ANOTHER DSM THAT WONT START
 

ok fellas well my buddy bought a 90 talon tsi .... the guy he bought it from is a pretty good friend of mine that i trust ... he was driving the car one day and it started to over heat... he said before the gauge maxed out he shut the car down ..let it cool off for awhile and then try starting it again .. well it wouldnt start back up ... the reason it over heated was becouse a coolant line broke so he replaced the coolant line and took it home.. tried starting it still nothing ... the car seems like its just not turning over hard enough .. even with a brand new battery ... it turns over the motor isnt seized or anything ... then we did a compression test even though it wasn't turning over very hard the results wer ..... 0-0-0 and like 8 psi on cyl. number four.... what im wondering is it possible to jump the timing that much that there would be 0 compression on 3 of the cylinders... or if its not turning over hard enough would it build compression ??? any answers or ideas would help.. this is our first time working on one... thanks in advance

Re: ANOTHER DSM THAT WONT START
 

If it over heated long enough it could wrap the head and your headgasket would leak = low to NO compression,
Check all the plugs for oil/coolet, check dipstick, look inside the valve cover for miky/ muddy oil.

If engine is not turning over fast enough then yes the compression will read low.

Re: ANOTHER DSM THAT WONT START
 

not that low thou.

i got 50psi turning my 350 over by hand 8)

Re: ANOTHER DSM THAT WONT START
 

lol i got like 10 psi out my my D16 hand cracked :S

Re: ANOTHER DSM THAT WONT START
 

sounds like he shot the timing belt.

better order some parts from www.quickwhips.com hahahaaha

Re: ANOTHER DSM THAT WONT START
 

email or message dlanda or koby, both live around me and know their ---- when it comes to dsm's.

Re: ANOTHER DSM THAT WONT START
 

haha... ur friend fucked up =x dsm = nothin but trouble.

big pwobwums

Re: ANOTHER DSM THAT WONT START
 

its not the timing belt becouse the cover is off and i seen it spinning .. plus its 2 weeks old timing belt ..oil is not milky .. car ran fine before didnt smoke nothin sp i dont the rinds just went out no grinding or anything when turning over..

Re: ANOTHER DSM THAT WONT START
 

First things first. When you overheat a car bad the headgasket is the most obvious part that will break/wear first. So naturally our first step here would be to either just man up and replace the HG (easy 1-2 hour job even if it is your first time) or you could just even check for the signs of a blown HG (oil in coolant, and vice versa. aka chocolate milk coolant)

Well, beyond that, there is no reason that your engine should be getting #'s that low on a compression test. Are you pressing the throttle down 100% while doing the test? Try pouring some oil down in the cylinder and then testing it. If you do have a fucked headgasket (the most likely situation) you will probably want to get the head resurfaced, or at least checked out. The blocks are iron, you shouldn't have to worry about it having any warpage just yet.

If your somewhere here in the northwest I can put you in contact with a local person to give you a hand, hell theres always a DSM guy around to help ;)

Re: ANOTHER DSM THAT WONT START
 

im, in the midwest .... there is no milky oil which make me think its not a hg .... there no oil or coolant leaked down the motor and there was no oil on the old plugs... i just dont know what could affect compression that much but had no signs ... like if the ignition resistor is fuct up and not turning it over hard enough would that effect compression ...

Re: ANOTHER DSM THAT WONT START
 

???

is the compression tester working right?

Re: ANOTHER DSM THAT WONT START
 

does anyone know where the ignition resistor (moduale) thing is at on the block

Re: ANOTHER DSM THAT WONT START
 

How slowly is it cranking? If it just cranks somewhat slower than normal, there's definately something wrong. If it barely cranks over, you may end up with numbers like that. You said that the timing belt is two weeks old, so it's possible it wasn't tensioned right or something and allowed it to jump a few teeth. Make sure the cam timing is correct and go from there.

Re: ANOTHER DSM THAT WONT START
 

well it ran for two weeks and we tensioned it properly with a new tensioner ... its wierd and hard to explain but normally when you crank a car over it goes baw-wam-wam-wam this just goes bawwwwwwwwwwwwwwwwwwwwwwm if that makes since to anyone its hard to explain ...the cam gears just looks like there spinning very slow . possibly cam positioning sensor ?

Re: ANOTHER DSM THAT WONT START
 

Another one bites the dust.Doesnt matter if you put a new one on what matters if it was setup properly.8 out of 10 peeps i bet dont have the proper tools to do it correctly.
first thing i would do is tdc it You need to rule out the the belt issue.
second check for comp....hmm 0 0 0 3 car overheated wet an dry comp test
depending on that results we do a cyl leak down to see where the leakage is going.
if the rings are washed down you wont have an compression.


Go to the basics first
Do u have spark?
Do you have fuel?
Do you have compression?

you need these three components to make an engine run

There is a charge for Healing cars over the PC so fork it over,,,,,,, :D

Re: ANOTHER DSM THAT WONT START
 

haha fork it over???? you said what everyone else did ... the car has spark and fuel .. but if the valves are staying open it cant build compression .. so that were im stuck

Re: ANOTHER DSM THAT WONT START
 

:o i dont see how your stuck...... :1 no compression? timing belt jumped? rings collapsed? pistons galled seized rings?

Thats where your at. did you double check your timing makrs for the t-belt?

Re: ANOTHER DSM THAT WONT START
 

yea i know to check the timing just havent gone and done it becouse some people say its a waste of time becouse jumping teeth will not put you and 0 compression .. i dunno im ganna try it anyways and see if were off

Re: ANOTHER DSM THAT WONT START
 

yep, check your timing marks leakdown if you can. you shouldent have 0 psi acrost the board if somthing isint fucked up with timing. it just sounds like the motor is free spining right? like when you take the plugs out of a motor and turn it over.

Re: ANOTHER DSM THAT WONT START
 

Jumping teeth can cause 0 compression. My belt on my old GST had that problem. Bunch of oil spilled over by the timing belt area, caused the t-belt to slip, and I ended up with a bunch of broken valves. I had 0 compression in 2 of my cylinders. I would say take the head off and check for damage. Bring the head in to a shop and have them test it to make sure nothing is warped or damaged.

Re: ANOTHER DSM THAT WONT START
 

where did your friend buy his talon from? cause my friend just sold his not to long ago to this one dude...and right when he got out of my friends driveway, he floored on the gas and fucked something up...i was just wondering if it was ur friend or not?

Re: ANOTHER DSM THAT WONT START
 

word well i will check the timeing and see what is going on but i hope that the vavles aren't broke they are brand new ferra 1mm over's that would suck.... but thanks keep the ideas coming....


and i don't think that it was me i had to trailer it out..........
