I drilled my spotwelds out over 20 years ago. It makes it so easy to remove the doghouse to pull the engine or even to clean and paint the engine and surrounding parts. I reattached it by using short sheetmetal screws.
What did you use to seal between the Doghouse and floor?
Since the seats connect to the Doghouse you should secure it really well to the floor again. You may also have to move the wire harness if it still passes through the wall of the doghouse, and anything else connected to the doghouse wall.
I am working on that right now, only diffents is mine will bolt down. I also am interested in what type of gasket to use. Another thing to remember is if it removable you may need to move something that attach to the doghouse.
I really think some type of rubber gasket is the way to go. (for me anyway)The idea of cleaning off old silicone and reapplying everytime just would add time I don't have.
Yeah, that would be better if you plan on removing it often. I just don't see me doing it other than for a powerplant remove or install. But man, it would really be nice for that!!
mine wasnt a complete removal/ bolt-in but here are a few pics that might help... http://vintagevans.forumup.jobs/viewtopic.php?t=8836&mforum=vintagevans the flange from the donor D/H was rusted (and i needed to shorten the height to match the original one) so i made a sheetmetal flange and drilled holes and bolted it in. i have some flat rubber to seal it but i wanted to paint it first , which i havent done yet, so point is, with no sealant and just bolted in, i dont notice any heat or odor slippin in. good luck, james
Yeah, thats kinda what i'm thinking. Weld some bolts all the way around from underneath and secure the doghouse down that way. For the best access. Rather than weld it down permanent like.
It has always been my understanding that silicon and mettle are a bad mix. A while back I had posted a response to silicone around a windshield...it had eaten almost the entire mettle lip that holds the gasket to the frame. Hit the brakes real hard one time and the windshield took off. Now I don't no about engine gasket silicone, if this is different stuff, but tub and tile is what my Dad always used and everything he had that on rusted out. Somebody set me straight on this or am I wrong on house hold silicone on vans and trucks
When your run of the mill silicone cures it releases an acetic acid (sp)? I have made the mistake in the past using it for sealing conduit on an enclosed electrical panel, it creates corrosion something fierce. If RTV is different Im not sure.
