=====Engine + rebuild after engine damage=====


{{ start:2-tr6:motor:img_20170415_151328.png?direct&400|}}

Kilos of scrap iron...A lump of cast iron that is said to come from a tractor...\\

But that's only partly true: The four-cylinder engines of the early TR (2-4a) are derived from an engine that Triumph-Standard built for Massey-Ferguson tractors...

The 2 liter six-cylinder of the Gt6/Dolomite/Sedan was a completely new design using identical parts e.g. with Spitfire engines (connecting rods etc.) and was brought to 2.5 liters for the TR6 / Triumph 2500 with more stroke...

This made it extremely long-stroke, lost liveliness, but increased the torque.

===="Wet oil"====

Supposedly an English engine is empty if no oil drips out...
But there are also said to be dry "specimens"...

It is usually due to a lack of knowledge, bad spare parts or simply wear and tear that oil leaks out.\\
Worn piston rings/cylinder liners increase the internal pressure, poor quality crankshaft oil seals then allow the oil to escape at the front and rear. A warped sheet metal oil pan (screws too tight) does not make it any better.
The same applies to the [[start:2_tr6:getriebe|Getriebe]]
====Oil pan ====
Can be straightened:
straighten warped screw holes: suitable nut and a screw "from behind" and then straighten the contact surface with "light blows to the back of the head":

====Head====
In my TR there was an early carburetor engine...not bad in itself...but unfortunately the intake manifolds do not match the hole spacing of the Lucas intake manifolds....

So: Replace the head....

The "new" head comes from a TR250 was "optimized".... exactly like the rest:
Valves, guides, springs, camshaft, rocker arms, rocker shaft etc.

Result: the car runs >200Km/h (GPS measured)

====Reconstruction after engine damage====

My son called me with the words: "First the red light came on and after 2 minutes the engine stopped..."
And I knew immediately: "This is going to be expensive..."

Oil pump damage -> crankshaft damage (main bearing + connecting rod)

So I got the big package: VW pistons (77.01mm), H-shaft connecting rods from BarTek, bearing shells for the camshaft and everything was finely balanced...
Compression ratio 9.79:1

With a paint scale from the neighboring car paint shop, adjustment to 0.4 grams! :-)
