Top end noise when cold
My 86 f250 / I-300 makes A LOT of top end noise when started cold (only for a few seconds..) then it quiets right down and is it's normal self. It has about 160k miles on it (hard working miles) but it still runs good on the road. Any ideas on what might be the cause??

This could be caused by the oil draining back out of the filter. What brand of oil filter do you generally use?
Too heavy oil can also cause this, as thicker oil takes a little longer to reach the fartherest points in the system, which would be the lifters/valvetrain. What type/weight oil do you normally use?

My 1979 F150 have fram oil filter and oil pressure was 20 psi and it was warm outside.
Well I decide change to motorcraft oil filter with castroal 10W 30 oil now oil psi was 35.
Well fram oil filter I remove it have broke plastic bypass.
There are many people say fram is best. We try told them it worse one but they keep say my truck have 200,000 miles still run good. But when it reach 250,000 engine broke cam and lifter. It have no oil on it.

I have this same symptom on my engine. When I start it up, there is a LOT of clatter, to the point where I can actually feel it coming through the truck/seat/me, and then once the oil pressure builds it's whisper quiet.
With mine, this started up after I changed out the lifters because all 12 of them were completely sunk and collapsed. Once the new ones were in, the engine was so much quieter, but I had this when starting up.
Case in point, this is a direct pointer at what is making the noise, which is the lifters. (No clatter on start up with dead lifters / clatter with new, working lifters.) A better oil filter and maybe an oil stabilizer will keep the oil in your lifters for the next time you start it. Then they won't be dry and clacking until they fill up with oil on startup. I know what you mean though, it's quite a bit of noise.

If it's making THAT much noise and you believe it might be a filter, why would you wait until the next oil change????
Invest $5.00 and at LEAST put a different filter on that engine!! You'll "invest" a heck of a lot more if it decides to give up on you.
