The timing chain assembly looks as beefy as the Dodge's! Smile

Rick,

Now you are talking power chains. This is a Hy-Vo chain. A version of this was used as a transfer chain on the Oldsmobile Toronado between the 7.5 litre V8 engine and the automatic transmission handling up to 510 ft/lbs of torque.

has this turned into a case of you show me your timing chain and I'll show you mine? Laughing

today's progress was getting the cylinder head finished.
I started this morning with these.....

as you can see I managed to bend the old cover when removing it so a new one had to be made.....I think the photos tell the tale...

one new piece of 3mm steel...

you will have to excuse the welding....I had to make it water tight and looks aren't an issue as its the rear of the head anyway.

then I got on with the front end of the cylinder head....

so there we go, one complete rebuilt Alvis TA14 cylinder head.
I just need my piston rings to turn up now, then I can the pistons in and put the rest of it together.

more tomorrow, I'm going to make a new water jacket end plate for the engine block and clean the water pump....

Jason,

This is not meant to be an egg sucking lesson but be sure to check the ring end gap in the bore before installing on the pistons (3.5 thou per inch of bore).

Thanks for that Art, I'm glad you mentioned the end gaps.
I was just going to do the end gaps the same as the old rings....but thinking about it, if the old rings are worn, then the gap would be out.

having said that, the rings I've ordered are correct for the Alvis +030 as the pistons are stamped +030......so the fitting instructions could have the end gap size.....if not I'll have to do some maths Smile

Neat job anyway but what is notable is how simple the casting is and its closure plates that were so handy for heater return & flow to be fitted if extra comfort is required. (our Rover 16 has the same set up) later they made CI castings more elaborate to save weight but which are easily damaged and corrode faster

cheers Phil, compared to a modern engine, its a very simple and rugged engine....its very very solid and weighs...a LOT

today's progress was supposed to be the water jacket end plate....but something happened this morning.....more on the water jacket plate later.

this is what happened this morning.....postman brought these...woohoo Laughing

you may also have noticed the engine is now the right way up, I built a wooden frame to stand it on as a engine stand wouldn't hold the weight.

so new rings fitted....

then the lifters were put back in....

and the cylinder head studs refitted....

then I got a bit carried away......cylinder head fitted with new copper gasket...

tappets / rockers set

distributor and oil pump drive...

distributor refitted...

then there was the original plan for today.......
one water jacket on the block requiring a cover.....

one new piece of 3mm steel....

and fitted....

then I got carried away and started re-fitting loads of stuff.........
as it looks tonight......

so its been a very busy day and I'm now relaxing with a beer Wink

more tomorrow.........

Fascinating read. Excellent to see so many pictures.
Any reason why the copper pipe has such a long length?

Seems it could be much shorter, almost touching the exhaust now?

hi mate, the copper pipe is a bit longer than the original one, its because I don't have a pipe bender and I was struggling to make the tight bends without kinking the pipe.

it won't touch the exhaust pipe, it just looks like it will with the angle that photo was taken at. The exhaust down pipe (still on the truck) is angled away from the engine block, so no issues there.

Kev Very Happy

steady Kev....I've still quite a bit to do,

jobs to do list...

water pump to clean up
engine mounts to clean up and paint
crankshaft pulley to clean up and paint
clutch to get re-lined (3 day turn around)
engine bay to clean out and a few scratches to sort out

having said all that.....in the next few days I may run the engine out of the car to check everything is ok.

I'll video it and post it up, when its running again. Wink

so today's progress......

the water pump......

cleaned up and new gaskets.....

then moved on to the clutch housing which is/was very rough.....

both parts washed thoroughly with plenty of soap and water to remove any traces of asbestos !!!!

then wire wheeled......

and painted satin black....

that's as far as I've got with the clutch cover but there's no rush as the clutch relining takes 3 days.

more tomorrow....

sorry for the lack of updates.....I'm a self employed mechanical engineer and I'm on contract to a large chemical factory and to cut a long story short.....I've had a very very busy week since Tuesday.

I'm working tomorrow and I'm at a car show at Ripon, north yorkshire on sunday so I'll get on with updating the thread next week.
