[kevski]

Hi, just been servicing my 996 SPS (I just love the way that you have to nearly strip the thing completely down just to carry out a service and the fact that you have to get feeler gauges to perform miracle acts to measure the closing gap) anyway I thought I had got off lightly until I looked at the last camshaft and both opening rockers gone, plus the cam (

Looks like the engine had an oil leak there at some point as the back of the casing is stained and caused this to go.

So the question is do these cams come up vary often in good usable condition, or is it just a case of warning the credit card and purchasing new?

I only need the rear exhaust cam, which would probably increase the odds for the weight for a second hand would imagine a set being reasonable valuable as an upgrade to standard 996s.

Cams do come up on ebay from time to time, go check the site out and see whats there

Well i couldnt find any around when i needed them as they seem quite rare these days.

Cam cost me £300 and rocker i required was about £100 new from JHP.

Newman cams can make you a new one from the old, maybe it's less expensive than buying a new/used one.

there was a full set of cams on eBay other day.
The staining is most likely petrol tbh. The oil feed to the rocker area is pressured. You'd get a lot of staining if it was that.

Hi, ended up ordering new one, which took ages to come from Italy as they have changed their stock system and then was told the cam was listed as critical. Which got me wondering if I was going to end up as a long wait.

Yep £300 for the cam plus £200 for two rockers:-( but did notice the full set of cams on fleebay just after I got the exhaust one.


Paint was quite stained and ended up stripping and paint the back of the casing with 2 pack which now looks dead posh, also the rear cover had gasket goop on it so can only assume it leaked from there. Bit difficult to tell now, so will have to see how it goes.

Does make you think that cams should be pulled out on every full service to fully check the state of the rockers as two year use on a rocker that is just about to go and wont be picked up by just a gap check and the concequences can be the additional cost of new cams.
