Just to get some opinions my ls swap is smoking a lot of white smoke, the engine was upside down on my engine stand for a bit before it went in, and I'm just wondering do you guys think it's the head gasket? I pulled the plugs and they look normal, there is some oil on the piston. I know I have some leaky valve seals though. I also got a lot of chemical degreaser on my exhaust ports. The inside of my header is rusty too so I know some of that is burning too.

Side note my idle is shitty but I have no vac hose on my map sensor and I have no tps. Cleaned my iacv while it was out. Are those two things causing my idle to be at 2000?

 

How long have you had it running?

 

Jesus christ dude, what the ****.

First off: Oil on the pistons is BAD.

Leaky valve seals are BAD.

Your map sensors needs a vac hose to it, and how dont you have a tps or iacv? Thats whats causing your high retarded idle time bro.

 

Check if you running low on coolant and Is there water or coolant leaking out of the exhaust, also check the dipstick and see if it is milkly

 

First off, bro, click the sig, you act like I have the cash around to get new valve seals or a head. I make the best of what I have and will get around to it soon, I just simply wanted to know if valve seals leaking would cause it to smoke like that.

Still have no vac hose to my map and it runs and pulls strong, i dont have a tps and haven't had one on about three different cars and never could tell the difference. I do have a IACV turns out I had the car low on coolant, but never really ran it much either. My idle settled down perfect at 800.

Long story short, I DD it now it smokes some when I get on it, but have no hesistation or loss of MPG thats noticable and my idles perfect.

 

I would have posted this straight to the build thread. Then people would have background and the correct context to answer your question.

 

Noted, thought I would get faster response you can delete this now though
