Engine Heads Questions:

Question #1:

Air conditioning is not cold?

Air conditioning is not cold?
air conditioning is not cold?
i hit a 96 camaro 3.8. earlier today i was driving and thought it would be a good intent to permit the ac separate for a little while. while it was hurried to change from heat to ambient algid air, the expose never rattling got colder than ambient temperature.

when i got home i opened the cowl and saw that the rotate thing on the end of the compressor not the connatural drive wheel, the modify "clutch"thing was spinning when the ac was on, and was not moving when the ac was off, just as it should.

when i overturned the engine off, i found that the same wheel on the modify of the compressor was pretty easy to twist. when i twisted the rotate by assistance i could hear a fearful gurgling noise reaching from around where i envisage the heater core is, or something around that area.

when i ran the automobile with its hood open at the warmed-up low idle, about 650-700rpm , with the ac on and the rotate on the compressor spinning, after most a minute i cound not rattling feel any change in the temperature in the silver chamber thats in the ac lines between the compressor and the exclusive of the vehicle evap. canister? . it not rattling get hotter or colder.

what do you conceive is wrong? i dont undergo when the old guy i bought it from had last run the ac...

please gratify please be healthy to tell me that it is meet becasue the ac has sat clean for a while,and it meet needs to run for a while at superhighway speeds with the ac on or something same that... or maybe the automobile takes the intake expose temp and only activates the ac when the ambient air is hearty it was 64 in the candid solarise when i drove it today ?

i patterned the lines as much as i could see exclusive the engine bay, and there is no evidence of a leak at any of the connectors. i obviously slope see anything time the firewall, bu there was no sitcky residue or anything on some of the connectors in the engine bay. i also took off the cover of the valve thats rght before the upper connection to the air conditioning radiator i know its called something added and, using the head of a nail and a file, i place the head of the nail on the tio of the regulator an just barely broached the end of the nail until i could center an extremely hurried blow of air. im sreious it was some some times shorter than the puff of air you get when you take a ring viscus soured a ring valve... when i finally did promulgation a tiny blow of gas, i sounded like there was a aggregation of pressure behind it, more than a ring has. so there is in fact freon in the system.

i rattling dont poverty to have an ac difficulty hunt...

thanks

Question #2:

Does synthetic engine oil reject heat?

Synthetic engine oil has been hailed as the ultimate engine oil as farther as lubrication, durability, tolerance to algid weather and knowledge to withstand heat. However there has been a older saying that synthetic engine lubricator rejects heat. Has anyone compared synthetic and lawful oil in terms of modify transfer? Is there some content on the limited heat capacity and the modify conductivity of synthetic engine oils? Are there brands that hit assorted properties?

The reason I communicate is because I possess a 1972 Super Beetle Type 1 1302 . The engine is expose and oil cooled. According to whatever experts, same Gene Berg, polysynthetic is not good for such an engine, saying that it rejects heat. Others like at aircooled feel the complete opposite.

The results form both sources have one abstract that is suspiciously the same. The temperature of the oil runs cooler. One says that it keeps the heads hotter and the other maker says that it won't change the heads' temperature at all. Why is that? Since its last places were the bearings and the heads does that mean that it has less heat conductivity than regular lubricator and so stays cooler after passing finished the oil cooler and not attractive modify along with it same it should? Or does it have a higher heat power but not sufficiency to affect head temperatures? Or is it that it just creates less exertion and therefore less heat same whatever others have said which is kind of hard to for me to believe ?

Question #3:

Find a movie by description!? HELP!!?

From what i remember, Its an action/thriller movie.
theses are the small details that i can remember:
Its ordered in the future.

Question #5:

Does a blown head gasket or cracked head make the motor shake a little bit more detailed?

Ok so i unstable the motor and every that so when i countenance at the wear manifold towards the firewall at the back of the motor. It leaks at the exhaust increase a white opaque color as if i have a blown nous gasket or unsmooth head? but the motor as a lowercase bit of a stir to it it was actual bad but then i overturned the engine soured waited for a while and unstable it again it wasn't as bad?
its a 1997 Isuzu Rodeo 2.6L and the oil is not milky just runny and has bubbles. It has a blown head gasket or warp/crack head
it did over heat when i was going downbound the high way i think that is what cause a cracked/warped or panting head gasket and the car died on my going downbound the road
lol noo im not responsive my question. and yes it over heats or it did i have not ran it long enough to undergo it it module over heat as it did when it panting a nous gasket or etc. and my question is way does the locomote shake?

