this is exactly what happened...
we drove the car to the dells & parked it for the night. the next day we were driving it around the city when the car started making a knocking sound. i had my husband, father, and brother look under the hood to see what the problem was.
after pulling the dipstick out, they seen that the oil was much lighter in color, milky, and thin in texture. it had a sweet smell to it. my father is a mechanic & said that there is clearly antifreeze in the oil. he asked how this could have happened & thats when i told him that i had the upper & lower manifold replaced. i asked him if that could have anything to do with the antifreeze being in the oil.
he responded with a definate yes saying that if the upper intake is not tightened well that the repair can definately fail.
he told me that with the knocking sound it was making that the engine could go at anytime. we drove the car home anyways, as we needed to get it home as well as the children.
we were not even 45 minutes onto the interstate when the car made a loud noise & turned off completely. my husband put the car in neutral & pulled over to the side of the road. we had a tow truck pick up the car & had it taken to the mechanic that did the work prior to the explosion.
it was after business hours when the car had been dropped off, so, there was noone to look at the vehicle at that time.
the next day i phoned the mechanic to let him know what had happened and that the car was there in his parking lot. he told me that he checked the oil along and also had 3 of his other mechanics check the oil. he said all had confimed that there was no antifreeze in it. he also said that there was no puddle of oil under the car, even after sitting all night.
that is sooooo unbelievable to me as the tow truck had puddles & puddles of it on his bed.
later that day, my husband stopped by there as well. he rechecked the oil & said that it looked completely different than the previous day. he said that it looked like used oil with metal flakes in it. he couldnt believe it!! he knew what he & the others had seen the night before.
at this point the mechanic had said that he still didnt know what was wrong with the vehicle. a few days later, he put the car up on the rack, took the oil pan and gasket off & phoned me to advise the the engine completely exploded. he said that there was pieces of caps, rods, metal everywhere. he recommended i get the engine replaced.
he also said once again that he didnt believe that the explosion had anything to do with the work they did.
again, the tow truck driver, my husband, my brother, and father seen the oil the previous day. there was no question as to what they had seen & smelled...after all, who would think antifreeze could be in oil anyways?? lol
i dont know what to do??? thanks for the responses willwren & compyelc4. any suggestions and/or advise is greatly appreciated from this end
