[Supras] Help in diagnosing strange sound - UPDATE / RANT

Thu Apr 19 15:19:46 CDT 2007

I bought new studs and nuts from the dealer, put a lot of high temp thread 
lock on everything and bent the j-tube inward a little. I did this when i 
put the head back on a while back and its held up nicely.
- Harley(87t)

>>Ok, yesterday evening after the engine cooled down, I was
>>probing/poking/listening for anything that could be making that kinda air
>>compressor motor sound on my 92T.  At this point, I'm starting to think
>>it's
>>the leaking manifold gasket......sounds weird?  Well, I've noticed this
>>leak
>>for a while now and I've attributed it to the fumes in the cabin mystery
>>which I posted here a few weeks ago.
>>The leak is getting worse and worse.  I've listened to the sound carefully
>>and it sounds like.....get this......tugga tugga tugga tugga tugga
>>tugga.........yes, this coming from the leak on the manifold gasket way at
>>the back behind the turbo.
>>The more I drive this supra daily, the more things I discover is going bad
>>and needs maintenance.  Here's a lists I've got so far:
>>- Leaking exhaust manifold
>>- busted rear shocks....leaked oil on my garage floor like 2 years ago
>>- leaking oil hose.......the hard one behind the alternator
>>- check engine light....stays on for about 5 mins when engine first 
>>started
>>cold - asked about this on the list a while back.....Code 21 - Oxygen
>>Sensor
>>Heater Signal
>>- AC.....converted to r134a last Friday and still cold for the 80F Tampa
>>days.....who says r134a not as cold????  Still looking for oily residue
>>anywhere that could indicate freon leakage
>>
>>Another thing I've noticed also is while in stop and go traffic, when
>>taking
>>off, the engine sounds noisy....like the oil pressure is not building up
>>fast enough or something.  Reason I think this is because it's the same
>>sound I get right after I do and oil change and start the engine and rev 
>>it
>>about 1500 and the noise just dies out after about 10 seconds.
>>
>>So far, these are the problems I've noticed since I started driving this
>>car
>>daily.  After I get the Tercel back on the road, I'll start working on the
>>Supra.
>>
>>I enjoy driving my 92T and I enjoy working on it and fixing it up........I
>>told my wife this Supra will die of old age instead of driven to death
