Default Engine ticking Cold start

I've got the 2.5 with 152K when the engine is cold it ticks or rattles a little bit in the top part of the motor when you start of a morning but after a min or two you don't hear it again what
could it be? It acts like it takes a little while for the oil to reach the top of the motor. Is this normal for these engine? Has great oil pressue full of oil it is due a oil change i'm thinking of using some lucas oil stabilizar. What weight oil should i use?

I would seafoam it before you change the oil. & get rid of the Fram oil filter.

Where do u live?

Does it do it when the outside temp is warm and cold or just when it is cold outside

If only when it's cold may wanna switch to a different weight oil

I live in tn. Seems to do it no matter what temp outside. It does not get louder when you race the motor up actually goes away. Didn't really seem to do it until now its time for oil change. But after a min or two no noise at all. The engine has 152k. I'm thinking gummed up push rod or maybe lifter slow pumping up. I was thinking on using Lucas stabilizar because seems to clinging for better cold starts.

Exclamation

Ok here's the up date changed the oil put a little thicker and lucased still same sound did'nt change. I was told they don't have lifters but was told the cam could be wore a little letting the rockers be loose any truth to this. You can listen with thesascopes to the valve cover under the throttlebody and theirs a rattle when you move it forwards or backwards you don't hear it. i'm just worried it could be a rodbearing, i've also listened to the oilpan you can hear it there very very faintly not any where as loud as the valve cover.

From your discription it is perfectly normal. If my assumption is right you valves have hydraulic buckets and as the tolerances wear with age this becomes more prevalent. the noise is from where the oil seeps out of the tappet buckets while not in use, then it takes a little bit for the oil to penetrate back into the tight gap. There is still oil getting to them fine, if there were not you would know in a heartbeat. Hmmm, Rod, well it would ound like someone was tapping on the block with a ball peen hammer, not even close to the sound of valve chatter. It sounds to me like you are fine. I would keep the oil in the 10w family and lucas additive is a good idea as it will help the oil cling in the bucket. The thicker the oil the longer it will take it to get into the tight clearance of the bucket. . .

So valve chatter is normal? My truck is at 153k and it does the same thing but it's near the bottom of the engine. When I rev it it goes away and normally once it's fully warmed up.
