oil (non) circulation
Hello all, I just ordered an AE diagnostic tool, when I receive it I will post the results of tests. More importantly, today I became a premium member of Powerstroke.org to support the site and in recognition that the greatest tool I have is access to the knowledge held by the members of this site. Thank You all for sharing.
I have posted infrequently here, and got some great feedback, but I have been unable to resolve the underlying issue(s) with my high mileage 02 F250. Namely; low power/stumbling until good and hot, more recently delayed/hard shifting and an oil leak somewhere in the valley. I think a major problem is slowly developing and I hope to nip it in the bud.
About two months ago I discovered a bit of oil in the degas bottle, so I replaced the seals in the oil cooler. at the same time I flushed the coolant system and changed the oil. I believe the oil must have gummed up the thermostat as it started to run cool when I noticed the oil in the coolant,and has continued to run cool, but I am dreading the R&R as I just did it about 5mos ago when the waterpump failed.
I get about 450 miles on a full tank and I add about quart of oil each time, I am surprised, and concerned with how clean and cool the oil is on the dipstick. I mean clean almost like new. the oil pressure on the dash gauge has always come up normally and the temp gauge never gets above halfway.
I´m just spitballing symptoms here and I know it may not be very useful info, but I also worry that the AE results may not provide a smoking gun. I have arranged a secure garage with a pit for teardown of the turbo pedestal and HPOP in order to find the oil leak, and I´ll use this opportunity to test compression and install EGT gauge.
I guess aside from crying ¨help¨to all you wizards, I´m looking for insight into how all these symptoms may be tied together at one root cause or should I be looking for multiple faults.
