Carbon-Fiber Buildup
Hey guys-
My 86 NA has 255,000 miles on it (55 K on the re-built engine) and I was wondering about carbond fiber buildup. As far as I know the car hd NEVER been cleaned out (besides oil changes) and I was wondering if there would be alot of C Fiber ****. If so, how can I clean it out?

Have you ever heard of prolong. It's an engine additive that is supposed to remove carbon build up. Put that in your next oil change and be a little rough while driving and it might remove some if there even is any.
I wish I was driving!

PER Blake Qualley:
Remedial Maintenance. When the engine is really carboned-up, just driving it properly and running some injector cleaner periodically won't cut it. The "ATF trick" falls into this category. The better approach, as taught to me by Rob "Pineapple" Golden (Pineapple Racing) is to "steam clean" it with water! Just grab any small vacuum line and dunk the end into a bottle of
water with the car running (warm it up first). You need to keep the revs up around 4,000 rpm to keep it from bogging down, but the engine will suck water in, which will instantly turn to steam and clean the engine amazingly quickly. The engine will suck at just the right rate to do the job, but not enough to hydro-lock the engine. Do this outside as steam will billow out
the tailpipe in huge volumes (water expands greatly when turned to steam). The nice thing is that this is an instant cleaning process and the high-revs will usually knock all the carbon out the exhaust. Be warned, however, that sometimes carbon buildup is actually protecting seals and that by removing it, you might uncover a problem with the engine (same as with ATF). Do this at your own risk, obviously. When you're done, you should really feel the difference -- unless you've been doing the Preventive Maintenance regularly.
I'm sure Blake would want me to say that ALL CREDIT FOR THIS METHOD GOES TO ROB GOLDEN OF PINEAPPLE RACING.
