Clacking noise from upper intake. Replaced and problem solved!!
I was driving home about a week ago on the highway and I was trying to get around this truck and hit the gas to pass him and that's when I heard the loud knocking
Hey I have a loud knocking coming from the top venter of my motor ..I'm really hoping its the intake runner ...but the knocking escalates with the rise of the engine rpm...doesn't get louder just quicker... Any ideas?
engine started running rough then the check engine lite came on the more i drove the more the engine sounded like it was pinging and the miss got worse after scanning code p1518 i will let you know when repair is complete
I have the knocking noise and I went and look at the control rods and the bushing on the back rod was off and rod disconnected.
The intake shell had crack. fixed that problem. We still have loud popping noise in engine?
seems like the little arms vibrate off. You cannot buy the arms by themselves, so you are told you need the whole runner control. GO TO A JUNKYARD AND GET THOSE TWO LITTLE ARMS>the intake runner is probably just fine. Mine was . Cost 8 dollars and and hour and a half to fix. Also you can bend them a bit to make them fit in snugger. The end clips to hold them are plastic and are 6 dollars each at the dealer.
Knocking noise in engine, changed to synthetic still noise. Problem has not been fixed yet. When to dealer explained that they did not hear the noise. So I will find someone other than the dealer that will listen to me...
my pinging noise comes and goes. does not do it when i have it in shop. dealer siliconed shell back together. will not do anything until they hear it.
Hose broken due to wear. Went to dealership, bought replacement hose. Installed new hose in same order.

Filled radiator with coolant. Ran engine at idle till thermostat opened. Filled coolant again to recommended level. Engine operated at normal temp for approximately thirty minutes. Stop, cut vehicle off. Hard start on restart.

Check fulid level again. All shows normal. Drove vehicle approximately 1 mile; vehicle temp runs hot. Shut down vehicle. upon inspection discovered intake hose had disconnected replaced hose (hose clicked on intake nipple).

Replace fluid, tried to restart engine. Loud knocking noise.
Engine noise when starting. Noise stops after reaching 45 - 50 mph
Running hot new water pump
