Greazzer Peaks & Tweaks
 

Don't forget to buy his injectors ! .

The smoothness is amazing and my fuel economy jumped by close to 5 MPG .

Greazzer's building his fan following across the pond too! I've got a spring, rebuilt injectors and fuel lift pump going on this weekend.

According to his testing, my old injectors were running 150 psi lower than spec, so the difference should be very noticeable. Safe to say I wouldn't have my fuel system cared for by anyone else.

150psi won't make a tangible difference. I've run new 240/ nozzles at 135, 145 and 150bar. No difference at all in power, smoke, economy or noise.
Balance is much more important than overall pressure. A good tester with a proper shim kit can get them +/- 2bar consistently.

I would disagree. 50 PSI or more from NA nominal PSI OF 1650 at the lower end should be avoided. Same with turbo , eg 1900 PSI. I know a few forum members swear their nozzles are not worn with 300k on the clock or PSI can be off the charts in either direction or no balance between nozzle holders. I am slightly north of 1,000 sets of injectors under my belt and so far all of these claims haven’t panned out. But who knows. If your car runs fine then keep up what you’re doing. For those who are more conservative or traditional, I suggest nominal PSI of 1650 or 1950 and new nozzles at 1700 and 2000 respectively and balance at +/- 25 PSI and new nozzles at the 75 to 100k.

For visibility, I am now down to the last seven (7) springs out of the 1,000 production run. Not sure when or if I will do another production run.

Just want to thank everyone !

As a heads up, and per my other thread, I am retiring my pop tester, website, as well as other services and products.

Right now I am now down to 29 OFV springs. This will truly be the end of them from me.

Please order through my website which is the easiest and fastest way to go.

Again, many thanks to the diesel community.

THIS IS IT LAST OF THE SPRINGS
 

This is it:

Down to 20 as pictured. Each tube contains one of my springs for the OM617 or OM616 family of engines. You will need the rebuildable OFV. The rebuildable type will look like a 14mm bolt inside a 17mm bolt. If your OFV does not look like this, and it has what appears to be a ball bearing sticking out of the side, then what you have is the non-rebuildable type, and it is aftermarket.

The spring is a common, R&R item as they wear out around every 100,000 miles. Please do not stretch or otherwise pull apart your current spring to try to "refurbish" it. This is a common hack which really does not work and may cause more headaches than relief.

Your OFV is on the in-board side of your injection pump, around the middle of the injection pump. It has one of your plastic fuel lines connected to it by way of a banjo bolt. The easiest way to locate your OFV is to follow the plastic fuel line. To remove the OVF, you will need one 17mm wrench. The spring swap takes around five minutes. You need to be careful to not drop your aluminum or copper crush washers since they will land in a spot which may be about impossible to see let alone get your fingers down into that crevice to retrieve them.

I have sold 1,000s of these springs over the years. Always two thumbs up, except literally one or two folks who claimed no difference. The latter may have had other engine issues.

Because of the overhead and production run costs, I am not getting any more made any time soon. Any time soon is defined as a possible 500 or 1,000 to be made which means years or never.

Therefore, if you want one of the last springs, order now. I am not reserving or holding on to any of them. I do not have any rebuildable OFVs. I have been asked this question literally dozens of times and there are literally dozens of folks lined up for one.

Shipping is only by USPS, Priority Mail. It comes with $100 worth of insurance and tracking. Please note: If the USPS says it delivers your box, but you claim you never got it, I will file a claim. BUT, the USPS will deny the claim and that ends the matter. Therefore, either provide to me the correct address and/or monitor your mailbox.

Last, postage has literally doubled in the last ten years. A small flat rate USPS box is about $10 bucks versus $5. PP fees inched up a smidge. Therefore, each spring shipped is $40.00.

If you buy more than one, you can deduct $10 off. As an illustrative example, you order three springs, the total cost will be $100 ($40 + $30 + $30 = $100). If you buy two, then $70 ($40 + $30 = $70). You can extrapolate the pricing for quantities other than two or three.

I do not come on site as much as I used to, but I check in every week or so. I will take PP for payment.

End Of An Era......
 

Those who fail to take this opportunity are missing out .

This is one of those keep it running well things, don't expect a huge boost in power .

When Mark (aka Greazzer) posted that he was getting out of the injector rebuilding biz,
I bought a set of Monark nozzles and had him install and balance them.
The old veggie car has never run better. I also bought one of his springs at the same time.
Get those springs while you can, folks!

A true gentleman and someone who has always done excellent work.
Mark, you will be missed!

Jeff

Did this upgrade two weeks ago and the motors runs much better, specially going uphill.

Hey Mark, I need one, the website is down

Ray

Yes- website has been down for a while now

Please Private Message me so I can give you my PayPal address

Update - down to 16 springs left. Please PM me to get my PayPal address. Many thanks again

Done! You had me at 'Performance Overflow' Send me 3 bushels :D

People run 45 psi (3 bar) no problems. I stretched the spring so tight the return line has only the injector return fuel going through it. And that's after I "de-stretched" it :P Sorry to Greazzer for going beyond his springs intentions

fuel overflow
 

There is a reason why the performance overflow valve still allows fuel flowing through the pump. Cooling, de-gassing and lubrication.


So i recommend you make sure you have fuel flowing out of the overflow valve again.

I want to try this on my '82 240D just to see what happens .

Application On 1982 OM616
 

I put this on my basic 240D's I.P. and it made the throttle response crisper .

You don't have much HP to begin with (67) so every little bit helps .

Update - bump

Still have some springs PM if interested

Thanks

Nice!

I can attest that this change alone took care of acceleration bogging. E

bump ... I have around a dozen left from this production run

Please see post 257 for pricing and shipping.

For the few folks who pinged me in the last few days --

yes, I have a few springs left.

yes, I will combine shipping.

no, I do not plan on any new production runs because the absolute bare minimum is 500 springs and I do not foresee being able to sell that many springs in my lifetime; therefore, once they are gone, they are gone.

no, I do not have any rebuildable OFVs for the OM616 or OM617 family of engines. The rebuildable OFV I have is for the OM603 / 606.

no, the OFV for OM616/617 is not interchangeable with OM603/606

Pricing and shipping info is noted above a few places. See post #257 for the most recent flavor. PM if you need my PayPal address. I will probably ask folks to please read post #274 if you ask me questions already answered.
