This sounds like a classic case of blown head gasket.

You seem to know some about cars, however I will attempt to give you my best answer.

You have a gasket that seals the engine to the head, when you over heat this gasket gets punished and in some cases the head can get warped and the seal between the engine and head is lost resulting in your loss of compression.

You need to remove the head for a better look, take the head to a machine shop and have them check it for warped condition, if so see if it can be machined flat, also look into a rebuilt head, it may just be cheaper to do that then the work to fix your original.

As well your going to have to find the reason the car over heated in the first place..

This might be a good time to see if the car is worth fixing?!

What should the compression be at on a 1997 geo prizm.


which engine. the 1.6 or 1.8 toyota engine (its a corolla in snake skins) 4afe or 7afe ,
cold or hot?
warm / hot , is specified in the Factory service manual.
most cars get at least 150PSI (wide open throttle) hot (warm) , sparks out.
the compression ratio is the key factor for compression.
The 7A has 9.5 CR, way more than the 4A.
if way low on all cylinders the cam belt slipped, ever do a belt job at 60k?

here is an actual test off a good, 7afe
Compression test dry: CYL 1=210/CYL 2=200 CYL 3=205 CYL 4=205

when the belt slips the PSI can drop to 90 easy
and fail.
rules:
battery charged
spark plugs removed
block open throttle (and if smart pull fuel pump fuse)
crank until the needle goes steady. using remote start cable at starter lug, works best (safety , 3 ways)
bingo
repeat

After overheating my 2007 cl550 wont start


Hi Bradley an overheat can be serious and unfortunately can damage the cylinder head gasket, piston rings and pistons leading to poor compression and a non start, Without coolant the engine becomes super heated best advice first thing to do is a compression test on each cylinder diesel engines require at least 350 psi petrol engine at least 200 psi hope this helps Richard

2008 dodge hemi quit running. Fuel pressure 60 psi, good spark, and had po340 cms sensor code. Replaced sensor, same code. Did a compression test, #5 #6 #7 #8 had zero compression. #4 had 30 psi. I am...


Code340 means the computer is not getting a signal from the cam sensor for one bank. Since you replaced the sensor, and given the fact one side has no compression, it could be that there is no signal because that cam is not turning.

Car wont start, replaced fuel pump. Now I havefuel to cyls, spark @ plug but no ignition, maybe flooded? Any ideas? Please?


you need to do a compression test on all cylinders. All cylinders should have about the same amount of compression with a minimum of 120 psi.
if there is a major drop of compression in a cylinder that means there is a malfunction in that cylinder(bad valve, broken rings, etc
if there is a major drop in compression between 2 cylinders then that means you have a bad head gasket.
if all cylinders read 0psi then you have a broken timing belt
If all cylinders read about the same then you need to check the timing and make sure the cam(s) and crank shaft are still at top dead center (TDC)

Sounds retarded , Spins fast when starting... Has 200,000+ miles . has no power ... There is at least 2 to 5 degrees play in the crank shaft before the rotor turns . Replace is the answer ?


sounds as if the compression is weak allowing the fast cranking and that would also explain lack of power or possible skipped time- timming belt jumped a tooth all of which says engine is tired yes.

2001 tiburon won't start i have replace the fuel filter plugs cables coil pack fuel pressure regulator. i don't know what else to do. may be is the timing belt


sorry your tiburon won'y start and you have spent so much money with no results.so lets start with basics, is battery voltage at least 12 volts and does the engine crank over ?, next do you have fuel pressure of 50 psi and good volume?remove a fuel injector electical connector and test for injector pulse.then perform a fuel pressure drop test on each inj.this will tell you if they are spraying.do you have good spark at all the sparkplugs? perform a compression test, spec is 203-218 psi. next you will need to check camshaft timing by bring # 1 cyl. to tdc on the compression stroke and checking the timing marks on the crank and camshaft gears.wish you the best let me know the results.

Car wont start after over heating


Sometimes when the waterpump leaks it leaks onto the timing belt making it slippery the timing belt probably jumped a tooth, to check this purchase a compression tester unscrew a spark plugs and screw the tester into the spark plug hole, have an assistant turn the engine over for 5 seconds wright down the reading proceed to test all 4 cylinder the compression should be a minimum of 110 psi on all if one of the readings is 50 psi the timing belt must be replaced, either way you must perform a compression test to rule out a timing belt issue first.

Not firing right on no.4


First check plug and make sure the right plug for this vehicle,make sure that the heat rating for this plug is correct. Your problem could be a wrong heat rating plug been installed. Also make sure that the misfire is due to a bad plug and NOT a bad injector or injector wiring or uneven compression or even bad coil. Check injector wiring and make sure it not shorting or broken. To check injector pulse use a NOID light can be bought at almost any auto parts store like Auto-zone etc. Also compression can be checked with compression guage. A rule of thumb to go by is if any cylinder has more than 10 PSI in difference in compression there is a problem like a burnt valv etc. Here is a n example cyl# 1 170psi cyl#2 176 psi cyl#172psi cyl# 4 150 psi, there is a problem with cylinder # 4 and will cause a miss from cylinder #4. Good luck and thank for using FIX YA

Wont start


Have you checked the cyl compression yet? If the compression is too low, it will not fire even if you have air, gas and good spark and properly timed. Ford recommends a minimum of 101 psi, but the truck should run (quite roughly I might add) on 85 psi.
