Hey guys. I'm sorry, I haven't read the entire thread. I just don't have the hours unfortunately. I've read a fair chunk of it, but I have a couple of questions.
1. Is there any way to monitor what's going on with the injector seals and oil pickup using an OBDII connector? I read on another thread about Toyota's Techstream software which appears to use a wired OBD connector. Techstream can, apparently, read oil pickup and injection feedback values. Can other software or apps do this too? I use Torque Pro on my Android devices, but it doesn't seem to include support for those values.
2. My 2010 KUN26 has 230000km on it now. I bought it at 120k. To my knowledge the injectors and seals have never been looked at. They definitely haven't since I've owned it and there's nothing in the service book to suggest they've been done before. I changed the oil on the weekend and the oil pickup mesh looks perfectly clean and shiny. No sign of any deposits. I didn't think to strain the oil, but I will next time I change it. Is it worth having the seals changed, or am I better off not screwing with it until I (hopefully never) see the carbon deposits begin to appear? I'm thinking I should at least get the valve clearances done, so I'm guessing it's worth getting the injectors checked and seals replaced at the same time? Can't you only reconnect the fuel lines twice before they need to be replaced?
3. I know it's been asked already and the advice has been to get Toyota to do it, but how hard are the seals and valve clearances to do myself? I'm pretty handy. Have changed my own clutch a few times along with countless other jobs. Timing belts, water pumps, alternators, radiators, transfer cases etc. Would love to hear from people who have done it.
4. Does anyone use an inspection camera for an Android phone to get a better look at the pickup mesh? If so I'd love suggestions on which one to buy. It would obviously need an incorporated LED light, and a close focus ability. I wonder if such a thing could be used to look for carbon blobs in the bottom of the sump too?
It really seems like the carbon blobs in the sump are the most reliable early warning sign of the injector seals failing. So being able to pick that up as early as possible seems like the key to knowing when the seals need to be changed. Every 45000km seems like it will be a very expensive exercise for someone regional like me who does those sorts of distances every 2 years. Yeah I get it's not much compared to a full engine rebuild, but while my pickup strainer is clean, I'm finding it hard to justify the cost.
cheers