Question #6:

does this sound like a bad intake manifold gasket or a head gasket? or what else? very detailed 99 grand am gt?

please help me out i cant give a journeyman my lake is empty over period with no puddles on connector my automobile averages on 200 degress it overheats rattling easily ,steam comes discover the lake and i hear bubbling noise in the radiator after finished dynamical the heat only works sometimes i drained the radiator and healthy it with advertizement products, and the car will no qualify fast, i can story it and itll be loud and rpms go no more than 4 but it ease accelerates rattling andante as if im just touching the pedal and doesnt switch gears easily, the maf sensor is intense and i undergo it, but im 16 and dont hit sufficiency income to buy a new one only making 200 every 2 week at current job,i did oil modify on tranny and engine and denaturized pcv , spark plugs, render filter,air filter,fuel pump,and ran 2 bottles of seafoam in oil, gas and the clean lines,i the check engine light,low coolant,and assist container soon light is on at every times,fans are employed i got the codes pulled and it came discover as maf sensor and engine misfire detected, the previous owner thought the accleration problem was the felid converter, he removed it and he said his chum said it was a 90 note gasket, the car wont qualify fast but does decent if i unplug the maf and it wont go over 45 and it has high rpms at that pace and it seems to hit switching problems correct when it should alter the automobile shakes backwards and forward but not alacritous and it loses whatever power but makes a weird racket kinda same its hiccuping but the exhaust pipe changes sound as if its coming discover a tube which it is , low the throttle embody just beneath on the engine theres some brown stuff thats been absorbed but sizzles after driven it feels same lubricator but if its leaking its a tiny revealing but older one ,

Question #7:

I think my brain works differently to others?

I am digit of those people who seems to know everything and ever has an opinion on things, i can sit up all night just researching completely haphazard things that help no connexion to anything, and then i remember these facts boost on down the line, my friends call me google lettuce they say i am like a search engine.
But inferior of that, i feel like i over think things, my lover says that i notice every little discourse most everything, and before i do anything i have already prefabricated a plan in my head of every doable outcome, i am really clever don't mean to be content but its true i do not need to reorganise for my exams and i get A grades, just peregrination if anyone else feels same this, or am i abnormal ha ha?

Question #8:

Car issue after engine rebuild..?

2004 Mazda 3
2.3 hatchback
5 speed.

So this is what i did
I distant the engine cod to handgun knock/welded bearing

Did a rank rebuild
flywheel
clutch
Balance shaft withdraw kit
Cos-worth Crankshaft
Rods
bearings
head gasket set
seals etc
but i didn't change the oil viscus

when everything was said and done it started right up and ran really smooth and good, no leaks, no smoke from the exhaust.. everything meet perfectuntil..

My Problem is this..

When i move the car and yield it running, it runs uncreased and works perfect,, it revs substantially and runs at idle 700-800rpm

When it hits operative temperature it runs almost like its firing the spark at the criminal instance on one of the cylinders and it starts clunking and squealing a little likewise substantially i never let it running long sufficiency to check it discover i ever invoke off at that point...
and also when it hits operating worker i cant rev modify when i rev it, it meet starts stalling and running rougher.

No overheating
The lubricator push from a mechanical judge is 80 psi on cold move and settles at 30 psi after it warms up....

what could this be?
I know i didn't modify the lubricator pump as i was questionable to but the feeler gauge was within specs..
I have Changed every conception eliminate the pistons, rings and oil pump...

Question #9:

What else could be the problem?

So, I detected my car leaking and the mechanic told me it was the water pump. So, I verify it to intend repaired. He realizes the water viscus is fine, but sees a hose that wasn't on every the artefact so he tightened it. After both repairs he said it was still leaking, and came up with the diagnosis that my nous gasket is cracked. I presume that it's in the aforementioned area, and it's ofttimes mistaken for a intense waterpump. Is there anything else it could be?
It's also overheating as well.
'97 Chevy Cavalier, 2.4 Twin river Engine.
I'm meet doing a terminal instrument before it gets junked tomorrow.

Question #10:

Should I buy 1983 Porsche 944 for my first car?

Well, it would be my prototypal automobile and it is a 5 speed. 167k miles on it and it is 4000. Is it worth it and would it be a good car for me to change to school and to work? All it needs is a newborn nous gasket cover. Guy place new brakes, brakelines, and a officer cylinder in it. Here is the unification
