I feel I've seen alot of these lately but everyone's situation seems different and their resolutions so far have not helped mine.

My 96 listed below, to the best of my knowledge all these issues have come up after I did the build, truck ran and drove without issue before hand, are these symptoms of tuning or assembly?

I installed the parts listed below, took it to my friend who has a chassis dyno and he has a friend that does tuning using HP tuners. Neither of them have experience with tuning one of these but I figured I'd give them a shot. This is my first experience with any work out side plenum gaskets on these motors.

I bought the truck about 6 months ago after it has been parked for probably 3ish years. It need some work to be road worthy hence the reason it was parked, driveline, brakes ect ect. The Truck had almost no exhaust on it either. At this time I installed the longtube headers, offroad y pipe and exhaust system. 3" through a 3" x 20" cherry bomb to a 3" x 2/2.5" outlets super10. I installed a new 02 sensor as removing the old ones seems like a waste of time, the system only allows for fitment of the upstream sensor.

I drive the truck like this quite awhile up until maybe 1.5 months ago. Where I had decided my heads I was doing for another truck needed to get installed on something before they rusted to bits on my garage floor. Its At this point I decided to installed everything I have been hoarding. I installed a New Cam (hyperlink to cam card), lifters and tubes (stock length), EQ heads ported/blended/guides cut with the recommended valve springs for the cam, .047" MLS head gaskets with ARP studs, roller timing chain, new ign coil, plugs, wires, cap, rotor, cam position sensor (Due to lots of corrosion under the cap no change with old sensor installed), the keg has VRP plates installed with the plenum plate welded on, F&B 58mm throttle body, reusing all my old sensors, the keg 2 bbl was milled out for the 58mm blades

Dizzy was synced back to 0 with a scanner, fuel pressure is 52-54psi steady, comp tested all cylinders they are 185-200psi

The truck wont behave on the dyno just free spinning the drums or under load, (worse under load) the truck will just start coughing and popping/backfiring white smoke over around 3k, there was conflicting readings from the truck 02 saying rich to the dyno tailpipe 02 saying lean, tuner installed a wide band 02 and confirmed truck was rich

it was suggested I change plugs, in this process I discovered I had installed the wrong heat range plugs, so I installed the recommended E3 plugs for this truck but the result is the same, just sitting in my yard free revving the engine it behaves the same way. If I hold the throttle steady at what should be about 4200 rpm the truck will stumble and fall and rev back up ranging in RPM 3500-4500

My main question is, is this a normal situation of installing a cam and not having the right tuning or am I fighting a bigger issue, possibly fuel injector? Possibly timed the cam wrong? Faulty new 02 sensor?

I recorded some video. I'll work on getting them uploaded to youtube and posting links in, you will notice in my videos I have my scan gauge hooked up watching readings. I'm not real familiar with a scan gauge on these trucks but the map reading appears to be sensor voltage, TPS is a percentage, IGN I assuming is a timing reading in * you'll notice it spikes up to 40* which seems ridiculous too

 

Looks like it is sucking oil from somewhere..... (blue smoke) the clouds of white at higher RPM are kinda odd though....

Check engine light is on, what codes are coming up?

 

I cant recall the numbers offhand but 02 sensor codes, p0141 and p0138 IIRC both are bank 1 sensor 2 i believe, assuming the downstream sensor that isn't present, at one point i had a cylinder 4 misfire but that has not returned

I just cant figure where the oil is coming in at, its not in the intake, damaged guide or stem seal? At 180+ i cant believe its past the rings, I saw no areas of concern on the cylinder walls, I have driven the trck a fair amount and have not seen a drop in oil level

 

Might be running a bit rich..... but, I would expect the smoke to be grey, or more toward black, than blue... How many miles on it since you put it back together?

 

Very few as I didn't want to drive it much until I got tuning. maybe 50?

I just temporarily solved the issue though, I was trying to figure out a pattern and why it cleans up over 5k rpm it, ran smooth just smoked some. I was testing with the intake off and the vacuum lines disconnected and capped. Didn't even pay attention to the temp gauge creeping over, I bet I no longer have 185+ on all cylinders, just hope I didn't ruin my heads, trying to keep it running and get it cooled down. Definitely not my smartest moment but live and learn, guess a built motor is coming my way now though

 

If you have the cooling system empty, the first start up, I expect to see the gauge go pretty high before the thermostat actually opens.... One of the reasons I like to drill a small hole in it, or get one with the jiggler valve.... lets that air escape, and the thermostat actually works the way it is supposed to.

 

thermostat has definitely opened before, I've driven it some and we had it on the dyno for 1-2hoursdoing pulls, never noticed an overheating issue but apparently holding high rpms for a few minutes did. Defnitley feeling 0 for 2 on electric fans, my Cummins doesn't get along with em either, might be going back to stock fans on both

 

With electric fans, you need to make sure they have adequate flow rate. For a truck, I don't think one is enough.....

 

Well my diesel has the the Flex a lite kit for that truck, it does great daily driving but heck most dodge trucks dont need a fan daily driving with their enormous radiators, it struggles when towing though

This truck I have the FFD extreme cooling kit, its 2 fans

 

And it still overheats??? That doesn't seem quite right.
