Engine/Transmission (1994 - 1998) looking for overflow valve repair kit part #

[Andy Redmond]

Iceman:



The reason for the razor sharp spring is the seat that fits between spring and the ball. It looks similiar to a "push nut" or a "hat" the reduced end goes inside the spring and the larger end rests against the ball. I'm guessing it slipped out during the "tweaking" process or was never present, hence the early failure.



Shimming is a viable alternative, with good results oftentime.



Search several posts I made last fall for the latest greatest part number and the bosch tsb I referenced. You want the the bosch number ending in 092 rather than 086. Their may be another greatest part no. , by now. .



Piers price is hard to beat! Maybe a new one is a simple solution.



On the spring my transmission buddy, James Northrum (Inarush76@aol.com) and I have played with some transmission valve body springs and the ball valve, they are both sae rather than metric and significant r&d is necessary to get the spring just right, only to have the spring give unreliable results.



Unless the exact or near exact oe parts can be sourced, you are chasing your tail and creating an unreliable fuel psi situation (IMHO).



Good luck,



Andy

COOKER,checkes this morning and no stumble. i plan on putting the 15psi fp gauge i have in my 01 on the 94 soon. the 01 needs a 30psi gauge anyway.



ANDY REDMOND,,there was no spring seat between the ball and spring when i took it apart. maybe this could be the problem?

ICEMAN, a 15 psi gauge won't work on your 12 valve, you need at least a 30, 40 is preferable. Normal fuel pressure should be 18-24 psi.

I'm not sure if this has already been address but I believe the overflow spring is a standard compression spring? I purchase springs for work and use Lee Springs & Century Springs. Both companys stock thousands of sizes.

All you need to know is Material (music wire, stainless steel or oil tempered), wire diameter, Inside diameter or OD, and free length. Also total of number of coils can help too.

Overflow Valve Spring

I know this is going to be a gross over simplification - but if someone has an old valve,drill it out so the spring can be removed. Then measure the lenght of the spring,measure the I. D. of the spring and the O. D. Then measure the wire size. Count the number of coils and you should be in the ballpark. It would be helpful if you could put it on a spring tester to test it for pressure for a given length.

While you have the valve apart measure the ball size. These are nothing more than ball bearings that can be bought most anywhere(Mcmaster Carr) for one place.

Piers? Contact info?

I'm in the market for a new OF valve and the best price I can find is $85.

I'm presently in the L. A area and if anyone knows where I can get one at a decent price please post it.

If Piers is still the best, how can I contact them to order one and get it shipped?

Thanks Much,

Steve



PS. I'm counting down the days until I relocate to Washington State. California has lost another tax payer.

 

[illflem]

Someone found then for $20 recently but I didn't save the info, that's about what they're worth.

If no one else can remember Piers is http://www.piersdiesel.com/

Overflow valve

I called Piers and paid $55 plus shipping (3 day UPS).

Better than $85 plus 8. 25% sales tax.

Readying myself for the big move from Los Angeles to Montesano Washington. After 25 years I've had enough and I'm vacating.

 

[illflem]

Mean to say you aren't sticking around for the BIG vote?

I don't blame you.

I've noticed latley that my milage has went down about 4 MPG here in the last 2months. How soon do the overflow valves start going bad. Mine hasn't been replace before. Would age and miles have somthing to do with it? I see white smoke on start up but as it warms up, it goes away.

 

[Cooker]

bighammer has a source for $20 overflow valves. If I remember correctly they are not Bosch but I think they are working out just fine. Shoot him a PM and he can probably send you the number.

 

[bighammer]

If you can get the whole valve assembly for $20, why bother looking for parts?

 

[illflem]

Because we're waiting for you to tell use where to get them

OF springs

on the OF springs and all the questions, Drawsen done some experiments with the gun springs, and found that they failed, to much heat in the area that they live, not enough temper in them. i have a spring manufacturing place in my location and was concidering having them made. at the time there was not enough disscussion about them, couldn't see spending mega bucks to have made if there was no demand for them.

if your thinking about stretching them BECAREFUL, go easy and not over 0. 550" this is just a hair over 1/2". done mine twice, second time was still . 550", just reinstalled. hope this helps some of the guestions.

just my penny's worth.

Marv.

 

[Cooker]

bighammer,

We are still waiting

 

[bighammer]

OK, I think I've sent a PM to all in this thread who sound like they want one. I thought about posting the info for everybody, but the savings in one overflow valve would pay for a TDR membership. Am I wrong? Should I just post it?



If I missed your name or you are interested, shoot me a PM.

 

[Cooker]

Good thinking bighammer.

DANG, I kinda like the sound of that. Oo.

 

[illflem]

A lot of folks are under the false impression that you can't post contacts and prices for items here.

The rule only applies if you are the one doing the selling.
