I recently did some non major work to the old girl
added a secondary coolant temp gauge - I don't have a heater box I put a steel plate where it used to be and had been happily running with no issues by just putting the open heater valve between the two existing hoses that were already there. I removed the heater valve and put a 19MM adapter for the temp sender in its place. Seems trivial and logically should be the same as the coolant passing through the open valve.
oil pressure gauge - I added this to an existing sandwich plate on the filter that I have been using with no issues for oil temp
oil catch can - I've just been running hose down to the ground for years, thought I'd clean the back of trans and the environment up a little.
been using air filters on my dual webers for years for safety from debris etc, I switched back to velocity stacks I had cause filters were looking sad.
When I fired the car up to test the gauges I got it up to temp and it started blowing white smoke and smelled pretty strong it hung around pretty thick for a while.
I am wondering how the heck doing what I did can now cause exhaust smoke at idle and acceleration. I checked the brake booster and it does have some fluid in it, I removed the vacuum hose and plugged it. Still smokes, maybe a little less, maybe it's in my head and I don't want to run it too much if I coincidentally have a coolant combustions issue.
I put the regular open hose back on the valve cover, thinking I don't think this would make a difference, but stranger things have happened with this car, trying to rule stuff out.
Do you think that freeing up the airflow moving from filters that have not been washed replaced in a long time to stacks could have created way more vacuum and sucked the brake fluid in to burn? if so how long would it take for it to stop smoking, I have tried to start it, bring it up to temp twice since noticing and once I give it some throttle and smoke comes out, I turn it off.
Could I have coincidentally had a gasket failure? no water in oil, no overheating, no coolant loss, but I know it could still be possible to burn coolant with out those signs. Any help is appreciated.
Also, if I decide to open up and replace gasket, can I use the standard MLS ones even though I am at maximum second overbore size. I can't remember what pistons size I bought, it was about 10years ago and I can't find receipt and didn't take notes, but I'm thinking it was 91 or 92mm IIRC. (writing this clicked something in my brain and I went to go check a place and found the receipt from machine shop from 2011 it was a 1.2mm bore so I guess 91mm pistons, but I remember them saying no more after this) regular m10 gasket, s14 gasket, regular MLS, s14 MLS, or do I need to have one made? I also can not remember what I did for gasket back in the day.
