some of you may remember me inquiring on running atf instead of oil for a cleaning of the inside of my engine.
i changed my oil this weekend and did just that.
results are pretty impressive. whati did was drain my existing oil and replace my filter. i added 100% atf to my engine and started it up. the oil light went out after 4 seconds (normal for an oil change) i then kept it at 2000 rpm's for 10 minutes and drained it out. the atf came out thick and chunky, solid chunks were visible.
i removed my pickup screen which is very easy on a porsche (1 bolt) and it was about 50% clogged with solids. i cleaned and replaced it,then filled up with rotella t and started it up.
note: the following may be psychosomatic.
it seems as though my valves have less ticking, and i have less blowby. the inside of the engine IS cleaner. i see about a 50/50 mix of black solids and alunimum where it used to be 100% black inside. i had no fears of solids comming lose and clogging oil lines, as this is whatoil filters are for
my oil pressure afterwards seems uneffected, maybe a tad higher though.
i took the car out for a thurough beating on the backroads, and nothing broke. i dont notice any abnormal noises (no rods or mains knocking).
the only thing that worries me is the lifters are ticking less. i think perhaps the atf dissolved some of the valve deposits which made the valves stick into the seats farther and this took up slack in the valvetrain. this is only speculation, as i will have to climb under and adjust the valves to find out is the clearence went down or not.
