I put this in another thread but figured it would get more attention on its own.
Ive got a can of this stuff sitting in the garage and might have some time this afternoon to do it. Majority of reviews I have read are very good but every now and again youll see someone say DO NOT put into your crankcase, dispite the instructions telling you to add 1/3 of it to the oil. Fuel is fine, intake is fine oil NO. Anyone care to comment on that? I got a new PCV and EGR valve to replace this weekend along with an oil change im going to do, should I just stick with doing those things and seafoam in the intake and fuel and leave it out of oil? I wanted to do the seafoam before I put the new PCV and EGR valves on. I dont want to screw anything up and have it clean the crankcase soooo good it starts leaking somewhere. I have an 04 5.7 hemi with 105k miles on it. Thanks
