Hey guys, I opened the engine block from my Fiat Spider today (goes to hoard)… After I opened the oil tank, the whole 4 year old plumbers came up to me. (old thick liquid oil). Of course I let it off before.. yet there are plenty of leftovers in it. Now I thought.. Ok SB washing system and with high pressure cleaners the engine block and the oil tank cumshot… I don’t think that’s such a good idea or? Someone an idea what I can do without 300 rolls of cloth r to consume get clean? thank you
