[@notj5712]

Ah......Opticrap. Had one of those on my 96 Impala. Very familiar. A hint for when working with those. Whatever you do, don't replace any plug wires, or plugs and for sure don't check firing order.

[@Iexpedite1]

Not J The only thing worse than the opti you took out is the one you just put in. You can’t trust an opti that isn’t equipped with a Mitsubishi opti sensor. All others are garbage that will fail in short order. Even high priced units from MSD are suspect. Mitsubishi stopped making sensors years ago. There is a guy on EBay called the opti doctor that rebuilds opti's with Mitsubishi sensors. They are pricey but you can trust them to last more than 6 months. Also while you were in there a water pump swap is a smart move. When the pump goes it often takes the opti with it. Coolant is the death of many opti sparks. Later opti's are vented which extends their life. You can, and should retrofit older opti’s with a vent.

LT1. Designed by Lotus

[@TrakSpock1]

I have over 400,000 miles on my LT1. One of the most durable engines ever made. The Optispark is also very durable and is wrongly blamed for bad spark plug wires and electrical grounds.

[@510Exclusive]

@@TrakSpock1 Good brand new AC Delco optisparks work good. But you can't find those easily anymore. They're all reman and will go out in a couple months unless you go MSD which are $500. At least thats my experience with them. Something that relies on literally looking through a hole in a metal plate to know when to send spark is not that great of a design to me. Good luck to you and your unicorn LT1.

Just let Kyle and Vince take over the bonus channel! Primo content my friends

[@greenplague5286]

Have you checked to see if the spark plugs wires are connected properly from the distributor to plug? It was done by another person so they might have mixed the wires up.

[@goman5523]

Green Plague they have done plugs so they checked that and the just did the distributor

[@greenplague5286]

@@goman5523 no they just marked the ones that were already on there instead of checking a diagram to see if the wires are going to the right plugs. That's what happend on an episode of roadkill with the engine in the back of a truck. The wires were going to the wrong plugs

[@fkncarl9302]

@@greenplague5286 The optispark is labeled with cylinder numbers. You would hope they looked to make sure it was right but the miss would be worse if it was routed wrong.

[@jumpinjimmyg2164]

Those early obd1 lt1s will kick your ass, I have a 93 6speed, rebuilt with a hotcam, the opti spark plugs/wires/coil/icm should all just be replaced right away then you can put it behind you and will most likely fix the miss. You can also get modernized Bosch 3 injectors for it for cheap. All the parts can be had for so cheap just replace it all till the miss or problem goes away. Fuel pressure regulators can leak, make sure your intake gaskets and vacuum lines aren't leaking. Replace the 02 sensors too. All the parts I mentioned if aftermarket total less than 400 bucks for all new stuff. Rock auto is a c4 owner's friend.

[@blackman9148]

Can Kyle and Vince just have their own show? This is too good and it has it all. The mustache the golden locks the love for vans the suspenders the calm demeanor. I could watch hours of this.

[@bradbozarth1822]

Came for the corvette stayed for the mustache 👌

[@keithlane4343]

Wish I caught you before you put it back together. The pre 1995 Optisparks were not vented and had some issues. The '95, and '96 Corvette Optisparks were very reliable. The one thing you should do with all of them, if you pull off the water pump, tap the bleed hole in the bottom of the water pump casting, install a simple brass fitting with a piece of vacuum tube on it and direct it away from the Opti-Spark so if the diaphram on the water pump blows out, it won't spray coolant all over your Opti and short it out. You should hang on to that Opti you removed. It's probably still good, and you know it's already been replaced at least once. I bet if you put some wires and plugs on that LT-1 it'll run like a champ. You guys are characters. Good videos. Take care.

The most said thing ever in c4 corvette forums “you check the optispark”.

second to that is "My corvette runs like sh!t!" - usually said by a crossfire owner

[@cmzangetsu1993]

i know this pain. i changed the opti in my 93 firebird recently. if new plug wires don't fix the the misfire check the O2s. i chased a misfire at cruising speed for months after changing wires and opti to find an O2 was bad.

[@OCALLARM]

Yeah, I fought it too. O2 sensor, ignition coil, plugged injectors eliminated the mis. When the optispark finally failed it wouldn't run.

@ChimRichaldsII depends on the motor. My LT1 uses green

[@pgtmr2713]

I don't think the orange crap was out while c4's were in production. Hardly saw any doing oil changes back 96-98. Maybe just the newest cars. Green stuff shouldn't hurt anything, it's not like using the wrong transmission fluid or oil.

[@lukec.8941]

@@pgtmr2713 yup. Im pretty sure if you flush your. coolant. system you can pick orange or green without. issue

That ‘Orange’ is dexcool and it should not be used in this LT1. IIRC puting the orange in a system that was always green is a no-no.

[@haraldzurnieden1920]

So what you guys have is an LT1, which is a 92-95/96, and the opti runs directly off the camshaft. Unfortunately the opti you guys put in isn't known for reliability (it's chinesium) but it should get you going, just for God's sake put on new plug wires... Before you blow another $3-500 on optis you should look at the 24x LT1 conversions for running LS coils. The '86 in your yard has an L98, which is just an EFI Gen 1 sbc. I'm really digging the videos on the C4, make sure you bring it by the burnyard bash in July if you can, I'll bring mine.

[@pmp1337]

I think this episode beats Scotto's bolt episode in pointlessness.

[@coolkidscarclub]

[@joserios3913]

Camshaft lobes perhaps!?? Since it seemed that someone previously tried repairing the misfire by putting a new distributor thing!! And in addition to the work you guys have put in!

[@PaceWorks]

We need a beer with Vince 🤣 he was either home schooled or he doesn't have television or the internet 🤣

[@mpmagnussen]

"Omg I'm so surprised the optispark is giving you headaches" said no opti owner ever

[@danielreigada1542]

When the optispark went out in mine, the car just stopped running. No misfire or anything else to give a warning. The design flaw has it right under the water pump. If the water pump leaks it can wreck the opti. The optispark is only in the 1992 to 1996 LT1 Vettes. I believe that they improved its design on the '95 and '96 models.

[@itsameyaboi]

I'm so hyped, these two should have their own show consistently

[@joeteasdale3378]

Really digging these episodes.

[@Jodeyjoe559]

heat isnt removed from cab, air is either taken from outside (usually under windshield cowl) or recirculated within the cab which is also considered max A/C. heat is removed at condenser to change refrigerant state from high pressure gas to high pressure liquid and at evaporator core to change refrigerant state from low pressure liquid to low pressure gas, thats only place A/C system is removing heat. In the cab the blower motor blows air through a freezing cold evaporator always, when heater is on it blows through evaporator still to dry the air Then through the heater core but there is always cold (dried) air being blown in inside temperature is just adjusted with the temperature blend door within the case. on max A/C the car is recirculating air INSIDE the cab not taking any air out or removing heat just cooling cold inside air

[@edmusick7794]

It's the opti spark, it's always the opti spark on the LT1 motor.

[@tylerslayton6070]

To remove and install the crank bolts, use a spanner wrench in holes around the outside of the front of the crank pulley.

[@hoost3056]

The Optispark is a known problem and there are upgraded Optispark units available. But the ultimate answer is to do an LS ignition conversion which will give more timing accuracy, and more power. Compression checking one cylinder is not enough.

You did get new wires, right?.... Also one time I had a plug that the ceramic was cracked, when you'd inspect the plug it looked good,(holding it upside down to see the electrode) BUT, when I turned it to right side up, the ceramic would slide down to the electrode, basically blocking any spark path.... Took a few days to figure out I had a junk new plug
