loud turbo
ok so i have finally got my car up and running again, it tends to like to eat spark plugs :) but a little bit of NGK iridiums and 8mm MSD wires helps a little also. DON'T GET BOSCH PLUGS THEY SUCK MY NUTS!!! :P but back to the subject.
i just got my full 3 inch exhaust piping done, custom 2.5inch IC pipes and new greddy BOV. car is running good. but i can really hear my turbo. i mean it sounds like my claimant control is on its so loud and thats with the windows up. its seriously loud at 5lbs of boost, and thats also where my A/F ratio reads really rich. at about 7-8lbs of boost it hits fuel cut, BTW my wast gate is shimmed so im getting 11-12 lbs of boost "4 washers". i wanna say it sounds like a boost leak but i cant see anything wrong at all. and also on the IC pipe closest to the intercooler it has oil in it, is that ok? i was told a turbo seal is going out or is out. there is also oil in the accordion hose but not alot. im only throwing 1 code and that is 34 "abnormal turbo pressure, i want to say that was being thrown because the IC pipes kept blowing apart but that is fixed now. i also was thinking it may just be the BOV. so what you all think it may be |
turbo seal is probably bad mine does same thing, as far as the sound exhaust leak maybe and check your vacuum lines
|
well i looked a little closer, and one of the IC pipe couplers had a tiny hole in it, i dont know if that was the problem yet but ill find out on the way to work today :) if it is home depot here i come. i found that the rubber couplers they got down there at home depot for toilets work great. and there only like 1.25
|
well that wasnt the problem. the best way i can describe it is it sounds like when the turbo kicks on the bov starts to open, cause i have noticed that i can barley hear the bov anymore. that or the IC pipes do have leaks and i just dont see or hear them, at idle the bov is closed. but i have noticed a hiss sound from under the car near the oil pan, i have heard this sound for a while even in the past but the car had worked fine with this noise in the past. any other ideas?
|
Do you have another bov you could throw on to see if that fixes it beecause it sounds like it is leaking. The other sound is probably an exhaust leak
|
i have a hks replica bov but it has a cut spring and doesnt work very well thats why i got the greddy.
|
They go to home depot for ur car
There's a reason why they called it the home depot, Spend a little extra for reliable parts And to check ur bov if its leaking Blow to the intake pipe side of the bov If u can blow thru it, that means its already busted |
oh believe me the rubber hose coupler from home depot worked awesome, its just that pipe had blown apart so many times and i have had to keep loosening and tightening the band clamps, then i upgraded to a T-bolt spring loaded clamp, but yea i have just tightend things so many times its torn a hole, and that little hole because a bigger hole from the coupler expanding.
|
ok so i got new rubber couplers, and what you know it fixed the whole problem, turbo is quite, i can hear the BOV again, and its not running rich what so ever.
|
Thats really weird but i'm glad you got it figured out.
|
ok now im having the problem were the clamps are loosening themselves. everyday im having to tighten the clamps on the ic pipes, even my newest ones the T-bolt spring loaded ones are loosening themselves
|
ok so get this i paid 15$ to get my problem fixed tell me what you think

That was a good idea and it looks good too.
|
holy crap, thats a long pipe going across the engine bay, lol
well more heat absorb from the turbo right? i would use sum heatshield wrapping on that part if i was you |
Those euro lamp covers look good.
|
thanks guys, mm well yea i was planing on getting some heat wrap to put over it. something weird happened today though. im driving and it was a pretty long distant drive. the coolant resivour usally overflows on trips like this but it didnt on this one. so on the way back i was stuck in bumper to bumper traffic and then i noticed my engine temp was on H and almost in the red zone. so i quickly pulled off to the side checked it out. spit on the turbo and it wasnt running hot enough to sizzle the spit. but the valve covers where really hot. next i checked the coolant resiviour and it was full and looked like it was about to overflow, so i waited a little longer so i could take off the radiator cap, it was steaming when i took it off. lots of pressure but there was no coolant visible.
now i know i need to purge the coolant system cause it does the waterfall sound during warmups and after sitting at idle for a long time. but what do you guys think is going on here, mainly the overflowing of coolant. cause im getting tired of buying coolant to put in there almost every week. |
Holy crap. Dude, I know it sounds very cliche but, you definately have a blown head gasket. When you said "the coolant resivour usally overflows on trips like this" that is a dead give away. I don't care if its 120 degrees out and you are redlining it, the overflow should never overflow unless you have combustion gases entering the radiator, period. You have the same symptoms that my car had but yours are alot more severe because you just keep driving it. All it took was for mine to overheat once and the overflow was overflowing and I got sick of it and tore the bitch down. Some days it will overheat and some days it won't right?
