Removing gasket residue
Toyota pickup timing cover to water pump, cover surface. Most of old gasket peeled right away, but there are few small stubborn areas. Aluminum cover. I remembered some gasket remover I bought 10-15 years ago that worked great. It just loosened up the old gasket (probably started to dissolve it). I don't remember the brand, but it might have been Permatex. So I went over to NAPA and they had one Permatex. Foaming liquid comes out through a small brush. Clearly not the same type stuff. You're supposed to apply it and wait 15 minutes before scraping off with a plastic scraper or wipe off with a rag. Doesn't work.
I remember the old stuff contained methylene chloride - like paint stripper. THis Califonia, so I'm sure that anything that is effective is banned now. tried alittle PB Blaster on a rag, and it seems to work a little bit better. I hate to use a razor scraper on aluminum, but I might be forced into that. Anybody have a good method of dealing with baked on gasket on aluminum?
I really don't want it to leak after I get done with this. I just replaced the radiator and hoses, and that fixed most of my coolant leak, but there was still some coming off the bottom of the pump.
Thanks in advance, Jim
