kingjack133 Posted November 26, 2007 Share Posted November 26, 2007 Apparantly, if the timing belt breaks in a "non interference engine" , the engine will only stop running.because the cam would stop turning. I am under the impression that the valves and rods would get bent if the belt broke (because of the piston head clearence) and the motor would need a rebuild... is this true? And if it is ...is my 92 es300 3lv6 a N>I>E? Any feedback on this subject would be of great value toALL!....If the dreaded "beltbreak" happened it would be nice not to freak thinking about a monster rebuild bill instead of just replacing the belt.......

powerwave Posted November 26, 2007 Share Posted November 26, 2007 our saturn POS had an interference engine. we had a timing belt GUIDE, not the belt but the cheap POS plastic thing that was integral to holding the thing on, snap on us and the whole head ended up being screwed. valves were a sad, sad sight. i believe your 92 lexus has a 3vz in it, which is non-interference. those were here in north america from 92-93. the 1mz came around in 94 and was also non-interference until it was redesigned with vvt in 99. as far as i understand.

Hey powerwave, thanks for the comments. My wife had a 96 saturn and its the best parking lot car in the world. Too bad they didn t use space-age plastic on the inside(belt guide) like the outside because the doors and panels are tuff enuf to withstand shopping carts and hockey sticks no prob!.I talked to my genius mechanical knowledge friend and he explained the whole NIEngine thing to me. I realize why it s really called a CAM BELT. Correct? Sold the saturn and bought the lex. Feels kinda like a honeymoon....but then again ...i have alot of time on my hands.
