Message	As some of you might have read, I picked up this 91TT Last Tuesday. Last owner used 15W-50, and because it's colder I switched to 5W-30. (Changed myself, Nissan filter, Mobil 1, 3 5/8 qts) I noticed that my oil pressure varied more with engine speed. (as it should) So here's the boost part; At idle:low spd I see -12 boost on the stock gauge. (normal right) Well when I wind it out, it doesn't go passed 0, period. I imagine that since it should go up to 10lbs, I should be seeing higher than 0. Is it likely that the gauge is a lie? (much like the cake) Sorry, I looked around and didn't see anything exactly like this. (Even safety boost gets to 2 right?) Thanks in advance for the help, I really appreciate it.
Follow Ups	Sorry, but I have a question about boost. - CoHPhasor 04:46:57 04/03/10 not sure if I read that correctly, but sounds like you have - LJZTT 05:20:25 04/03/10 Definitely what I'm trying to figure out - CoHPhasor 05:24:09 04/03/10 lower than that actually, but the OEM gauge is "approximate" - LJZTT 05:50:57 04/03/10 interesting. Either I'm -12:0, I'm higher and it's lying, or - CoHPhasor 05:56:54 04/03/10 what I am trying to say is dont worry about the numeric - LJZTT 11:31:09 04/03/10 Sounds like a seized turbo. - Draker (Eugene, OR) 15:02:11 04/03/10 An easy gauge check - ConVerTT 11:02:59 04/03/10 My test gauge was $15 from Pepboys. - Woody75 (Denver) 12:07:39 04/06/10 I'd pull the down pipes off and check for a seized turbo. - Wright (Ca) 09:50:39 04/03/10 if the boost leak is THAT big, the car wont rev much past 3k - LJZTT 11:33:55 04/03/10 Have you ever owned or been in a z before? - pearlzed(toronto) 10:27:44 04/03/10 I was out today, but will look deeper. May need an SF Z'er. - CoHPhasor 01:55:39 04/04/10 Ok, finally got to check it out, - CoHPhasor 04:45:10 04/07/10 Still sounds like a bad/frozen turbo. - Woody75 (Denver) 07:35:01 04/07/10 That stinks. So pull the pipes to gain access to them? - CoHPhasor 11:59:04 04/07/10
