The tools I bought were off of eBay, made by a company called EWK Tool.
At £105.99 for the set these looked just the job, and appeared to be well made (for the money).
Unfortunately since I ordered, the listing was updated with an extra bit warning that these were not suitable for the 190. It didn't have the horseshoe shaped pieces for the primary belt sprockets for the 190 cams, only 2.0 and non-190 2.5
So I'm looking for a reasonably priced set of tools before I can continue with this, as I'm at the point where I need to lock the engine in the "Safe" position. Does anyone know where is best to get a set that fits the 190? I have no problem with buying used tools as long as they work!
