Hello, Im working on painting my LS1 intake and it has a thin layer of gunk or suet.

I prayed intake cleaner in, no help, power washed it, no help.

Can I put it in a parts cleaner tank and let it soak for a few days? As far as I know its Kerosene...right? Will the plastic be safe?

Please help me out, I would like it as clean as possible before I spray some primer.

Its varsol and that should cut through u t, I used it on plenty of parts with good turn out.

Are you talking about the air intake that holds the air filter? If so, I believe that kerosene will slowly dissolve it.

If you check inside the plastic piece, it should have a stamp like the ones below relating to the type of plastic that it is. From there, you can look up the chemical resistance.



ABS does not hold up to gasoline, kerosene, etc. very well. Same goes for Alcohols. (Although, I like to use dilute alcohol for cleaning really dirty trim pieces as it takes off a little bit of the surface and leave it looking like new.)

If the funk on your intake is like a water scale, etc. I'd try using CLR first.

Thanks but its the intake manifold. Im trying to clean the crap put in there from the EGR.

I just bought this car with 88k and under the hood was extremely dirty and looked like 250k. Its much cleaner now so Im going to have to sand and paint to get the bay lookin good. Figured Id start with the intake since I have a spare.

I thought I had more engine bay pics but I guess not

Scuff it up and use some wax and grease remover.

....the inside of the intake

all castings have been removed from the outside of the intake. Ready for primer but im not happy with the inside

If you are talking about carbon build-up on the inside (like what we see in the EGR) Seafoam would probably do the trick, but the question still remains if it would be safe for the plastic. You'd have to find the plastic ID stamp to know for sure.

Seafoam's active ingredients are Naptha and Isopropyl Alcohol. (I understand that the Naptha is what really works on the carbon deposits.)

Formula 88. Half gallon of that and half gallon of water. Submerge it in a deep pan so the entire intake is under the mixture. Make sure its filled up inside all of the runners. Let it sit for a couple hours. Then use a toilet brush with a bendable/flexible handle to rip it in and out of each runner. Then hose that all out of each runner. Then submerge it again for a couple hours and repeat one more time. Rinse it out and dump as much of the water out as you can by tumbling it all around. No need to let it dry.......

I've done it a couple times that way......works perfectly.

get a big deep pan ,fill it with some degreaser and water .let soak for a couple of days .turn it over .then remove it and spray it with a hose .

Naptha itself may work! Thank you



Nope


Nope....I let it soak in a bathtub but no bueno





Thanks, Ill check out Formula 88!

I have tried several different degreasers an nothing works. Ive used the toilet brush thru the runners but needed a chemical to break it loose.

Formula 88 is WAY better than any other degreaser I've ever seen or used. Much stronger than Purple Power.

Home Depot.....sells it by the gallon. Get two gallons and a spray bottle, you'll use it for everything. Cleans an engine very easily.

You can't go wrong by looking for that plastic ID stamp first and confirming the material.

Starting with the dilute Formula 88 or a lighter degreaser is probably a smart move. That will be much kinder to just about anything than going at it with Naptha. (And even then, I'd still be cautious and test a small area first, being sure to rinse it thoroughly when done.)

Thanks! I will test it but Ive tried all kinds of things I just didnt post them lol. I havent looked for the stamp yet. Ive been hoping to hear someone say "This works for me" which is what LS6427 said.

The ONLY place lacoal that carries it is advance...no onder Ive never seen it. Home depot has it in their database but I cant pick up or order it. $7 a gallon, not too bad! Ill pick some up today if they are open and see how it goes.

Thanks guys

Your Home Depot doesn't have it......?

Man, all the Home Depots around have half an isle dedicated to it.

I also used gasoline to clean my intake once when a ton of oil was in there from a failed open PCV valve. It won't hurt it at all. Just don't let it sit for hours. Submerge it and fill the inside runners completely for about 5 minutes. Use the brush on the runners. Submerge again for 5 minutes. Then rinse with water.

At that point, I'd go for kerosene, if the OP has it. It's a lot less volatile and a lot safer to work with.

Looks like formula 88 isnt even sold in VA lol. Odd, but I called everyone and no one has even heard of it.

I was wondering if Kerosene. I have access to a parts cleaner
