SS1 1800 CVH Project now the alarm system

Post by Peter S » Wed Nov 20, 2019 7:17 pm

Hi I'm back :!:
With an empty garage having sold the GTC getting board and not wanting to work on the house I bought a twice stalled project
It was sold as a just needs putting back together but I don't think so. Its got unused tyres still got the moulding bits on the tread but and invoice dated 2006.

It's believed to have a reconditioned 1800 cvh engine but no receipt unable to find engine number any ideas where it is?
Also have 1&1/2 carbs not sure which they are.
The initial restoration looks reasonable new carpets seats recovered but some bits missed.
More later

Do I need a fuel return pipe :?: :?:
Hi removed the new :?: Boot box to discover this

But the NOS fuel pump has no return and although the carb has, surely the float needle valve stops the flow when closed hence my question.
Also are the pipes going into the sender correct :w the ones on my Sabre were different.
I need to replace the main supply line it does not exist in the engine bay :evil: . I understand the middle section is nylon so OK but the joint at the front is very difficult to get so. Could you move the nylon lines forward as the rear is also shot but looks like could lengthen the rubber section?

In other news the engine has never run :!: It's got absolutely no oil in it, but new gaskets and found receipt for CSK 2185 cam, new bearings shells. It's got a head stamped 1.6 and standard CVH rockers can't find anything on the block though so still no sure it's got the longer 1.8 stroke.

Only think that looks different is your longer dipstick so far. I tried a quick search on that camshaft number and drew a blank.

The 1.8 uses an oddball set of crank bearings - is there a number listed for those? Alternatively can you get a picture of the side of the cylinder block?

As to the return pipe; there are a few versions of the tank, and hence where the return hose goes but not so many variants a of the sender available so it might be blocked for that reason but no, it’s not “essential” as long as the fuel pressure doesn’t get too high.

When I googled the cam kit it came up with Scimweb! In 2014 which included your comments :!:
I've a receipt with AEB744U STD BIG END BEARING SET & AEM5540U STD MAIN BEARING SET
I've also got receipts for Z121 ford filter but looks like not fitted and QTB373 Timing belt fitted ( I think)

The 1.8 also has roller bearings in the rockers - that’s a 1.6 IMHO.

The crank bearings are 1.8 although the cam belt is 1.4/1.6 but the bottom sprocket must therefore have been changed as the tooth profile is different between the 1.6 and 1.8. I have it in the back of my mind the 1.6 belt will fit the 1.8 “tall block” if a 1.3 tensioner is used, based on info from a ZVH build.

Peter already stated the head is stamped 1.6

1.6 head on a 1.8 bottom end has been done plenty of times before. With the 1.6 head being considered the better item for performance.

No expereince of European 1.8 CVHs so can't be of further help!

Thanks Phil
Interesting another cam tensioner was in one of the boxes of bits. The cam belt is definitely QTB373.
The cam seems to be a standard one for a 1.1 :!: from the info I found (on the web :w )

The R2A Sierra 1.8 uses flat top pistons I think so with a hemi head that could lead to a lower compression ratio unless they were also changed?

Hi chaps.

As it happens I have a fair amount of knowledge on the 1.8 cvh and a fair amount of pictures too.

This is a European 1.8 block with a 1.6 lean burn head.

The adjustable cam pulley is needed to dial the cam in as the block is 10mm taller than the 1.6 block and the head needs to have ~1mm of material removed to get an acceptable compression ratio. In addition the 1.8 pistons need bigger cutouts for the 1.6 valves.

As a side note..... the rotational assembly is a fair bit lighter in the 1.8 cvh bottom end.

With the position on the dipstick I suspect your engine is a 1.6.

The standard 1.8 sump is rear bowl and your dipstick seems to come from the front. The European block has the dipstick coming out at the rear of the block.

After studying some older photos I've come to the conclusion it is still possible for this to be a 1.8 block. Need more pictures to confirm.

That's a fair old skim needed then, Chris! :shock: Are the cutouts needed because of the skim itself, or simply because they were intended to clear 1.8 valves?

I'm glad you mentioned the dipstick it looks very iffy, looks like it's been bent to go to the front.
