My first type4, probably 2056

Really hard. Ring gap was 0.014-0.015". No spark plugs. It only started to be this hard once I added pistonsand cylinders. And I put a lot of oil during assembly. I'll try to make a lever to bolt in place of the pulley and give it a few spins. Now I stopped it at tdc, maybe that has something to do with it. It's so much eadier on a type1 with the big pulley bolt and a wrench/spanner.

I would have a hard time turning a motor by hand using the pulley or fan in the state you describe.
Turn it using the flywheel by hand - no problem, do it all the time.
(ring gear chews hands).


I use the flywheel by hand turning against springs, duals even, setting up geometry, and i'm no brute.
Not with plugs in, though.. no way.

Hope this helps.. X2 on checking ring gaps.

I rushed to conclusions, engine turns properly. I installed two long bolts on the pulley to hub holes and used a long bar to turn it. It freed up right away. I think the problem was I left it at TDC, where it is a bit harder to start turning it. Now I can even turn it by the pulley with some effort.
I do not have access to the flywheel, it is mounted on a stand made out of a type2 gearbox bell housing.

As much as I wanted to start the engine last year, I was too lazy to paint the engine tins and finish it. Meanwhile I started the rebuild of the car (time for bodywork, paint and interior, the rest is good). However I made a small improvement to the ITBs, buying the rubber boots destined for a Yamaha ski jet or snowmobile (I think), SPI 07-100-15. I enlarged the mounting holes by 1mm eachh and now they fit really nice. And this way I can easily swap the complete FI to the type1 if needed.

Hello, I’m planning my T4 FI build and winter what throttle bodies are you using and where you sourced the rubber boots.

Hi, the ITBs are off Honda VFR750, 2001 IIRC. I bought two sets for ~30$ each just to have two accelerator wheels, and they came with everything: injectors, sensors, rails etc. The rubber boots can be found on ebay, search for the code above. They are ~10$ each.
