I've never done an intake gasket before. Of course, advice on how to best clean and prep is ALL OVER the place. Scotch Brite. No Scotch Brite. Roloc wheel, NO, not that, plastic scraper only and solvents, NO, use a razor blade and solvents, acetone, NO, use brake cleaner, NO not brake cleaner, use ___ . I tried a more gentle method last night with a razor blade - actually, with a new exacto blade because it's wider than a razor blade and just as sharp. And using plastic (blue) scotch-brite (basically a kitchen sponge with a non-scratch scrubber on the back) and some brake cleaner. Sadly, there is some pitting/corrosion on the intake where it mates with the rear coolant ports which aren't used. They're blocked off there so coolant pools and corrosives crystallize there and cling to the intake material. I think a new gasket will seal. The Edelbrock install guide says use Gaskachinch (which I interpret as a product like Permatex High Tack dressing/sealer) to hold the gasket in place and encourage good sealing. SO I think I'll do that. Any other tips/tricks? I'll suck out the valley and ports real good and add some more protective layering while cleaning to catch debris. This is definitely a backyard job, good enough. I don't have enough interest or zeal to go have stuff hot-dipped, machined, etc. It was sealed before, so it should seal again. Right?! -

I have one station in my area back to Prewar E-85 pricing. $2.199. Everyone one else and every other grade still 86 cents to a buck higher. This chart is Shell V Power Nitro Plus 93 at my cheapest source and with my 4% COSTCO discount card. Dating back to 9/11/2024 -

Local Weather tells us that we tied a record in June for hottest single day on record since the 1930 "Dust Bowl" period. We also set a record for number of consecutive days of 100F or more F heat index for June. July is going to start with a three day string of 100+ heat index days. We may get some relief on Saturday but even that day is a Level 1 risk. I can't imagine what it is like for those east of us that are 10 degrees hotter. Whew! Saw some guys in a grocery store parking lot yesterday hand patching pot holes in mid afternoon covered head to toe in dark heavy clothing and hats. Nothing but eyeballs to be seen. Working like madmen. Not a water bottle in sight. That's nuts.
