Can you please write a quick DIY, removal of the parts and rotating to TDC. I know its basic stuff but I'm just learning like everyone. Me and a buddy were able to install DPs today in 3.5 hours so were quick learners =D

that's what i was thinking... more uniform carbon then oily gunk like on others.

Good chance to test out if that sea foam stuff actually does anything...

Nice, thanks for posting.

When I did mine last week I found that the back 2 cylinders were much worst than the others.

Elie335i · 04-24-2011, 08:20 AM

better pictures man

dzenno · 04-24-2011, 09:18 AM

What you don't realize from the last 2 photos is how thick the walls everywhere but on the valves are coated including back behind the valves...valves themselves aren't bad but space around them is very closed up..

ianthegreat · 04-24-2011, 10:00 AM

It's only air, and in some cases meth or no2, that pass through here correct? So.. aside from the carbon buildup causing a sealing issue (simple compression test), I can't see how this build up REALLY negatively affects the engine.. yet. Obviously in extreme cases it could alter the flow of air, but is it really that bad?
