probably a boost/vacuum leak... are you sure you tightened everything up good enough? how's the ilde? a little high?

[92rs25th]

Nope , it itdles at 1 K constantly.
I also did up some red silicone hose kit under the hood so I think I will go back through today on all the stuff I did and make sure everything is cramed on as far as it can go and tight as shit. I was thinking a leak somewhere but it seemed unlikely cause I know I put everything back on tight O.o will do though.

Going to try and track down my Speedometer problem again today. Oh , Does anyone make chips for the z31 prom ?

[ExTrEmEDrIfT]

yah if you check out http://www.jimwoldtechnologies.com they sell chips and computers and many other various things for the z31..


is this problem when you first start your car in the morning or the day or is it completely intermittent or all the time???

did you check out the speedometer cable to see if it was cracked or loose track it all out and follow it inspecting it very carefully because that is most likely your problem maybe youll get lucky and its just loose..

[92rs25th]

Eh , it just happened today but I think I found it , the part that conjoins with the turbo intake flange is like loose so I tightened that up , haven't started it yet.

[ExTrEmEDrIfT]

taht will doit a vacuum leak ..

i needa tighten mine uop but dayumn its hrd ta get to the nut on the bottom the the pipe its not exactly easy to get to but idk ill get to it when i go out to my car tomorrow

[92rs25th]

I just pulled the black thing off that connects to the turbo and peeled it's tightenening screw / strap off from it's tack weld and then put it back on , that way a philips screw driver can be put in there in various angles to tighten it up while being able to move the tensioner around.

[92rs25th]

Gawd damn it -_- I have a friggin tick now , wtf.
I felt the valve covers , no vibration from them , It sounds like it's coming from the center of the intake manifold which is weird. I tried to check my oil and she has F on oil , I even drained a cup and threw a fresh quart in and still ticks like a bitch. I also noticed , when cold start , My oil Psi won't go past 30 and under normal operating temps , about 150 - 160 ish , then oil psi is around 20 ish. Could this be the oil sending unit problem earlier spoken of ?

ahhhh no bad you over revved didnt you its bottom end bearings why us why now i just replaced my headgasket and think mayo cloged my port maybe i just overrevved it
better go get some bearings and dont drive it
where are you from anyway????
im from ny and gotta change mine or replace the engine (na under boost sounds fun) but first i gotta find the motor in the junk yard so hopefully there is one
but the reason i asy that is it will cost me more for the gasket set alone than the motor out the yard and i already got the cam seals so i can change them (cams that is) the turbo cams are higher lift and longer duration right

word of advice put the valve on before swapping so you know that you dont over boost first run and end up killing your turbo and fresh motor just tune it before even if its right before and hell id use it for a nuclear meltdown of the engine j
just get it set then block the hose off and take it out lol nuked
no dont relly when the throttle slammes shut it would end up
damaging the impellar
but tune before you drop you fresh one in
good luck

[stephenp]

actually you can take your screw type boost controller and place it in car just need extra vaccum

also the gauge idea sounds great (hmm i got the oil pressure and h2o temp where the radio was and my a\f where the digi dash used to be lol
and it turns out it is the poiwer sending unit
and the red hoses under hood do look sweet or atleast mine do
i also painted alot of stuff during head gasket lol like a yellow upper intake plenum green lower plenum green intake tube red idle air thingys and a green throttle bodie s
sounds stupid but looks awsome as shit
oh yeah and blue timing belt covers left the thick red valve covers thick and red though

[stephenp]

the oil pressue is the whole wore out bearing thing or atleast thats what im told by a good car guy that gives me alot of advice
until you ad in turbo then he says go find someone else to bother or drop a fod 302 in it i laugh and poke fun at how ill smoke his mouseterd anyday (and its even better now that i got a blown motor and tell him hey i can still smoke yoiu (knowing i have not a chance with the bearing impairment

well i guess im done harrassing the posts and stuff oh well good luck

[92rs25th]

Uhh..I didn't really make any sense of what your saying but I fixed my tick. The oil was way too thin to sufficently lubricate the lifters and what not. Tick gone after changing oil , filter , plugs and adding some quaker state hd 40 heavy duty oil too it , Oh , the oil guage seems to work now too O.o

well i dont have a boost gauge so i cant install it i dont wanna overboost it when trying to set boost so boost gauge is first and i was gunna install it after i rebuilt whole engine and broke it in..

[stephenp]

ok just let it be sloppy as in not much pressure at first as to noty cause the slamming of the impellers as i stated before

---O
-7 | 0 | 7+ , O = where needle stays.

it goes to 0 for the simple fact of no vaccumm or boost,
and the reason it goes to -4 when idleing its because the fact of the vaccumm, but not gaining boost hmmm, broken hose or perhaps a bad sensor .... no telling good luck (telling only i dont know the proceedure, other than spray all hoses with carb cleaner and see if there is a change in engine sound and other than that you may even have a faulty wastegate to many options good luck)
