[Shotimes] Strange noise...help!

[Ian Fisher]

Yeah but then you are ignoring the flickering oil light problem..When I
replaced my front motor mount (one of the times at least) I disconnected
my lower rad house for more room. After bolting it back together, I put
the hose and place and poured more coolant into the system. I ran it for
a bit; oil psi light was flickering like crazy at idle and I was getting
some lower end clatter. I posted to this list as well as Techsho and
some people suggested that overheating the motor from the lack of
coolant will cause bearing problems since the oil is getting cooked and
losing its viscosity. I forget the specifics but it made sense at the
time. I bought a set of rod bearings and plastigauge with the idea of
replacing the bearings just in case, but I never did it. Sold them to a
friend and ended up recently getting a whole 'nother set of rod/main
bearings for my bedroom 3.2.

Well, the noise comes from all over, plus you can hear it in the car.
Much like any noise, it always sounds like it's coming from the top of
the motor until you check it out more closely.

Not sure that a motor getting hot will give you a rod noise from
clearances getting too tight, the bad-bearing noise is when they are too
loose. Detonation/pinging can be from being too hot. Maybe a cavitating
water pump from trying to pump air?

Rod bearing noise has often been reported as resonating as if the noise
was coming from the top of the motor. My theory; when the t-stat and
water pump were replaced, the coolant wasn't properly refilled and the
t-stat might be stuck (air in the system). The motor is overheating
after running after a few minutes and the bearing clearances are getting
tight. It happened to me, but I decided to add coolant to the rad
instead of the overflow (duh) and start it up and take it for a cool
down drive when I felt it was safe to do so. No more bearing noise
since.

Well, my bearings were TOAST at 86K:

But, mine's also a 5-speed. Ian mentioned the bearings, but I dunno
about that, as bearings start making noise right off the bat, not after
5-10 minutes of driving.

Oil light flicker could also be from a slightly-too-low idle. Off the
top of my head, could the "new" water pump be acting up? Maybe after
getting hot, the blades are hitting the housing. I wouldn't suspect
anything in the top of the engine, as the clearances close up when it
gets hot.

Without the noise, I would suggest it is the oil pressure sensor. I
would change that 1st anyhow. 67K miles is low for a rod knock. Mine
didn't start until 165K or so and only under certain situations.
