Type-4 2.0L details – and a service run

The time leading up to the holidays provided a chance to run my completed 2.0L 4-cyl engine. Originally, this engine came about as the future power plant for my 1971 4-cyl car which remains un-restored to date.

The engine had been sitting for a while and per advice of several of my 914 mentors it was time to fire it up. Total run time on this engine was under 15 minutes till this point.

We decided to take off the sheet metal and vent ducting to gain better access to plugs, valve covers and head studs. Our intent was to get the engine warm throughout and then perform a valve adjustment  as well as re-torque the heads. Wes of H&H who built the engine recommended these two actions at this point.

The engine came to life immediately; no hesitation. While it is a subject of some debate, I do like the exhaust note of the Bursch muffler on this 4-cyl quite a bit.

Besides checking the oil level before we ran the engine, we checked the oil pressure with a gauge to ensure that the high melling pump was operating as it should. Oil pressure was great, and underneath the valve covers there would be a fine film of oil over all the rocker arms and a small puddle by each tube after the run.

One thing we quickly noted was the alternator belt was wobbling quite a bit. After checking the fan in a lathe, it became apparant it was not perfectly circular which caused the wobble. With so much attention to counter-weight balancing the crankshaft with pushrods it made no sense to have this rotating mass out of balance. Rich dug deep in one of the caves and returned with an early fan which was very circular.

There are so many nice parts on this engine!

We added some 30 minutes of run time this Christmas – the engine is now back in the corner, waiting to be used at some point. It is such a nice engine and I can’t believe the amount of thoughts and work that has gone into it.

Thank you, Rich & Wes!

  1. Nice engine , I have a very clean 73 1.7 that I am looking to stroke or find a 2.0 case and build @ the least 125 hp . Any suggestions or possibly know where I can find a 2,0 liter case ( with or without crank and barrels(pistons etc?
