1975 Porsche 914 2.0

1975 Porsche 914 2.0The latest project to arrive at the Flashback Racing garageĀ is this 1975 Porsche 914 2.0. The previous owner had finally given up on trying to make the repairs that this mid engine German roadster needed. We found it happily running along on 3 cylinders with little or no compression in the fourth chamber. Time for a complete mechanical rebuild. While we are into the car that far we will add a fresh coat of paint and look to have a road ready 914 in the spring of 2015. Here is how the project is coming along:

June 21: We acquired the Porsche and took the following photographs.

June 28: The dismantling process begins. We pulled the engine and transaxle and removed all the engine tin and exhaust system.

Here is the 2.0 engine, transaxle and exhaust as it appeared upon removal from the car. The only issue we observed was a massive use of silicone sealant on and around the pushrod tubes in an attempt to stop or slow down oil leaks. We next separated the engine, transaxle and exhaust system and removed all of the engine shrouding placing the engine on an engine stand for complete disassembly.

In the weeks that followed our engine teardown revealed no major issues with this engine.

Cylinder heads appeared to have been recently rebuilt.

Pistons and liners also seemed to be rather new. In fact it appeared that the non firing piston and cylinder had never been up to operating temperature.

We complete the tear down of our 2.0 Porsche 914 engine. Here are the engine case halves cleaned, detailed and ready for reassembly. The crankshaft mic’ed out fine and the bearings all looked good. This engine had almost no wear on the previous rebuild.

We also cleaned and polished all the other engine components prior to starting the rebuild.

We then ordered new pistons and liners, gasket set, intake and carb set, and sent the cylinder heads to our favorite machine shop to be checked for cracks and valve seating. The rebuild process will begin shortly.
