    99 / 4.3 - What was a drop or two has now turned into a puddle. Oil pressure is fine until I lose a lot of oil which I have been checking daily since problem started. Pressure washed under carriage and now see oil running down the oil filter. Not sure if I use UV dye I'll be able to see where...

    UPDATE** It’s not getting fuel * SES still doesn’t come on with key on. I’m assuming the bulb burnt out so I move onto crank no start. I have spark so I poured a little fuel in the throttle body and it fired right up then died. So I’m onto no fuel. I have a 1990 S10 Blazer 4.3 4x4 with some...

    1992 S10 Blazer 4x4, TBI 4.3L Engine cranks. I have spark. Engine acts like it wants to start, almost starts to run, and just immediately dies once key releases. I've tested fuel pump relay, ignition coil, pick up coil, control module, etc, etc. And everything else I could think of to look up...

    Hi all, I just completed putting my 1989 4.3 V6 262 TBI motor back together. It is running really bad, and sounds like random misfires. It keeps running rich and fouling the plugs. It sounds like it has a radical cam but it does not. It’s acting like plug wires are crossed, but I have checked...

    Alright so I’m pretty sure this truck is cursed. But long story short it’s been sitting about 8-10 years with intermittent periods of driving the last two years. I finally had time and money and have been getting it up to become my daily. Two weeks ago I had the fuel pump and tank replaced. Fuel...

    Hello i need some help. I just put new spark plugs and new wires on my truck. It's a 2003 sonoma with the 4.3. It starts up but it's very rough at idle and the check engine light came on and instead of me thinking its a misfire, it's a p0118(engine coolant tempature sensor circuit high voltage...

    My 97 Jimmy is gonna need an engine overhaul soon and I'd like to put a cam in it, I've been looking at the Magnum Computer Controlled 206/210 Hydraulic Roller Cam Chevrolet 262/4.3L V6 from Comp Cams but I just want to know what else I would need for it to work. I want a cam for a bit more...

    Hi, so my 91 S10 4.3 blew up. Injector stuck open and dumped over a gallon of gas into my oil pan going 60 on the highway. Engines toast. Crank destroyed and the rod bearings spun so bad it toasted the rods. I picked up a free low mileage 1985 4.3 from an el Camino. I plan to swap intakes and...

    Hi all, This is my first post here and in all honesty I'm pretty green when it comes to just about everything mechanical (so go easy on me please.) However, I figured joining a forum like this with a lot of knowledgable individuals would be a good place to gain some knowledge of my own...

    Im trying to put one of these on an aftermarket filter, is it supposed to buzz? Would I have to adapt the hot air intake snorkel from the stock air cleaner for it to stop buzzing? Also just to be sure, is this thing for vacuum pressure orr temp?

    Replaced original air cleaner with edelbrock 14". Im just wondering how important is the diaphragm on the stock air cleaner? It was hooked up to the 's' on my tbi. The edelbrock air cleaner didnt have any temp sensor or anything so rn the air cleaner is not connected to anything else with hoses...

    I have a 1996 ZR2 (4.3) and an ongoing issue that it has is overheating at idle. This happens in hot weather as well as cooler weather. As soon as I start moving (doesn't have to be highway speeds) the temp drops back down. Less than a year ago I flushed out the coolant system and put new...
