My bet is that the problem is still there. It could also be a bad intake valve guide. The cylinders could be worn or damaged or there is miss matched undersize piston in there. Any sound of piston slap? I won't get into the break in oil theories as that can start another winded discussion. When I put together an engine I'll start with a cheap oil since no matter how hard one tries we cannot ret things perfectly clean. After the engine is running and ready for service I'll change the oil and filter again and if the customer wants the Mobil 1 goes in. Do a compression and leak down test. Most likely the engine will need to come apart again.

It also shouldn't take long to bleed the cooling system. Check the archives for my past posts. I try to get it done before the engine warms up.

Hey Listies, I finally got my 2.1L long block with components from my 1.9L finished and It's Alive! It actually works much to my amazement. I'm in the process of dialing it in now. I've got the timing pretty close for now and I'm attempting to bleed the cooling system. One thing I'm a little concerned about is the amount of blue smoke. I haven't run it for longer than about 10 mins or so and that wasn't all at the same time. The guy I bought the long block from said he had it in his Vanagon but took it out because it was using a lot of oil. He said he fixed the problem ring but never used it again. I've got Mobil1 15-50 in it and I've read several posts on the Samba that the ring won't seat with synthetic oil in. In fact I've read that I can do some serious damage to the cylinder by causing it to glaze over and the ring will never seat. Can someone please verify this for me. The engine is running sweet, sounds good too. But it is spewing blue smoke, I figured it would but I have no idea what a reasonable time it should take to stop smoking. Any input from the brain trust of the list will be gratefully appreciated. I don't want to do something wrong at this point. TIA, Paul in Tracy
