Well, finally some good news. The truck is running good once again, and hopefully for more than a week this time. The long story short is to never, ever think you are saving any money by buying aftermarket parts. The long and the short of all my problems has been a poorly made aftermarket timing gear set. I have basically lost the last 2 months of what little free time I actually have, to save about $450 in parts cost.

After the second timing set proved to run even worse than the first, I left work early tonight with a dual channel Fluke oscilliscope and a plan to check my entire harness or change out the tone ring. I tore out the entire wiring harness for inspection first because i came across so many incidences where the harness was the issue, I just had to eliminate it. After 2 hours of not finding anything, I bit the bullet and yanked the valve cover and very carefully swapped the cam sprocket with the tone ring for the OEM one off my spare motor.

With the OEM tone ring in place, timing verified, and a brand new OEM cam sensor, it fires right up and runs perfectly smooth. I took it for a short drive and it is all there with no stumble or hesitation and no more P1391 code.

I snapped some pics of the oem tone ring against the aftermarket and its no wonder it didn't run right. I wanted to swap them sooner but it would run right some of the time which indicated that it could have been something else. Hindsight is 20/20 though and I am so full of would have, should have thoughts right now I likely won't sleep at all tonight for beating myself up.

I have always said that as long as I learn something at the end of the day, it was not a waste, but this little endeavor has tested my ability to grin and bear it more than anything i have ever been involved with. Partly due to the fact that I have always made good money and never had to sacrifice before, especially on things that matter like a daily driver. I was trying to cut corners to make my accountant (my wife) happy and it bit me in the ass hard. Let this be a lesson to all of you. Some things you just can't cheat. The stress this has caused in my personal life has been far more expensive than the parts ever would have been but I have learned a very valuable lesson that will not be forgotten any time soon.

Here are pics of the first tone wheel compared to an OEM one. OEM on the left, Cheapo on the right.





Here's a couple more of the two cheapo tone wheels. The first on the left, the warranty replacement on the right...The replacement was even poorer quality than the first.

Glad it's working! Don't lose any more sleep, we all do it(some times much worse than this). I once left a sock in the TB of my buell then put the air cleaner and airbox cover back on and fired it up......that was costly...

Ouch, that had to hurt. At least my decision only cost me some time and didn't cause further damage.

I contacted the company that sold me the timing set to let them know that they have a serious quality control issue and they were very thankful. In addition to have already sent me a second kit free of charge, the issued me a full refund within minutes of receiving my email.

Not bad customer support but I find it hard to believe that they were unaware of quality issues. After all, they are selling their kit for a fraction of what others kits cost.

Now I have to make the decision whether I want to continue running the other pieces of the kit or swap them all out. Do I have to go OEM or would Cloyes be just as good? I am very fearful of aftermarket at this point but i also know there is a huge gap between aftermarket companies and some actually do meet or exceed oem.

Decisions, decisions. The truck is running like a champ so far so I dont have to do anything right away at least.

That's usually the big clue.

I ALWAYS run aftermarket parts in all my vehicles and have only had one part that gave me an issue (slave cylinder for my s10 from advanced discount auto parts....don't remember the brand). Big names with good reputation like Cloyes will be fine. I recently bought some Gates parts for my wife's car (timing belt, water pump, etc...). Goodyear betls, etc... even Duralast from autozone isn't bad. I'd stick with aftermarket but stay away from unknown brands and super cheap brands. I try to buy "the best" aftermarket parts, always research them a little bit to find other people that use them with success or failure, and I have only had that one problem (I didn't research it at all...).

I stopped in at my local O'Reilly's and had them order the Cloyes Cam Sprocket so I can check out the quality before I buy. I found a spot where I can buy a complete Cloyes set for $385 shipped so with my refund, it will only cost me another $225 to upgrade to the Cloyes set.

Guess what I am doing this weekend? :biggrin:

That's right, I am yanking my engine again due to a failed head gasket or cracked head, not too sure yet. I have been slowly losing coolant due to a cracked reservoir jug and was keeping close tabs on it but something changed recently and it dropped a lot of fluid between my checks and overheated on my way to work monday. Now it has coolant in a cylinder and is coming close to hydrolocking on startup so it's gotta come apart.

I had already planned to replace the timing set and leaking seals so the bulk of the work was going to be done anyways, so it's not that much bigger a deal or cost to yank it and go thru it all again. Considering what I want to do, I think it will all go so much easier out of the truck. My wife will be very pleased if I can stop all the oil from leaking on the driveway as well. Nothing like a new engine leaking all over the driveway.

I'm having a hard time mustering the energy to start the project this morning but I rented a car for the next 2 weeks so I'm taking my time and using better parts.

I have heard that the third times the charm, lol.

Nice!Hey consider going with the remanufactured crate motor. I put one in mine and it came with a 3 year 100,000 mile warranty. Love it!

I'm glad that worked out for you. I have had one go bad for me in the past and the warranty was next to impossible to cash in so I have no interest in going that route again.

I got the engine out and torn down and it's not as bad as i thought. Turns out my coolant loss is more due to cheap head gaskets than the cracked coolant reservoir. It appears that I have coolant residue in 5 out of 8 cylinders.

I have the heads off now and will be dropping them off first thing monday morning to be inspected and decked. Warpage was minimal but there was still signs of coolant passing between cylinders so I am ordering a set of OEM Head gaskets as well as a few other OEM parts for the reassembly.

Everything else looks good so it looks like I caught it in time. I am taking my time and using good parts so hopefully this is the last time I ever have to go into this thing.

My beast is up and running again smoother than ever. I took this opportunity to fix my head gaskets and a few other outstanding issues left over from all the issues I had with the cheap timing setup.

My original heads had issues so I had to get my spare set rebuilt. I actually dodged a bullet here with the head gaskets because the cam failure I was headed towards would have been far more expensive had it been the first to fail.

Assembly went well and this time I used a Cloyes Timing set and all MOPAR gaskets and seals purchased from Mopar Online Parts at fantastic prices.
http://www.partswebsite.com/moparonlineparts/

Even after the first rebuild, I had way too much engine noise so this time I replaced a noisy idler pulley and the entire timing cover assembly due to gouges in the water pump surfaces. The previous owner must have suffered a water pump failure that deeply scarred the pump surfaces causing cavitation.

Today's plan is to replace all 4 brake rotors and pads and to pressure wash all the oil stains from my driveway.
