Very detailed your information was really informative thank you . Ps don’t worry about the videos you will get better with more time spent in front of d camera
I quit doing them. I have thought about doing one more on the Duramax leaking fuel. I did get it fixed and probably need to explain what I found with a lift pump on a Duramax
Great job definitely a hard find went through a similar situation myself replacing distributor cap rotor plugs draw body crank sensor what a nightmare just cuz someone didn't install apart right that you thought you took off right🤦♂️
Thank You. I am fixing to retire (3/1/2024) and thinking I may take this RU-vid thing up to keep me motivated into doing something. Just making short videos trying to figure out editing.
Thanks for posting! My van I bought from a used-car dealer had zero bolts ( missing 8 of them ) on my timing chain cover. Only 2 10mm screws from the oil pan were holding the cover in place.
I have replaced the engine, transmission, and everything else. Alternator, AC compressor, condenser, radiator, power steering pump, distributor, and many other things. Van peeling paint was stripped completely and sprayed with Raptor bed liner. That was a hard job. Fixing to rebuild steering gear box, it works good just leaks.
Thanks and great video. My brother has similar van and is having similar issues and also has an injector code on the scanner. Also was reading that these 5.7 vortecs had spider injectors upgraded by the factory and it was a recall or parts bulletin upgrade deal. Also the van looks really good all white!!! Ours is Green and white with graphics in different greens on sides. Again great info
Yes, I stripped the van of the all the flaking factory paints and sprayed it with Raptor Liner bed liner. I will not do two colors of bed liner on the same vehicle again. That black and white made it more difficult.
I just spent 4 days putting new distributor in my 96 Silverado w 305 5 speed, It was a nice one owner truck 5 yrs ago. Like everything else; some items should be replaced with original A/C Delco . Just my opinion seeing how it runs so much better now.
I have spent several thousand dollars chasing what appears to be a miss fire just after every shift. Other than that it runs good so I didn't think it was a injection problem.
tengo una expres parecida a la tuya en mexico y tiene desde diciembre del año pasdado que no la puden echar a encender es un vortex 5.7 expres 1998. la semana que viene la voy a recoger y buscar otro mecanico que sepan y no solo de aprendices.. gracias me gusto la explicacion sobre el paquete de inyecores. saludos desde ags. tengo 12 1ños con esta ven son magnificas aunque gastonas pero
Not a dead misfire just ran bad. I drove it a week or so with it wrong. Well, I actually bought the van running not so good and thought I'd change the injectors. It ran the same. I took that upper intake off a few times before I figured this number issue. Now I have driven the van about 39,000 mile and it runs great.
@@DACoutBack Nice thanks for the reply. If an injector isn’t firing at all and the plug in that cylinder is still clean like new would that cause a missfire and blow air out of the exhaust? Since it isn’t igniting and is just pushing air out the exhaust? I believe my injector for #3 isn’t working. I have spark but no sign of fuel in the cylinder or plug. Exhaust is blowing and sucking air.
@@freshbutplain1144 I use a tech2 scan tool to watch my data. I was getting random misfires everywhere with the improper installation. With the injectors being inside the intake, I'm not sure how to check if the injector is firing or not? I guess I'd have to investigate on what prong is power and which ones are to fire what injector and bench test it with a battery.
@@OSHA_Violator1 I ran a fuel pump pressure test. It was below specifications. Replacing the fuel pump fixed my issue, turns out the previous owner put in a "cheap" pump.
Those intake gaskets on these vortecs are a terrible. Number 5 had dropped a bit and was sucking oil into the cylinder causing a misfire and burning oil. Poor design, gaskets are only held in place by intake bolts at the front and rear of the intake.
Wow. You just taught me something. My 2002 gmc 3500 savana 5.7 has weird misfire issues. 200k gentle miles. Random oil usage. But no smoke that I ever see. I own my own heavy equipment and truck business and I do lots of repairs myself. I check oil on my vehicles every day. Random coolant loss. Sometime I smell coolant and sometimes I don’t. The original owner up to 90k miles was a maintenance freak. He took the van to gm dealer and I have an aircraft style maintenance record of the van. He had the intake gasket etc replaced multiple times when in first 90k miles! He was a stickler and was anal about his vans. (Computer repair on military bases). I bet my oil and coolant loss is like you say. And my misfire may now be down to vacuum, spider injection and gasket. Hmmm. Thanks
@@technicalitems731 Anther clue is the brakes. Going down the road at a faster speed the brake pedal feels fine. At low RPM the pedal seems soft. The vacuum is being robbed from the booster at low RPM. Good metal Felpro gaskets keep from sagging. The stock head gaskets are crap too that is why you smell coolant. You will have a blown head gasket soon.
Starter grinds some on start up vibration at about 1200 rpm. Once torqued down backwards to the converter, I'd say trash that flexplate as you can see, it warped mine backwards. Pulled transmission 3 times now.
How did you remove the spider injectors? I have that exact style on my truck and I cant seem to pull them out. Did you have to remove the whole intake manifold out to push them out?
What brand of injectors did you buy? I have changed my injectors twice on my 99 Chevy suburban, and recently just took it to a mechanic shop and after 300 km my truck is doing the same thing I did before. Any information would be very much appreciated thank you so much for your video.
What I want to know is, how in the hell did it even run??😮. Must have picked up unburnt fuel out of the intake runner when it was actually on an intake stroke.
It ran ok. It passed inspections and everything. It did use more fuel. I have no idea. It was injecting on the wrong cylinders and I guess it would pool on the valve and dump in when the valve opened along with vapor from all the spraying onto a valve from all the injectors. It will run and you can drive it. It just doesn't run like it should. On the scan tool, it was showing a lot of misfires.
If you buy one like that you need to get the upper intake manifold as well because the factory one will not fit it. Learned the hard way and took the whole truck apart only to have that just a little bigger then the hole in it and not fit.
@@DACoutBackyep the new ones today don't fit. I just installed one on my 97 and it didn't fit in the upper intake manifold hole and was just a little bit to round and I went to 4 different parts stores with my factory upper intake manifold in hand tried them all and not aftermarket one fit. Then parts store had a acdelco factory one that was 798.00 tried it and it slipped right into there like a glove. I didn't go with the factory one because the price was way higher then 376 for that and 91 for the new intake manifold. I ended up just having the guy order a after market upper intake manifold and then once they got it we tried the aftermarket spider kit and it slipped right into the aftermarket upper intake manifold. So you had to go aftermarket to aftermarket now with that because like the guy said they have to make the aftermarket one slightly different so they don't get sued by acdelco. I guess acdelco just started making ones that was the port injection so maybe that's why they had to change the aftermarket ones slightly.
@@DACoutBack right was a pain because tore the whole top end off just to find out it didn't fit and had to wait a week to get that upper intake manifold.
It had issues. Still ran and drove. The biggest issue was going into overdrive and locking converter up it would clunk really bad. I thought it was the transmission. After fixing the injector scramble, everything smoothed out.
