Mike B Posted August 14, 2008 Share Posted August 14, 2008 I had a failure of my Apexi EGT guage... thought it was something electrical in the sensor, but took it out yesterday as I was in there sealing the oil feed.. Guess what? Half of it is missing. I just dread looking inside the turbine. Car still drives fine, but the spool *may* be a bit slower... hard to tell. If I have the heart I'll take the dp off this weekend and have a look. can you believe it...? sensor never saw over 870 degrees. I have so many bad experiences with aftermarket parts. The only things that fail on my car are non toyota items. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted August 14, 2008 Share Posted August 14, 2008 Its one thing after another all the time I know how you feel, hope the Tubby is ok Quote Link to comment Share on other sites More sharing options...
MarkR Posted August 14, 2008 Share Posted August 14, 2008 Sorry to hear it mate. Fingers crossed the T67 is okay...... Quote Link to comment Share on other sites More sharing options...
Mike B Posted August 14, 2008 Author Share Posted August 14, 2008 hopefully it's shocking construction means the blades chopped it up when it was good and hot, or even better it went out the wastegate... still... ever had the feeling it's one step forward, two steps back?

Alex Posted August 14, 2008 Share Posted August 14, 2008 Feel for you, but on the brighter side if there is any damage it shouldn't be too bad as you've not noticed anything really yet (perf wise). Quote Link to comment Share on other sites More sharing options...

True... and it does pull well still in top gears at low revs, yet I'm a perfectionist, and knowing it's there will be enough to know I want it sorted! thank feck I didn't buy the to4z... lol then I would be crying!!!!

b_have Posted August 14, 2008 Share Posted August 14, 2008 Did you inspect it before you fitted the 67? Maybe that killed the gt40? Quote Link to comment Share on other sites More sharing options...
johnd-mkiv Posted August 14, 2008 Share Posted August 14, 2008 being on the down pipe would it not have blown it down the exhaust if it did break off and not come in contact with the turbo? Quote Link to comment Share on other sites More sharing options...
Pig Posted August 14, 2008 Share Posted August 14, 2008 Wow, never heard of a T67 going without abuse. Prehaps like john said it was the old tubbie that did the majority of the damage. Fingers crossed for you. Quote Link to comment Share on other sites More sharing options...
Marty Posted August 14, 2008 Share Posted August 14, 2008 I feel your pain. My turbo isn't so great either, but i have never noticed any performace drop, not boosting at later revs etc, it only see's 1.1bar and 1% wot. So with mine i can only assume it was like that when it was put on, last june!! Hope yours isn't as bad as you think it is, or like others say, the majority of damage was already there from the gt4088 Quote Link to comment Share on other sites More sharing options...
lockys96 Posted August 14, 2008 Share Posted August 14, 2008 but even though the manifold is prob the safest place to set the sensor for an accurate reading, i have mine mounted in the exhaust housing so this is one thing i have less to worry about Quote Link to comment Share on other sites More sharing options...

Fingers crossed for you. An EGT probe going through it does constitute abuse it wasn't designed for. Quote Link to comment Share on other sites More sharing options...

I had forgotten that the probe was before the turbo as mine is after. I thought prehaps the GT4088 had killed the probe. Quote Link to comment Share on other sites More sharing options...

Mike B Posted August 14, 2008 Author Share Posted August 14, 2008 cheers guys... Probe was whole when I fitted the T67, it's definately gone through this tubby. GT4088R ate itself, which is a noval trick! My mind maybe playing games but I can feel less midrange. anyone care to take a wager what it looks like when it comes off? lol To be fair, if it's been playing thunderball with the egt probe then it's done well to be still running! At least I will only be buying a core this time.. if it can't be rebuilt... the rate I am going I need a tubby with 5 spare turbine wheels. ; All joking aside, if they were bolt on I would save myself a lot of money.... why don't they make then I wonder?

Muffleman Posted August 14, 2008 Share Posted August 14, 2008 Fingers crossed for you Mike ! I have so many bad experiences with aftermarket parts. The only things that fail on my car are non toyota items. Amen to that, couldn't agree more Quote Link to comment Share on other sites More sharing options...
johnd-mkiv Posted August 14, 2008 Share Posted August 14, 2008 sorry think ive read it wrong, is the egt sensor attached to the manifold or the downpipe? Quote Link to comment Share on other sites More sharing options...
Homer Posted August 14, 2008 Share Posted August 14, 2008 Fingers crossed it's just gone through the wastegate, but if there is a difference in spool/power it's not a positive sign What a nightmare you're having with this Mike. I still never understood the argument for mounting the EGT sensor in the runner rather than the collector/wastegate tube (where it can do no turbo damage if it fails). EGT's are only going to be at an area you need to look at while under full boost, i.e. when the wastegate is fully open and exhaust gases passing over it...

EGT's are only going to be at an area you need to look at while under full boost, i.e. when the wastegate is fully open and exhaust gases passing over it... that's a good point! although it's nice to see the guage working under constant gas flow, but in retrospect I agree Quote Link to comment Share on other sites More sharing options...
Mike B Posted August 15, 2008 Author Share Posted August 15, 2008 I am a very lucky boy!!!!! Uncoupled the downpipe and took a peep around the corner with a piece of broken mirror and a torch… There is the turbine…. Had a shift around can see all the blades, so I start turning them one by one…. All perfect!!! Woo hoo! Looking at runner no 6 it’s virtually opposite one of the two pipes that feed the wastegate, so the probe has gone out of the gate. I’m surprised it went through without jamming it open… it’s functionally fine from what I can tell. Dodged that one…. Now for a new decent probe… Quote Link to comment Share on other sites More sharing options...
