Cylinder bores now de-glazed & everything cleaned up with brake cleaner & oiled to avoid rust flashing.
Prior to de-glazing the crank journals were wrapped in plastic & paper towel stuffed down the bottom of the cylinders to catch most of the gritty oily waste.
New piston rings have had their gaps sized for each bore/piston (all gaps within the range of.012-.014") & now fitted to pistons.
Will orientate ring gaps as per the workshop manual, ie:- Oil Ring gap to face away from the camshaft & the two compression rings located so that the three gaps are equally spaced around each piston.
I've cut a couple of pieces of hose to put over the con rod bolts to protect the bores & crank journals while I lower the pistons into the bores.
Now looking for my ring compression tool which has gone walkabout, so maybe a trip to the auto parts store. :huh:

We keep chipping away ;)

cheers

Pierre, if you keep doing the job that professionally you will have a line up of new customers wanting you to do their engines. Fitting rings to pistons can be fun especially if they are small rings like on a mower engine. So I started using my ring compressor back to front by fitting the rings on the outside of the compressor and then sliding the lot over the piston and slipping them off one at a time.
All this hard work will pay you back in the long run with a sweet running engine.

Thats great to make progress like this, even if it doesn't completely fix all your problems it will definitely run a lot better and give a good feeling of satisfaction knowing you've done it

Hi guys, the recon Cylinder Head has been re-fitted to the engine block. (thanks to my two sons - saved me hiring a trailer & hoist)
The head & manifold faces were re-faced & the back of the guides machined to take new style Posi Stem Seals for the valves, replacing the felt valve seals supplied with the first VCR Kit. K-Line Valve Guide-Liners were also installed.

A check on the exhaust manifold highlighted a ~.020" out of flat with a straight edge, so I've had that refaced as well.

New gaskets fitted





I just need to re-set the static timing, flush radiator & fill with coolant, then refit / seal both the engine side plate cover & sump (with its infamous gaskets). Refill with oil.

I noticed the exhaust manifold to front pipe flange gasket had some blow by going on when I removed it, so I'll need to re-visit this & re-align that correctly & add some sealant paste at the join.
Probably need to make the front pipe mounting point rigid to the engine/gearbox & the rest of the exhaust system attached by rubber mounts so any engine movement doesn't try to pull the joint apart .
Anyone used the JB RTV Hi-temp paste?

cheers

Also need to sort out that poor oil return pipe connection from the filter to the block as mentioned in previous post.

Looking like it all has a better chance of sealing up now

I have only ever used Maniseal

I would have thought that the engine pipe usually is fixed to the engine/gearbox then on hangers after that. SOunds like the head is better than new now too. Maniseal is the best sealnat on exhaust systems plus I used it on the joints and it made it easy to break the joint a year later.
