Russ - Glad to hear it's a popular product among those in your business (and our hobby). Hopefully I'll have good luck with it. It's probably a good thing there isn't a Harbor Freight outlet anywhere near me. I'd be broke from filling my pick-up bed with tools every chance I got.
Unfortunately, things aren't going well with the rust removal. I failed to notice an unplugged oil gallery hole in the side of the block - I believe it's part of the optional filtering system - and some of the Evapo-Rust
may have gotten into the block. Since this stuff is non-toxic, non-corrosive, etc. I wasn't all that worried about it, but I still wanted to clean out the oil gallery anyway. In the process of removing the pipe plugs (I had the machinist tap the oil gallery holes for threaded plugs when I had the engine rebuilt), I stripped the head of the plug at the rear of the block. It's only partially removed, barely a thread or two from flush, so it's going to be a trick to remove and replace. The machinist had put something on the threads, possibly to keep the plugs in place. I may have to heat that area of the block to see if I can remove the plug. Or... is that not advised? I don't really know of any other way to remove the plug. There isn't enough of the plug sticking out to grab onto it with Vice Grips. I'd rather not drill it and use an easy out, as that will introduce metal shavings to the inside of the engine. Thoughts??
It's rather frustrating when the hobbies we choose for stress relief and a release from the grind end up causing a headache. At this point, I'm finding myself very tempted to:
1. Disassemble the engine.
2. Remove aforementioned plug by whatever means necessary.
3. Finish the rust removal with a bare block.
4. Go ahead and modify the oil passages for full-flow filtering like I had planned to in the first place.
5. Reassemble the engine.
6. Paint the engine.
What do you guys think? Does that make sense? Or am I overreacting? I really wanted to do the oil gallery modification, but the machinist had my engine work done before I got with him on the plans for the full-flow filtering modifications. The modifications seem simple enough, I've read several articles on the work. I guess my question is: Does it seem like a waste to tear this thing down, perform more work to it, then reassemble everything? I suppose it's as inefficient as it could be, but to me, it seems like I'll get a better end result. Maybe not?
Thanks for your thoughts, sorry to vent so much.
Damon
PS. On a positive note, the Evapo-Rust seems to be doing the trick on getting rid of the corrosion on the outside of the block... I forgot to mention that.
