OK so here it is, About 400 miles ago I changed the head gasket, changed the oil and filter, changed the thermostat and flushed and filled the radiator ( Also added some barrs leak. Had a leak. It stoped ) . All seemed ok .

Then monday I jump in the truck drive to work and the engine sounds like it has no oil. So I shut her down jump out and take a look. I'm about 1/2 quart low, I thot ehh no big deal seeing as how I have a rear main seal leak I thot that's where it went, So I added alittle oil and went to work. Got there put a piece of cardboard under the truck just to make sure it was the rear main seal and no place else. Well there was no leak's at work. Drive home toss the cardboard back under the truck and did not drive it again till this morning. Same thing no oil on the cardboard at all, but ping tick clunking noise is getting out of hand. ( The rear main seal is not even leaking any more )

So I just got out of work and drove home still no sign of oil loss, and half way home ( 2.6 mile one way drive ) the sound of death went away.

The truck is not overheating and seems to run just fine. My oil pressure gauge always reads right about the A in normal . Even if the truck is shut off over night it's always on the letter A . Shouldn't the needle go to the low area when I shut the truck off ?

Someone please help .... This truck is killing me

It's now Thursday and it's getting loader. Parking the truck till I can get something figured out, Can't afford to blow the engine up .......................

 

yes it should... did you keep an eye on your gauges when you heard the sound?

 

Update, I changed the oil sending unit and now my gauge works and shows within the normal range. Everything seems fine untill the truck warms up for a few min's then it starts screaming as if it has no oil.

I have been walking to work now for a few days and it's really getting old. Does anyone have any clue what may be wrong ?

I have been thinking of changing the oil again and adding engine restore. Would this be a good idea ?

Please, Any and all idea's would be helpful.

Also when I was changing the sending unit the oil that leaked out was black as dirt, but when checking it on the dipstick it still looks clean and fresh..

 

The gauge did not move at all before changing the sending unit. I have been afraid to drive it sence changing it, Should I take it around the block a few times and see if it jumps around when it starts making the sound? Or what should I watch for ? I did look at the temp gauge when it was acting up and it showed I was running cool.

 

Ya... that's not good... if its clean on top and black on bottom... it probably means something more serious happened in the engine. Look into that.
