![]() as for bending valves at high rpms.i don't think luck has anything to do with my sephia not bending valves when i was revved to 6,000 rpms when my timing belt sheered 19 teeth off of the belt at the crankshaft. i have posted proof FROM KIA, not some aftermarket parts information BS, that this is non-interference. It might also depend on rpms when belt breaks.Īs for if this engine is non-interference or interference. mine, t-belts on sephias, does damage to "MOST" owners. We all have our own opinion and experiences. Besides, he knew if valves where bent, I was parting them out, then scapping the rest. Confirmed by best friend mechanic, that half the time don't charge me for work, (if I help) so its not like he was trying to make a buck off me. ![]() I personally trashed 2 sephias, becuase of broken tbelts. Id personally like to see his pics, for proof that it bent valves. Lets see some pics of that broken belt and motor opened up for us to see, just like lets see those bent valve pics. If your at idle or just above your odds are better not to bend them, but if your way up there, theres no way. Even cars that are non-interference could bend valves, if at high rpms. This is the way I see it, some people get lucky (yes there is luck in this world) and some bend valves. How would it? That wouldn't make the pistons move anymore than a taken care of vehicle. so what the guy didnt change matinence items, that has nothing to do with a t belt bending valves. Keep in mind this article only applies to the 1995-2002 Sportage, 1994-2001 Sephia, and the 2000-2004 Spectra.Įven if you dont take care of it, that wouldn't make this case of bent valves because of broken t-belt any different. All other Kia engines are "interference engines.” The valves may interfere with the pistons if valve timing is off. The Sportage and Sephia/Spectra are the only "freewheeling engines." The valves do not interfere with the pistons if the timing belt fails. Tech Line tells us they get a fair amount of calls asking about valve/piston interference on our engines. Subject Engine Valve Timing Interference. P0300 - Random/Multiple Cylinder Misfire DetectedĮN9000 - MIL ON (Malfunction Indicator Lamp) Gr./Sys./Comp Engine Mechanical System / Timing System / Timing Belt feel free to look it up for yourself and read it on if you still need proof that this is direct from KMA/Kia Motors Corp. today i was browsing around on our GDS at the dealership on some info on a sportage i'm working on and i ran across an article in the tech times section from 2005 that basically proved me right. i was asked, in the last argument, to prove that i was right on this subject and if i couldn't prove it then i basically didn't know what i was talking about. You will get a few different opinions on this subject, so its basically up to you.There has been a number of times on this site where there has been arguments and questions over whether the T8D engine in the sephias and spectras are interference or non-interference. Just do it all when its all taken apart for the tbelt. ![]() You don't have to, but what if you replace that t-belt and a few weeks/months go by then it goes bad? Well there is another few hrs of work you need for the car again. you cannot easily diagnose a bad water pump bearing yourself.Water pumps usually fail in 1 of 2 ways: either the bearing for the pulley goes, or the gasket (or seal) behind the water pump begins to leak. Some water pumps are driven by the timing belt (like this one), which is under a plastic cover. This is a good time to get a new water pump, too, unless it was just recently replaced. If the water pump gasket is leaking, it must be replaced. ![]() Visually check the water pump (it's located behind the pulley) for signs of a coolant leak. By the time you can feel play in the water pump pulley, you may also be able to hear the bad bearing when the engine is running - there may be a low-pitched grinding noise coming from the water pump pulley. If there is, the bearings are going and it's time to replace the water pump. Grab opposite ends of the round pulley and check for "play" (looseness): Try to rock it back and forth. This is a should be to avoid costly repairs down the road if it should fail. What I have been reading is most water pumps either need to be or should be replaced around 100K miles.
