spider injectors

[hiwaycruzer]

Hello from Chattanooga...

I'm replacing my injector spider with the upgrade and finally have the old unit sitting on my work bench. My question is, what is the best way to get the gooey, gritty carbon build up out of the injector holes without pushing all that crud into the combustion chamber?

Any tips or advice would be greatly appreciated.

take the manifold off and have a machine shop clean it. they do a fantastic job.

dont the new spiders come with new injectors?

Thanks Sunlit Comet, but as it's not leaking, I'm not replacing the lower intake manifold gaskets at this time. Will need some time to work up to that...
Any idea how critical it will be if some of the crud I described previously winds up in the combustion chamber?

Fishin757 - yes, the upgrade is a redesigned spider with new style injectors.

Just suck it out with a vacumn. Then clean it with carb cleaner. then put it all back together. Then do a seafoam treatment. (do the seafoam treatment outside, its really fun to see the neighbors freak out when the smoke comes from the car) =)

This is what i did when i replaced mine. I also just changed the gasket. it takes like 3 minutes to just replace the gasket

If you have if off anyway, might as well do the entire top end. Preventative maintanence

you could stuff clean rags down each runner and soak the holes, brush them out and vacuum if possible or blow maybe and pull out the the now dirty rag.

And when you seafoam it, make sure it's a bit breezy or you're not at home, those fumes stink and won't go anywhere soon without an air current.

When I did mine, i got a big plastic bin from Walmart. Then I was able to put the intakes in the bin and dumped in a gallon of mineral spirits. Some brushes, rags and paper towels and everything looks brand new.

Edit: although I removed both intakes when I did mine. Had the intake gaskets to do too so.
Just re read the op.
