Ok so does anyone have the specs for an 07 scion tc's lifters. I got some knock goin, need to figure out what to do my buddy believes i have to adjust my lifters. If you guys could help me out and point me in the right direction thatd be awsome. Thanks.

 

what makes you (and him) think your need to adjust your lifters to fix the knock? id look for restricted coolant flow, a lean injector, a leaking intake manifold gasket, a bad knock sensor, a bad A/F sensor, that kind of thing.

 

hydro knock?

 

Lifters almost never need adjustment unless your head is coming loose or you cooked something in the engine. If it is making tapping noises then check your oil quality - if it is a real knocking sound then you may have some lower end damage . . . again check your oil. Make a video of it or a sound recording of the knock and post it here if you can so "we" can hear it.

 

if you got knock its from mac doing a sub par job on your install get some new plugs hook up the uego to the fic and i will tune it if its not already to late any way you can give more of a idea of what the sound is like and stuff like that

 

Also make sure its just not your "vsv" i believe its called. The emissions system on the car. My 08 tc makes a slight ticking sound, and has sense day one. it comes from this

 

you need to either post a video so we can hear it, or do a better job of describing what it sounds like. is it spark knock? clicking tappets? what?

 

The serpentine belt tensioner can make a tapping noise when it starts to go bad. Get an automotive stethoscope to figure out where your noise is coming from.

 

Ill make a video today, didnt have time to yesterday as i was getting liqoured up and passing candy to kids.

 

jezzzz don't get those two confused!
