blown engine???

[iowasux03]

well lets see i used to drive a 1990 plymouth laser 2.0 RST with 174XXX miles the car is bone stock and i got it bout 5 monthes ago i was working on replacing alot of things before i started modding it i replaced timing belt and all other belts new ign. coil and a new water pump 2 days ago and i went down today to pick up the car from a buddy of mine who did the water pump for me and when i got their i hopped in it and tryed to start it up and it turned over but didnt start and made a really funny sound and when i went to try to start it again it just clicked everytime so we yanked the timing cover off and the belt was really loose and then he tryed to turn the timing gears and they barley moved but more like rocked back and forth and after awhile he got it them to turn and then they would just get stuck we figured it was just a tensioner broke lose and was stuck inside gumming it up but the belt was under both tensioners and their was alot of oil underneth the car it had a small oil leak but i dont know if the engine is seized or not(because the gears wouldnt move at all) but then again i dont know much about dsms so i came looking on here for some answers and didnt find anything that could help me very much but

im going to expect the worse and say that the motor is seized but i was looking online for motors and i found a 1992 laser 2.0 NT auto with a bad tranny for 600$ and i was thinking about taking the tanny out of mine and converting the 92 laser to manual with a turbo.

would this be a good idea or should i just rebuild the engine?

oh and a few other things that might help. my mechanic said he had the car running for about a hour and a half to 2 hours before i showed up and it ran like a champ expect for a rough idle when i got their the exhast mani was still warm and he burned a about a quater tank of gas so idk if that will help i would like to daignois the problem

things ive considered so far

seized motor
bad starter... idk how this would cause it but its a thought

and at the VERY VERY VERY bottom of the list Crank walk but i dont know much about this problem so dont bash me please

but any thoughts at all would be very helpful


oh and p.s. sorry about my spelling its not my strong side haha

check your timing marks and see if they line up. sounds like it skiped a tooth. did you replaced all the timing belt components or just the timing belt and accesory belts?.

 

[assault187]

Pull the timing covers off and check timing marks to see how everything looks. Try to rotate the motor by the crank sprocket rather then the cam gear. If you can rotate it even a little bit, then the motor has not siezed, but possibly skipped timing. If the motor is out of timing, the valves and pistons may kissed. Was the timing tensioner replaced? broken balance shaft belts may also lead to skipped timing.

Crankwalk on 1G's is pretty uncommon, the 2g 7 bolts were more prone to having this issue due to design. If you would like to know more about, just do a search, you'll find days of info.

Do some digging then post back with your findings

It honestly sounds like your mechanic screwed up. Is he an actual shop or just a friend that did it for you?

man that suck's it sound's like your mechanic screwed up i would find out the extent of the damage before replaceing with anouther used engine.

thanks guy for your replys but the mechanic did have his own shop where he used to live and hes saving up for a new shop but the timing marks did line up and when we changed the timing belt the balance shaft belt was snapped and was wrapped around the pulley real bad but the crank sprockets do move but they stop when they get to a sertin spot and i didnt change all the timing componts i just changed the timing belts and accesorys but im going down their today to talk to him and il get back to you guys thanks

so i just found out that the starter is shot

and i did some digging about jump timings and i think that might be my problem but i coulndt find that if i just tryed to crank it over but it wouldnt run if i bent the valves but i know they hit if it jumped...

could they hit with enough force to bend the valves if i just cranked it over withouth it starting?

but monday were going to try to put the timing belt on and manualy turn the timing sprocets to see if everything is lined up and if we cant find anything out of aligntment were going to try the starter

hopefully all goes well

Sorry to tell you but if you skipped a tooth on your timming, you got bent valves. Just hope for the best. Goodluck
