Here are a few pics of the last set i milled from a 2004 dr that i bought As you can see in the pics one of the ports on the end is flat and the other end of one manifold has an 1/8 gap showing light and the other had a 3/16 gap View attachment 191584 view attachment 191583 view. Broken or warped manifolds aren't a new problem,lol My dad used to braze up fe ford manifolds alot back in the 60's/70's as they were famous for cracking on 352 and 390 fords. I’m sure if i guy went through the old threads enough i could find the answer to this but the threads seem voluminous
Cast iron exhaust manifolds have always been subject to warping as long as i can remember I got an exhaust tic from one in my first car, a 64 sport fury in the late 60s Exhaust manifolds have always warped Compare the gusset thickness of the newer manifolds to those of the sixties and you'll see why problems with exhaust manifolds, especially broken bolts, were fairly rare. According to the service records, the replaced the front rotors and pads just before i bought the vehicle When applying the brakes i feel a pulsation through the pedal.which to me feels like a warped rotor.
Just noticed my shield was off passenger manifold, yup 2 broken on that side from what i can see Drivers side is still see them all in place and shield tight but who knows You guys replacing the heat shields also My 2016 has 47k miles My driver side shield was tight on all 4 corners until i. Also it's never been in heat over 95 deg.
Anyone else experienced this or have a reason why. I assumed that this was the infamous hemi tick and honestly didn't give it much thought Having a warped head or blown head gasket shouldn't cause a blockage like this Pull the water pump and make sure the inlet and outlet aren't blocked, and that the impeller is ok Most of the water pumps these days have plastic impellers that can easily break apart.
