For some time already, I can hear lifters making noise. It doesn't happen all the time. Sometimes early morning during start up, and sometimes never att all... Tonight after a long trip I was unpacking, and the noise was there. I have 15w40 Castrol Magnetic in the engine, could that be the problem, or maybe this is common in straight six ?

Same annoyance,I think its the oil filter location.
Mine is 90 2.6 oil filter is in the upright position.
Maybe overnight when the car sits for a longer period of time,the oil from the filter drains back down.
Solution? Use OEM filter.
Result? The same.But it only takes a few seconds.
Lets live w/it.

Is it possible that it s the injectors making this noise.They can be pretty loud when cold.
