please youtube-- hpim3853.avi -- for WTF

[lfausty]

YOU TUBE VIDEO DELETED !!!!!! THANKS EVERYONE




for three minutes not taped started car ran typical awesome started the surging - exhaust smoke cleared - and video ran from there at 5 or so minutes where noise comes in, after getting in car reving a bit to see if idle would stablize, driving first and reverse 20-30 ft back forth couple times and the idle stablized but low -- parked and running got back out and in listening more til video ends at 6-7 mins.

IT IS -15 DEGRESS DONT KNOW IF IM HAVING A WINTER ISSUE OR JUST TIME UP FOR SOMETHING TO CRAP OUT ON ME.


Heres what doing see if any change,
1.alt belt is shot so replacing it
2. tstat replacing stant with orings 632 627 but having issue with oring staying on tstat side (loctite to tstat) and other oring seated , bolting together its really thick 82us sure all these parts go in? its really thick, as compared to the gasket type that were on orig tstat(germany). ANYWAY LEFT/ BOTTOM BOLT ON THE HOUSING *UCKER SNAPPED. OMG drilled and tappd a abit to get a bite tip broke off now and now cant drill that material. fit a nut over broke bolt, barely , and going to weld inside nut to bolt and try.

[Barbapapa]

just a guess-i think its a vacuum leak causing both the funky idle and the wtf noise

about the tmst, r u shure u the old oring isnt messed up? the one deep inside that has a metal sleeve.

[Mrmerlin]

Lisa, if you can get a copy of the PET and look up your T stat housing and the partts that go in it .
I am not sure your car has the inner Sealing ring,
it would be good for you to post a line about the year of your car.
The outer O ring that seals against the T stat is fatter and should hold the T stat in place, but if not then using some silicone for the edge of the Tstat and then the O ring should work. As far as snapping off the bolt you might consider a new part from 928 International its a half price for a used water bridge

She sneaks the car info to all of her text, one way or another.

[Fredfox]

sounds like the fan clutch or electric fan to me. Is the fan coming on and off when the noise starts?

My money is on vacuum leak.

[lfausty]

tech944 i do sneak it in cause everyone says post and i cant go back when first signed up and add that line -- ill try again but i just keep on keepin on with each post uhh uhh uhh 82us

heres pic of tstat inner seal its right there in pic just above bottom bolt put the seal against that lip- yes? and other thicker ring over top of tstat -- i put all pieces on tstat with loctite and will assemble as unit. there the older gaskets now cause my brand new ones got muched s*cks. well the top ring pic one did.

i prob have the 78euros parts car one -- but going to put nut over bolt weld inner nut and try.

[Barbapapa]

Sorry, the inner oring thing with the metal sleeve is from later cars.

are u sure 2 orings go there? i thought it was just one. could that phat second one be intended for the lower bridge where it goes into the block? Mmerlin?

good idea on welding something on that broken stud to remove it! the heat from welding may loosen it up too.

[lfausty]

shows the thinner around the hose end and thicker on the tst bolt in

welding failed and broke more of the screw

[Mrmerlin]

first only one O ring holds the T stat in the water bridge,
The Tstat will fit into the detent in the water bridge, then the O ring goes over top of it,
the thick O ring is for the base of the water bridge so leave it out,
the one you have pinched is the one that should be used to seal the Tstat, so you need another one.
You dont have to worry about the rear Tstat seal as you dont have one fitted to the bridge.
At this point if you can remove the tap/bolt from the broken part then I would order a used waterbridge From 928Intl.

[Mrmerlin]

actually looking at the seals again......
the one thats on the front of the Tstat or thats glued to the bottom side in the picture is the correct one to use for the Tstat seal

[lfausty]

yeah the one i have pinched was new to replace rather have new seal too ( there wasnt a prob with tstat uhh there is now) well glued the old gasket to new tstat for now , will take off top unneeded ring.
I HAVE TWO USED STATS TESTED GOOD , IT WAS GETTING A NEW SEAL (SO BOUGHT ANOTHER WHOLE NEW ONE) HAVE ALL THE ENG PARTS FROM 78EURO PARTS CAR, IF CANT GET BOLT OUT, will get the 78s water bridge, like thatll come out, try to do it all in timely fashion so if all fails can still make 928intl sale if need to. thanks

