I have used KBS Coatings on many projects and it works. I did a set of wheels on my utility trailer that sits outdoors 5 years ago and they are still rust free. They ship by mail too.
I would be more inclined to suspect a bent rocker arm from the original incident that allowed the push rod to get off kilter and be damaged. It would be hard to imagine spring bind on a stock valvetrain with stock replacement springs.
I thought injectors are 0-5v square wave? Pull your chip out of the computer and check it for bent pins. Reinsert the chip and see how it runs, of course disconnect the computer power wire first. Sometimes this fixes oddities. Your codes are about the MAF readings.
Valve springs are easy, need the rocker arm tool, valve springs and a handful of extra keepers in case one or two go flying. Comp Cam 980-12 springs unless someone knows better.
Use cork valve cover gaskets, not sure about rear main as I never did mine.
Not sure you need a turbo, the chip and...
R&E Paint Supply used to be a good source to buy paint online and will ship smaller quantities. I did my own fillers at home - the originals finally dry rotted and fell apart. I bought a can of black base coat and a can of 2K urethane clear. I prepped them first, sanding and priming until I...
Muffler shops put those little L brackets on all the time for the rubber hangers. Maybe its a good time to wire it in place and take it there? For probably $50 they can do something custom and save alot of headache in a few minutes.
60# injectors and E85 does not sound good to me. Since E85 needs 30% more volume that makes your injectors effectively 42s. Sounds like time to step way up.
No sir. It's a one foot long connector, smooth enough inside that I see no issue. The pro cars always do better with no restrictions of any kind, turbos hanging out the hood or through the grille with an inlet bell. With a MAF and an aircleaner, there is going to be a restriction of some kind...
