rickyboy, Nice mate
Julia, Mine had done approx 130k and I knew it hadn't had a rebuild. I wanted more power and thought that there was no point doing that to an old engine, so went for a full upgrade rebuild. So mine was more of a prevention with a view to further upgrades.
If your engine is working well, set-up properly, and you're looking after it right (as in regular servicing and fitting/ using quality parts) then there *should* be no reason for a rebuild. From your earlier post, the car's been well looked after before & you are carrying this on, so just see how it goes & what your plans are going to be with it.
