seems like problem after problem with my car latly.. im doing a tune up tomorrow on my car (plugs, wires, dist cap, rotor, and an oil change) if its sunny/nice out. now with the problem.. where the exhaust manifold connects to the y-pipe there is these exhaust donuts.. and they keep cumbling and it keeps leaking from this same area time after time.. first time i used the stock one, second a differnt bigger one.. and this one right now i modified myself and used some metal sleaves on one end so it wouldnt leak. but that failed now to ( i put it in around december) any ideas on what i should do now?

find out why it's disintigrating so fast, could be the bolts aren't holding, do you still have the bolts with springs on it?

Dcalado_

bolts with springs? iv never seen those before.. never were on the car when i got it.. could it be from over-tightening?

archemedes

maybe, the bolts for the manifold are supposed to have springs on them so that if the exhaust moves it doesn't kill the donut

Dcalado_

hmm as far as i know the manifold bolts are the original ones..(minus one because it is broken in the head) but its not leaking at all from the manifold just where it connects to the y-pipe.

archemedes

the bolts are where the manifold conncts to the y pipe

JesasaurusRex

they dont have any springs on em dont listen to him

they seriouslly dont tho

archemedes

they should with the 2.8 (all of the ones I had did as well as all teh ones I worked on at the dealership) they are basically a stress releiver

archemedes

and you can't see the springs most of teh time (it's a pain to see the side of the flange as iit is)

JesasaurusRex

well i know mine didnt have any springs and my exhaust was stock so i doubt it was ever removed

JesasaurusRex

on another note, i stripped one of my timing cover bolt holes in my block :banghead: imma get another like 1/4" longer bolt hopefully itll thread

archemedes

how do you strip that?

JesasaurusRex

over torqued i guess, maybe other dude did it cuz i coulda sworn i only tightened it as much as the others but guess not

ok.. got some more information, my dad owned the car before me... and he had some exhaust work done on the car because of leaks.. the guy that worked on the car told my dad he couldn't fit the original bolts back in so he was using some other bolt. my dad not knowing they were special bolts just said ok. so basicly i need to find someplace i can get those bolts

archemedes

napa should have the correct ones
