Seafoam question

[Chattzx]

So I'm about to seafoam the Z and I have about 8 feet of clear tubing and a "T" connector piece to distribute the liquid into each of the TB's, but my question is what is the easiest way to get the clear tubing into the TB area?

I have not done this but it seems like a reasonable method.

In the 2nd picture where is the line running to? Is it just crammed underneath the intake tubing?

I just took a picture let me put it up real quick to make sure its the right one

[Chattzx]

Driver side. Is it the one almost in the middle kinda angled to the left a little bit?


Passenger side is capped off?? I'm not sure why but it has a screw capping it off

Yes, those are them. Here they are in naked form:



The driver side comes straight out on mine, but on your's it's angled. The vac line on the passenger side would be capped for AIV removal, IIRC.

BTW, this whole thread is more of a technical question

Haha my bad buddy, I just needed a quick response and not as many people check the technical forum all that much so if a mod would like to transfer this thread over there feel free to do so haha. So I just need to pull those vacuum lines off and replace them with my setup? I really appreciate your help as always man.

I used the brake booster hose, past the check valve. Had quite the smoke show. Literally had people slowing down yelling for me to "Turn it off! You blew your head gasket!". Smoked for about 15 minutes.

Yea I used that line too. It's easier I think

But it doesn't feed the cylinders equally. This method gets equal SF to each bank.

No worries about the tech section. I check it quite often, as others do as well

[es.biggs]

The brake booster hose works great for cylinders 4 and 6, but with that method you aren't cleaning anything on the other bank or cylinder 2. I did it that way when I first got the car and after a while I read up on this more complicated way with both the TBs, and it seems like common sense - I didn't even think about it. Facepalm lol

EDIT - BigT beat me to it!

my 90 300zx had its engine rebuilt 30k ago and i just recently sea foamed it to see how much would come out. almost no smoke. shows that if u just take care and use synthetic oil and change every 3k that it will help keeping ur engine clean.

[andrewbueno92]

nvm now it triggered check engine with code 32 for egr :0

[Ace2cool]

Code 32 may just be the valve sticking. I have a CEL 100% of the time, haha. My EGR is gonna get deleted pretty soon though, so it will actually have a reason to throw me a CEL.
