    • Parts didn't fit.
      Verified Purchase

      The 'belt' that turned the pistons didn't fit right. So the pistons would move, but the fan didn't. Not worth the money or the time it took to figure out the item doesn't work correctly.

      It was a great idea, but very difficult for a 7 year old to build. My son loves engines. We built it together. The timing belt was warped, so it never worked.

      Verified Purchase

      Got this for my son for Christmas. It's a very cool idea, but cheaply made. There were missing pieces and some of the pieces broke easily. Not worth what I paid for it.

    • Model Engine
      Verified Purchase

      The engine is fun to assemble when you have all the parts needed. My recommendation is verify that all parts are included before starting the project. Maybe not such a good idea to get this toy from Overstock? Then send one email to NSI. So, far NSI International has sent us the first part and we have requested the second at the time of writing this review. My ten year old is able to assemble the engine with just a little help. There are a couple of mistakes in the instructions. On step 18, follow the sequence A,B,C,D,E,F,G and H for the camshaft but don't try to match the orientation of the parts to the drawing. Instead, A & B, C & D, E & F and G & H will point in opposite directions. Also, on step #19, ignore the drawing showing that the camshaft parts have changed sequence in that step. This was confusing to my son.

    • parts missing, poor quality brittle plastic-cheap

      Camshaft pieces were missing. I had all 8, but instead of all being different I had a mismatch of 4 of the same, 2 of the same ect. Many pieces already had cracks out of the box and while installing screws usually cracked and not from over tightening, like half way in they would crack. Pieces were badly molded and featured a lot of parts needing deburring before they could be assembled, Instruction illustrations were very poor and incomplete leading to confusion on many steps and having to look at all the other steps to see proper orientation. Several times these were even inconsistent. My daughter got frustrated with this and rightfully so. I'm a mechanic and I think it's garbage. Buy the visable V8 for another $10 it is a lot better made. Still waiting to hear about the missing cam pieces, probably be thrown away....beware.
