yeah i wouldn't be to the level of paranoid about fuel being everywhere. i'd just blow out all the rats nest lines and do a couple oil changes on it after allowing the engine to drain the oil pan thoroughly.

Thanks for that. Lucky for me. I have all the emissions deleted so all i gotta clean is the oil cooler and oil pan then. On another note, by any chance would you guys know what throttle cable i can use from another car? I need a long one to loop it around. Since my TB is a Jspec. The linkage is fac8ng the opposite side. Thanks!

all the turbo throttle bodies are that way, you can look at the writeups on how to make a bracket to use the n/a throttle cable.

JDM it is:

forward hard line is from the fuel pump>fuel filter>this port
top line is crankcase ventilation
rearward line nearest the firewall/oil filter is the fuel return line

on USDM cars the fuel feed and return lines are switched, turbo or n/a the orientation is all the same with the exception of the backwards JDM engines.

the main seal may be ok once it airs out for a few days, but you will need to at least drain your fuel soaked oil now and put in fresh before you turn the engine at all.
JSPEC S4 engines are the only engines with a fuel system that flows backwards FYI

Nope. I can go take a pic of my jspec s5 if you'd like. I started a thread about this a while back. Was really confused why my fuel system wasn't backwards. Turns out only jspec s4 are backwards.

Edit: I guess i didn't start it but her you go.
