Please Read Timing Belt Came through cover

PPM · Oct 21, 2009, 10:30 AM

Okay,

I was on my way to work yesterday stopped to fill up with Shell 93 and noticed some smoke coming through hood vent, popped hood smelled a little oil (possibly I have a cold hard to tell). Shut car off checked oil (it was clean and perfect just changed 1200 miles ago) turned boost down just to be on safe side 25psi - 20psi. Started driving to work about 4 miles into trip heard something come off car, thought maybe I hit something in road and hadn't seen it, standard unsprung clutch chatter makes it difficult to hear anything else. Stop car on side of road, slight ticking coming from motor, I decided to head home instead of in to work. Got about a mile and car felt like it lost power, more noise and smoke out of hood. I pulled over and cut car off cuz oil light just came on. Car was trying to stall as well. I started car one time and it cut off, I didn't rev or anything just idled out. I towed it home and noticed that my timing belt was showing, burned a hole in the timing belt cover and put several gouges in the serpantine belt was chewed up and oil spray not sure where it was coming from was all over the bottom of the motor. I am going to put everything back together and see what happens unless anyone else has seen this happen, i figure put together check oil pressure / oil pump reset timing belt, compression check, visually check valves / springs and go from there. Any ideas? Anyone have or hear of anything similar happening? I did change my timing belt about 20k miles ago, been to the track and had dyno'ed since then. I can't really afford a new motor or to miss work for that matter. So if I need a new motor, I am going to buy a beater car and put a whole build project on hold until tax money time. Thanks in advance.

any pics ??

Well if you got an oil leak in there it's possible the belt got all slippery and could have shredded off teeth or just little by little come apart. The noises might have been the belt coming apart but until you take it apart there is no telling. Is the timing belt still in one piece? Did you do the FULL 60k maintenance, including tensioners or did you reuse the old hydraulic tensioner?

Here are some pics for everyone. I did the full service all parts, tensioner, pulleys, etc. Gates Timing Belt.

that sucks. buy a beater, motor is toast. good luck.

05blue8 · Oct 22, 2009, 08:23 AM

The motor COULD definitely be toast but your best bet is to find the source of the oil leak, then get the timing back together and check the compression and go from there.

Thanks 05 Blue8. My plan is to order the part that failed in the timing belt assembly, it is the bottom right gear obviously from the pictures, the timing belt itself seems fine I will know more this weekend or maybe even later today if I get lucky my son is very sick so I don't have much free time right now. Put it back together as much as necessary and check compression. Even if my compression is bad, I could have potentially bent some valves but there was no metal in the oil so I think that is a good sign and I didn't keep trying to start or drive it cuz I am not that dumb.... Thanks everyone more to follow I will keep taking picks.

You have an interference engine, meaning that since your timing belt came off, your valves most likely made contact with your pistons. Who did your service? It looks like a hydraulic tensioner failure to me.

tweakdsm · Oct 22, 2009, 08:38 AM

PPM: seems like tensioner went bad or it wasnt tight , how many miles on the car? if i were you i would check compresion, best way to do? buy a beater, pull the engine out.

PPM · Oct 22, 2009, 10:44 AM

i did the service. I have owned several evo's and 2 talon's, 5th time doing it no trouble at all with install. New tensioner installed with Gates timing belt kit all of the parts are new. Really bummed out right now. I am going to get the beater and hope for the best when I get some extra money I will rebuild the motor. I am going to put together and check compression just for ****s and giggles. I new this was in interferance motor just hoped that I got lucky....

red evo8 · Oct 22, 2009, 01:21 PM

oem tensior when you did the install?

KevinD · Oct 22, 2009, 02:05 PM

oil pump pulley came off?

JohnBradley · Oct 22, 2009, 02:13 PM

Its done.

I am thinking you will find a bad oil pump, galled cam journals, bearing issues, possibly slammed valves. If it was powering down like that it was seizing up.

Christ... this is why I do not do this type of service myself... I am petrified that I could mess something up...

The best mechanic on earth couldn't have know the engine was going to toss that gear. As it is you are going to need an overhaul. The car was losing power and then the oil light comes on - isn't that sweet. Why didn't Mitsubishi save some more money and just leave the light off of the car?

DSM's used to throw the nut on the oil pump sprocket once in a while. It was common practice, although I never did do it, to loc-tight the threads and retorque the nut at belt time. Maybe that is a practice that needs to return.
