I've got a problem here. I just changed the alternator/fan/crank belt and put a little WD-40 in my BOV and now in first gear I only get a full 4 pounds of boost above 6k rpm and in second gear it goes to 6 very slowly, full boost at 5000-5500 rpm. What the heck is the deal, it was working fine before I changed the belt and put the lube in the BOV. And I assume it'd be audible if it was a boost leak the big. Can someone please take a jab at my problem?

 

wd40 is the sperm of the devil. You messed up your BOV by spraying the devil sperm on it.

Never ever use wd40 on anything on your car.

 

bahhh! it creeked a couple times when I let off before this. I was going to grease it but can't open it up to get to the mechanisms. Do you think the BOV is the root of the problem? What do you think I should do about it? Maybe vent it back into the intake

 

Ok, I pulled off the BOV and plugged the hole. Still doing it, so it's not a problem with the BOV. I just don't freakin get it, one minute boosts strong, the next it boosts like a moron. The only reason I can't think of is that there is more load on the engine now since this belt is in alot better condition and actually runs the waterpump, lol.

 

lol, wtf??? I've heard it's bad for parts that require grease and not lubricant based sprays because it breaks the grease down but I thought it was good for like throttle linkage lube and what not.

 

no, WD-40 is awful. It lubricates at first... then builds up into gunk. don't kill me if this makes things worse, but try using brake parts cleaner. that stuff will degrease anything instantly, and get rid of that gunk. then find out what the proper way to lubricate the BOV.

 

How About We Figure Out The Real Problem! Crappy Boost Response!

 

No change in Idle?

 

Yes, Mark, but it smells SOOO nice!

I love the smell of that stuff..


On topic: My guess is you knocked off a vacuum tube somewhere, that cuase these symptoms, right? (never had a boosted vehicle )

 

couldn't the boost response be from a BOV that's partially left opened? maybe i'm just talking out of my *** on this one.

 

Now how would one know what the characteristics of the sperm of the devil are.

Oh well, back to the point. Since you've ruled out the BOV, what other symptoms does the car have...maybe the idle is pulsing a bit, maybe you cant tell too well if it is. I would check, and double check, all the vac lines.

How much boost were you hitting in first gear, second gear, before???

 

Actually just a figure of speech- I do not believe in the devil.

But I suspect that the BOV is partially stuck open or leaking because the WD40, and that is why he is having problems.

BUt I don't think gxlspeeder believes that or tested properlly.

But if he is convinced the water pump was not working before, and adding the belt caused the problem, then he should just pull the belt off and confirm that.

 

that's what i said! anyways, brake parts cleaner gets rid of all the grease and gunk that wd-40 makes, but you need to lubricate it properly after it dries up. probably some bearing oil is what it needs.

 

OMG, I pulled the BOV and plugged the nipple it hooks too, and it still did it, it is NOT the BOV. This was a worthy thread getting worthless answers.

 

wow dood calm down if you want any help.

Eather will absorb oil and evaperate so thats is good to use as well from brake cleaner.

Check the VAC line under the UIM that goes to the FPR. And as said look for other leaks. Check if the waste gate rod is not stuck. Check shaft play on turbo.

 

no change what so ever

 

dont mean to hijack this thread even in the least but is WD40 bad to use on the pullies in the front of the motor...?

 

If you are gonna bitch then do it somewhere else.

You are the one the fucked up your car.

Did you do any of the other suggestions???

No you are convinced a belt is the answer (like a belt would have anything to do with it- prove it to yourself disconnect the belts) but you have not even done that.

No, instead you say there are worthless answers. Have you subsituted the BOV, no, you only claim to have plugged it.

Figure it out for yourself. I don't want to answer in this thread anymore and get any suggestion called worthless.

 

You can but I sugest silicone spray. It lubs the belts up and keeps em from craking wile quieting them down.

 

Think I got it figured out, my intake coupling on the intake of the turbo was cracked. Picked up a new one and built a manual boost controller from The Home Depot. Boost's a strong 8psi now.

 

so spray the pully's where they nearly meet the block or are you talking about the whole assembly in general...?

they kinda make noise and it would be nice to have them hush a little....

 

I normaly aim at the pully I want. You can spray the belt anywhere though.

 

you can buy belt conditioner at any auto parts store, works well

 

worthless answers???

Let me write down your name and remember not to even think about reading another thread you start. You jsut lost what little knowlegde and advice I have to offer.

 

no help for speed boy. oh well.....next
