Hello!
I am in the final stages og assembling the engine.
The heads are back from machining, and I am anxious to get it all back together :D

But, as always, I have a few questions.

1. On which side should the brass vacuum outlet be? picture #1.
My car is a 4th series.

2.Is it possible to fit the heads before you fit the inlet manifolds?

3. picture #3 And what are these things, on the inlet manifolds? are they the petrol drain mentioned in the workshop manual?  Are they needed, and won't they introduce air leaks?

1. The brass vacuum outlet connects via black rubber pipe to the Trico windscreen washer pump which sits on top of the aluminium tank mounted just ahead of the voltage regulator on the LHS of the engine bay to the side of the radiator.
2. It may be possible but not advised due to access to the nuts in the V.
3. The drains should have a unions with  narrow copper pipes which themselves pass to the rear of the engine by the rear engine mounts. Any fuel then drains behind the engine by the flywheel cover.
Hope this helps.
Chris

This is very helpful Chris, thank you !

I have fitted one of the heads, so I’ll proceed to fit the intake onto this now.
Then I’ll fit the intake to the second head before fitting the second head to the block.

I think I will plug the fuel drain holes, as one of them has been badly damaged.

Thank you Chris!

Check the condition of the 2 inlet manifolds carefully before fitting Torstein - quite often these days there is corrosion and sometimes frost damage resulting in fine cracks.
Chris

Thank you for the heads up!
I will check carefully

In the 2 liter motors, you can fit the inlet manifolds after the heads are mounted - they are smaller, and there is room. In the 2.5 liter engines, the manifolds grew in size, and can't be fitted later. So your current process is correct.

Thank you Geoff!

You probably know this... check that the upper faces of the inlet manifolds are level with each other. A small discrepancy can be adjusted by different thicknesses of gasket between them and the carb's lower manifold.

Good advice William, thank you!

really looking forward to starting it up.

I'm going to make a frame for the engine and radiator and start it up on the bench, as per advice given in the "50 years of dirty hands" by Clive Beattie

Good idea. Check for problems, easy to fix minor leaks.

Further progress today.
Both heads fastened.
Test ran the oil pump with a drill and oil was flowing:)
A silly video for those interested here:

Test fitted the headers, and boy they look good.

I have lightened the fly wheel slightly.

But, does it look like s5/6 perhaps?

Which brand of exhaust manifolds are pictured?

These are headers made by Cavalitto in cooperation with Umberto Maglioli back when he was alive.

A new issue:

I think I have the wrong combination of pushrods and lifters.
The pushrods seem to be too long, as I am unable to adjust the valve clearance.

The lifters are the type with hole on the side, and the pushrods are approximately 22,5mm.

I think I should take perhaps 3mm of the pushrods.
But, whats the best technique to do this, and in which end of the rod should the shortening be done?

I recall there are shorter and longer ones. We heated them up, pulled one end off, cut the 3mm. (~⅛”) and reinstalled the ends, maybe soldered. But don’t recall which engine used shorter vs longer.

As can be seen in my 'flaminia' thread, when I removed my push rod ends, metal fatigue became apparent in the rods, so I had some new pushrods made.  Thanks for the 'header' information image.

Thank you Geoff and Richard!
I´ll do some further investigating today.

Some heating and the lifter end of the rod came of quite easily.

I shortened the rod just shy of 3mm in the lathe, and added a drop of green Loctite before pressing the rod back together.

The shortening gave me a good amount of room for adjustment.

I am a little puzzled by your pushrod problem.
Are the pushrods the original ones from your engine Torstein? And have you taken much metal off the face of the block and the cylinder head faces?
I am assuming you havent fitted non-standard valves.
Chris

Yes, I am a little bit puzzled myself.
An explanation might be that the engine is a bit of a mash-up of different bits and pieces.

The engine block is number the 4497, which I believe is late 4th or early 5th series?
The heads (which were 84mm in height when I got them, and has only been lightly skimmed ) is stamped 18.2.58, which I think would be a 6th series date?
The lifters are the type with the hole up on the side, which is a later kind?

-the  pushrods came with the car , but it might not have been fitted to the engine block , perhaps only included with the sale, as the contract stated that the car should be "complete"
-I have not taken any metal off the block, and only minimal skimming has been done to the heads
-the valves are new valves, sourced from Cavalitto

I´ll add some pictures in the next post

Some pictures

…the valve seats were refreshed, so the valves sit a little bit deeper I guess.
This combined with a light skim of the head might add up to be the cause?
