Intake manifold

Theres a swooshing sound coming from my intake so I decided to tear it all apart and check the hoses. Looks like a got a few that are cracked or just getting old so Im going to replace those.

 

Since I have the intake out whats the best way of cleaning intake manifold? I tried TBC and it didnt even do anything. Its that black crusty carbon monoxide buildup.

 

I was curious to what another piece is on that intake just above the egr control solenoid valve(pic below) so I took it off and found out that it is almost plugged up with that black crusty stuff inside. The size of the hole was reduced to about pencil size because of that buildup and its about 3/16 supposedly.I was able to clean it out by scraping it with a flathead screwdriver and a dremel.

Just did little greys a couple weekends ago.

 

To clean grease and dirt and mild carbon deposits, my favorite is Marine Clean from Por-15. Kicks serious A and quite economical when purchased by the gallon.

 

But to remove the thick black crusty carbon deposits inside the EGR passages, the fastest approach is a brass (or stiff nylon) bristle brush. Once all loose is gone, use spray on carb cleaner or Marine Clean to remove last film and expose aluminum.

Thanks Martin :beer: That POR-15 is some serious stuff yet very safe to use

 

MARINE CLEAN™ is a complex mixture of organic & inorganic

chemicals. It is non-toxic, biodegradable, water-based, and has

no noxious odors nor chlorinated solvents. It doesn't contain any

petroleum products and has no fl ash point. Marine Clean represents

a revolutionary breakthrough in cleaners, degreasers and

dispersants.

 

 

Im going to head to general store see if they have this stuff :cool2:

Good luck! I order mine direct from POR as I couldn't find it anywhere locally. The Castrol purple stuff is pretty good as well - kinda like Simple Green on steroids. If you do find the Marine Clean, or if you use the purple, wear gloves. Both are very effective grease cutters - effective enough that it will leach the fat out of your skin leaving it a bit worse for wear.

Buy a gallon and dilute per their instructions. At 5 to 1 with hot water, it cleaned my intake and heads right up! Spray, let soak a few minutes, rinse. Repeat if necessary. A little brushing for thick crusty areas.

 

I keep several spray bottles at various ratios on the shelf.

Ordered the 1 gallon. Ive been using crud cutter for years but this one seems like it would work better.
