    does anyone know if you have to replace the bolts on the S/C and I/C after they have been removed to clean them?

    you should replace the IC to midplate bolts since they're TTY and could be ingested into the engine if they come loose since they're on the bottom of the midplate, but you really don't need to separate the IC from the midplate to clean it. The rest of the bolts you're perfectly fine reusing.

    Those bolts would be the 11 that hold the inter-cooler to the intake right?

    Interestingly enough, I was chatting with a Mercedes-Benz mechanic the other day that just happens to own a Lightning. He told me that there was no reason to remove the S/C to clean the inter-cooler.

    How I ask? He said that they have a aerosol version of Sea-Foam that you can spray directly into the crank case air recycle port that everyone typically puts a air/oil separator in-line. He stated that the S/C circulates the Sea-Foam in such a manner that is cleans the entire core and the intake valves.

    I'm curious to see if this method really works. I use Sea-Foam in all my vehicles, love the stuff. I'll have to crack the S/C and take some pics before and after treatments to see if it's true.

    have you ever cleaned an intercooler the traditional method? There's a LOT of oil that can get caked up in them. Why push all that sludge and crap through your entire motor when you can clean it out BEFORE it even sees your valves and cylinders.

    clean it out traditionally, and tell me if you'd want that sloppy crap sucked through your engine just to save a little time on cleaning lol

    Yeah, I've done it before and have tried very hard to keep oil out (mainly because I didn't want to do the traditional method anytime soon). Mine should be fairly clean. I doubt I have more than 15k miles since the previous cleaning 2 years ago.

    But you are correct, I would not try this if it's never been cleaned before. Even with the oil/air separator in-line from close to day one. It still had a good coating of varnish. I didn't have any caked on deposits though. It only took about 30 minutes and a couple cans of cleaner and it looked new-ish again. Hopefully this Sea-Foam method will be the easy way to maintain that clean.

    I'm getting about due for a plug change so no better time to check it.
