Mk4 Exhaust Manifold 2L Petrol

[drrobbeattie]

Hi all, I am looking for advice on replacing the above on my old camper van. Mine was cracked when the camshaft got replaced. I had a look online and this has the correct part number (92 - HF - 9430 - AA) but it's reasonably expensive and I am not sure of the quality:

Not sure if the Mk3 one could be modified to fit:

Any advice would be appreciated. I did a breaker search but it came up dry. The old van runs well and has about an inch of waxoil on the bottom now. It's a bit of afire hazard probably. But rust is not an issue.

Thanks
Rob.

People have managed to weld cracks on their manifolds so it might be possible depending on how bad the crack is.

The mechanic who cracked it gave it to a welder who has made a pretty neat job. The crack is maybe 10 - 15cm long. Not sure if he welded it or brazed it though. I did not look closely. It looks pretty solid so I am inclined to just forget about it. If there was a cheap enough replacement then I would go for that. But given the age of the van I cant bring myself to spend 400 euros. Sounds perfect now though with the new camshaft so hopefully get a few more years out of it. It's been very reliable.

Thanks

Was it cracked on the top ?

[drrobbeattie]

Yes on the top. I assume he was hitting it with a hammer.

PS Looking at this https://www.fordopedia.org/parts-catalo ... -ohc/B1.20, the gaskets seem the same right through, which would make me think that if the worst came to the worst then the manifold from another Mk could be modified. Maybe an adaptor of some sort. Not that I will be rushing out to try it.

Common fault the heat shield causes the manifold to overheat and crack

I was speaking to a mechanic friend of mine. He said the same. Said he changed a lot of them back in the day. Same for camshafts.

Drill a few hole in heat shield seems to cure problem camshafts no problem as long as oil changed every 6k