That pipe you used looks like a downpipe. Nice stock air box :) |
damn you i didnt want to hear that. how much you think it'll cost to get the head & block machined. HKS metal beaded/stopper? <right one to use. and how about thickness i noticed there is a couple of them.? and cant forget that ARP hardware.
|
and are you sure that it is the HG that is blown because i have a friend that had the same problem and it ended up just being the radiator cap. oil is black in color not milky, the exhaust is fine it doesnt feel slick, its not steaming at all. i mean overall the car seems good it just overflows coolant, and again when it was overheating the radiator cap wasnt steaming till i took it off.
|
ok so i have a freind that works at waltz and i had him test a buch of stuff.
pressure test = OK no leaks didnt go below 6/lbs of pressure it held block test = OK - didnt change colors radiator cap test = 10/lbs OK diagnostics = needs to be flushed air bubbles in the heater core does this sound still like a BHG? or do you think it is right, because i know it has bubbles in the heater core because its doing the waterfall sound he also mentioned that the coolant was at boiling point but that is probably because there is more water than coolant. didnt feel like spending a but load of money on coolant every week :O) |
And how do you think those air bubbles get into your cooling system? Here's a clue, you have to lose coolant to gain air in your cooling system.
My supra with a leaking head gasket never had coolant in the oil or oil in the coolant, never smoked ANY color out of the exhaust pipe. Before I replaced the head gasket I changed the radiator cap 2 times, the thermostat 2 times and it still overheated. Did you remove the overflow hose from the radiator and plug the nipple for the overflow hose on the radiator? If not, then you just sucked outside fresh air into your tester causing a false negative reading. You have to remove the overflow hose from the radiator to correctly perform a block test. Come on, replace that radiator cap if you think its bad or if its as old as the car. They are only like $10 from the dealer. And what do you mean it held 6psi or only dropped 6psi on a pressure test? When you pressurize a cooling system, you should bring it up to 15psi and it shouldn't even lose 1 psi in the amount of time it takes to smoke a cigarette. |
haha thats kinda funny on the pressure test because me and him did smoke a cigerette while we were waiting. no we pumped it up to 15 and it never moved, he mentioned that it should go below 10-6 or something otherwise you have a leak.
about the bubbles i read that you can get bubbles in there when your car is cooling down it will enter through the uhhh. i dont remember i think the cap or the over flow into your system. and it only over heated once and that was because there was no more coolant in the radiator. oh and no on the block tester, never even thought of it. |
so if i block the over flow nipple and do the test again and i still get a negative reading does that mean im ok and dont have a BHG
|
Yep, trust me. I know what I'm talking about with a block tester. I actually did it the first time I used it, I got a false negative reading. Actually the very FIRST time I used it years ago I sucked coolant from the full overflow bottle into the tester. Thats why they have a fill line, so you can see if you sucked in coolant or not. Then the second time with an empty overflow but overflow hose still connected, I got the false negative because I was sucking air in from the empty overflow bottle. Then I realized I had to plug up the nipple with a friends finger lol and then I got my dreaded green test fluid. Yellow is like omg your head gasket is gone, green is like, its on its way!!!
|
you know what i was really happy to see that it passed, now you just made me scared again you suck :)
thanks alot but again along as that baby don't change colors she ain't impregnate right |
I'm telling you, watch. Put the tester on and put your own finger on it, have a friend pump the tester, you will feel your finger getting sucked onto the nipple.
Yeah you want that test fluid the same color as it was before you tested it. |
so i can resuse the same block tester? because i know that fluid crap inside the block tester is expensive i guess.
|
The tester comes with a bottle of fluid enough for about 50 block tests. You can buy new test fluid, I don't know how much it is but I know you can buy it and its probably $20. Whoever block tested it should have enough to do you again, its not the most commonly used tool in a garage.
|
well i talked to him again and he said that on the end of it there is a little cone thing that clears the overflow entrance/exit at the top of the radiator, and we also had the engine running. so we had it steaming a little.
