Hi All,
Well, by now this is ancient history & probably by now lost on some old 914thread since it's been quite a while since I dropped the engine. At the time, there was a HARD knock accompanied by really low power. As in she wouldn't pull third gear- knocked HARD - but still got me home. I expected a dropped valve seat & maybe even some piston damage. From the looks of these heads - I was wrong all around. Next step obiously is to split the case. I'm sittin' here basically dumbfounded. What could the hard knock - coupled with could the low power - have come from if it's not associated with the heads? I haven't even cleaned the heads yet - & they look pretty damn good. Pistons look pretty good 2. Check out my picz & PLEASE give me a clue.. Attached image(s) |

Looks like she was blowin oil pretty gud....
Hard to say from those pics what might be wrong. Check the valve stem witha straight edge to see if they are all the same. |

Did you check the lifters? Maybe you wiped a cam. Was the mode of failure on mine - lifter fell apart. Nast ugly noises from the middle of the motor and no power... Coulda spun a bearing... You should find out when you splt the case.

Think I found the reason for the "knock". What the hell is it? Haven't split the case yet. Attached image(s) |

Looks like the half of the wrist pin hole from the bottom of that piston. Looks to be missing from the pic but hard to see zakly.
Woulda made one hell of a noise for sure. Also looks like one of the heads hada bad intake leak. One hell of a lot of carbon build up on the piston crown. Smoke a bit did it? |

Ok I have to agre with the fan blade. Going out on a limb here but 99.9% positive that wasn't in your engine. Maybe sitting in between the cylinders. Was your fan missing a blade?

Yup. In fact it was missing 3 blades. Engines been sitting on that wood crate for about a year. When I pulled the head today, I heard a noise. Dooohhh - I assumed that it came out from under the piston skirt. If it had bounced around there would be shrapnel marks - I should think. Still don't have it apart yet. I MUST be wrong. (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) Piston is unharmed. Head looks fine. Amazing how clean they look for as many years they ran. It always ran rich & it looks it. I have no idea the mileage but I can tell you that I drove it most every day since 1998 and it was running when I bought it. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |

So now I have two complete 2.0 longblocks. I had planned to re-build this one for a spare & keep it - but now I need cash to megasquirt my new engine - so the used engine is 4 sale.
Any idea of what's a "fair" price would be appreciated. Thanx, Gary (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) |
