I was thinking of running an engine flush thru it to try to clean the build up, but wanted to check here with you guys first to see what kind of flush you would recommend.
I also realize that the best/professional way to do it would be taking the valve covers off and cleaning the valves manually, but I live in an apartment where it is difficult to do major work on a vehicle. I also dont have alot of monies to pay someone to do it.
thanx again for your assist.

Before you change the oil ldrain a quart of oil and add a quart of ATF and run it. Barring that you could add a quart of diesel fuel and run it at low speeds for a while. YMMV
