Good idea? I have a nice week off and I was going to take off the intercoolers and clean them out. What would it use to clean them? I dont want to wash them with something that will make them corrode. I did a pressure test of my system and failed to look up a good write up. I ended up throwing a bunch of oil in my intake and got everything is covered in oil. It made a pretty killer smoke trail for about 5 miles.

Also just out of curiosity, if i take off the intake to polish and clean, could i get away with just replacing the main gasket? Or do i need to replace all of the fuel injector seats and other pieces?

Oh I forgot my vac leak issue...

So i did the pressure test and found a leak in the sump pump on the PCV and another little leak on a T-fitting. My DV was leaking so i fixed that. The crankcase is leaking out the side next to the TIP, that half moon hole. Can i just fill that up with silicone sealant?

I checked the idle trims (block 32) and it was reading +8%... it didnt make any sense. It has been throwing the lean code. Then I looked at it another time and it was within spec +1.8 or so. This was before i touched the engine. The MAF is reading within spec and the O2 sensors are reading as well. Im a little confused by it... will fixing the crank leak and PCV fix it? +8% seems kinda high for a couple little leaks.

Thanks

 

Haven't clean out the ICs on the TT yet, but I have used gasoline on other cars.
Cap one end of IC, pour some gas in, cover other end and shake.
Repeat until gas comes out clean.
Then just let them dry completely before reinstall.
There is prob a better way, but that always worked for me.

 

Almost anything but diluteable degreasers, unless you REALLY dilute them. That stuff, like purple power, mean green, etc etch aluminum in their stronger states.

Kerosene is a safe bet. Works about as well as gasoline, but w/o the risk of blowing your face off in the event of an ignition source.

When I cleaned the sparco IC I bought last fall, I did it at work with lacquer thinner (because we have a shitload of it at work). That worked well, and since it evaporates easily, a quick shot of compressed air had it completely dry, and ready to install on top of my TV.

Yeah, I'm a little behind on my projects.

 

You could always try this method...

Haha.... I dont care what someone else says, why would you suck sand into your intake?!!! That has to be the dumbest thing I have heard car wise.

Could i use a gallon can of carb cleaner and use that? Im just worried to use something that will eat at the seals. But if I use lacquer thinner do you rinse out the intercoolers with water or do you just let them air out?

 

Anything like that will dry out faster than water so you are better off just pouring it out and letting them air out.

 

I blew them out with compressed air, but that was partly because the car I got my intercooler off of didn't run an air filter. The IC acted as an air filter as dirt would stick to the oily residue until the thing was damn near plugged. I was blowing chips of yellow line paint out of the thing!

If you're just getting oily crud out, a good rinse, and then set it in the sun for 20 minutes or so should evaporate all the lacquer thinner.

 

that will never get old.... EVER
