I bought a engine last week that was supposedly a 1.7, but the guy didnt really know for sure. After looking at the case numbers, I think it might be a 1.8?? It starts with EB. I took all of the sheetmetal off to repaint it, and everything is really clean accept for around 1 of the cylinders between the head and the cylinder, it is black and kindof oily. I figure this is a leaky cylinder. Do i need new head gaskets? Or just retorque the head? Where do i get head gaskets? Pelican parts doesnt sell them. What should i do with this? It is supposed to be a fairly low mileage engine. Thanks

What were the values that you were getting on the leak down? Remember they will be a little low due to the engine not being warmed up.

Tell you what I would do.

Stick it in the car and run it till it breaks. Put your effort into the 2.0, and get it built ASAP. Don't put any money into the 1.7 that you can avoid. it will get the car on the road and if it only lasts a season, who cares. If it still runs when you pull it, sell it to someone else.

Thats what some of my other mechanic friends said to do also, so im going to try that. Its not like it is that hard to pull these engines out, so its worth a try. The numbers on the leakdown were in the 80% leakage range. It was hissing out the valves really bad. Once the motor runs and warms up a bit, hopefully they will seat better.
Yeah, i want to focus my time and money on the 2.0 and build a 2056 or something bigger maybe.

Once I had my parts in hand and the balancing done, my 2056 was built in a week. granted, I took the week off to build it. But the point is that it does not have to take a long time.

And I'm a total noob with building motors.
