All you did was head gasket ?

Pull plugs pour some transmission fluid in each cly... crank motor over let it coat the cly walls... You might have dry cly...

also a hose with a small cut will sound like a bird chirping... acts like a musical instrument reed

also pull all the belts off... and run...

Pin point the noise...

p/s: also a transmission funnle... them long ones.. stick the small end in ear :} makes good listning device

suprakid91 09-23-2008 08:31 PM

yes all i did was the head gasket. i am positive i put everything back in the right spot. i only have one small bolt that is left and i dont know where it goes. i also dont think that bolt that is missing is making any difference. i am going to try a copper pipe to listen to the engine. my car also doesnt idle. at all. it just dies whenever i take my foot off the gas. so maybe the whistle and the no idle have something in common? im stumped. i wanna get it running by thursday.

not idling sounds like a vacuum issue. (when combined with your whistle) Therefore, you have to look at what lines go into the intake system. (that would be my first guess).

Here is where it starts:
MK3 TSRM On-Line

Naturally.. again.. your down to hunting hose by hose...

suprakid91 09-26-2008 03:06 AM

things just add upp... i finally got a timing light and now the bulb is burn out. but the light is from 1988.... so i can only expect it i guess. oh well. ill just keep lookin or i will break down and buy one. i still haven't found any hoses that are worn or cracked or have holes. im stumped. this cars just keep throwin curve balls.

Grandavi 09-26-2008 06:17 AM

Well.. dont lose hope. The beauty of the car is that its mechanical (for the most part.. lol). So, therefore... a leads to b which in turn leads to c etc...

When you get stumped, you got 2 choices... (imo), ask a professional/expert or... start at a... then go to b... etc...

In the end, its usually forehead smacking time in most cases as it turns out to be that "obvious" thing that just slipped by. Me? Im old... I do the professional/expert route. My time is just to valuable. or.. worse case scenario... just remove everything you just put back on.. and do it very carefully, checking each part and step. Lots of work perhaps.. but if you cant find it any other way, it may be your only choice.
(again.. Im not a mechanic.. I just work on my car)

yeah. i hear ya grand. i think im gunna bite the bullet and take her in. i need her done because my other car gets about 7 miles to the gallon. (90 caprice with absolutly no exhaust... come right out of the manifolds with about 3 feet of pipe, and a bad fuel pump that i dont wanna spend any time or money to fix)

Im lucky, I have owned this 1988 Cresseda for about 9 years now and let it sit for 3 years (resulting in extensive rust). Its a true Toyota though... runs always. Thats my winter car and driver when I take apart the Supra. (about same fuel mileage as the supra... should probably by a Corolla as a winter beater :) )

suprakid91 09-27-2008 05:23 PM

well i didnt get the car finnished in time. but i am heading down to hot import nights tonight. im riding a 437rwhp 240sx. so that should be fun. i will tell you guys how it goes and if i get any more news on the supra. its really lookin grim. :(

suprakid91 09-30-2008 03:10 AM

so hot import nights was the SHIT. (sorry) i can not find any other words to describe it. moderators please dont clean it up. :x: but anyways, it was awesome. i havent ever been to an import car show that large and with that many cute almost naked Asian girls. haha. the 240 was quick but i hopped in a STI (that was also very heavily modded and very fast) in minneapolis. in the parking ramps we made 12 car alarms go off cuz both had really loud exhaust systems. it was really funny...


on a supra note... i started it up tonight with pretty much no problems except the dang tensioner squeeling like a pig. no little tea pot whistle or anything. idled for a bit and i reved it up to about 3000 and it sounded nice. no missing or backfires... so im pretty happy about that. i think i found the spot where the cam sensor should be placed so its tightened down now. i will report back if i can test drive it withing the next day.

till then, ill be on after school tomorrow! ha

Grandavi 09-30-2008 10:05 AM

So... any idea what the sound was coming from? It sounds like you got everything running finally, but haven't heard what the whistle issue was or if you fixed that.

suprakid91 09-30-2008 11:52 AM

yeah. i think i found what it was. i had the charger on the old battery. the charger was on a 50 amp start, so it was getting a lota juice. one of my friends told me it was probably my alternator trying to make up for the added power going to the battery. so when i took off the charger for a few days and started it up last night, no whistle. :nuts:

Grandavi 09-30-2008 05:23 PM

lol.. odd : )

suprakid91 10-07-2008 11:57 AM

disappointing night.
 
ok. i started it up last night cause i finally got my timing right and found the damn whistle. it was a vac leak.... haha. but anyways, i took it out for a nice slow spin around the block and as i take a corner gave it a little gas (maybe 3000 rpm) it starts to smoke again. im thinking the shop took off just a little too much from the head and the compression is too high therefore blowing another gasket. so i think i am done with this 7m. it has 201xxx miles on it so i really dont think it is going to last a few more years. :( so my new question,

what would i need for a direct drop in for a 1jz-gte. ecu?? would i need to re-route fuel and brake lines? would i need to make a new exhaust that would bolt up? i know the tranny still works but with a different bellhousing. ( am i correct???) and what do you think would be the final cost for everything?

>"im thinking the shop took off just a little too much from the head and the compression is too high therefore blowing another gasket."<

Highly unlikely, especially if you haven't used full boost. I just reread this whole thread and didn't find any comments about it smoking before. What color is the smoke? Pull all 6 spark plugs and shine a small light into each cylinder. If you see any water, it's probably the head gasket again. If they are all dry, it's probably good. How much does it smoke? Maybe you can drive it thru the winter, save some $$$, and determine if the smoke is just valve seals/guides or rings/bearings. Worn rod bearings will throw a lot of oil on the cyl. walls, more than even good rings can handle.

Well.. JZ-GTE's are excellent motors, but its not simply a dump and go operation from what I have read so far. The engine may be totally fine mind you.. but I have no idea what you done in total or what the engine has been through prior to your posts. However, I do have an issue with the 201xxx miles comment. We are in km's in Canada and 62000 miles is roughly 100000 kms. So... 201,000 miles is gonna be over 300,000 kms. If you get an engine to that point without rebuilding, I applaud whoever maintained it, because they did it right. The engine is still good, but a rebuild may be necessary. (you would know that better than I) One of the rules I use is, if you take an old engine and rebuild the top end... your gonna blow the bottom end... so... you dont do things half way.

So.. my question is... you replaced the head gasket.. anything else?

Others will correct this statement if I am wrong, but your farther ahead money-wise if you rebuilt the engine yourself. I wouldn't ignore the turbo though (this is a 7m-gte right?) but personally I wouldn't do the turbo myself because it has low tolerance for error.

I am not a trained mechanic but have rebuilt a few engines long ago, and the rule of thumb then was, Head gasket gone? Do a valve job. When you do a valve job you do the rings... at that point... you just say.. oh what the hell and do the whole engine. Its not that much more money if your doing it yourself.. although I shudder at the thought of rebuilding a 7m-gte... :) It looks like a real PITA to get the engine out.

mind you.. I would love to pull mine if I had a month of nothing much to do! I just make more money working then I do not working, so to me.. its cheaper to have it done.. plus I have someone to bitch at later if it doesnt work.

...then there's retooling for the job...
