I've got a blow coming from between the manifold and downpipe joint... but its hard to see exactly whats going on! wether it is broken or just loose etc... I can only go by feel rather than sight, it feels like there is some sort of mesh there. Can anyone shed some light on how these are connected before I start trying to take apart, as the haynes manual doesn't show a lot !!
Thanks

there is a gasket between the 2 halves, but doing it in situ is a pain becasue you wont be able to clean up the mating surfaces properly so you might not get a good seal. also the old gaskets are generally a right mare to get off in 1 piece too! if its leaking at the actual flexi part then you'll need to get a new downpipe, not a fun job :sad:
-
Im really hoping i dont need a new downpipe... its really difficult to see where to start while laying on the drive, really need to get it on a ramp.
before I get back under there, can someone explain how to get it apart ? i'm thinking cause of the heat any bolts are going to be a nightmare anyway !!!
Thanks

Threre is 6 bolts, if you remove the top part of the inlet manifold it will be a bit easier to undo them, I absolutely soaked mine with wd40 and they came off ok, you need to be carefull as they can sheer off then u are buggered, dont worry about the flexy bit, use wire wool to try and clean the faces, the wd40 will help clean them with the wire wool, I used some gun gum on the gasket to get a good seal.
-
ok.. thanks for advise, yep think i will cake in wd way before i start !!
may have a look this weekend if weather is ok !! my garage is packed with a mates house stuff at mo !!!
-
As mensioned soak it in penetrating fluid. plus gas is pretty good. Also use impact sockets as they won't round the bolts like normal ones. If you have access to some ramps or pit you can just about squeeze the down pipe out from under the car. Not an easy job though!! Good Luck :smiley:
-
just had quick glance before i get at it at weekend... I cant see 6 bolts from the top... I cant see any !!!

its 6 studs in the manifold, with nuts underneath!

OOOHH..... what you saying ? cant you remove the downpipe without the manifold ????? :shocked:
-
you can but you have to get to them from underneath. I got 5 of them out on my mates car using 3 extension on his breaker bar, the last one I had to use a spanner on, wasnt fun! 3 of em sheared off rather than undoing too.
-
Oh I see.... so its easier to take manifold and downpipe off then split them once off the car !! I get why people say its a squeeze to remove the downpipe now !!
-
yeah generally. trouble is on a 16v the downpipe has that big resonator box on it which wont fit thru the gap in the subby, so not really an option unless you drop subframe too :sad:
-
by the way, what's the purpose of the wire mesh wraping the flexi part?
-
If you want to remove the downpipe without dropping the subframe you will have too leave the manifold on. You will need alot of clearance under the car as you need to twist the down pipe to feed it out through the bottom. You will also need to loosen the gear change rod divice thing near the down pipe. You have to move this right over for it to come out. you will need a pit or a ramp to do this though :smiley:
-
I dont necessarely want to remove the down pipe altogether... I just wanna find out where the blow is coming from !!! the blow is louder when turning right (exhaust leans to left) and quiet when i turn left !!!
-
is it coming from the joint or the flexi joints
mine was blowing from flexi and when removed it looked like it was unwrapping and getting blown out of the joint and looked like wire wool if that makes sense
-
I undone the 6 bolts from the top with a ring spanner and a rubber mallet, I didnt smash the hell out of them tho just enough for them to let go then undid them by hand, no shearing! :grin: The flexy bit is there so the zaust can move and it blows from there for a couple of mins on start up

Its hard to tell tbh... it gets hot soooo quickly !!!
