I changed the oil & filter and the fuel filter. I noticed the fuel filter housing was very dirty. so I took it out and cleaned it. I didn't see any water in the filter housing. I also ran some "BG Diesel care" I bought a 946ml bottle and used just over half. Took about 40 minuets of idling to run half the bottle. The engine was already warm but after about 15 minuets of the "BD diesel care" diesel purge the rough idle really smoothed out. Still smoking slightly. I also bought a Diesel engine compression tester from Lordco. Its a Wilmar W89731. Unfortunately the pressure release button doesn't work and after 7 or 8 revolutions of the engine there was 420PSI in cylinder #4. So the quick disconnect will not work under pressure. After about 3 hours the pressure dropped to 100psi and I was able to pull the quick disconnect off and the pressure came out. I will not be testing the other cylinders until I get a new tester. The bentley manual talks about a leak down check right after the compression test in the book. It says its should only be done by a qualified technician and requires special tools. I'm a little surprised as this is a repair manual, are they assuming that the average person who owns this book is not competent enough to do a leak down check? The special tool is probably harder to find/easier to make but the principles are simple.
I should also note that if I come to a hard stop there is a puff of smoke once the vehicle stops moving. Also there is a hill in town I have to drive up and down every day. Its just over 1km long and going down hill the compression of the engine while in 3rd gear is enough to limit the car to 65km/h the entire duration of the hill. But once I get back on the throttle at the bottom theres lots of white smoke for a few minuets or until I give it a wide open throttle run threw a gear or two.
I checked oil levels and its right at the max line so I don't think there is too much oil in the car. And this was check on flat ground 15 minuets after the engine was shut down.
On a side note does anyone know where I can buy 3" diameter aluminum tube? Preferably with a wall thickness of 0.50" to .060" I've been looking at http://www.vibrantperformance.ca/ but the MSRP prices are very high and the only local distributor is Lordco and Lordco sells everything at double MSRP or more. I can buy straight sections but my mandrel bender is only good to 1.5" diameter. Mainly used to make hydraulic lines, fuel lines, or brake lines.
