    Puzzled- Excessive Oil in Throttle body

    Now- P0172 code? I’m still looking for my vacuum leak and now I’m randomly getting a P0172 code? P0172 indicates that there is “too much gasoline being detected in the exhaust gases exiting the combustion chamber”?? Thoughts???

    Trying to track down my vacuum leak, I have a port underneath the intake that has a cap on it. Hum….?? See pictures below. I don’t see a vacuum line on the schematic with a cap?

    Yes I agree; 5w30 seems a bit too thin for the 1fzfe. I only ran it for the first 300ish miles after the rebuild for break in, then changed the oil (Valvoline 5w30 again) for roughly another 300ish miles before I went back to Rotella 15w40. I was hoping the 15w40 would resolve my oil...

    Puzzled- Excessive Oil in Throttle body

    While pulled over to add oil, I looked over all my vacuum lines again. And I found this- see picture below. There’s a small crack where the vacuum lines go into my charcoal canister. Did I find the culprit? I don’t remember ever seeing these before. I’d assume I caused it when standing in the...

    Unfortunately, I only took the one picture of the Hastings rings box. So, I just called the machine shop and they are going to see if they can find the original invoice with a part #. In regards to the baffle, nope- I didn’t remove at all. All I did was open the two vents that seemed to be...

    Hum… I reset ECM when I did the compression test, maybe 2000-2500 miles ago. I would assume that’s long enough for the ECM to “relearn”?? With the towing, I held off on towing anything until today (roughly 3250 on rebuild) and surprisingly oil consumption doesn’t seem and different towing...

    Here is a few pics of vacuum current vacuum routing. It’s definitely RPM dependent, the faster I go, the more oil it pushes into the throttle body and intake. On the highway traveling at 75-80 mph it will use about double the oil versus this morning I drove from Durango Colorado to Montrose...

    This is Great feedback guys- I really appreciate the help! Engine assembly: machine shop did all the machine work and complete head rebuild and I assembled the block. We used Hastings Piston rings on DNJ pistons and Mahle bearings. Only one ring in my ring set had any markings, small dot (I...

    Correct- new .50 over pistons, new rings, bored and honed the block for the pistons, turned the crank, new larger crank bearing, reconditioned rods/new rod bearings. Surfaced/cleaned and inspected the block. Head was cleaned, inspected, multiple valves were replaced, a few valve buckets and all...

    Hello All, This website has been a tremendous help to me in rebuilding my 1997 LX450 but after hours of searching and no real explanation, I’m turning to you all for help. I recently rebuilt the 1Fz-Fe engine (roughly 3010 miles on rebuild) and I am having major oil consumption issues. What...
