Unless you have done a few with a torque wrench and have a feel for it, I would not recommend trying it without a torque wrench

0.12*750= $90

That's not a bad savings

No, not at all. As you see, my mechanical talents are poor. Had no knowledge of not using any type of torque wrench on injectors. "Mr. Badwrench" lives !!!!! lol

Saving my pennies, Tyler. See ya soon.

Well, another 508 miles on 12.217 gallons. Even with hills going up to Albany, NY and Western Mass., I still average 41.7 while trying to stay at 55-60, but no higher than 65. No A/C used at all.

New tires, new alignment, new CV shafts, new timing belt, new air filter, fuel filter changed 5k miles ago, drained every 1000 miles. All unecessary weight removed from trunk/passenger area.

Guys here with more miles than mine still are getting 4-8 and more mpg. I drive any slower, those old folks on the electric scooters will pass me.

Any other suggestions? (And it's anatomically impossible to do THAT!)

Thanks again.

41.7 isn't that bad.
But I wonder why you cant get higher.

I'm driver no slower than 65 in my TD and I'm getting a solid 44..

Every car is different I guess

Amen, beggars can't be choosers. I agree. But I had a high of 55.9 driving 55-60, and averaged 45-48mpg, and 43 mpg doing 70-75.

I burn very little oil, so compression should be good (

). I wonder if injectors with 222k miles could cause a drop in mpg.

I'm not good with a wrench, and don't want to spend a ton of $$ having something done with no improvement.

Some of you guys here are amazing with these VW diesels. And Tyler has given me tons of info with PM's.

So I wonder if and how I can improve my mpg, besides going to get my IP "Gilesfied".

And if that gives me great mileage, as many here have said (and I'm not doubting), maybe my IP is wearing out?

Thanks again. Stay safe, stay well.

search for facet fuel pump on ebay. those little pumps are great for getting rid of bubbles in the fuel lines. which will increase the life of your pump, and give you smoother power & easier starting... nothing like getting a worn pump rebuilt though!

Will this improve the mpg? I add stanadyne or power service diesel conditioner every fill up for lubrication of the IP.

Air bubbles in the system can affect mpg? If so, that much?

Thanks....SS, SW.

if you have air going into the pump, the pump won't be able to maintain the right internal pressure, so the dynamic timing is affected. those little pumps really help in that the pump always has enough fuel going to it. it also helps with fuel filter changes :wink: and can even extend the life of a fuel filter!

Learn something new every day. Thanks.

But if this is the problem, why now? Time, age, ULSD, etc.?

And you would rule out injectors being the problem?

I'll check Ebay tho,thanks again.

Stay safe, stay well.

i'd get the pump & the injectors... at least new nozzles, as they are a maintenance item such as the timing belt. the damage caused by a faulty injector is pretty bad! burnt pre-cups, holes in pistons/head, etc... if you're tight on funds check out prothe's site www.vwdiesel.com i bought a set of his TD injectors and they seem to be running just fine (installed around march of this year - about 5000km on them so far). i had the GTD's installed before, and they have a noticeable power increase, but all i noticed from going to his injectors were a slight power decrease.

Thanks. As I am saving my pennies to get my IP "Gilesfied", I plan on making a trip to Toronto for a few days and let him and/or Tyler do the pump, and buy Tyler a few beers I owe him...lol

Old injectors (as I guessed) may be compounding the IP situation you mentioned. This car runs great, and as much as I want a new one, I wanna get as many miles as I can out of it. And I have to have a clutch in my new TDI. That auto/shift in the '09 isn't the same, IMO.

Since I added the Recaro interior I bought off the Vortex, it's even more fun and comfortable to drive. 20 hp (as I am told the "Gilesfied" pump may give me), I think may be more than enough to keep up with traffic.. lol

Not looking for an Indy cruiser (and I am still amazed you guys get so much hp out of these things), but something just a little more peppy. And spoiled with great mileage that I want back..

Thanks for the input from all.

Stay safe, stay well.

Many Facet fuel pumps. Any for VW diesel or are some universal?

Maybe this is a big reason my mileage dropped.

Checking over car today, noticed smoke from oil fill on valve cover. As I took it off, I was given a hand by abnormal backpressure. So it seems a lot of back pressure is building in the engine, to a point where it pushes my oil dipstick up.

Seems the hose off the valve cover to the air intake is clear. I do not recall this car having a PCV/EGR valve. So I do not know where the back pressure can be coming from.

Again, I leave it to the experts. Fire away. Thanks in advance.

Stay safe, stay well.

Sounds like you could have some blow by. :? If you have the injectors removed for rebuild, you may want to do a compression test at the same time.

Thanks, Cyrus. Went to a pal of mine who is a heavy duty diesel mechanic (not a VW wiz like the guys here). Called VW who said there was some sort of PCV type valve that goes on top of the valve cover, at a cost of 80 bucks.

I bought the car with 182k, and have not had a problem with anything till I posted the mileage loss. Obviously and hopefully, this will solve the back pressure/ mileage problem.

As I posted, I'm not mechanically inclined. And I can take a good guess that the PO took it off, and didnt want to spend the money to replace it. When I bought the car, the only thing was the hose that goes under the air cleaner was connected directly to the valve cover. As bad as I am with cars, I think I would have noticed that valve there.

Thanks to all for the info and the replies. Hopefully this will correct it, and I'll get my 45+ mpg back.

Stay safe, stay well.

for tightening injectors you dont really need a torque wrench...

I actually got a little light headed when I read that........... :shock:

Broken injector boss's are going to be showing up now!! Way to go!! :?

Seriously though. I will NEVER not use a torque wrench again on a injector.

NEVER!
