Valve tick at idle
#11
Oh, huh. I only drove around for maybe 50 miles with the seafoam in. But i didnt put the other half of the can in before i changed it either. Maybe ill try that before my next oil change. It also seemed to get a little worse after i did the timing belt and the oil change. I did gain about 1 psi of boost and 2 or 3 psi of vaccum though after doing the oil change with Royal purple. It almost seems like it got a little louder though.

If it was the cam chain tensioner, wouldn't the ticking not go away after a few minutes?

Yeah ive also got another problem but not sure what it is. Might be the cam tensioner starting to go. When i rev up the engine past about 4500 or 5k rpms, and let off the gas it makes a grinding noise just down to about 4 or 4500 k rpms. Unsure of what it is. I was thinking it could be a crack in the turbo or my cam chain tensioner. I might change my plugs also, they look terrible and i also need a new VC gasket.

Indicator of the cam chain tensioner going out is a rattle/tick from under the valve cover where the chain is usually apparent at idle and a change in pitch when getting on the gas but disappears after it revs up. I guess if it's bad enough it could make noise under any load/rpm. 0w40 is probably a good idea for any higher mileage 1.8.
