912 Engine Project Part 2

 

It takes some time to have all parts together for a nice build Porsche 912 Engine.

This engine will have it all.....

 

The 912 Crankshaft after polishing looks nice

 

the new lifter where checked for the cambered surface

 

Looks good!

 

The Lifters are all in tolerance but I like to pair it with the rigth lifter bore

 

New JE Pistons, 2g difference that`s too much for me.

I`m a little disappointed about that, because a high price piston like that should be better in tolerance.

Anyway I brought it to 0,2g ;-)  

 

 

AA Cylinder: Measuring the length, the Ø and out of round all where perfect :-)

 

Backlash and axial endplay of the Camshaft

 

Good fit of the Rods!

 

Dial in the WEBCAM Camshaft

The quality and finish of WEBCAM is very good

 

 

Just to compare:

 left 912 Pushrod

mittle JPS custom Pushrod for this engine

and the VW Typ1 stock

 

The weigth of 8 Stock 912 pushrods :-(

That`s too much in weigth and they where too long too!

 

Ah, 202g ligther than stock!!

JPS Aircooled Aluminium Pushrods for Porsche 912 Engine, you have the correct geometry with the rigth length and reduction in weigth too.

 

Win win!  

 

 

 

The combustion chamber after masching!

On Porsche 356 and 912 engines the combustion chamber are not equal you have to fix all

912 Engine Project

When I first had a look on the engine compartment I think, wow, what a nice looking 912 engine .
Everything was in good shape and dry. Rebuild 1000km ago!

Fabian (www.zuendpunkt.ch) had to fix some tasks with the ignition and with the linkage of the Carbs.

The first Thing that wasn`t nice where the Weber Copy from China or somewhere....
Never seen this. Anyway the Engine need an Oilservice too .....

Metal particle in the Oilscreen let ring my Alarm bells

 

Nice 1-2-3 Ignition and clean only outside :-(

 

 

Weber Copies, sad  there aren`t the orig. Solex 40 P-II 4 on

 

 

A Norris 337S was in this Engine, you can see some Flakes on the rightside of the Camgear

 

 

Trash!!

 

 

The Camshaft is totally destroyed

 

 

The Cylinderwalls had deep scratches and they were old, too!

The Dumbass that rebuild the engine use old Cylinders an but new JE Forget Pistions in!

This is like throwing money away....

 

 

 

Destroyed Lifters!

 

 

The Oilpump is rusty

 

The disassembled engine

Even the Full Flow Filter has not helped ...
