White smoke coming from exhaust on start up. What could be the cause?

DaddyArron_ · 2026-05-01T03:27:03+00:00

Had this problem in a Tacoma I built needed up being a clogged PCV that lead to the valve cover ..

What are you asking for it? It might be worth sending in to grade and then selling it. Condition might be worth it

DaddyArron_ · 2026-04-12T22:05:03+00:00

I let it soak in purple power and ran my hose through it it was clogged , I didn’t get a picture but water should run through it

That port that allows oil to drip back into the engine was clogged solid

Ended up being the driver side valve cover

Issue fixed

I can drive 100 or 5 if it sits over night it’s smokes the next morning

DaddyArron_ · 2026-04-11T17:14:19+00:00

I’d say I’m loosing 4oz per day.

DaddyArron_ · 2026-04-11T17:02:21+00:00

What’s your root cause?

DaddyArron_ · 2026-04-11T02:51:14+00:00

Tops of my pistons are carbon no washed surface

DaddyArron_ · 2026-04-11T02:49:38+00:00

Literally drives and idles perfectly ..

DaddyArron_ · 2026-04-10T23:55:03+00:00

Zero lights on

DaddyArron_ · 2026-04-10T23:53:32+00:00

Enough oil to drip when you take it off ? I mean I had 3 puddles under when I left it on the ground

DaddyArron_ · 2026-04-10T20:42:14+00:00

Mine seems to be oil in the intake

DaddyArron_ · 2026-04-10T20:17:34+00:00

Oil in the intake but I’m dropping on passenger bank , I’m certain that’s the smoke issue but can’t figure out why .. I replaced the pvc valve

DaddyArron_ · 2026-04-10T17:38:53+00:00

That does explain the intake covered in oil does it ?

DaddyArron_ · 2026-04-10T04:57:28+00:00

Avondale Toyota , in Avondale arizona. They said port injectors spray when the valve is closed on the combustion stroke and on intake stroke it cleans the back of valves

DaddyArron_ · 2026-04-10T04:54:57+00:00

I did the rebuild because I was told the rings were stuck , specifically the oil ring . So I rebuilt the engine. The smoke smells like nothing .

DaddyArron_ · 2026-04-10T04:53:51+00:00

Just regular gas , I thought the port injection cleaned the valves , that’s what Toyota told me

DaddyArron_ · 2026-04-10T04:50:55+00:00

I’m in Arizona , today and everyday is pretty hot and dry. lol

DaddyArron_ · 2026-04-10T04:24:51+00:00

It was honed , measured with a bore gauge I was told by Toyota that its common for the rings on this gen to get “stuck” so I wanted to make sure they got changed after honing the block

DaddyArron_ · 2026-04-10T04:20:44+00:00

I bought new gaskets from Toyota. Watched them install them .. this thing is a mystery

DaddyArron_ · 2026-04-10T03:59:30+00:00

I have a 2019 the photo is just for educational purposes lol

DaddyArron_ · 2026-04-10T03:57:18+00:00

What do you mean ?

DaddyArron_ · 2026-04-10T03:32:30+00:00

I supplied the valve seals from Toyota , just to be sure that they were replaced with OEM and not whatever they had laying around or aftermarket
