I have a D16Z6 and if I drive the car WOT it starts to smoke around 4500 or as I'm engine break downhill. I know it's water from the coolant system.

I pulled the plugs after driving one day and white smoke was slowly coming out of cylinder #1.

My AFRs are around 13.5 in VAC and 12.5 in boost. Running 12lbs on a TD04 14G turbo. I just ordered a new dizzy because I have a random misfire at idle and the car will not go above 5k on occasion

I blew the headgasket over 6 months ago and installed ARPs when I replaced it. I did not have the block/head leveled.

Is there a chance the head/block is warped, the HG is blown, or could it be a cracked cylinder?

I don't want to pull the head to see if the cylinder is cracked because I don't want it to shift if I pull teh head and I don't want to blow $60 on a headgasket for a motor I'm about to pull anyway.

I'm just currious as to what you guys think could be the problem.

Thanks

Bump.

 

your rings on #1 are shot. or maybe the valves. does it drive the same?

No, it doesn't. I have a cylinder misfire and recently (last 2 weeks) I can't really take the car over 5k.

I was thinking it's the distributor causing that, so I got a new one (about to go put it on as I'm typing this).

Other than the mis at idle and it not going above 5k it's still relatively strong.

I never would have thought the rings would cause it to smoke white because white smoke means coolant/water.

Thanks for your input.

Do a leak Down test before you start taking it apart. that'll tell you exactly what's wrong.

 

I'm going to do a leakdown test tomorrow.

I know this is ghetto/band-aiding a problem, but I was thinking that if it turns out to be the rings I could always just swap a stock piston with rings from my spare motor into the #1 cylinder.

That way I'm only paying $50/60 for a new headgasket vs 150 for rings & a headgasket on a motor that only has to last me another month, two tops.

 

does your exhaust make a different sound. kind of sounds like a bumble bee, or that wrx sound? no dead serious that happened in my friends gsr when he blew his rings and snapped his belt. plus it drove like a slug

 

No, exhaust and everything else still sound the same.

With the new dizzy I can take the car above 5k (took it to 6k and then shifted just to see if I could.) Dizzy fixed that problem.

I'm going to try to get a leakdown test done tomorrow. If it turns out to be the #1 cyl rings I may switch the piston like I mentioned earlier. Just don't really want to spend the time pulling the head and pan just to throw in a piston.
