Not wanting to clutter the other thread where I have used the head-still-on method to change my seals (here) I'd like to use a new thread to ask more advice from the wealth of knowledge on this forum. When I changed the seals the first time, the blue smoke was worse, not clearing at all with the engine idling on the drive. I had a look at what I'd done and realised that I hadn't correctly located some of the seals onto the tops of the valve guides. So I did it again, repeating the method but trying to ensure that they were tapped on properly. I use the same seals as they all looked ok without any damage. However the blue smoke persistsed - clearing after 200m. So I looked a third time yesterday. Here are a couple of pics. As you can see, two seals have lifted. If I push them back on they pull off with slight finger pressure. One responded to a firmer tap and wouldn't then pull off so easily but one of the new seals won't locate as well as an old one. So I fitted an old one - picked one that seems to drag on the stem (hope that means a oil tight fit). Put it back together a third time, reset tappets and left overnight. It wasn't as cold this morning but I still got 200m of blue smoke. Hmm... Now I suspect the new seals and wonder if anyone else has had poor quality ones? I paid £2.89 +vat each for genuine parts but they have absolutely no manufacturer marks on them and they were in a plain bag. I've asked the (reputable) supplier to confirm that they are genuine but that was only yesterday and no reply received yet. Can I suspect the seals themselves? It can't be too difficult to seat them properly can it? If my blue smoke clears after 200m then it can't be anything else can it? Got to get it sorted as it's very anti-social as you drive through campsites (or down the road past the neighbours).
