Hi Y'all i got me a 94 Toyota truck with a 22re in it,
i have already pulled the engine for the rebuild now i am on the process of tearing it down.
I am working on the intake manifold, and the inside is NASTY i mean it is really bad... and i want to clean it all up. Both the part that bolts to the head and the other part (the one that says "EFI" on it. not sure what they are really called)
Anyway does any one have any ideas on how to thoroughly Clean these?
I would really like to do this myself for as little as possible but worst case scenario i will take it to a shop that can do it... But i really am scraping the bottom of the barrel for cash (as i am sure y'all understand)
also i do not have a parts washer.

 

Get a 33 gal tote or something of similar size that can hold 4-6 gallons of water.
Get some industrial strength engine cleaner type stuff thats safe for aluminum. I bought some off-brand from Home Depot because it was the only aluminum safe cleaner they had. And it was cheap. Add the highest strength ratio, in my case it was 4 cups per gallon of water. Mix it in the large container. Let the INTAKE MANIFOLDs sit for a day or 2 in the water/cleaner. I used Scotch brite pads and a sponge with a rough top attached onto a handle. Worked really well. The inside of mine were disgusting. When i put the engine back together, they were as clean as new. Takes a lot of elbow grease, though.

 

time wise a shop can clean it faster and after u clean it it wil look the same in about 5k miles it gets that way due to the pcv valve.

 

easyest way btw to keep that from happening again is to change the pcv valve every so offten. but u will never beable to keep it from happening but u can try to regulate how bad it gets to watch how much build up u get with the new engine just pull the intake tube and open the butterfly and shine a flash light at the back of the intake or just pull the hose and see if its wet with oil

 

I used dishwasher detergent and let it sit in the sink overnight. If you live with someone, get a big plastic tub/tote instead. On the 6-cyl, I needed a bottle brush, you may need one too.
