The 1972 914 I bought is supposed to have 103mm Nickies (by LN-Engineering) with JE-forged pistons.

The car caught on-fire, so I had to remove the engine. After doing so I find that the cylinders are magnetic. Nickies are made from Aluminum, so this is suspicious.

Is any of you able to recognize the make of the Cylinders in the below pictures. There is one picture with some marking on it. I do not want to disassemble the engine any further then needed.

I only own this car for two weeks now, but going up a very steep learning-curve. very soon I will be able to help others. But for now I'm only asking questions.

Br,
Hans Jan

Sorry to hear of your car. In regards to your question, I think you already know the answer.

At this point, I'd be willing to bet the pistons aren't JE's either. But no worries. That's why we're here. I saw the video - that sucks. You got taken by the previous owner, but you're certainly not the first one. It can all be rebuilt. Of course it takes more time and $$ out of your own pocket, but we'll help you figure it all out.

Even though this is bad news, you guys are the best.
I have looked at the AA-website, but cant find the machine size for the register. If this register is bigger then 108.5mm the Nickies won't fit anymore.

Anyone knows the register size for AA-cylinders 103mm?

The orange silicon tells a lot about who built this engine. You don't want it there.

You will have to disassemble the engine to find out what you have. If it is running good just tell everyone you have a mystery engine.

Nickies are machined, those are cast cylinders, I hope you didn't pay for Nickies!

And if you sell it don't misrepresent the motor like the person you bought it from

What video? What did I miss? Maybe not the engine it's supposed to be but if you had a fire you have way more on your plate now. If that engine runs good don't worry about it. Sort it out after you fed the car repaired. (IMG:style_emoticons/default/welcome.png)

Those aren't 103s.
The case registers are probably unmodified.

It might be worth while to have a long talk with the previous owner who miss represented the engine! Not only the piston cylinders not as advertised but you never never use RTV in building a 914 engine.

If you paid nickies coin for that you have been hosed.
I'd be just a tad pissy about it.

RTV is OK under the cylinders. Also a little RTV rubbed into paper gaskets (no excess) is OK as well.

No, it's not ok at the registers. It means that when you torque the heads you actually measure the RTV elasticity. This will allow vibration in cylinders and heads worn the cylinders and create leaks when the RTV cracks.

Over 25 years and hundreds of T1, T4, and /6 engines built, except for one cam/lifter related, no failures.
How many engines have you built?
