2011 Optimax Pro XS - In service date Jan/2012
Engine# IB861903
287 hours
First let me say that I'm a big fan of Don and what he does. Not just at his shop, but especially for all of us here on BBC. Even buy all my parts from him and Rhonda.
That said, I have a problem that I need addressed, and waiting 3 months is a hard pill to swallow.
My Opti has decided it needs fuel rail servicing. Wife noticed it was rough starting a couple months ago, but by the time I got the truck/trailer parked and down to the dock it had settled out.
However, it ended up being down on power after a few trips this year so I pulled the plugs and noticed #4 was looking fouled, so I figured it was the coil. *Last year it was #5 and a coil for sure, so figured that was the problem with the dark #4 plug this time out.* NOT so lucky this time. Replaced the plugs, (and coil) then pinned out the old coil and it all seems to be in spec.
Took a trip to the lake to check running condition and it's still sluggish out of the hole, and down on top end RPM. Don't have a dual-liquid gauge here so took it to a local shop to at least check air and fuel pressures.
Air in the fuel, fuel in the air. GREAT... that means tracker valve, and possibly both the air and fuel pressure diaphragm(s). Tracker valve replaced last year, less than 30 hours. Total hours are 287. Checked reeds with a borescope when doing the plugs, they look great. Still down on power though and a rough idle.
With the diagnosis of air/fuel mixing, it's clear that #4 isn't fouling, it's LEAN. Noticeable higher temp on #4 just running on muffs. Running at the lake from this point isn't going to happen! We were supposed to be at The Chick next week for a week. NOT!!!!!
That said, as much as I'd prefer to go to Don to have the service, after speaking with him this week and confirming 75~90 days wait I just don't think we can put this out till middle of January.
(I understand he's had some health issues this year, me too. Getting an emergency MRI Tuesday for L5. Already had 2 surgeries there. Probably end up with rods this time. IF I end up having back surgery #5, then it's a sign from the Good Lord to go ahead and send the rails to Don.)
That said....
I could *REALLY* use some input on other shops that are doing quality work on Opti fuel rails & injectors.
Don't want to step on any toes, but I'm in a tough spot here. Perhaps PM's with recommendations would work?????
Thanks guys!
