Once the engine oil leak had been cleared up, it became apparent that there was, and always had been a steering rack fluid leak. Just weeping a bit from the bottom. Indeed one purpose of fixing the engine oil leak was because it could be masking other problems. The rack had been refurbished (see blog)  twelve months ago and was still under warranty. And at some point the hydraulic inlet thread was badly damaged. The steering specialists said to send it back. The could not repair it so they sourced another one for an extra hundred pounds and sent both racks back to me. To be sure of good joints I went to Pirtek in Milton Keynes to have some more metal pipes made (from the hoses to the rack. Plus new unions and special hydraulic washers that should be better than the old copper ones. This time I knew they took off the ball joints, so I did that myself and counted the threads - to replace them myself for a good approximation for the tracking. Once completed the steering wheel needed...

 An ititating oil leak from the PTO where the selector shaft enters. I was considering removing a striping the PTO to fix the leak. Or even finding a new PTO. I was told parts were not available for refurbishing them. but Chris Super Cooper Mobile mechanic . Suggesting looking to see if the seal fitted from outside. This seemed implausible. but with an inspection light and camera it was indeed the case. The old one came out easily and once out it was clearly metric 16mm shaft 28mm diameter seal, 7mm thick. The amazing simply bearings had two seals to match 16x28x7_SC (R21/SC) and an _TC (R23/TC) at just £2.39 each. The difference was that one had a lip for a dust seal. So I fitted that, even though the one that came off did not  have the extra lip. Job done, no leak. Let me say again how good Simply bearings are. They have a vast catalogue, which is very easy to look up seals by dimension - metric and Imperial. And delivery is fast.

 The gutter beneath the windscreen was leaky. Again, this showed up after the oil leak was fixed and I saw a wet patch under the engine. Well, wet it was - water. The problem does not show up well in the photos. After a couple of attempts this was the fix: 1) Throw away old rubber seal. 2) Clean as much rust as possible from the gutter, leaving several obvious holes. 3) Prime the metalwork with good quality primer (Rustoleum grey anti-rust primer) 4) Glue on some pieces of aluminium angle 15 x 15 x 1.5mm Using copious amounts of still all glue. One failed attempt had a lot of glue, but still not enough. 2 x 1m for £7.20 from EBay Metals shop 5) A couple of coats of rustoleum white 6) A new rubber from seals direct . 20mm bulb to fit panel 2.5mm to 5mm £21.35 incl. Vat and delivery Old gutter de-rusted and primed.
