Good day tuners im having some concerns with my 4g18. I have had to replace my valve seals due to number 1 cylinder leaking. I bought the original head kit and had it installed. One week later after installation my car didnt want to start. I removed the 4 spark plugs and realized that it was soaked with oil. I had the head removed and found all the intake valve seals leaking. I bought another kit had it installed with professional help and the same thing happened again. I would like some suggestions as to what can cause the valve seals to keep leaking. I know for sure that it cant be the valves cause it fitting snug on the seals.

Sounds like something is swelling those seals, are any other seals leaking? Front or back seal?

Use grey silicone to stick both mating side of the plug seal and that should fix your problem
