Can you get core plug sets new?

I bought this set on e-bay: http://www.ebay.co.uk/itm/Core-Plugs-Beagle-Cavalier-Chevanne-Viva-Chevette-Firenza-RWD-OHV-1-1-1-2-1-3-/150314232815?pt=LH_DefaultDomain_3&fits=Car+Make%3AVauxhall|Model%3AViva&hash=item22ff6d2bef
Not installed it yet, but I think should be fine.

Hello everybody! Unbelievably six years have passed since i've posted something about my Viva. :oops: Good news is that i still own my Viva, bad news - it still sits in garage with empty engine bay. To my excuse, i can say, that lot of time was spent on other projects: i repaired and got back on the road my 1977 Opel Commodore Coupe and, celebrating it's 40th birthday, in 2017 a 4500 km roadtrip was made to Opel's Russelsheim factory, where this Commodore was born forty years ago.

That's me with Commodore

At the historic gate of Opel factory with Adam Opel himself. :)

Then, in 2018, i finally fulfilled my dream of owning a classic american car - i bought a 1974 Lincoln Continental Mark IV.
Image
The day i bought it

Image
The car was in fairly good shape, but still some bodywork was needed.

Image
Finished product. :)

But, luckily, not all these years were dedicated just to non-Vauxhall cars. :) Mostly i've tried to find and buy all the parts needed for engine repairs. When the valve guides were repaired, at first it was decided to keep original valves, but, after inspecting them more closely, it was decided to replace valves.
Image

Image

Image

There was a problem with valve springs: one of the springs at some point was replaced with wrong, cut to "fit" spring:
Image

Luckily i was able to find a set of new valve springs:
Image

One thing, that i've searched for, for quite some time, was the oil pump. Finally i've bought a genuine GM oil pump. It was sold as oil pump for 1256cc Vauxhall Chevette, but i did not saw any significant difference with original pump:

Also i bought engine gasket kits and brand new water pump.
Image

Image

Image

Brand new engine and gearbox mounts:
Image

Clutch was badly worn and needed to be replaced. Original clutch on my car was Borg&Beck, so i wanted to find clutch parts from exactly this manufacturer.
Image

Bought new clutch cable for LHD car, at least, judging by information available in this forum, it should fit LHD Viva.

Have you checked your oil pump for the correct position of the slot on the end of the shaft that interfaces with the distributor? The later 1256 engine oil pumps have a centre slot drive to mate with a centre drive dizzy - usually Bosch but you can get centre drive Delco - the original dizzy is probably offset slot drive.

Thanks for Your advice! Yes, I've checked it - NOS oil pump has correct slot for my distributor-slot is offset just as my old pump. As i wrote, it was advertised as oil pump from 1256 Chevette, but i don't know if it's indeed for Chevette.

So, slowly i keep moving forward. Crankshaft has been cleaned and reground to fit undersize bearings.

Image

I've noticed interesting issue with connecting rod orientation.
Image

Image

Image
In these pictures piston/rod assemblies are placed on table with notches on pistons indicating FRONT facing up. You can see in one of the photos, that one connecting rod is positioned other way around. I am pretty sure, that this is from factory as it is very unlikely, that this engine has ever been overhauled. Factory shop manual does not say anything about correct connecting rod orientation. The only thing to look for is notches on pistons. When i will replace pistons, should or can i place all connecting rods on pistons same way or is it not that important?

A little, but very important update. Ring gear on my flywheel was badly damaged, worn out.
Image
That was a problem, because I could not find a replacement ring gear anywhere. In the end Adrian Miller saved me (us?) by offering new ring gears for sale. Thank You very much! I already installed the new ring gear and it looks and fits nicely.
Image

Image

Image
Not directly related to ongoing engine repairs, but still interesting finding: i bought genuine Vauxhall Viva factory shop manuals and also a Vauxhall Viva parts catalogue

Hi, everybody! Fulfilling this topic's title, restoration is truly slow, but there is some progress. :D
Before assembling connecting rods with new pistons, I'd decided to check the weight of the pistons, rods and pins. Pistons and pins were OK, but I was surprised, that there was a 10 gram difference between lightest and heaviest rod. So I'd made DIY tool for weighing connecting rods.
Image

Weight almost exactly same on all rods.
Image

Something's cooking in owen. :angrywife:
Image

Piston and rod assemblies with rings installed
Image

I'd replaced all the core plugs and camshaft bearings
Image

Image

I wanted to sandblast the engine prior to painting it, so I'd temporarily assembled the engine block with head, oil pan, valve cover and plugged all threads and holes.
Image

After sandblasting.
Image
Image

I'd took the engine apart and thoroughly washed out all the sand from head and block. Almost looks like freshly cast. :)
Image
Image

You can have it in any color you like as long as it's black.
Image
Image

Also I'd cleaned and sent to recoat with zinc all the bolts, nuts and washers.
Image

Installing crankshaft and camshaft.
Image
Image

Pistons and connecting rods installed.

Someone decided, that everything is going too well, so at one point I discovered, that in all these years I've lost somewhere valve spring caps and retaining collars for all eight valves. :new2_shrug: I would love to buy eight valve caps and sixteen collars if anyone has them.
Image
Parts number 16 and 17.

Also I'm searching for decent starter rubber boot. Part number 23.
Image

Maybe someone has a spare bonnet lock? Part number 1.
Image

I would appreciate if anyone has something from this list of parts, that I need.
