oh boy i have been pulling this car apart today and i see some carnage. previous owner strikes again, there are all sorts of little things wrong with this car.
to my horror i found the im shaft oring laying on top of the control arm and something was flinging around behind the pulley so i knew it was loose, no bolts. i guess all the interference on that side of the engine is what kept the im pulley on but it seems to have shaved metal bits away from the timing belt cover tin, water pump housing, etc. i'm not understanding how that is even possible since its toward the engine, i guess i will have to investigate further to see if they are even the right parts. so im assuming the oil pressure alarm went off when it started to work itself free and probably lost pressure at the im bearings, etc. there is some weeping oil but oil mark was still on dipstick. i emptied it today and found little metal specs. the gear end of the im shaft is messed up but it appears the im bearings are ok? i have seen those go dry and crack and break apart and score. these are smooth so maybe i caught it early? even when the alarm triggered there was oil splashing up on the head, although i guess it was less for that minute i ran the car to get off the road. what im wondering is there is a gear/cap that is held down into the block for the oil pump to ride through and im shaft to mate with. i was expecting it to be broken up to but if you can see my picture it seems to be ok? i don't see a hint of the wear the im shaft has. so was that made of a less strong material? do i have all the parts, it just sits in its spot in the block and rides metal on metal on the cap while bathed in oil? im thinking of just doing a timing belt job and fixing little things and moving on hopefully the engine is ok? also should i put in a better oil pump and a windage tray while i have it apart or is that needed? <https://lh3.googleusercontent.com/-Op4aalVWq38/VpRuBw-IpFI/AAAAAAAAAMo/J_y4Gr6eSn0/s1600/P1112107.JPG> <https://lh3.googleusercontent.com/-8ka6U7DJMKc/VpRuSUZ7U2I/AAAAAAAAAMw/19NzjDJxuk4/s1600/P1112109.JPG> <https://lh3.googleusercontent.com/-VQ19U3trXH4/VpRulCpW7eI/AAAAAAAAAM4/2-lF52WSgfE/s1600/P1112110.JPG> On Thursday, December 24, 2015 at 9:03:23 PM UTC-8, hollandphillips wrote: > > High pressure oil buzzer?
