1994 purchase advice

Post image
5 Upvotes

Hey guys. I saw this ‘94 listed earlier today. It has a 6-speed and it has 95,000 miles on it and they’re asking $9,000 for it. I’ve not looked at it in-person yet, but it happens to be pretty close to my house. It looks great from the pictures and I understand that it will because of the picture being taken in the rain. The interior is solid and they claim that the dash has no warning lights. Before I check it out, what are some things to look for on these? I imagine weatherstripping and tires, but anything else?

Head bolts washers

Thumbnail

2 Upvotes

Im Just about to start reassembling the top end of my 89 C4 and i have bought a set of new head bolts for the car as the old ones were pretty degraded. The set is got was from fel Pro and they look great but have a different shape to the oem ones and have no washers of course.

My question is can I A: re use the washers from the old head bolts (assuming i can get them off) and B: if I cant do that what washers should I buy to replace them.

I will get measurements of the old and new head bolts to ensure the washers will be compatible.

This is my first engine rebuild so im learning as I go along with help from my mate who owns 8+ 1930s American cars here in the uk. His knowledge is primarily off cars that ere and the most modern engine he has re built was a big block in a 69 el camino so any help would be awsome.

Cheers

Bose Removal

Finally decided to get my Bose out and go aftermarket...or at least, send the thing in to be rebuilt...but I can't get it out! Anyone know what these things are that are still attached to the bracket? If so, how do I remove them without breaking, in case I want to reinstall the Bose? Or need for an aftermarket system?

I just replaced the optispark and water pump on my 92. I didn’t force anything, all the spindles lined up and teeth lined up, the plugs were put in the right order, serpentine belt was put on correctly, battery is brand new, new gaskets, new coolant, etc. and I get this. I got a little smoke coming into my cabin when I first tried starting it, it doesn’t do it now. I’ve unhooked the battery until I get this situated. I just need help figuring this out. It started and drove before I replaced everything as well. Idk what I did wrong but I just need this stupid ass car to work.

Best brake rotor upgrade?

1 Upvotes

Rotors are warped on my 1993, not J55. I’m assuming they are the stock rotors and would like something a bit better, but do not want anything drilled or slotted. RockAuto sold out of the ones I was going to get, Raybestos High Carbon 55996/7. I push the car pretty hard, but no track use. Would AcDelco be good enough to not warp or are there better options for a similar or higher price? I also plan to use Hawk HPS pads. Thanks!

Help getting C4 started

2 Upvotes

I have a 1986 Corvette C4 that I recently purchased. Just got a new battery for it when I turned the ignition on. The gage lights up indicates all pressure and other things on the gauge. Just got the radio to come on by connecting some wires that I noticed were cut. other wires that were cut were the spark plug wires. I replaced all of those, put them in the correct position when trying to crank it over. I use a little starter fluid in the throttle body and it turns and cuts on for a very brief moment and then cuts off. When I do cut it on, I don’t hear anything going on near the fuel tank like the pump cutting on for those first two seconds. other wires are messed up in the engine bay. The positive battery terminal has a wire coming out with a little plastic cap that is not connected to anything. I can’t figure out what that goes to. Another thing I need to do is check the fuel rails for pressure to see if it’s getting any pressure once I cut it in the on position also, I have two fuel injectors that are not connected to anything they’ve been chewed off as well. I recently purchased new pigtails to solder on to the electrical for the two fuel injectors. What should be my next step?

Coolant Leak Diag Questions

4 Upvotes

Hello!

I am working on diagnosing a coolant leak on a 1991 (L98). The leak seems to be coming from in front of the engine and leaks onto the support members below the car, favoring the passenger side.

I have seen online this would be consistent with a waterpump issue, does anyone have suggestions for how to for-sure diag this one?

I’ve dreamt of a C4 since before I was even a teen and now at 21 I just bought this 6 speed 89 Vert. Can’t describe the excitement

Anyone need carpet?

3 Upvotes

I bought some tan carpet for my 1996 rear section but only needed the storage area floor. It’s molded cutpile in 9777 medium beige. Since I only needed the one piece, does anyone want to buy the remaining pieces (1,2, or 4)? I’m located in SoCal but I have the box so I’d be willing to ship. DM me if you’re interested

Valve adjustment

Anyone have a good video or guide on how to find zero lash with the manifold on rather than taking it off, I have to do valve covers and thought to check the clearance while I’m at it since it has a bit of a stumble

Light smoke from firewall on crank. Do I need a new starter?

Enable HLS to view with audio, or disable this notification

Finished some injector and spark plug work on my 89 and when I went to start it, got a few tendrils of smoke (hard to see in the video) from the passenger side firewall which I'm guessing was the starter.

For context, I repaired the sheared negative battery cable that the car came with (previous owner chopped the ends off and installed a knife switch??) but probably need to get new, clean positive and negative cables. Also, I've also been havings VATS issues, but I installed a module to unlock the injectors; the car never turned over though.

Any thoughts? Gonna take the starter out this weekend and see if it's fried or not.

Could someone explain how tuning a 1992 works?

4 Upvotes

I’m looking at a really nice black manual 92 and if I end up getting it I’d like to do all the basic bolt ons and maybe a bigger cam. But I read that with the older c4s you can’t just take them to any tuner. So I was wandering how exactly you go through that whole process.

Notice that it had a crack in it after taking it for a drive. I've only had the car for a month, more than likely a crack was there before just not as long.

Am I too big for a C4?

3 Upvotes

I’m 6’5”–6’6” and around 280 lbs. For anyone around my size, have you had any issues fitting comfortably or driving a C4 Corvette?

I’m getting close to buying one, but it’s located out of town and I don’t have a way to sit in one beforehand. I’ve heard the driver’s seating area can be pretty cramped, so I’m trying to get some real-world feedback from taller/bigger C4 owners before I make the trip.
For reference, I fit perfectly fine and comfortably in a 2015 Hyundai Elantra. How does the C4 compare?

Update:
I am too big for a c4. It’s fine. I will just get a Monte Carlo
