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.

Interesting that you didn't see low compression & leakage for cyl #3 as well during your initial testing.
Were the heads assembled when you received them? ... or did you reassemble them? Wondering what the 2 valve stems and guides look like ? While 2.0L heads do flow better, they also have a history of dropping seats. Did you notice high engine temperatures anytime during that 300 miles? |

I did not do a compression/leak down on # 3, I pulled the engine after seeing the result for #2 The engine never ran hot and the heads were delivered assembled. I do not want to dismantle the heads to examine the vale guides etc before I return them to the shop. |
