I saw a couple of different things which looked somewhat similar to oxalic acid but mostly they didn't say what chemicals they contained so I was hesitant to use them. Bar Keeper's Friend did show on the search as well but I had similar hesitations.

 

so you asked for it in the paint department at a big hardware store and they said they did not have it . . it is powdered wood bleach.

even walmart has it.

I know, my internet search found this also at Walmart.

Unfortunately, trying to find it in the store is a whole different story. I spent about 30-min going up and down every aisle in the automotive/home improvement/paint section. Same thing with lowes and HD. I also found it on the Sherman-Williams website but when I went there the guy had no idea what I was talking about. When I would ask someone all I ever got was "what are you trying to do?"

EDIT: I just ordered it from Amazon. Hopefully it will be here by next weekend.

 

ahhh, ok thats typical . . you could have gotten liquid wood bleach which all hardware stores should have then diluted it a bit.

Since I was having trouble finding the oxalic, yesterday I bought another bottle of Blue Devil flush and started another flush with that (before I ordered the oxalic on Amazon this morning). I just ran the car for a bit, idling in the garage for about 20min, then did a 30min drive down the freeway at 60-70mph most of the way. Overall the temp gauge looked good but when I got home I had to park in the driveway and go around front to get inside and open the garage.

When I tried to start the car again I had some trouble starting. It was turning over but not catching. I had to give it quite a bit of gas to get it to catch. Normally, when the engine is warm, it starts right up so this was a little disconcerting. When it did start, the temp gauge was way higher than when I stopped just 3 minutes before. The gauge went down fairly quickly though (took maybe 30 seconds to get back to where it was before I turned it off). Is this just a gauge thing?

 

yes the gauge will go higher right after it is turned off . . the fact it quickly went down is encouraging also.

no idea what blue devil is.

did the engine turn over more slowly when it was hot?


also dont remember if you posted you timing info.

 

It's just some flush I bought at Oreily's.
It seemed to be turning over normally, just not catching.
I bought a timing light but haven't had a chance to actually use it yet.
