So I was driving home earlier and due to a van coming the other way down a country lane at a stupid speed I hit a rather big pothole, or 2 :angry:
The rim doesn't appear to be damaged and the tracking is still ok, however when I pulled onto my drive something didn't sound right :undecided:
There was a slight rattling/tapping noise coming from the back of the engine bay, my initial thought was that its the manifold heat shield. However when I revved the engine a little it got worse (as you would expect), but back box was rasping and popping a bit as if the exhaust was blowing somewhere.
I took the car for a drive around the block and sure enough it sounds like the manifold is blowing :angry:
Is it possible that hitting the pothole has caused a crack in the manifold? Bearing in mind i'm on hotuning coilivers that are as solid as a rock, so any minor bump in the road is amplified massively anyway.
-
a pot hole could easily kill a manifold! and there are not usually repairable (my passat one is cracked and I've tried all sorts to fix it!)
best get under the bonnet and have a check around! (hopefully it wont be serious?)

Bugger, thats what I thought :cry:
It'll have to wait til the weekend now, it's dark when i'm not at work through the week :sad:

Grab a second hand manifold. U can't repair them. Weld them and they will expand when warm and the weld will fall out.

best thing about owning an old car... bits cheap and everywere! ebay it!

Ive welded no end of cast manifolds and never had a problem :undecided: Give it a good prep gouging the crack out a bit better to get better penetration and use some 2.5 Ni-CL cast rods to fill and the same again to cap.
Never had any weld fall out yet :cool:
Cast rods are expensive :undecided:

I stand corrected then. :cool:

cumbria and roads = POTHOLES I KNOW..
-
I feel for you man :( Hope it isn't too bad to fix!

Well I'm afraid I can't advise heading south to get away from them - we got some pretty good open cast mines in the roads down here in Devon too! :sad:

Tell me about it :angry:
Get on the Cumbria County Council website and report any near you!

Cheers, i'm hoping i'm just thinking the worst, I had a quick 10 min look earlier and i'm thinking the noise may be the manifold heatshield. The more I hear it the less it sounds like it's blowing. It sounds almost like the tappets, but I did the screwdriver test and i'm pretty sure it isn't :undecided:
-
The screwdriver test??

The screwdriver test??
I was wondering that too.

The screwdriver test??
Engine running, one end of the screwdriver placed on various places on the rocker cover, ear against screw driver.
It helps to identify where rattles can be, i.e. if the tappets are noisy when you do this the noise will be louder in your ear because the sound is amplified through the screw driver :wink:

poor mans stethyscope.

Yup, but works very well and its cheap/free.

dom it could be the manifold heatshield as the ally cracks and loosens the bolts so it does rattle a lot on tickover.
-
Is it blowing if not then as Len said you could have loosened the heatshield

Yeah, i'm swaying towards that at the moment, I'll have a proper nosey at the weekend when I have some daylight. If it is the heatshield, is there any way of sorting it? I used jubilee clips on the cat heatshield but the manifold one is a lot harder to access :undecided:

Initially I though so, but now i'm not too sure. I may have just been thinking the worst, a couple of others have listened to it and said that they don't think it's blowing. As above I'll have a really good poke around at the weekend, hopefully it'll just be the heatshield :smiley:
