Long story short, I've been losing oil since I bought this truck used but didn't know where. It wasn't a high priority since the truck seemed to run fine and I was not seeing plumes of smoke starting it up although the exhaust smelled different. It wasn't until recently I decided to borescope the cylinders and that's when I found that my valve stems were leaking.
I am losing roughly a quart of oil every 3k miles of normal driving.
This is on the 5.7L 3UR.
276k miles.
I'm currently trying to prepare myself to tackle this job.
It was already tedious removing all the crap out of the way to do the valve cover gaskets recently and now I'm having to do it again and then doing the cam tower reseal since I'm already there.
Will be definitely using an air compressor to keep the valves in place, but my little 3 gal compressor may not cut it. I also need to to figure out which style valve spring tool will work too.
