I'm in the process of re-assembling a 1600 TP into which I have fitted a new set of rings.

I've nearly completed the job to discover that I failed to fit those two small pieces of tin ware that fit under the barrels on each side and which clip to the head studs.

I can't fit them now as the push rod tubes are in the way.

I'm not looking forward to pulling the engine apart to fit them.

Will it matter if I leave them out?

The engine will go into a buggy, so not all of the other tinware will be re-fitted and the engine will be sort of out in the breeze.

Is it critical that they are there, or is it O.K. to leave them out?

Yes it does matter as they direct air.

What I have done though is to drill a hole in it about 6 or 7mm in dia
hammer the clips flat and slide it in to where it should go.
Them get a LONG 6mm bolt with some LARGE washers and feed down from the top.

Not the best - but it is an answer that worked for me

without those air directors air won't go round the cylinders
and Yes its easy to leave them out and they should be made to slide in afterwards..lol
do what bizzare said.. save You a lot of work..
when You look at type 3 cool tin.. which does the same job.. they are very different..
but something does need to be in there

cheers

Fit them and the lower sleds (even in a buggy) or your barrels will not stay round due to uneven temperatures. Out of round barrels = excessive blow-by high crankcase pressures, leaking oil, shorter engine life, etc etc etc......

They direct air around the cylinders

otherwise all air is lost...

When You said buggy I was thinking an offroad buggy

but if its a road car and going to do a lot of miles/klms
I would undo the work You have done and put them in

they may not look much but essential for the cooling of the cylinders otherwise the air will just flow past the cylinders..

and the bottom plates need to be there as they are air directors also.. they also direct air over the push rod tubes which help cool the oil flowing in them..

cheers

Thank you gentlemen.

I went to the trouble of removing the heads and pushrod tubes and fitted those small plates in their right positions.

As the engine was on the bench and all the bits were clean and well oiled it was a very quick job to do it.

Having thought about it, it is obvious that they cause the air to travel sideways and cool the barrels, otherwise the air would just rush past, between the barrels and away without doing much cooling.
