So heres whats all to my Del Sol

:D16Z6 Vtec
:Lsd 5speed Transmission
:Skunk2 Intake
:TD05 16G Turbo
:Intercooled

So heres my problem: Recently my catch can is smoking excessivley. When it was first setup it smoked a bit, more of a vapor smoke, but now its smoking way badd.
Heres a picture of what its doing.


Ive been told pcv- dont think its that
Ive been told to vent my crankcase- Hints Catch can setup
Ive been told Ringland- Hoping its not that

Any help would be greatful fellas.

As I told you and everyone else did. Do a compression and leakdown test. I'm still gonna guess cracked ringland

Nate Case

Should i replace the pistons and all that or just go with bseries? seem like they can hold more abuse.

Do the compression test and come back and post the numbers here. Also if any of the numbers look low add oil to the cylinder and re test

1. Is it a drain back Catch can?

2. If so are you sure the drain isn't kinked?

3. If not have you drained the catch can?

4. Is this picture taken:
- At Idle
- At high RPM
- With the car cold
- With the car hot

5. Is it constantly/steadily smoking? Or does it get dramatically worse when driving the car? Worse in vacuum or boost?

Nate Case

Catch can drains into back of the block-

Im sure its not kinked, i took the can out drained it, cleaned it. put it back in.

I took the 2 hoses off the valve cover and started it up, and the smoke comes from the ports in the valve cover. its is definately internal problem.

Its smoking worse and worse, low oil pressure, boost takes along time to build up.

motor is toast. who tuned it?

I bet you had a boost spike from that manifold and damaged a few pistons.

Nate Case

Finally got pistons pulled..
Im going to replace with all new pistons bearings gaskets.
Probably use stock rods and low compression pistons.

Im just going to run into a problem when it comes back to timing...
Anybody got a good run through of how to set the timing on this d16?

What did the pistons look like?cracked ringlands? And search there's plenty write ups on timing

Nate Case

ill take more pictures. they look burnt. one piston looks really clean, the other three are toasty. The rings looks good still though. i think the problem may be within the valves in the head. Taken it to get hot tanked and rebuilt.

So no cracked ringlands? The ringlands aren't the actual rings themselves its the part of the piston in between where the rings sit

Nate Case

i see no cracks in them. i have a rough spot within my 3rd cylinder though. kinda looks like a spider crack. idk if that may the problem or not. Honer may take it out..

have any opinions on these pistons?

Those pistons are good. Pic of cylinder wall? Dont know how it could get a spider crack

Nate Case

it may not be a crack..but it you slide your finger nail around it my finger nail catches on it.. Ibet once its honed out itll be gone

Nate Case

Ok, after going back looking at the pistons...
Man you know your stuff...

Ringlands are cracked and just falling apart.....

Lol there it is! I figured that's what your problem was, same thing happend to me

rclark

Ouch, that's ugly.

Nate Case

welp, low compression pistons on the way and block honed. thing should run pretty decent once put back together: )

Painting those AN fittings was not a good idea.
