i just wanna put it through the intake ( NOT THE CRANKCASE ) and im not sure if I have to change the oil afterwards?..

 

Some may work past the rings and get in there anyway. Why not wait until yer next oil change is due, and run it through just before.

 

Not if you run it thru the booster - the line at the end of the stainless cable in the pic -



Here a better pic - Most people , run it thru the booster - this line here -



Careful , I wouldn't advise it and would never do it myself - To many adverse effects - damage that can be done and you won't know until much later and when it's to late .. Hydro lock, cracked pistons , leaky injectors o-rings (keep an eye on the top o-rings).

If you end up needing a new motor in the near future after running that snake oil thru your top end - You can get a good used one from car-part.com. They'll find one close to home for yuh, you just type in your zip code and they search from your area out..

Good luck

 

Thanks!
