I finally got my 2.3 running. The car's far from road-worthy, but at least the engine runs. It runs, idles, and revs, oh, and smokes horribly bad. It's all white smoke and since I don't have my downpipe on yet it's going everywhere, but I had someone check and it is comming from the exhaust. The block was honed, cylinder walls oiled, and new rings and bearings installed. It's been started and ran for maybe a total of 1 minute, through multiple cycles. I can't let it run too long because of how smokey the garage gets. I'm assuming that all the oil has burned off the walls, should it still smoke until the rings seat? First new engine in a while and the first one I blew a hole in side of the block because I put the rods in backwards . I know the pistons and rods went in right on this block, I just have an embedded fear of something happening. I'll get the exhaust on here shortly, then I can let it run a little longer and see if it clears it out. I don't have the cooling system hooked up yet so I don't want to let the block get warm and over heat.
Sounds like you are having the same problem that Dr.E was having with his car when he first started it. (Bad Turbo, needed to be rebuilt)
It shouldn't smoke much at all...white means water...headgasket or cracked head...unless it's actually not coming out of the exhaust...
There's no coolant in the block. I just started it up a few times to finally hear her run. My exhaust flange had some oil in it . I think it's because my oil return line has a bend in it, and/or is too small. I need to make another one that's a little straighter and bigger. What size should the line be?
I think the line should be At least 3/8" or AN-10 line, but im not for sure.. I would guess you are having the same problem i had, and you are pushing oil out of the turbo's Oil seals. When i first started mine it smoked so bad you couldnt see anything out the windshield (No exaust) Rebuilt the turbo and it Runs great... When mine was smoking i also thought it looked white, but it WAS oil.. but it wasnt actually burning, just being vaporized by the hot exaust. Dr.
I took the turbo apart and had a turbo shop look at the center section and shaft. The center section needs honed and the shaft ground. He said the guy who "rebuilt" it before probably just sandblasted everything to make it look rebuilt. But I got it from someone who got it from someone. Anyways, yeah, between the shaft play and small oil return line I had tons of oil in both the compressor housing and exhaust housing. I'm having the Diesel shop hone the center section 5/1000" over and get new bearings, and their sending the shaft to be regound and possibly ballanced to a shop in NY. I should get the shaft back in 2 weeks. I'm going to get an N/A exhaust manifold for now so I can tune this thing. There's no boost in idle so this shouldn't cause an issue.
if you havent already sent it somewhere, send it to evergreen turbo. The guy does good fast work, and the price is very nice. Comes back rebuilt, balanced, and looks like new. http://www.evergreenturbo.com/ Dr.
