Some of you may have read my earlier pleas for help when my engine suddenly would not start. I thought it was the FI but after following the advice of members I did a compression and leak down test and discovered Zero compression and 100% leakage on #2.
With a heavy heart I pulled the engine, the pictures say it all.
I had the heads rebuilt earlier this year and have not done more than 300 miles. (IMG:style_emoticons/default/mad.gif)

Some questions:
what else needs to be checked for damage?
I need some new heads does anyone have some ready to use heads for a 75 2.0?
I guess the piston is also unusable, if I get some aftermarket P&C can I just install them without replacing the bushings on the connecting rods?

I guess the summer will be over before the engine is fixed.

Agree with taking them back for a refund, but NOT work/rework. If the person repacked parachutes, would you go back ? Not likely. Get as much money back as you can.

The used heads you have coming have many advantages to yours reworked (by anyone) as many have already suggested. I want to add my 2 cents:

The used heads have already been thermal cycled many, many times and are still OK (assumption here) based on the seller and you agreeing they are "good heads". So, the chances of a seat failure are unlikely if all other aspects of your engine running are as they should be. This option for you seems like the best based on the information you provided to the Board.

Here is my 2 cents: Remove the valve keepers and spring(s) from each of the four exhaust valves prior to installing. Push the exhaust valve open with your finger about what the cam would when installed. Then, rock the valve face perpendicular to the valve shaft back and fourth, then move your fingers 90 degrees and repeat. If the valve rocks about 3 mm to each side, you need guides and will most likely have smoke when you lift as the intakes will also be worn only not as much. Installing Silcon Bronze guides and hand lapping the valves (your self) will buy you some time with the used heads. If the rocking of the valves is less than the above, you are good for many, many carefree miles.

Spend the time enjoying your used heads saving to have your original heads done up right by the folks I and several others have recommend as the heads are the key to the 2.0 engine long life and performance. Spend the money on heads as the stock bottom end is nearly bullet proof when taken care of.

Hope this helps. CJ
