82 dodge 150 4 spd slant six(225) 1 barrel unk. mileage
About a month ago my truck started giving me a ticking sound at startup.It was getting close to
o/c time.I had been running Valvoline MaxLife Semi Synthetic 5w30 w/ a baldwin filter and a pint of MMO.
So i decided to go ahead with an o/c.10w30 synthetic blend max again with a microguard filter and a pint of wynn's friction proofing.The tick went away for a week and then came back.it seems to be back around the 5-6 cylinder area.I added a pint of MMO.The tick went away for a week or so and then came back with a knock in the same area that goes away when the engine warms up good.The knock went away.Came back.Repeat at random intervals.lol.
The day after the o/c the oil was very dark,almost a charcoal color.With some apparent particulates in the oil.Several days after that oil returned to its usual brownish color.
So my question is ...has my use of MMO caused a piece of buildup to break loose and float around occassionally blocking an oil passage?I hesitate to say sludge as this engine is not known for that ,but it is 27 yrs old.I'm thinking of changing the filter in another week or so and adding another pint of MMO.And repeat as needed.Say every 2 weeks or monthly.
My commute and casual driving is about 1900 miles every month.75 mile round trip at 60-65 mph workday commute.I should be able to do a cleaning cycle fairly quickly.
Does this seem an appropriate treatment?
