Re: TB removal and then some!!!
Carter,
Another PM answered..... Quote:
Just going to take my time and get this idle issue fixed. A learning experience for sure. Also will wait and see what the results are with mine before thinking about sending the TB out to Marc for a check-up. Glad you enjoy the pics, I enjoy taking them!!! Keep us posted on your progress too... Quote:
I guess my concerns are winter driving, (which I don't use the Z that much), so not a concern....lol The other one is air being trapped in the system....and I assume your bleeder valve would solve that problem. I know there are a lot of members to have done the bypass in different ways, so it is something to be considered.

Re: TB removal and then some!!!
Tom,
Here's one way to eliminate coolant flow. Different than mine. https://www.corvetteforum.com/forums...post1581460754 You might also ask Marc for the "helper spring" he sells for the TB. That may be enough in your situation.

Re: TB removal and then some!!!
Dennis, I'm already in this far, so the plenum will come off. Then will check for vacuum leaks and see if any hoses popped off.
TB is last resort..... Sent from my SM-G935P using ZR-1 Net Registry mobile app

Re: TB removal and then some!!!
Latest update.....success!!!!
After I used my 5 lb sledge and crow bar, removal was easy peasy....lol Having a cold one in celebration of my first plenum pull myself.....woohoo!!! Used a hand siphon for the antifreeze, what a treat that was....I won't go into detail and yes it makes for the case to do the TB coolant bypass.... Just looking at everything at a quick glance, all seems fine. The one thing I was concerned about was when I pulled the plenum up the "curly" line (I imagine a PCV line) came out of its connector. But I can't tell you if it was already out or not. Will check more within the net few days. A lot going on, even with the 74, can't loose sight of that project... All-in-all, everything went well so far!!! Looks like I'll continue to freshen up parts as time goes on. Now is a good time to repaint the plenum. And maybe even more.... Here are some pics and a question or two..... Another "famous" block(s) of wood....lol...they come in handy!!! You may be able to see some of the connectors that need to be undone before plenum removal....the crow bar really comes in handy here....I didn't really say that, did I??? just kidding, must be the brew..... IIRC, there must be 5-6 connections that need to be unplugged and one unbolted. Take your time when doing these, as patience is a must... Again, directed to those who may want to attempt this for the first time...

Re: TB removal and then some!!!
One of the also "famous" curly lines under the plenum. This one came out of its connector when I pulled up on the plenum. Did it pop out before, that I can't tell you.....
I imagine this is the PCV "pig tail" that Yun has referred too on numerous occasions. Have to see if this can be replaced, just to be sure.... not tapped.... tapped, no foreign objects allowed here.... had enough for the night....lol the LT5 is feeling nice and cozy all covered...

Re: TB removal and then some!!!
Looks like the old original plenum gaskets were re-used when the plenum was pulled last. I'm not a fan of re-using gaskets, they're not that expensive compared to the problem of chasing vacuum leaks.

Do you carry the part where the hoses connect into??? the bottom hole in the connector is the "curly" line connected to the LSF of the plenum.
