Cam and Balance Shaft Spacer Bushes
Hi Folks,
In the middle of a front end seal, waterpump and belts job on my 944 Turbo and wanted opinion on replacement of the spacer bushes.
On the 2 x balance shaft spacer bushes I can feel a very slight ridge when running my nail back and forth across the surface (left most bushes in photo)
On the camshaft spacer bush I cannot feel a ridge with my nail even though there is a line marked into the surface (right bush in photo).
So replace all three or just the balance shaft spacer bushes?
Thanks!

does the oil pump drive show similar wear? I believe some motors have an odd size race so you might measure what you have prior to ordering.
Mercedes makes service seals that changes where the lip rides which is pretty awesome when the ridge wont polish out with 600 grit.

I'd normally replace. However, if you can set the radial oil seal at a slightly different depth, to run on a different part of the bushing, then that bushing can be safely reused. Good luck!

Thanks Thomas - I've managed to get 1 x genuine porsche balance shaft bushing so far for £20 so pretty happy with that also can see a 2nd one for £27 and the camshaft flange is a bit more at £36.99.
Problem with those sets I've seen like the one you posted is they are for the earlier cars I believe as the flanges are all the same size.
Later cars have a unique camshaft flange which is a slightly different size, my turbo is a 1990 model.
