No I hear what you're saying, I'd imagine they would be sturdy and for one to snap while there is hardly any force applied is just kooky. That's what I meant when I said it was a crap shoot, so I guess I used the wrong term haha. Yeah, boinger engines, who needs 'em?! lol

What all did you get done? The irons, housings, rotors and e-shaft or was there more?

TitaniumTT 01-26-2011 03:14 PM

Ah, yeah, I see what ya mean... I was likening it to Glenns experience with the 8 shaft.... wierd shit for sure, I guess, I dunno.... he's really opposed to it, as I can understand. I just wish someone could say definitevly one way or another.

TitaniumTT 01-26-2011 03:15 PM

Derr.....
I had the irons, stat gears/bearings, rotors w/bearings, and e-shaft done

I was honestly expecting the carnage to be worse from your description on phone man! But yeah that bearing is TOAST! Housings look slightly worse than I anticipated.

I agree with those rotors being 3mm candidates. Although I have heard too that they seal worse than 2mm? I am not the expert here, sorry.

Well, after taking a closer look at the housings last night, I believe it would be best to change the title of this thread from rebuilding engine to buying completely different engine LOL. There are small cracks next to each spark plug port. So I'm either looking for a good engine with low miles, large streetport, preferrably using the seals I'm looking for...or an engine that needs a rebuild that still has good usable parts.

I haven't torn down my old engine yet, I plan on doing that tonight. Maybe it will still be usable haha.

Engine #2 (original engine)
 
So I tore down the old engine tonight, the engine that was in the car when I bought it. HOLY CRAP this thing is almost flawless! It's unreal how nice it is. The irons are amazingly smooth, the housings have slight chatter marks and the front housing has a small crack next to the leading spark plug port. There was one rubber insert missing from one of the corner seals on one of the rotors. On each rotor one oil ring stuck to the iron as I removed the parts, not sure how much that means, if anything. Other than that this thing is amazing! I'm so happy haha.

I gotta rip my rew apart tonight in hopes of making it to the gap..lol as far as I know it just lost coolant seal's but we'll see.. lol doubt I'm that lucky.. i'd contact goopey for the re-finishing of the housing if it was me.. for 125 plus shipping , you can't beat it.. good luck bro and hope to see you there!

speedjunkie 01-29-2011 01:09 PM

Thanks! Good luck with your results too. Even though I have no idea what happened to this engine to make it go, I realize now that I'd much rather lose a coolant seal than an apex seal LOL.

I've been thinking about sending it to Goopy but the crack goes pretty deep so I doubt they'd be able to save it and I'm worried that their resurfacing might have the same effects of resurfacing an iron and not re-nitrading it, which is what I did to my irons and they are unusable now. Regardless I think the crack is too deep anyway and I'll need a new(er) housing.

Dazed and Rotarded 01-29-2011 08:35 PM

Welp.. a few hours later and 5 stitches it is indeed a coolant seal.. and thank god.. but I did learn a lesson on how shape the side of a housing is lol.. now to get them ordered and installed and we're on our way kido's! That suck's about your housing.. atleast you have that spare laying around..lol could be worse.

Dazed and Rotarded 01-29-2011 08:55 PM

Sorry I doubled up lol

speedjunkie 01-29-2011 11:20 PM

So you cut yourself breaking the engine open? That sucks!

Yeah it's unfortunate. I'm not sure which spare you're talking about, I don't have spares laying around LOL.

Dazed and Rotarded 01-30-2011 12:01 AM

My bad man.. I was thinking you had a spare short block for some reason..and yes lol I cut it to the bone.. I was bleeding like i'd been drinkin , oh well. Live and learn.

speedjunkie 01-30-2011 01:57 AM

No the good engine I just took apart is the spare short block LOL, and the housings in the one that just came out of the car are trashed too.

Holy crap man, well I'm glad you got it fixed up.
