Your always gonna hear weird and unusual noises when u have a modded car from time to time...lol This is normal :p When I hear noises every once and a while, it usually "fixes" itself.
Also check to see if your Oil Return line is clogged or restricted. I had a MAJOR smoking problem recently (Worse then smoke caused by worn/blown oil seals) and it was due to a restriction in my oil return line. Made a new line and no more smoking :) I also went ahead and change my PCV valve also.
Did u have any problems prior? Did u use a different brand of oil and spark plugs then before? I recently had a smoking problem and it was do to a restriction in my oil return line. When was the last time ur PCV valve was changed?
Where is he and why is he labeled by some as "infamous"? He sold bad parts to some on the board or something? I bought a rebuilt CT-9 from him before in the past and all was good and he was always friendly on Yahoo messenger, etc.
That oil return line was the culprit. The line was freakin' blocked -_- When I swapped manifolds, that caused the line to bend a little bit more causing it to be about 85%-90% restricted. Made a new line today and no more smoking :)
