Squealing coming from Engine Bay

[seapuppy]

andrew...thanks for posting.....my memory of the system is one hose should go to the carb intake that is doing all the sucking...this causes a neg. pressure on the crankcase....the other hose should go to the flame arrestor....just to put oil back into the system to be burned off....I seriously doubt you did any damage.....

At first I thought this was exactly what mine is/was doing, but is coming from the engine and or pullys I think. It has a squeel that i can't find. I checked the belt, changed the tension pully and had the alternator rebuilt. It still has a sqeeking noise coming from something when it is running. It is more noticeable at idle and seems, at this point to not be affecting the performance in any way, ie no overheating or loss of power etc. Whats left, the waterpump? crank?

the thoght is if it's from the front of the engine...it's got to be either the idler pully....alt. ....or....the belt...nothing else can make a squeeling noise...water pumps just start leaking.....pwr steering pump...maybe....replace the belt....betcha that's it..

It has to be a bearing or something. The power steering could be the problem. It works goodthough. The water pump has to have a bearing inside as well for the pulley to spin. It's not the belt slipping and I even tried belt dressing and more/less tension on the belt... to no avail. It literally sounds like a squeaky wheel and it squeaks a little louder in certain parts of the rotation if that makes sense. it definetly is coming from the front of the motor somewhere.

Seapuppy- My main concern was that both hoses were sucking out of the crankcase into the Carb/Manifold, and the godawful noise that was caused by this was air leaking in somewhere, or a dry bearing caused by air leaking past it. I have noticed I have used a bit of Drive Oil over the past few outings, had to top up this week, and this level had previously never moved.

Only thing that eases my mind is that the noise stopped as soon as I unhooked 1 of the hoses, so most likely was air being sucked in somewhere.

Mine sounded like it was a bearing gone. I had originally thought mine started after I filled the engine bay with water one day, I thought maybe Gimbal Bearing. However this event just happened to coincide with when I changed the Carb, and T'd the 2 rocker hoses together and to the Carb.

Not hard to check this, just check where the hoses from Rocker covers are going, if both to the manifold and carb, try unhooking 1 hose while running, noise should stop if that is the cause. Really should only be a problem if you had been playing around with things, like I had! Or its developed and air leak somewhere where it wasnt present before.

Good luck
