It's alive, but not happy

"But it's a DRY heat".....snap some pics and post up in this thread to help the poor bastiches that follow you. Curious about your "early mount" vs. late. My AC also still functional down here in the soggy summertime SE.
 
Can't get a decent pic right now. Main difference though is the lower compressor mount doesn't use bushings, everything is hard bolted to the accy. bracket, instead of to rubber bushings.

Funny thing is, the AC worked fine until the line came loose at the muffler under the washer bottle, a fitting that had never had a wrench on it before.

I'm still having a hard time grasping the fact I've had 2 compressors do the exact same thing, and nobody else has reported this as an issue.
 
Yeah, heard about that after I'd put the current compressor on, didn't want to discharge it.

I need to dig up the newer plumbing and remove it this time around.
 
Years ago I swapped dead rubber for poly, then swapped to the hard mounted bracket, now back to rubber. Never went billet, won't either.

Nobody ever really thought the AC compressor would cause false knock sensor issues.
 
No one really ever has had issues like yours with KE going that rich and causing issues. Well at least no one paid enough attention to it if they were.

My knock sense (good or bad to each thier own) would almost always go off on 91oct over 5000rpm. On e85 over 6200+. I always figured the motors were just loud.

I think we have a winner....

Too many 'ignore it and it'll go away' types, not enough 'that ain't right, what's actually causing it and how do I fix it' types.

I am the latter type, thankfully.

Didn't really have an issue on E85, but I'm not sure if it's because it wasn't going into KE, or if it was and it was just using all that fuel but not bogging down as much, so the issue wasn't as noticeable. I may try and cap the lines and run without the compressor for a month, see what it does, but I suspect I know the answer and will like the performance...
 
Well, that was unamusing.

AC compressor removed. Test drive...11-12psi, bam, back into knock enrichment.

Next plan, 3g of E85, see if it does it. If so, I'll chock it up to crapgas. May try running Chevron as well, instead of 76, see what it does.
 
3g of E85, same tank of fuel, rips to 18psi, no fuss, 75* ambient temps, 11.2 AFR to the limiter. Guess it is indeed just a fuel quality issue. Damn.

Got the truck in town for the next 2 weeks, then I'll reinstall the compressor, get the AC running, then the MS swap down the road.
 
Haha looks like you american guys now got the same **** to deal with when it comes to get a pass for your car.. :)

/Edit

Can it be possible that the billet bearings for the generator could cause the same problems?
 
Not likely. I don't have them on here anyway, just standard poly. Also the generator has a constant load on it so there's less chance for things to rattle compared to the compressor.

As for us, well, California has always sucked for being able to have a fun car AND keep it licensed. Whatever, just means we gotta be more inventive. :)
 
Damn, that's a new one. lol

Thankfully that isn't my issue. Between the Bosch 100A, then the Denso 100A, then the Mechman, never had an issue with that side of things.
 
Just a little update, pan is coming off AGAIN tomorrow. Oil pressure recently dropped .5b hot, no reason why. Hasn't run low, hasn't lost pressure. Borescope pic looks like the transfer tube seal again. Pulling the pan, new OEM seals, steel washer to go behind them as well. Plan to pull #1 rod cap, see how the bearing looks. Hopefully it's fine (only #1 has really failed to date), if so, it'll get buttoned back up and on the road again. Plan to drop down to 10w40 instead of 15w50, see if it helps build pressure faster on cold start, also see how the pressure does. Seems to run happier (from memory) with the thinner oil, plus better mileage.
