I would check the wires on the oxygen sensor. They may be melted together and shorting out. I just had a similar problem with my 87 Supra. The 7.5 A ECU-IG fuse kept blowing and I wound up having to replace the ECU - which drives the fuel injectors by the way. I got a used one from the recyclers for $120 and it fixed the problem right up!!

It did on mine. When I went to check the pump, the fuse was blown. Replaced it and found that the pump was also bad.

How do you blow a engine turbo.

User Avatar

Where would you put a blow off valve on a non turbo, and what would it blow off? So the answer is no.

User Avatar

blow by through the turbo ,my truck did the same thing had to get the turbo rebuilt

User Avatar

No, without a turbo, there is no blow off valve. However, if you really wanted to, they have fake blow off valves for sale. These mimic the sound of a blow off valve. It would be an absolute waste of money, but hey, it's your money.

you could have a pressure leak when the turbo spools up... check all your clamps and check for cracks or holes in your intercooler

User Avatar

No, there is no reason for it. In turbo cars you have intercooler pipes that need pressure released at certain times. You have no intercooler in non-turbo cars. I guess you could install one if you wanted to look silly, but it wouldn't serve any purpose or be functional. I hear you can get a fake bov that makes the sound, if that's what you are looking for.

ofcourse they do, they blow on any engine

User Avatar

not really. You can get blowby in the turbo itself from high crankcase pressure, but a turbo won't cause engine blowby.

User Avatar

yes you can put a blow off valve on any turbo application, A blow off valve helps relieve boost pressure spike/surge when the throttle is quickly closed, helps prevent damage/excessive load on the turbo and throttle body.

Install a blow off valve, it releases excess pressure from the intake side of the turbo

User Avatar

make sure you have not blow your turbo. If you did not blow the turbo you might have put a hole into the intercooler. This will cause you to use a ton of gas

User Avatar

Amazingly pointless. The blow off valve is there to release intake pressure if you have the turbo spinning and then go off the throttle suddenly. If you haven't got a turbo there's no intake pressure to release if you go off the throttle.

User Avatar

You could mount it, but there is no pressure to blow off.

is this a diesel truck?does this engine have a turbo?if it is a diesel with a turbo,it will blow white smoke when cold till it warms upif it continues to blow smoke check your air filterother reason if it continues to blow smoke is the turbo is about to crater get it checkedalso check engine oil for coolant lossif coolant is leaking into cylanders,this will cause white smoke

User Avatar

NO. deffinatly not. you need to have a turbo on you car! wow what a ricer

User Avatar

Technically you can, but unless you have a turbo a blow valve won't do you any good. It's be like hanging sidepipes on a car and not hook them up.

User Avatar

Only gas engines use blow off valves.

User Avatar

The same way any other whistle would work. You blow and it makes sound. Where here your exhaust does the blowing

User Avatar

You can, but it'd be amazingly pointless. The blow valve is needed on turbo engines to release the pressure that can build up if the driver goes off the throttle quickly and the engine revs drops fast. W/o a turbo you won't get any pressure build-up so there's no use for a blow valve.

They got it to work on a bike...

no, bov are mounted on turbos
