn't a great unit but not that bad, the good news is if you want to convert to a Zetec later it is relatively easy to go from CVH to
Silver top Zetec.
For example both the inlet and exhaust manifolds can be converted to Zetec and one of the engine mounts bolts straight on.
Forget Xflo engines they are ancient technology they don't produce a lot of power without spending big bucks and rebuilds can be expensive.

Yeah it would be good to find out what its prevous life as been.
- Certianly the current owner beleves the owner before him (cars second owner) spent a lot on the engine, hence the frequent oil changes etc.
The cam cover is covered in fins (cast) which doesnt seam to be common. Or atlease ive not found another googling around. Should have taken some
pics.
If nothing else its nice to know a Zetec convert wouldnt be out of the question. I cant invisage doing this out of choice, but its always good to have
a follow on plan should it go up in smoke in a big way!
- Did look at that F27, looks a nice car, although its three hours south from here!

ahh does nobody understand the magic of the cvh engine
the 1.9 engien is based on the american cvh long block engine slightly over bored by a mil or so it offers more torque and a shade over 200hp in tuned
na form the magic really happens with the adition of a t3 or hybrid turbo 1.9 cvh s have been known to produce over 400hp you can also use parts of
the cvh to cure the ills of its horrible sucessor the zetech by fitting a 8 valve cvh head to the zetech bottom end you cure the low down torque
problems inherant with tuned zetech engines

The fins are simply an RS1600i (rare mk3 excort model) rocker cover that usually go for £50+ on ebay etc.
Who said the CVH burns oil lol??! I've run numerous 1600 CVH's in various forms (turbo'd + tuned NA) and NON of them burned any oil.
The only mechanical weakness is the cam lobe on no.3 (if I remember rightly) cylinder which has a restricted oil supply.
As Jamie says though, the CVH's true potential is in turbo form, cheap easy power. eg my old set up was a bog standard, rebuilt 1600 lean burn
(XR2 engine so cast pistons), 9.6 compression, coupled with a T25 did 150bhp on a single webber carb at only 10psi boost all day long.
Costs for rebuilds are good too, at least as cheap as a zetec I'd say.

In comparison to the Pinto or X-flow the CVH is vastly better IMHO and not much more difficult to install (only talking about the 1600 here). As
standard it's got wacking great big valves, nice hemi' chambers (on pre-85 engines) and good port shape and valve angles.
With a bump up in the CR, solid tappets, a well chosen cam and a bit of head work they can produce very good power for their class. But it has to be
said, with zetecs so plentiful it's almost silly not to. The bottom ends are very similar so swapping them seems pretty easy. Thats the route
we're about to take from the CVH, so lots of CVH bits available soon if you want them! 
Noticed you're also a loogabruga student, SNAP!

Ah, excellent!
- Yeah, just finishing sandwich year on friday and back for another two years this October.
I bought the car tonight and drove it home in the falling sunny. Magical. We'll have to meet up some time.

that looks very cool, though I dare say better with the wheels black as in the first picture?
Do you know anyone else at Lufbra with a 7? Strange story, but I ran into the back of a seven (had a K series in it I later learned)......only really
really light contact as I swerved and hit the kerb, so only damaging his rear arch (whilst completely ruining the front arm on my car). When speaking
to the lad after it turned out he was a lufbra student just on the way back down after the hols (coincidence, considering I went there).
Anyway, sorry back on topic, car looks spot on! does it go well?

only slight problem with that is the pre 85 engine is actually the worst one to use the bearings were made of poor quality metal leading to crank wear
both on the mains and big ends also the port design was revised on later engines giving better flow which means less metal to remove although if you
remove metal from the ports you also need to remove alot from the back of the port around the valve or the air stalls the combustion volumes did not
change drastically during the run of the cvh but the latter engine has better bearings so even if you plan to rebuild it the crank will be in better
shape the head is more condusive to efi and is fine for unleaded post 86 althought there will be a star stamped above the part no s on the head above
the alternator i have never known cm bearings to wear as sugester or cams infact most just rattle due to worn lifters and low oil pressure bits to
watch out for are friday afternoon engines where bearing sizes can be way in excess of overbore sizes as can tappets and sont mix and match cvh parts
as the oil pumps changed and there were other subtle changes newman do a nice cam and i make solid lifters in two types shimm type or easily
adjustable lockijng bolt type which are aimed at the road / trackday market bolt type are £89 a set inc shimm type are £120 in steel or £220 in
titanium yes we do rev them that hard lol

Wrote a reply but it seams to have got lost.
I agree about the wheels, but the first pic are his second set, which where not for sale with the car.
But yeah, car goes well. Well, it did, more on that later.
Ive not realy got into the carclub/autosoc ring of people at luffy, proberbly will do now, but it wouldnt supprise me if there are a few westys about
what with it being a techincal/engineering uni.
- Certainly from working at the union on of the DJs (ex student) has a SEiW westy in navy.
Thanks for your thoughts Jamie. I cant for the life of me read the engine number by torchlight, but i guess that would tell me more about what i
have?
I have a load of paperwork for the previous/orignal engine, but this one was put into the car by the owner before me, and has ended up coming with
basicaly no paperwork at all. Has the cast/finned rocker cover, and obviously bored to 1.9l from a 1.6 but other than that i know little. Carbs car
dellorto DHLA 40g's

But yeah, moving on from that. After a few smaller runs out i did an hour jaunt own to loughborough and on getting there ran into problems.
It was fine on the way down, dual carriage way, 70mph is all the way. Then started fine once we had got there (needed to move it across town to leave
parked for the day) and after 200yrds it basically sputtered to a stop.
I was warm after the run, and i was with another mate, showing them the car for the first time, and i did boot it a bit. Although as far as i know
kept well within rev limitations.
I will now just about fire, but theres no power at all, and you can only (just) keep it going with a lot of accelerator work.
Ive had the carbs off yesterday and cleaned though, as fuelling was my best first guess after the ignition seamed dry and the spark good.
Only other thing ive noticed is the timing belt seams slacker than i would expect. So instantly im thinking it could have jumped a tooth...?
Only thing is as it has a non-factory cam pulley i dont know where/what the timing arks are for it.
Any thoughts very much welcomed!
Thanks, Daniel.
