Well,

Long story short.....

Had a "friend" help me rebuild a 944 engine. At some point (I was not around) he put the cam tower on and did not set the cam to TDC. When he attempted to start the engine, it bent valves.

After removing the head, there is noticable scoring on one cylinder. At this point, the "friendship" is over and I need to get my car out of his place.

When the engine did not start, a compression test was done and that cylinder did have decent compression. Also, we put some assembly lube around the top of the bad cylinder's piston, and it did not seep below the rings.

Would anyone attempt to use this engine? I am concerned that if I do not help my friend re-install the engine and subframe, I will not be get all my parts back, (he's got parts from ton's of cars scattered around) yet do I go through an engine re-install with scoring the way it is?

Again would anyone put this engine back in the car and run it? It is a race engine, and a little smoke would not be the worst thing, but could I even get a season out of it????

I think I know the answer, but it makes me ill......

Thanks!!!

Post a pic. Lots of engines have "scoring." Most are just visible lines and don't really matter.

Can't take a pic... motor is at at friend's house....they are bad enough that I can feel them if you run your finger over them.

There are a few threads on this. (Search recommended)

Worse that these?

I'd have to say the scrathes are worse then those shown in your link. When the head was removed, there were mettal shavings in the oil filter and surrounding area. When the head was off, we did run a little assembly lube around the top of the piston on the bad cylinder, and it did not leak past the rings...but not sure that has any meaning at all.
