Hello, new member here. We bought our EX-L new and have kept up with all maintenance, and the vehicle now has about 115K miles on it. Over the years, we have noticed a bit of oil consumption between oil changes but never more than a quart until two months ago in early July. While turning into my neighborhood one day, the van suddenly lost power (I've heard it called limp mode) and the check engine light came on. While waiting for the tow truck, I decided to check the oil and it did not register on the dip stick at all. We were 4000 miles past the previous oil change and I admit I had not been monitoring oil level during that time. Our trustworthy independent mechanic found that the oil was 3 quarts low and that the P3400 computer code was active. After refilling the oil, the code would not clear and he said the code indicated the VTEC solenoid was stuck, timing was hampered, and the oil pressure switch was bad. We went with his recommendation to replace the pressure switch and change the oil, which then allowed the P3400 code to clear. He printed out the TSB 11-033 for me, which talks about the VCM system contributing to oil consumption. He recommended that we begin monitoring the oil level closely and that if we saw a high rate of consumption to take it to the dealership for "reprogramming" of the VCM system. The van ran fine after this service, and we began checking the oil weekly. We noted no drop in oil level whatsoever until about 2 weeks ago, so that was 6 weeks and about 800 miles with no loss of oil. Over the last 200 miles or so, however, it has lost 0.75 quart. I have called two Honda dealerships in my area and described the problem, and both have immediately said we likely need a piston ring job to the tune of $3000. When I asked, one of them did say something about it maybe needing a programming update. Both Honda places said the first step would be to come in and have a full diagnostic workup (~$100). I'm leery of this, however, since I know what code was active back in July (P3400) and it has run fine ever since the oil change although we are observing oil loss. Also, I'm not sure what motivation the dealership would have to tell me anything OTHER than the van needs an expensive ring job, or offer to take it off my hands for a low price on a trade-in. I talked to another independent mechanic who is a former Honda tech and he recommended starting by adding something called BG EPR to the oil to clear out deposits, then doing an oil change and watching for improvement in oil consumption. It's odd to me that the oil consumption seems to occur in fits and starts. Since we weren't checking, I don't know if our 3 quart oil loss back before this last oil change occured slowly over time or suddenly. Is there an inexpensive, objective way to tell for sure whether or not the piston rings need to be replaced? I'd love to hear experienced folks thoughts on our situation. Thank you in advance!
