Yea a mechanic friend of mine said to get a 2-3 gallon jug fill it with water and connecta very tiny tiny hose from that to the pcv line using a t fitting.. So the intake will suck it up.. Then go on the freeway and drive it for like 150-200 miles and that will steam clean the engine

Does this make sense ?

you'd need a very tiny line to not quench the combustion too badly while driving.
most people do it the same way we do seafoam, just slower.

Yea myt valves were pretty dirty.. thats why i asked if i could use brake cleaner on the intake valves when i had the manifold off.. My valves looked like this almost.. not as bad but close.
