zayd687 Member 74 Member For: 15y 1m 2d Posted 08/12/10 11:19 AM Share Posted 08/12/10 11:19 AM HI Guys,not sure if this is the right place to post but I have a major problem with my ford ba n/a.Anyway, we've been doing a conversion for a ford ba n/awe had completed the conversion, and only thing left was the dump pipe to be made up by the exhaust place.before the car had the exhaust it would start, and idle normal.the dump pipe was completed today ( the exhaust guy forgot to make a thread for the O2 sensor) so now I have a dump pipe madewith no thread to fit the O2 sensor.but the problem is the car when you start it within couple of minutes is chucking out white thick smoke.it pretty much can cover the street!!!im not sure what happened because the car was never driven at all!!. so here are what the possible problems I think it might be and need advice/soloutions if possible* O2 sensor was not connected and dump pipe was made without thread so I cant fit it on have to make one or something could that cause white smoke?* Turbo is sh*tted? and need to purchase a new turbo?* headgasket is screwed? how do I check this? car wasnt even driven???!?? just mostly idled.* boost leak? its really worrying me as this has really made me stress. it only started smoking once the dump pipe was on but the car was driven from exhaust shop maybe 2 metres down the road then it started smoking huge smounts of smoke. its white.any ideas guys?

Guest Slash Guests Posted 09/12/10 04:16 AM Share Posted 09/12/10 04:16 AM Engrish, learn to type it correctly Back to your problem... Turbo seals are fcuked & need replacing. If the turbo is secondhand, I'd recommend a full recondition. Link to comment Share on other sites More sharing options...

I would assume you tapped it into your sump, if so how did you tap it? are you sure your drain lines are big enough?I do believe replacing the seals is a rebuild, cause once you take the compressor wheel off to get to the seals you need to balance the shaft etc once the compressor wheels back on.I do believe you can kill the seals even with the car at idle, even at idle the turbo is spinning quite fast which in turn means the bearings are starting to heat up pretty much straight away, but not only heat if the drain is incorrect oil pressure will be building up as well, im sure someone will be on shortly to either back me up or give you their findings At this point I would recommend getting it towed to a mechanic, preferably one that knows turbo's and get them to check it, if something is wrong you dont want to risk any further damage!!! the last thing you want is for something to happen to the turbo and then let it shoot crap into your engine.good luck with it all mate, let us know how you go Edited 09/12/10 04:37 AM by Rusty XR6T Link to comment Share on other sites More sharing options...
Guest Slash Guests Posted 09/12/10 04:49 AM Share Posted 09/12/10 04:49 AM Best thing to do is jump in, select 'D' on the shifter, left foot on brake, right foot on accellerator... Buuurrrnnnooouuuttt!!! Link to comment Share on other sites More sharing options...
