After a tear down of my 2.0l engine I started the build up to the 2056 big bore upgrade. Having a Bridgeport I started with the (5) 3/8 oil galley plug on the block halves
Drilling a hole in the plugs and a slide hammer to remove the old plugs then started the installation of the new pugs I was able to order from Type 4 store.

FWIW:

While waiting on the next round of parts and machining....

This 1.7 to 2.0 to 2056 upgraded started with a little knock at idle. With some hard street use the noise/knock increased. In a time, over 2 years and 20 to 25 k miles later I found bearing babbitt in the oil strainer.
Thinking this was a rod knock that I was unable to isolate but pulling the spark on the rod with the noise. And the fact I now KNOW it was a bearing failure at this point the engine was pulled an retired and a stock 2.0l with Factory Djet was installed in its place

This replacement engine runs good and starts in all weather on first try but the fun spirited driving was missed, so the tear down started on this 2.0l weber carbed track engine and this turned out to be the only failure noted so far




The Cam thrust bearing shown above has no babbitt material on the timing gear side. The cam was walking back and forth with each change of engine load. Under power it seemed OK. So while in there the plan to swap cam and bearings, this now turn into new pistons and rods. Now a full 2056 with rods cylinders pistons, lifters and heads. fuel by Kerry Hunter headers and Evo ii muffler and webber 44 IDFs. And to help ensure this failure is not going to happen any time soon an double cam thrust bearing is already in the purchased parts box.
