tgv valve number 1 removal

hey my tgv sensor on my 04 wrx number one right in front of my turbo has a crack in it and is throwing me a tgv number one closed code and making the car run like ass. the soobie dealer said to order a new one i need the part number so im guessing it has to be removed. does the intake manifold have to come off to get to it or can you snake it out? ha anyone for some weird reason have one laying around and have a part number for it? also any idea how much one runs?

thanks!

If you dont mind rough cold starts, why not just remove the TGV's all together ? less restriction = better flow $$. I'm about to do this on my wrx, I just threw the p1097 code for the first time on tuesday, havnt seen it since then but it gives me something to do. Sorry I dont know the part number or price =/

yeah i was thinking about putting deletes in for 200 plus shipping, it would probably be alot cheaper. but i would need a tune (i think) and thats another 400 bills ha.. yeah it goes into a limp mode then after a while it gets a little bit better and boost comes back and then goes into limp mode and i turn it off and on so the boost comes back but still runs like ass. i just took my vta bov off and put the stock one back on. maybe it will help with the car not running so great. but thanks for the suggestion! is the deletes a pain to put on??

You don't need a retune for TGV deletes. They just have to defeat the CEL's.

you said i dont need a retune. does that mean i dont need a tune at all because i have never had a tune before. so would i still need one after i put them in? ( i want to get a tune any way but it would be easier just to put them in asap.

Do yu have any type of EM now or not? If you dont it would be good to get a tune so they could then turn all the CELs off that deal with the TGVs.

I see. If you got the cash and time, do the TGV delete, and then take it for a nice tune.

The IM DOES need to come out to do the TGV's..... My advice to you would be to get the phenolic spacers and get it all done at once. It is a BIG PITA to do... and you really only want to do it once. To take the IM and TGV's out, you are looking at an 8 hr job in and out.

Alright yeah that does sound like the best way to go and might as well do the plug while im there. can you point me in the right direction in what deletes/spacers/and plugs to get? i was on grimmspeed and found the spacers and deletes..

GrimmSpeed
Do i need the Ceramic Thermal Coating, IM to TGV gasket, and the TGV to engine gasket?

If you get the phenolic spacers, get the OEM gaskets as well. If GS is doing your PnP, get their spacers as they mate up to what they do.

As far as which coating to get... What are you going to be doing in the car ? Auto-X, drag, etc.....

I personally wouldn't do it... unless you can weld well and all that. Are you wanting to learn ? I would try it on a UP or something similar .... Just a thought. Is it worth the 180.00 from GS.... probably..... Ask Ron (dumdum) here if he will do it for you for a bit cheaper.
