Sandblast intake?

[Harmon]

I went ahead and took intake off...front and rear seal were bad, plus looks like oil was coming up the middle two bolds on intake on passenger side.

Now that its off i want to clean it up...can I sandblast it?

[gildardo01]

i dont think there would be a problem if you sand blast it... i´ll come out nice after your done... re paint it and your good to go....

Precautions need to be taken:  All the sticky, coked oil/carbon accumulations trapped in passageways (e.g., EGR passages, exhaust crossover, between the heat shield and manifold casting, etc.) need to be removed to prevent abrasives from lodging in the goo and later releasing into a running engine.  Milled gasket surfaces should be taped off.  And, the manifold should be thoroughly cleaned afterward to remove all traces of hidden abrasives.  You might consider having it hot tanked.

Maybe paint stripper would work

i´ve thrown them into a fire and let the oil and all that burn, they come out looking really clean... just have to brush the carbon that´s usually left over sometimes.. and their ready for paint... i dont think people on here will think it´s a good idea, but it works for me..... i only do this on steel or cast iron definitely not on aluminum and if their hot i never cool them down by pouring water on them, might make the metal brittle... i just let them cool by themselves....

Heating should be done carefully and to the correct temperatures so I would advise against it. Your best bet is to chemically strip it. If the funds are available look into an upgrade. Regarding those end seals, use RTV instead. You will find severl threads here with pointers on replacing or resealing the intake manifold.

i would never heat a head or and engine block or things that are risky to replace, an intake when i tried iti didn´t hava a problem.... but who ever does it has to use their own judgment.. i got the idea from a video on youtube that there was this machine shop that would heat the blocks and burn all the oil and stuff off of them so i tried it will an alternator bracket first and it worked, them i tried it on the rest of the brackets... until one day i tried it on a ford 390 intake and it worked great, thats  about all i´ve done... and aluminum intakes aren´t that expensive, might consider a Summit intake, cheaper that an Edelbrock if your worried about the price, they go for less than 150 dollars...

My summit intake is great. Just use the edelbrock intake gaskets.

Castrol Supper Clean, or equivilant, then Aircraft paint stripper.
