Default ALERT! So Cal Leaky Injector Pump Special,

Since so many posts have appeared on leaky injector pumps, Harvieux over at Wild Rose has decided to help out fellow TDI club members with doing an R&amp;R of upper and lower seals on their Bosch VE4 pumps.

For $120 US, he will change out the upper and lower QA seals on your pump and VAG-COM it into spec. The price of this service is $120 and include parts and labor. This will fix the leaky pump problem 90 to 95% of the time.

Please be aware that if you have had a leaky injector pump for some time, diesel fuel may have leaked on your waterpump/cooling hoses and that they may be in need of replacement also.

Harvieux can be reached at 1 310 721-4867 in Fullerton, CA.

Seriously, after visiting his shop and seeing so many clean looking TDI's, I kind of feel like my '96 Passat was dragging down the values of the other prime real estate on his lot.

This guy is a specialist, mostly TDI's is all he wrenches on, I think he could work on them blindfolded and still do a good job.

Seriously, with Low Sulfer Diesel coming our way in 2006-7 here in CA, I am certain you will need a new set of seals. Much cheaper to do it up front than wait for it to go bad, wreck a bunch of radiator hoses due to diesel fuel leak in the process and then have to pay to fix THAT problem also.

I didn't have that option, I just bought my B4 Passat and the previous owner did the damage to my hoses. Preventative maintenance pays on a TDI.

Default ALERT! So Cal Leaky Injector Pump Special,

Yes!!!!!!!! Harvieux is the bomb!! I had a leaky pump a couple years ago and he hooked me up with a extra pump he had laying around the shop. Mine was leaking everywhere not just at the top.

I live in Florida so I did not have the option of driving over there. He mailed it to me and I had it on the car in 3 days....... Problem solved and never leaked again.

Great place and easy to deal with. They "Really" know there stuff.

Default Injector Pump Seal Replacement guru near Salinas/Santa Cruz?

I have the infamous injector pump seal leak on my 97 Passat.

There's no way I'm trying this myself. I have the seal kit, but the various threads, primers, didactics, and photos just scare the crap out of me.

DOES ANYONE KNOW A SOUL BRAVE ENOUGH TO CRACK INTO MY INJECTOR PUMP WHO HAS DONE THIS BEFORE?

Any place within 100 miles of Salinas, Watsonville, Santa Cruz will do.

Thanks,
Wendell

Red face Injector pump healed

Due to car going to be left in long term parking 120 miles away and no time to replace seals, I had to do a quick fix on a Leakey pump.
To the fuel tank, I added one bottle of engine oil seal restorer and a quart of ATF for lubricity. Then topped off the fuel tank with number 2 diesel.
Headed out, arrived at parking location. When I returned, five days later car started right up. The pump had not leaked down like it did in a few days at home. Now two weeks later the pump is staying dry.
Due to the leaking pump, I had to repair the coolant reservoir return hose (1J0121109C) and will replace it later.
Not a proper fix but it worked for me.
Regards

Default Short lived "fix"

Pump is leaking now worse than before. Ordered the kit and the two viton seals. The seal replace video is great. I learned.. With top off you can see when the pump is "on cam".
Need to finish replacing the front wheel bearings first. 190k on the clock.
Cheers

I believe those products are solvents that cause the rubber to swell. They eventually cook out and the rubber shrinks again, probably to a smaller size than it was.

Same thing happened years ago when the new D2 formulation was mandated. People blamed the low sulfur but it was actually the removal of the aromatics from the fuel that caused the leaks.

The same swelling effect can be accomplished by dumping ATF in your fuel too, but as was mentioned before the longevity of any of these is limited.

Just have the pump resealed and be done with it.
