I have 6 Dodge Rams 1500 dating all the way back to a 1997 Ram 1500 a 2001 Ram 1500 a 2004 Ram 1500 a 2011 Ram 1500 and now it 2012 Ram 1500. Tried to change the valve lifters my self and found a loose rocker arm. I would swap the plug and coil on 8 cylinder with those in cylinder 1. I was advised to replace with non mds lifters and to use a tuner to delete the mds I'm using superchips unfortunately 15,000 miles later I drive a a lot it seems to be having the same issue. This is an absolutely horrible experience.
Since the mesh cannot be precisely measured for mass properties, inertia, etc. Gave it the truck back to me drove fine smooth as silk Hemi horsepower strong as ever. Im just trying to see what my options are. New crate motor has also failed see 3 and 8 on list of failures E. I am no longer a Dodge Ram hemi fan ready to change over to Chevy Silverado.
Good point though as the lifters are the deactivation mode on these, not like the old Cadillac V8-6-4 where the rocker arms were moved. Reason I questioned the mechanical wear on a lobe is that since the 1980s and later, manufacturers use roller hydraulic lifters. Seemed a little sluggish starting up hills but they told me that it was normal and the truck goes into 4 cylinder mode sometimes. Simultaneously, a baseline virtual valvetrain simulation model is built and validated. The mesh used was one of the first ones created. Arrington has just revamped its line of high performance camshafts. I drove it about 15 miles and it came back on and the truck shakes like crazy around 1800 rpms.
Or is it just a guess???? Clear diagnostic code and run engine. Bad lifters and cam, driver's side. When the lobe designs are complete, they are sent to be manufactured in our state of the art manufacturing facility. Did you ask for the detailed diagnostic procedure the mechanic used to pinpoint a worn camshaft lobe? I took my truck in for a simple exhaust manifold leak and left with a camshaft problem. I won't be buying a Dodge product ever again. For fun I checked Kelly Blue Book.
Im just trying to see what my options are. Probably done that way to simplify the system. I replaced the cam, retimed it, and ran it anorher 100k miles before my dad sold it to someone, and they drove it 50k miles before they totaled it. Same issue as so many others. Not wasting my time mentioning all the other common problems that I had before, like exhaust manifold bolts, win module etc. I cannot stress enough that to stay away from these engines, even in the Charger and Challenger. The next morning get in the truck to go to work starts misfiring again.
I realize it's only one data point, but my '06 Ram 1500 Hemi has over 257K miles and is running fine. Truck started hesitating and developed a shake during acceleration. I tend to think lifter vice cam lobe itself, but it is pretty easy to verify with the removal of the valve cover and dial indicator check the lift of the rockers with rotation of the engine to compare the lift of the rockers to another cylinder next to it. After the prototype cam is manufactured, it's sent to the dyno for the real testing to begin. For fun I checked Kelly Blue Book. When used with Comp Cams beehive valve springs and increased ratio Pro Magnum rocker arms, the result is a faster valve opening and closing, while maintaining complete valve train control.
I realize it's only one data point, but my '06 Ram 1500 Hemi has over 257K miles and is running fine. How many miles can you realistically expect to get out of these engines? I took it to a dealer, and they assured me it was mechanical. I know the hemi has a good reputation, i just figured maybe if i fix this, should i be able to get another 100k? If ignition wiring is functional with no issues then it is possible there is a problem with the lifter assembly itself. A fuel delivery issue on injector 8 or a spark issue on cylinder 8 can also cause a misfire. My question is, is this one of the cylinder deactivation cylinders that could have failed? This should be a recall, Ram or Chrysler or Fiat or whatever the heck they're called now.
The roller lifter reduced camshaft wear dramatically such that it would be very unusual to see lobes worn out. Now this process is being applied to our Mopar street and race engines. He rercommends replacing camshaft, lifters, valve job, timing chain, gears. I searched the reviews for the shop and saying that he was very trustworthy. Dunno, maybe if i knew more about the longevity of the hemi in general, i might be able to make a better decision.
It's been a pleasure using Moes performance Was this review helpful to you? Clear diagnostic code and run engine. Then January 2019, 6 months later truck started running rough idle very rough Lee and would not accelerate. What he said fell in line with what the dealer told me unfortunately. Clear diagnostic code and run engine. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
The block is a 1988 service block, and I was of the opinion that the entire engine had been a service replacement. I know the hemi has a good reputation, i just figured maybe if i fix this, should i be able to get another 100k? Expectedly, the larger displacement 6. He also informed me that it's possible that the camshaft have been eat up and that he could fix the broken bolts on the manifold he had to bore new thread holds on the heads on both sides. If there is anybody that has any suggestion on how to get this problem more out in the open, let me know. Virtual Prototyping was utilized to provide a cost effective alternative to physical testing. Or is it just a guess???? I replaced the cam, retimed it, and ran it anorher 100k miles before my dad sold it to someone, and they drove it 50k miles before they totaled it. Does the misfire code move to 1 cylinder.
