Project FC 500 mile update..
Dude I just re read all your re rebuild threads and I am clearly missing this HUGE gap you are talking about? I dont see it in any of the pictures and I dont expect you to see good compresson for 2000 miles! Plus your using used housings, with new seals that have to wear and seal.... so give it some time!

I agree, it takes a good while for compression to go up. (Break-in)

I looked through his old threads and that pic didn't seem to be in any of them, the one he showed us. But, I did find this.
It was hard to tell but this looks like the gap on one of the rotors, not sure though.

Original image.
Don't do it felix! I'd say put it back in and give it time.
That's just dirt on the seal, dDub. Look at it closely, there's obviously something there. I'm sure that even a n00b would realize that a gap like THAT existed! That's gotta be damn near half inch!

Ah yah probably, my eyes are kinda shitty. But he did show kahren and I a different pic last night that had a rather large gap, not quite that big but still large. I told him to leave it, but Kahren said that's what was causing the compression problems, if that was indeed the gap that the picture portrayed.
If you had that big of a gap it would blow the oil seals causing major blow by out the oil system. You would have like 80-80-50 compresson. Trust me. When I cracked a side seal, same thing happened, car smoked like hell, had major blow by, and just died.
Yes that's not the actual gap... my bad chalk it up to my shitty eyes.
But like I said, there was a noticeable gap that IF it was real it COULD be the cause of his problems. I told him not to worry, but he didn't listen. Might also have been because he reused his side seal springs for the compression or blowby, but that's up for debate too.
Also, he was having shitloads of blowby early on and had to change the oil a lot sooner than normal for a rebuild.

ok, the engine is in the cellar, waiting to be poped open.. i dont know if im gonna do it tonight or not....ill post the pics later of the side seal gap
Felix, even though I'm talking to you on AIM, I'm going to post this for everyone playing along at home. If your problem was blowby on ONE sideseal, then you'd be seeing an odd compression, such as 80-80-50, instead of an even 90-90-90 or whatever. And I doubt that ALL 12 of your side-seal springs are worn enough that they would give a perfect, across the board measurement anyway. You'd see 84-90-74 or whatever..
And now I know you didn't do the compression test right.
