In a word.... Don't. I ended up changing the whole head after I snapped my cam..

Pain in the ass as all the components / surfaces are mated and don't like new parts.

hmmm if I'm doing that may aswell drop a 1.9 in, cost wise anyway, was hoping to see what I can do with the 1.8 though

[kernow_joe]

Anyone else got any input/ advice?

Try putting an xud one in, lubing everything up and torquing to the specified poundage. I have changed cams before and not had an issue, many people seem to overtighten (think haynes says 15ftlb) the retaining braces though which cause no end of wear/issues. Make sure you keep the same retainign braces too as their matched/all ground as a set. Once in, move the pistons down in your engine (as to not foul valves - remember how to put it back again though) and then spin over with a 16mm spanner to check the tightness, see if its similar to your previous cam, if not then the tolerances not be working in your favour....

No problems at all Joe changing the cam...changing the caps is where the problem is or over tighening the bolts...just makes bearings pick up / cam break....the XUD 9 cam will fit your xud7 but cant reember if the pump bolts on / oil feed is there?

Tbh id just drop an XU9 in it....

[kernow_joe]

nice one cheers Dave, is annoying only want to be able to fit a vac pump on the end of the damn thing! bit worried I may kill it though bit more then I've played with before.

Will search around do a bit more reading I reckon

---

pump will bolt on grabbed one from scrappy the other day and eyed it up, bolt holes are all there, and think need to remove an allen key to open oil feed,

well it seemed a cheaper/easier option to keep the 1.8 in there and the engine seems so good seems a shame to scrap it

[darrenjlobb]

Ah yeh if the allen keyd brass fitting is there ur fine Bets on it rounding out if it does just drill hole in it for oil flow

[kernow_joe]

its sounding an easier job to drop a xud9 in ....

[darrenjlobb]

If you need an XU9 I think i might know of one being broken.

[kernow_joe]

oh really? this sounds interesting, if you could find out that would be amazing
