    Heyall,

    I been gone again for a while. too much "stuff" happening in life nowadays. Cant even say anymore that I can fill my tank for 20 dollars or so. The whole 10 gallons I burn costs over 40 now ><. Still beats what the wife has to pay for her "full fill". It was nice to cruize 50-55 to work now without all the lights and turns and doing just under 30 miles / gallon. Wish I could do an electrical swap now. Been thinking about that for a while. The kits for it are out there.

    But as usual, still having issues. Now I getting high idle. False vacuum somewhere probably, not been able to find it yet.
    Hope I can find enough time and funds to work on this and get Macro usable again.

    Fushy.

    Cost of living is getting out of hand. And fuel prices are a killer. Your IACV may be gummed up and causing a bypass into the intake. Good to see you are still joining the fray so to speak

    Heya all,

    I have not quite figured the high idle out yet. I did something and for the life of me I do not remember what but its less now.
    She still running and taking me to work and such.
    I did finally get me ass in gear and fixed my driver side of the bench. The steel rods on the springs broke and I have been sitting on the floor board for over a year now. Sure makes the little pick-up feel like its sitting higher on the roads now lol.

    Had some interesting storms here before the heat settled in in Texas.

    Tree in the drive way lost its top ( good thing it did not take the power lines with it ) and fell on Single and the wife her car. No damage to either vehicle other then saw dust and such after I sawed my way through.


    With Macro still parked in the back and this heat wave going through I am not doing a whole lot.
    I did get to measure the actual radiator temp after yet again having done something I do not remember. Temp at the radiator entry is the same as the thermostat temp that I installed. So all good there. Cluster gauge is also not as high anymore as it was and only reaches the same is half way it did in the winter before at the heat of the day but stays around a little over 1/4 in the morning now.

    I am still alive and kicking out here. Hope you all are as well out there safely driving around in these little monsters!

    Fushy.

    I really have not posted anything for nearly a year now. Time is passing me by too fast and sure makes me feel like I am getting nothing done anymore.
    Single still runs and takes me places. Though currently with the heat I am also driving the other one.
    Found part any maybe cause of the high idle. Seems to happen only when the purge valve opens and if would seem that one of the hoses under the tank or the filler neck is the actual leaker. Not been in the mood lately to pull the tank again to find the holly hose. Smaller tank and easier to pull then the Macro but still. Too lazy I guess and glad also its not the tank under the wife's Ford. That thing has too many hoses and electrical sensors and stuff on the harnass near the pump.

    I have seen others with issues ordering clutch cables in them being too long. Right now I have the new cable ( I snapped mine again ) attached to the first bolt on the hook plate at the transmission.
    Previous owner had the transmission redone and also put new clutch on it. Clutch with too strong springs on it so I ripped the firewall. Gots a nice hole in there now. I bent back what I could and re-inforced the whole area. Inside the cab there now is a metal place with a hole big enough for the cable and the original presser holder to stay put. In the engine compartment I placed a metal bar at the top that sits just under teh break booster.
    Break booster has some very nice inforcements around it. Wish they did this around the clutch cable hole also. Below the clutch hole is an other metal place and its all bolted together. Put some 5k or more miles on this work now and its still holding.

    Is there anyone that knows what the actual length of these cables is supposed to be for these pick-ups?
    Also is there anyone that had converted over from cable to hydrolic. I was able to find several parts that could possibly do this but the transmission part seems different.

    Hello Fushy
    My clutch cable broke about 1 1/2 years ago ordered the Rock Auto 4x4 replacement compared its length looked same but it ain't as good as the original COZ there is no flat washer for the star adjuster ring to push against NOW the star ajuster pushes against the firewall rubber gromment which seems to undue the adjustment ~ I gotta keep readjusting tighter to keep from grinding gears ~ channel lock pliers can reach the adjuster so I keep them in the truck ANYWAY something aint right with these aftermarket clutch cables LENGTH problem maybe ~ I am aware there are two different lengths RWD & 4WD

    Take care in Texas Bro

    Welcomen back to the never ending trouble.
    I did find something positive with it though so not all bad. Single is sort of stranded in the drive way again.
    What seemed like a nasty oil leak at first when I Was at work. Proved to be a coolant leak when I got home and put the endoscope between the engine and the firewall. Not that its any better but this would seem easier to fix. Well sort of in the short way ot saying it. Replace plug with new one leak fixed.
    On paper yeas. The expantion plug ( of freeze plug ) is done for and there is about 2~3 inches of space to pull it out and press a new one is. Not quite as easy anymore now. I checked the other pick-up and its leaking there also so I will have to replace them on both.
    Does anyone here know where all these plugs are on these engines?
    For obvious reasons I know of one . I remember somehting from twin cam head replacements that there is an other in the front behind the timing covers and I think I saw one near the starter motpr somewhere.
    Rock auto sells a kit that has 9 ( nine ) of them in it. Do these engines really have 9??
    Shop manuals do not show there locations at all.
    No idea yet either if I can replace the rear one with a simple rubber bolt on one yet either.