-- had bought a tstat months ago when had warm-up to op temp stalls out (it was vac leak) issue and never put in , what the hell was i thinking to install now er

cold freezing out is causing trouble -- you saw video -- but still the cools cool and hots hot at rad all flow real good nothing even remotely given me trouble , sucks. Ill need more coolant now too.

switch it all now and do belt /s new and see if surge and noise goes, check to see if something went brittle cold vac leak, fix


my sleigh aint gonna be ready for christmas if i keep this up , lol

[MPDano]

This vid does sound like vac leak or maybe one of the Air Valves isn't functioning correctly. Have you tried plugging both lines going to your valve hanging off the crossbar? Do these EFI models have an AAV on them?

[MPDano]

Oh God, that bearing noise sounds scary towards the end of your vid. Water Pump?

[lfausty]

yeah just what i was thinking WHAT? english p lease -- no i get it,mmhmm-- ill check crossmember bar valve if plug both lines it will do what - run without surging or you trying to snuff me out permanately.

woops posted up and you posting too. 2 ^ and 1^ no joke me scared to -- i was hoping youd chime in dano and the sound may be familiar to clutch fan (lubing) prob and id follow ur proced.

[vdubr928]

Fan clutch doesn't have much to do at idle. Fan clutch will work harder when you rev it. That is when it would be more likely to make noise.

Just from listening. Definatly a bearing on the front. Here is where I would start.

Check all the accessories frist. (a/c, power steering, Alternator, ac clutch) Remove belts and spin. Listen for that metal to metal sound and check for rolling resistance. Also check the bearing that supports the fan. If you think you find the culprit ditch that belt and run for a few minutes and see if it's gone. (watch temp closly if fan belt.... new t-stat so, should be ok for long enough to verify the noise is gone)

If not there then you have a bigger problem. Let us know.

[lfausty]

update the bolt with ezbit still broke in bolt hole (machine shop monday)
the bridge from 78euro a fit but no temp switch at top so wont work
the bridge back left bolt broke and the right front bolt,too , cause there angled the bridge is pinned, DRILLING IS THE ANSWER, in this case. Drilled and tapped right front, was enough to slide out and the backed left side out with double nutted over the bolt and it did come out.

so flange gasket and oring and coolant new and will put back together.

MIND YOU A TOTALLING UNNECCESSARY JOB turned into hrs and hrs and a day to machined ezbit out.

and still to do the alt belt

so mb not registered i run over town hall 200.00bucks thursday, take the battery that was out ( in 67 912 is using/testing with it) put that back in. So good to go. The radio lost its code , so i code it, and i have bit loose ign, it gets turned off but not quit, battery dies. I disconnect battery put charger on it, charged reconnect battery and the car locks down, keys on seat. disconnect and try reconnect now my 300e (92 mind you, noone would steal) thinks its being broken in to so alarm goes off. I had to coat hanger break into, get the key .
Key from the outside, lock and unlock door, disarm it. and reconnect bat.

Moral of the story Dont Wish Me A Merry Christmas, I dont buy it, for a second LOL.

worse of all im sure its not over Happy New Year , OMG are you kidding.
I CANT TAKE IT SOME MORE!!!!!!!!!! LOL

[Danglerb]

You survived, Merry Christmas.

[lfausty]

Ten buck machine job turned into 50 but did get the ezbit out non the less. Heres the job, bored out , insert, threaded again. Now for my next trick. You see im on the east coast which in my book means those that are my saviors here are 3 hrs behind in time which gives me many hrs to screw up. LOL Big thanks

[lfausty]

got all reinstalled and running - still need belt tighten and the alt replaced

start 5mins 950idle -- then surge begins 1100-950 up down -- 2 mins rev car stablizes -- car running about 10 mins now but at low idle 650 , i wouldnt exactely say running strong but good.
idle screw does nothing dont really want it to cause something else must be going on as idle was set 950 and running strong.
one other point the fan is running the whole time soon as car turns on fan never shuts off.(maybe it always does but i didnt think so.) fan does not move ANY direction good and tight,quite.

**scary noise that was in vid at bout 5 minutes into video is gone.

tstat opens at 185 closes at 125 (old one 170,100) took off those glued rings from tstat,cleaned up put just one ,a new one on it, installed the thicker one
on bridge while was out , since i had it to put on. Refilled coolant - with two 50/50 coolant jugs.
