just put a new altinator,starter,cylinoid, waterpump, and thermostat. my oil pressure is at zero and its squeeking like hell could the oil pump be the problem?

 

or could it be bearing in the cam shaft or something?

 

could be a spun main bearing

 

I suspect you knocked the oil pressure wire off when changing the water pump. Also got an idea that the pump maybe making the noise.

i checked the wires when i noticed the oil pressure was gone and they were all in but im suspecting the nothing is being lubricated because its not a constant or rythmic squeek it sounds like either a bearing is messed up or something is not lubricated i will change the oil pump tomarro and we will decide from there.

 

but if need be how do you change the main bearing

 

Bub, Changing a water pump does not knock out an oil pump. You are quite callable to bang your own knuckles, but just reading your post, your issue seems to be at the top of the engine. I don't believe main bearings squeak. I urge you not to go after the oil pump, without further help.

Maybe a mouse crawled into the oil pan, is squeeking cuz it wants out!

 

Before disassembling the engine suggest looking into possible causes that are less labor intensive. From the list of items installed don't see anything that would cause the problem except perhaps the water pump or a fan belt not centered, or it's binding. Had a simular issue, thought it possible the water pump so I squirted some penetrating oil into the relief hole in the watter pump and it quieted down somewhat thus determined it had to be replaced. Can't do much diagnosing until determine the cause of no oil pressure; possiably bad sending unit;keeping in mind, there are 2 different type oil prssure sending units; if replaced, make sure the sending unit matches the type gauge. Without running the engine, pull the valve cover and turn over couple cycles to determine if oil is getting to the heads? Curious if the noise continues with the clutch disingaged. Anyhow, couple suggestions as food for thought?

 

im not saying that changing the water pump would knock out the oil pump but it did over heat not bad enough to blow the motor the thermostat had the original blue pain on the gasket from when it came out of the factury so i figure the guy i bought it from never put anything into it to keep it in any more shape than running. when i changed the oil it was nasty so i put a half quart of marvels mystery oil and i kinda suspect that it knocked some sluggy oil loose. i was hoping the noise was the the water pump because its coming from the front of the engine and i the oil pump is on the front of the engine on the 352. it was not doing this 3 days ago so realy i have no clue. i worked in a machanic shop for 2 years but i never diagnosed vehicles i just followed a list of things to do so im not obliviouse to machanic work just diagnosing them.

 

i can get another truck that has been rolled with a good engine that i was going to buy eventually for my brother because he needs the rear end so all these parts im buying will not go to waist if the motor is blown so im not worried about waisting money because i planned to buy that motor and put new everything on it eventually so any little guesses will be helpful

 

its not the clutch i already got under the truck and listented to the transmission and the clutch

 

started it up today oil pump kicked up squealing stopped and oil pressure went up but theres a nocking noise coming from the top of the motor im going to check my lifters

 

main bearings squeak when spun or dry what kind of knocking like a rattle like lifters or like iron?

 

well ive heard a piston nock before and it dont sound like one. its not to loud you can notice it from inside the truck untill you press the gas so im not so sure.
