Great link, looks like lots of good info there. THanks for that.

WOuld love to get my hands on the BugMe DVD as well if you are finished with it.

Still looking at getting the engine moved down to my basement and onto a stand, unfortunately, I threw my back out a few days ago, so that is causing delays.

Eric I think I have a extra Bug Me DVD i can give you . The late Bob Hoover's Blog has a great deal of practical air cooled motor information.

Slow going, but I did receive the rebuild DVD in the mail yesterday. Thanks NCRider!
I'm still trying to get my neighbor to help with moving onto the engine stand, then i will send more pictures. Head and cyclinders, etc are in plastic bins and the shortblock is still sitting. I thought if I got all of the extraneous stuff off that I could move it myself, but its heavy and I dont think I can get it to the basement alone.
Everything is set to go, but life keeps happening...

Have you found anything obviously wrong? IIRC it was #3 that had low compression. Looks like your boy is enjoying the process (IMG:style_emoticons/default/smile.gif)

Pistons are off! How do they look?

The clips holding them on were very hard to remove. Splitting the case open tonight! Attached Image

Go slowly on splitting the case. Lots of hidden bolts. don't get too physical and try to wedge it apart. If it does not come easily, you have a nut left to get.

If you had low compression, were the rings stuck on that cylinder?

What about a photo of the heads? My problem was obvious. One of the valve seats had broken and gotten into the combustion chamber and bounced around, ruining the piston and the head.

I will post detailed pictures of the heads tonight, been meaning to do that. I think the internals may be OK, but I want to split the case open out of curiosity, if all is well, I will just leave it alone.
Can you elaborate by "rings stuck on the cylinder"? Is there something I should look for? Will post pictures of those as well.

Thanks

Rings stuck. I was thinking you could have a low compression cylinder. Maybe a ring problem. I have seen rings that have come out of their channel and bent. Maybe a ring broke and did not seal properly, or stuck to the inside of it's channel and did not touch the wall of the cylinder.

Any reason to not show compression.

Blake took the thermostat and oil pump cover off last night before the magnets we were going to use to remove the lifters got all of his attention.
This looks like a Type1 oil pump to me, am I right?

Also, can anyone identify these pistons from their markings?

Thanks, slowly making progress..

Something doesn't look right. All the 1.7s I've rebuilt have domed pistons. The pistons pictured in this thread appeared to be "dished" or lower compression. Could hat be a bus or 411 engine?

I noticed that too, could be bus pistons for sure. I've heard of them being used because they are cheap.

We got the case open!

Confirmed that it is a 1.7 engine, but case has a bronzish tint to it. Wonder if it was recently rebuilt or mucked with because everything has come apart pretty easily. (ie bolts not stuck, etc).
Lots of oil and dirt on it though, so I need to figure out to get this thinged cleaned up. Anyone ever take their case to the car wash and use the pressure washers there?

you guys are doing a great job.
Over here: If I would take a oily case to the pressure washer station I hope I do not get caught for environmental hazard violation.....
Keep up the good work ! Looking forward to more updates !
