Sound coming from engine

[Route--66--]

Cool
weirdly enough I just changed my diff oil last weekend .. and fuel pump with filter the weekend before! ..we must be on the same schedule!

I'm about 20 miles north of Birmingham, so that's about 115miles north of Reading.

Let us know how you get on with the noise ... if it is the same as we had, the wd40/pb will stop the noise.. at least until the lube wears off..

here's a pic of my belt after changing for a longer one ..

(I actually got one a tiny bit too long and had to change it again .. doh..)

All the best

Some folks use a string to measure the "exact" length for a belt, there's a spray on "belt dressing" for the noise (it just wears off like the WD40 (that's really seen as just a cleaner round here).

If your hearing is still good, You can also do it the old redneck way using a length of brome handle for water pumps, alternators etc. it's a bit safer too.

And that is why I emphasized it should be a long rod (or screwdriver)

I stand by what I said.

I always opt for the safest tool for the job. A long metal rod contacting any moving surface could get puhed right through an ear. Ever stumble, sneeze or get starteled. It only takes once at the wrong time.

Have to say I always used a trolley jack handle
.. but have now got a mechanics stethoscope .. think it was just a fiver off ebay..bargain!

My Dad always used the screwdriver. He's still alive. Granted the '69 torino does have a shroud around the fan... Mine is LONG GONE. I've got two little kids to fret about, so maybe I'll find some other way of isolating the noise.

The noise in question is gone, but I get the feeling the engine doesn't sound right. I don't know if I'm being paranoid at this point or not. I started hearing a noise from the engine in my '97 F150 about a year after I bought it new (first new vehicle). I got the runaraound from the local stealership and unloaded it shortly after. Dealership thought I was nuts. I felt very vindicated when I found out later the early 4.6l was prone to piston slap. I just don't have enough run time with this engine yet to know what is 'normal' and what isn't.

Do not put your ear directly on the water pump while the engine is running. That would be bad.

ah, you sound much like me with these things!
I have piston slap in mine for a few minutes until it warms up to operating temperature, spoke to a few peopke about this who say don't take much notice unless it starts to burn oil. mine burns no oil at all and the only thing that it does is makes a bit of noise to start with

it sounds almost exactly like this http://www.youtube.com/watch?v=geDRmNKH0Pg
even to the point that for a few seconds after starting it makes no noise at all.
The sound in this video sounds actually louder than i get on mine but the actual noise is the sane..

I dunno. I'm needing a new haircut.... It would be a lot easier than getting the lawn mower out. :mrgreen:

LOL, my truck was never that bad. I just started hearing a metal rubbing sound that wasn't there before. I didn't want to wait to find out.

Car got inspected today (yay).

Drove the car tonight. Sound is back. And more persistent this time. Hopefully I can get my head under the hood this weekend, isolate it, and put together a plan to fix.

But hey, the car passed inspection. :mrgreen:

Nice one
Do try the WD40 between the inside of the belt and water pump pulley trick - would be really interested to know

 

[65fback]

I didn't solve this last fall. Tried the wd40 trick last week. It worked for a short time. Also put on a longer alternator belt. Sound isn't coming from the alternator. I used the screwdriver trick and didn't hear anything. I'm going to go ahead and replace the water pump. Does anyone have advise on a good supplier for them?

 

[woodbutcher]

All good suggestions,and safety first.
Route66.Another use for WD40 that I have found is this.When you are done tinkering with your car,spray your hands with it and then "scrub"them together real good.It will loosen the grime really well.Then use a good quality liquid dish soap to finish the job.Rinse well with the hottest water that you can tolerate.I use Dawn(R) dish washing liquid myself.
Good luck.Have fun.Be safe.

Cool, if spraying wd40 on the inside of the belt solves the noise, even if for a short time, you don't need a new water pump.. I fitted a new one and it made no difference - it was just a noise coming from the fanbelt in the end .. yeh my noise wasn't coming from the alternator. maybe your pulleys (and mine) are a tiny bit out of line ..

Interesting comment about wd40 as hand cleaner - will have a go at that next time cheers!

 

[65fback]

I have good news and bad news.

Looks like we were both wrong 66. It wasn't the bearings (me) or the fanbelt (you).

It was the....

impeller (http://s1049.photobucket.com/user/65fba ... 6.jpg.html) on the pump having self imploded last year from all the crap just before I flushed the coolant. I should have done it FIRST. Silly me expecting the guy I bought it from who had 'put it back together' to have actually gone through the fluids.

One piece of the impeller was wedged into the opening in the block. The rest are.... somewhere in the coolant system.

Am I looking at doing a disassembly of the engine far sooner than I thought?

 

[chad]

Boy, there R alot of different opinions on this one.
The main thing is to flush & observe as doing so. Wanna look 2 C if there is a good steady flow of water (the water jacket is clear) as fluid goes in (and observe the out). I would "flush in both directions" with the radiator pulled out of the "water loop". (more differing opinions) I'd have the radiator cleaned (bolied professionally). And shove a hose in the 'water neck' of the motor watching the lower hose till clean. Drain everything first so as to not pollute the local ground water. THen you can just leave the system open as the water flowing through will B - just water. Observe about 10 min of steady flush onto the ground.

 

[Route--66--]

WOW!.. I did not see that one coming !!
I guess it's hard to diagnose noise on a forum without video sound, but even so I'm surprised at that one !
So what on earth would have caused that - assume there must have been some play in the bearings for the blades to have been knocked off as I guess they are made from a non ferrous metal so shouldn't have rusted.

Yeh, as per what Chad says with the flushing .. I flushed and back flushed my system when I changed the water / anti-freeze.

All the best !!

 

[65fback]

When I said there was some nasty stuff flushing out of the coolant system last summer after the heater core let go I mean there was some NASTY STUFF. There was some *SOLID* nasty stuff behind the thermostat. It was just.... NASTY STUFF. The bearing doesn't have that much wiggle room. No, I think some of that stuff made its way to the impeller and did its job. I guess we'll never know.

And I did post a video with the beginnings of the sound last year. But it definitely has evolved since then.

As for boiling the radiator, it's seen better days. I think when they swapped engines out they didn't pull the radiator when they first tried, if you get my drift.

 

[chad]

Do U think you'll hafta go one better? and keep the system closed - run a flush product in there to clean? Now it's sounding more like a real gummed up thing.
If it's really bad some pull & dissemble the motor...
Again, look in the water neck & if it's caroded, the diameter is reduced in size (w/crud) it's in more trouble than I thought...
