Hi,
I have a 1985 Merc 260 that spikes it's oil pressure at 80 PSI immediately after start up.
This engine also has an intermittent lifter tick that I assume is related. My guess is this lifter ticking and the 80 PSI is due to an oil passage blockage somewhere.
Fresh oil (10-30) and filter, nothing changed. I was hoping the blockage was in the oil filter.
I have not yet changed out the oil pressure sending unit but I guess that's my next step to make sure the 80PSI is not a bad reading.
Has anyone encountered this issue before?
