ya, i went to take my roomate out for a ride and it started acting funny again, it didn't try overheating like it did before but there is more coolant/less air in the system now, but it still was trying to slowly overheat, so i shut it down a little over 90 degree's this time, stock gauge was higher than it should have been but not to high... next step is to get the pressure tester, anyone wanna ship one to me? ...

and i agree gadd, i think what he was trying to say was noone was telling me to just burp the system and be done with it, and that it definitly was not a fix to cover up another problem, but that burping the system is definitly something that needs to be done, your both on the same page as far as i can tell ...

i'll have an update as soon as i can get my hands on a pressure tester ...

thanks,

James

[edit]also when i started it up last nite it smoked quite a lot again, but did not smell like coolant, more like oil, it smoked a little when i went to take off for the MSU racing meet but cleared up as soon as i started driving it, just something these cars do on a cold startup?[/edit]

got a pressure tester today and put the system up to 13.5, and it dropped, and i could hear some sort of leak somewhere, but we couldn't see anywhere it could possibly be coming from, we traced the line that goes from the block to the TB, we couldn't see it but we felt around the base of the line and it was dry, aside from that i have no clue what line it could be judging from the coolant diagram in the newbie FAQ, i wasn't brave enough to tear apart anything on the turbo setup plus i didn't have the time really, any suggestions?

1. Remove your undertray, and carefully check the radiator and lines from below. It will help if you can get the car on a lift. If not, put a piece of paper or cardboard under the engine and pressurize the system. The drips will show you where to start looking.





2. If you can't fine a leak, and are sure you've thoroughly checked all the coolant hoses, search for "blown coolant seal(s)."



Good luck,

well it does drip, cus i've had drips under it a few times now, and its in the back of the engine bay on the passenger side, like right under the rear turbo...

i had a leak that was wetting under the turbos and onto the ground under the turbos, basically right under the 2ndary. the turbo actuator arm was wet, as well as the shielding directly under it, and the suspension crossmember under that. from there it dripped to the ground.

over the past 4 days i think ive finally found the problem, my front water pump gasket was leaking and the coolant was making its way to the RH side of the motor then down the parts i mentioned above. at first i checked the turbo coolant hoses and other sources in the area but nothing was leaking there.

i patched the gasket with some jb weld putty(thanks kevin). u may want to look there as well, altho i may also have a problem with the water pump-to-motor gasket as well. gl

this guy reminds me of Ramy about 2 years ago, ha

me? well ramy seems like a pretty cool guy so i suppose i'll take that as a compliment right now ...

and thanks sevensix, i looked around the waterpump but i'll take a closer look again, i've been so busy with work and school (and now being sick off my *** argh) that i haven't taken anything apart, tomorow i only have to be at work for a couple hours so i should be able to do it then...

alright guys, got everything all tore off (way easier than i had thought it would be ) and it does not appear that either of the turbo coolant lines are leaking, i might only be looking at the feed lines and not the return lines though (these are the only ones i can really see)... but we found something else that a lot of coolant seems to be resting on right next to the downpipe, it is like right under the rear turbo (secondary?) and it seems to build up a little more coolant everytime we pressurize the system, not much, but a little, heres some pictures that i snapped, its right above the crossmember on the passenger side towards the back, right under one of the turbos, you can see the oilpan bolt in the first picture as well...

2nd picture is a different angle
3rd picture is a close up of the little spring looking thing (what is it?)
4th picture is of the soft line going from the WP to the hard lines to the turbo, it looks fine to me and is bone dry all around it
5th picture is the front turbo hardline where it connects to the turbo, it is also bone dry all around it

6th picture is of the rear turbo hardline, you can't see under it in the picture but i could see while i was under the car and it is dry underneath as well...


so, any other opinions? doesn't seem to be the turbo lines, and i have no freaking clue what that coolant is resting on, but it kind of looks like it could be leaking from where that mates up with whatevet it is bolted to (the block? turbo manifold? i dunno)

anyway, as always any help is appreciated, i'll be searching after i post this as well...

bump...

bump, is there another coolant line up above and to the left of the manifold in the 2nd picture i posted?

There are four banjo fittings on the turbos, two are on the engine side of the turbo under the heatsheald and are hard to see but are visable from under the car. I didn't see a picture of the lower rubber turbo coolant line, are you sure that one not leaking? Also, check the weld where the banjo fitting is attached to the hard line, I've seen them leak there.

exactly what i was looking for , i'll climb back under there in the next couple days and check all that, i thought i looked it over pretty well, maybe i should pull the downpipe? i dont really want to but i guess if it would help... i thought there was another rubber line so i was questioning myself on that, but then just chalked it up to me not reading enough, and i think i was mistaking one of the oil lines as a coolant line...

im having the exact same problem as you without the overheating.

when you unflooded the motor did you notice the stuff that sprayed out? mine seemed a bit like coolant mixed with fuel.. like it smells like fuel at first, but then doesn't evaporate quickly like fuel.. it just loses the smell and smells watery.. plus i swear its a bit green. plus during unflooding did white smoke come from the turbo side of the engine?

in regards to the pictures u took. i had coolant wetting the exact places as your pictures. EXACT.

although i previously mentioned the water pump leak.. i now know that what i patched was definitely not the problem. not sure if that's worth you looking into.

as far as the 4 banjo bolts for the turbo coolant lines, u can reach them w/o taking off the piping. i did and was able to torque 3 of the 4 bolts, i gave up on the 4th one, the first 3 were pretty damn tight plus there was no sign of leakage around any of them.

ya i looked my WP over and its bone dry, i still have a few coolant lines i need to check over, hopefully one of them is the culprit, it would SUCK to have this problem be worse than a simple cracked line...
