white smoke after oil, plug/wire change

[MattB]

Hey guys,

First let me start by saying I just took the car out for the first time yesterday since November as it was sitting all winter. Drove the car an hour and a half home and it ran perfect the whole way. I changed the oil, new plugs (NGK BKR7E's gapped to .028), and new NGK wires. I also replaced my old speedo cable. First thing I notice is it has a low idle and a misfire. I take it for a spin and it runs fine, besides the misfire at idle. Next thing I know I've got white smoke coming through the dash. I take it back home and it looks like the smoke was coming from the exhaust manifold. It was late at this point so I let it sit and haven't touched it since. I assume the misfire has to do with the plugs/wires, but I'm more worried about the smoke at this point. Any ideas what it could be?

Could be a pin hole on one of the coolant hoses and there could be oil in the valley

Dunno what the "white smoke coming through the dash" deal is about but thought I'd point out you should change oil before putting a vehicle up for storage not after.

May be unrelated as mine came through my Exhaust tip.

But awhile back i changed my plugs and wires to the same exact one's you are using and the same day my car started smoking under hard vacuum slow downs. Everyone assured me that plugs could not cause this so i started looking else where.

Well the smoking is gone or well at the very least a lot less noticeable now.

Also about 3weeks ago i for the first time in a long time changed the plugs on the 92 All Trac (205/3sgte) and the car started smoking just like the Supra.

Only thing i have found similar is that both cars where being switched to a colder plug and smaller gap.

Also the smoke i had experienced was Light Grey (OIL)

^^ that's weird you should say that, I went to a colder heat range and smaller gap, just took it for a drive and it wasn't smoking but I went a pretty short distance so we'll see.

--Noted on the oil before storage...I had actually changed it like a month or two before but still.
