    Pulling pan for inspection

    After a carb failure last week I've developed an engine knock. I'm assuming a lot of raw fuel was dumped into the sump diluting the oil. I had the oil changed on the weekend to be safe but apparently too late. On the way to work Monday a knock developed at 2000 RPM and by the time I arrived it...

    oil pressure sender

    Hi guys, Is there room for a stupid question here? Hope so cuz it's all I've got:) The pressure gauge on my 81 is cosistently pegged. I've looked at the archives and under the hood. Too much oily wiring to spot an orange wire in that mess. Is the oil pressure gauge sender unit a two...

    Wiring diagram

    Has anyone seen a source for nice (large) wiring diagrams for our cars. I want one for the 81. I had a alternator belt shred on the freeway the other day and the steel of the belt shorted some wires going up front. I thought they were non-critical but somewhere a headlight wire has a slight...

    81 radiators

    Amigos, In the seemingly endless quest to get this 81 back to reliable temp control in the desert. It's been perfect the last week after all of last weekends work. The new thermostat was probably the solution. Today the project was to install the new shroud to replace the shattered...

    81 parking brake?

    Hi folks, When I bought my 81 many years ago I noticed early on that there were no shoes in the parking brake assembly and the cables were Ty-rapped to the trailing arm.. I thought it odd so asked a knowledgable Corvette friend about it. His reply was "they cause a lot of trouble, leave it...

    Shark mouth panel?

    Soon to be using the 81 for a lot of hiway driving to/from a new job. With that in mind, what's the deal with the bottom panel below the rad opening? The lower jaw of a shark mouth, if you will. Does it help? Hinder? How fragile and exposed is it when installed. My 81 has never had it so I have...

    Interior fan C3/C4 upgrade

    Help!! I am so P'd off and frustrated at the moment searching for a supplier to SELL me a C4 fan and motor to upgrade my C3 interior fan. The online catalogs are a freakin' JOKE. With several of the suppliers I can't find a magic combination of words to even find the parts. Finally I found...

    81 Air diverter valve

    Has anybody got the black plastic air diverter valve that switches the air pump from the air filter to the Cat? My 81 has to pass emissions and the TURD mechanic refuses to substitute a different valve into that function. I know of lot of these emissions systems have been junked so maybe...

    I have a mirrored glass passenger side T-top for an 81 for sale. Fits other years as well. Green glass on the inside. I had to buy a mismatched set to replace my missing drivers side glass so I don't need this one. $260 with free shipping. I also have a pair of fleece lined bags supposedly for...

    Edelbrock carb for 81?

    Greetings friends, My 81 is getting ten to the gallon on a freshly rebuilt engine. I know the stock M4VE carb is messed up and I have to run with the solenoid unplugged for it to run decently. It also fails SMOG checks regularly. So a couple of questions if you will... 1. Is the distributors...

    81 power steering valve

    Greetings Amigos, I spent the last weekend replacing the steering column rag joint and the power steering control valve ball stud. As soon as I had it out I realized the ball stud was fine but I replaced it anyway. I did adjust the balance side to side to what I felt was pretty nuetral. Back...

    81 Power steering issue

    Greetings all, In another step on the road to recovery...This poor abused 81 needs so much... Can anyone explain what the link is between the steering pitman arm and the power steering control valve? Is this rebuildable or do I need a new control valve. The power steering works fine (too fine)...

    81 Emissions lines

    Greetings all, Can anyone point me to an on-line diagram of our emissions controls? My underhood sticker is missing and I've got to put in an EGR valve for the annual test. Even more importantly, I suspect the air pump is not blowing into the manifolds and I'm sure I need that dilution. Thanx...

    Exterior door handles

    Can anyone point me to the real reason our exterior door handles stick down? I've gotta slam my door repeatedly to make it latch and it seems to be worse after oiling evrything in sight. I've seen aftermarket springs to put under the push lever but that just doesn't seem right to me. Anybody...

    Babbitt shortage

    Judging from the subterranaean sounds I believe I've got a severe babbitt shortage on one of my rod bearings. Since this will be my first forayn into a V-8 are there any tricks I should know before I pull it out? I guess I'll leave the trans in and insure the torque converter stays with the...

    Tachometer out of service

    Greetings friends, I've just registered after reading all your thoughts for many, many months. My 81 has been well and truly used and abused by too many of the wrong owners. I think every single system needs some attention. "Ridden hard and put away wet" is an apt metaphor. I find myself...