    Thx ya all :D

    Well, I guess there is a good comparison here for what is happening around me and has been for a while now. "There are no happy ever afters, just new battles." Miss Connally Dock worker guild rep. Babylon 5 season 1 episode 12.
    Sure would be nice to have better preparations for some of these "battles" though. Taking the rest of the week off to figure out what to do. Both gals stranded. One with coolant issues and the other with susspension. Aside from that I also have other issues at hand in and around the house. Wonder what that movie was where the husband cloned himself to get all the work done. Kind of feel like I need an other dozen or so of myself about now.

    Minor update for the work on this little gal so far.
    I dropped the transmission ( after draining the oil ). Currently is still laying sort of stuck under the frame. My jack stands are not going high enough to take it from under there. Need a new boot on the stick. found a possible replacement from an ATV. shall find out if it fits when I receive it tonight.
    Removed radiator fan and shroud along with the intake and exhaust pipe connection to the Cat.
    Now for the "fun" part. I lifted the engine up, removed the mounts ( what a pain to get to these ) and pushed the engine forward till I got stuck with the exhaust on the cross member. Then I dropped the engine as low as it could. This provided me with only just barely enough space to get to the freeze plug that broke. The one closest to the firewall the highest one also. Replaced with a brass plug now.
    I got the engine back in its mounts late yesterday and put the rest all back around it ( intake, fan, .... ) Exhaust I have yet to work one.
    I was hoping to find the vacuum leak ( lean running cause ) in the fuel tank. Thus I removed the tank also. 5 gallons of gas left @ 280 miles. 13-5=8 gallons. Yep lean running I can do almost 30 miles per gal. Sure makes the engine run hot though.
    Still though, checked the gas tank and seems the leak is not there. I cut my own ring for the level sensor 6 years ago and this seemed still intact. Still replaced it though.

    Hehe, I should post some pics later on how the pickup it "hanging" in the back with straps and 2x4s. I need a better space and tools for this :D

    You all stay cool out there.

    Well, I put it all back together. Did the finishing touches and some covers yesterday.
    Lean running / high idle is still there. Maybe I should hook the loggers and scope on it again and try to find out what sensor may be messing with me.
    Took a little drive out to get some free beer ( nice to have a few good contacts with some local breweries ). I had issues with the clutch though. Normal driving was ok but trying for fast accelerations did not work. Clutch slipped. Drove to the brewery and before I got there it seemed to have gone away. After my shopping I drove home passing the speed limit a little and had no further issues with the clutch. Not sure what could have caused that. I cleaned everything up with brake cleaner.

    What a pain is it out here to not have your own wheels for over a month.

    Could be some oil or coolant leaked onto the flywheel or clutch somehow, which eventually got baked/scrubbed away by driving.

    If you have a cable-operated clutch, check the cable freeplay at the adjuster. Pull the cable housing towards the front of the truck and screw the star nut adjuster snug against the rubber bushing at the firewall -- or if it's already tight, back it off until it's slack, then make it barely snug again. Press the clutch pedal several times, then pull the housing forward again and back off the star nut adjuster until there's a gap of 15/64" (6mm). Hydraulic clutch is a bit trickier, will get into that if you have this.

    Owshy That is a shame Law Dog. Mine are losing paint on the outside and have plenty of issues on the inside or under the hood. It would still seem in that case mine are not that bad. Dont have enough rain out here to worry much about rust from that. Sun baking and roasting everything is a bigger problem here in Texas. Not had any local hood fires yet. Or the style of bon fire that includes a few houses.

    As for the clutch. I adjusted it further to be like Macro. I have yet to post pics of it though but I think 2 years ago now. The hole in the firewall got a LOT bigger. Last owner had the transmission redone and installed a pressure plate that is a little too much for the cable stopper and as such. Ripper the hole off. Tore all the way behind the brake booster. My braces there are still holding nicely so far.
