I had new seats cut in the head on my 350x along with new seals. I am a chrysler mechanic but dont do much engine work (and no motorcylces), let alone rebuilds & valve jobs. Anyways I thought the one intake valve looked crooked. So some of the guys in the shop told me I should fill the head w/ solvent & it should not leak out past the valves. Well, it did. Is this ok? We re-lapped the valves & it leaks less now but still trickles out. Its more noticeable on the intakes bescause the carbon in the exhaust ports soaks up the solvent. I read in my 350x manual that the valves are hardened so I was thinking maybe the valves will eventually seat themselves against the softer seats, kinda find their own home after a while, is this the case, or are they supposed to leak a little bit?

In theroy it shouldn't leak.In reality there is no such thing as a perfect seal.If it seaps slightly its ok,if it drains the solvent in 10 minutes somethings wrong.

 

I have heard that these valves are surface treated, not actually hardened in the conventional sense. You might want to look into this before you reassemble it. I don't know for sure, but I would check into it.
