cvh dry sump system
good evening guys and girls
i have joined your site to hopefully gain some help and assistance with a cvh dry sump system, i appear to be drawing a blank on finding a cvh dry
system. Pace used to make them but are disinterested and i am finding it increasingly difficult to find a system.
therefore i hope you guys dont mind in helping out with some info on your systems for the cvh and any pics if at all possible.
i own a 1985 escort rs turbo series one that is a pure track car, wet sump and baffled/gated sumps are an option but the cvh oil pumps are known for
being unreliable, its been 12 years in ownership and development and its now fully track day orientated. accusump is an idea i am talking with a
contact that owns an ex race car and wonderd if you may have experienced this
but i would ask you guys your opinions also
i hope you dont mind me joining your site to ask such questions but i thought where better to ask than here, like minded people with a common
interest
many thanks for your help and taking to time to read my enquiry
Steve

I run an accusump and very good it is.
Accusump
Low cost
Simplicity
Ease of install
Dry sump
Expensive
Complex
Complicated to install
Dry sumps really come into their own when you are dropping the engine as low as possible in the chassis and trying to gain every last a few BHP with
negative pressure under the pistons, for just buzzing around a track an accusump has to be the way to go IMHO.

Hi Mark
thats good feedback, so thank you
the wet sump as you say is very expensive and a few zetec owners are telling me its over kill but i have concerns over the cvh oil pumps and their
inherent gears being a weak point, billet gears are also an option but difficult to get made
onwards and upwards

Isnt the CVH sum largely the same as a Zetec one (or is that just the 1.8 RWD CVH?)

I'd agree with this. Plenty of room under the bonnet in an RS turbo for an accusump, and the non electronic version is pretty straight
forward.
Pics as well please! a good friend has an immaculate RS under blankets in his garage, and would like to see it

accusump and alike will not replace the oil pump. Its really just an oil accumulator...

Although accusumps can be ok, (i run one), the problem with them is it doesnt stop oil starvation, It kicks in once the oil pressure is low. So it
just helps the situation, doesnt cure it....
However from your posts, doesnt look like your having oil problems, Dry sump pumps are just as likely to fail to be honest.

I ran a high powerd accusumped cvh in my track orientated Westfield that I recently sold, so hopefully I'm in a good position to advise...
First off, the cvh oil pump....I would question those who said it's un reliable...It isn't and it's not a known weekspot unless
installed incorrectly. By this, you must be careful when installing the pump not to force align it with the engine block, it should have a natural
seating position, and there is play in the oil pump around the securing screws (i.e. it can be moved slightly to align it correctly)...if this is
done, then there are no issues...Again, being a CVH, ensure oil changed regulary.
Accusump.....tons of drivel on the internet about them blowing up engines...again probably bollox and down to incorrect instalation. I agree with
Eddie99, and ultimately a dry sump is better at stopping extreme surge, but fo 99% of the time, the accusump is ok......they have been around for many
years, and there is good reason for that.
My story goes like this...I fitted R888's to my westfield and all of a sudden braking and cornering speeds increased, and I was getting signs of
oil surge...I fitted an accusump and it went away. engine remained 100% reliable, and I regulary checked the cam lift as I was running solid lifters.
Think auto did a clever one way valve that was built into the oil filter take off plate, this made the install very easy, and cheap.
As for the dry sump thing....forget it...I spent 4 years trying to track one down and failed :-(

RWD cvh originated from the states and begat the zetec, the euro/fwd cvh has very little in the way of interchangable parts with the rwd/zetec.
The sump part isn't really the problem with dry sump its the pumps/ mounting them and the belt drive that cost money/cause headaches
Never under estimate the ingenuity of an idiot!

The block of a zetec is VERY similar (i.e. cylinder spacing, most of the water and oil ways and head bolts) to the 1.6 cvh...Hence why bolting a cvh
head onto a zetec block is now quite common place.
The sumps will not transfer as the bolts on a zetec sump are a). less of them, and b). in a different place...Possible to conver if you are happe to
drill out the engine block. That said, the cvh sump (even though it's a bit f pressed tin), is quite good in a RWD, it has a baffle plate over
the oil pick up which helps.

Begging the question....why dry sump a cvh in the first place?
