Rocks in a can? Aliens? Edit: Water Pump was bad!!
it's the end of the world- or at least it sounds like it!!!!!
'96 4.0, AW4, 184,500 miles.
Watch the video and listen to the racket. You should be able to pick up a slight tick tick tick of the exhaust leak from the manifold- I am replacing it with an APN header this weekend.
What concerns me though, is the 'rocks in a can' LOUD rattle I hear. It happens as soon as the engine is started, keeps pace with rpm's.
I hastily pulled off the flexplate cover Saturday thinking for sure I'd find a loose bolt- they were all tight. I didn't see any cracks in the plate, but I wasn't looking for any, either- I was sure I'd find loose bolt(s). When I didn't, I thought it must be the exhaust leak making the sound. -But it has gotten louder and worse over the last few days. I poked around with a stethoscope, and the sound seems to be coming from (or at least is loudest thru the scope) the right side of the oil pan, where the pump is.
This was a completely stock Jeep until the last couple of months when I got it back form the in-laws after them having it for 10 years. So far I've rebuilt the rear brakes, changed rear axle lube, new leafs/bushings/u-bolts and shocks in the rear.
Magnaflow cat and Dynomax cat-back put on 2 weeks ago. Engine is Stock with the exception of the awesome Spectre cone filter and breather you'll see in the video. Changed the oil with Rotella 15-40 a couple weeks ago planning on dropping the pan this weekend to do rear main seal as well.
Last week changed the tranny and transfer case fluid. Both were nasty. Flushed and filled the coolant, new T-stat Saturday also.
So- tranny and transfer case fluids changed, new T-stat and coolant flush was done Saturday, which is when the rattling sound took off-
coincidence?
I'm trying to upload the video now...
