98 S10 Vortec V6 4.3 Intake Gasket Replacement Part 1 of 5
Well I think I have a bad intake gasket on the drivers side. I had a small coolant leak coming from the water pump but now I have a pretty bad leak that is getting on the Exhaust manifold on the drivers side. Going to take it off and have a look. From what I have seen online intake gaskets are a pretty common thing on the 4.3 and 5.7 vortec engines. I will try to be as detailed as I can to help others doing this same job.

GM 4.3L V6 / 5.7L V8 - Fuel Spider Swap, SCPI to MPFI
Video of me swapping the fuel spider out of my vortec after it failed. All the tools and tricks needed for the job are outlined in the video. 5/8'' Crows foot will be your best friend. here were the symptoms: Truck would start rough and require throttle to even out when warm. Would usually cold start fine. This lasted for about 6 months, then it got to where it would be so flooded it would run like shit and not even out. fuel pressure regulator was dumping fuel out of itself and into the upper intake; whenever the fuel pump turned off. I demonstrated this in the video with the plenum off and the injectors plugged in. please subscribe to help keep my channel growing If your have a pre-2003 4.3L I highly recommend you replace your poppets with the new multi port spider. Just about the best upgrade you could do. Changed the plugs and wires as well and now get 19mpg (up from 16 with the poppets). this video was a nightmare to edit (filmed back in august) and the audio from the camera doesn't sound right royalty free music tecknoaxe i think is how you spell his name......





How To Perform a Compression Test - EricTheCarGuy
Compression Testing and What You Can Learn From It - EricTheCarGuy Here is a video on performing a compression test on an engine to assess it's mechanical condition. An engines ability to compress air and fuel is directly proportional to it's performance since an engine is nothing more than an air compressor once you take away all the controls. A compression test is a good general test that will give you an idea of the engine's overall health but it does not give specific information on what the problem is should there be one, for that a "leak down test" would be required, here is a link to that video. http://www.youtube.com/watch?v=WgrfT0LFMhc However if you find yourself looking for the source of a performance problem with an engine, this is a great place to start. This test is often overlooked in favor of looking at the fuel or ignition system, I think that's a mistake, if an engine can't perform mechanically no amount of electronics will make that better.
