Fuel Injectors o-rings..

[bimmer94525i]

94 525i. How difficult is it to replace injector o-rings? How many are needed? Also, fuel feed and return lines may need to be replaced. Any diy links? Im trying to find out where the gas smell is coming from during cold weather. Speaking of cold winter weather here in CANADA, what engine oil viscosity do you recommend. Thanks in advance.

never done an M50 but you need 2 rings per injector (i.e. 12 in total)

If you need some rings i have some. i got some with my new injectors not knowing they came with them already. would rings from a v8 work?

Thanks for the offer but I don't know whether same o-rings are used on in line 6. Maybe someone here knows.

Umm, FAIL!

The people on this forum are pretty easy going, but you have committed an unforgivable bimmerforums sin.

yea never use v unless it has an 8 after it. offer stands if you find that they will work.

honestly, based on this sentence alone, I don't think you should be under the hood of your car.

Hey cut him some slack. Maybe the PO did a transplant and installed a V6 in the BMUU.

OOOOOOOOOOOOOps!! I meant in line 6. My mind somewhere else, my mazda mpv. Regret.

Those o-rings are used on virtually every BMW model (same as the oil drain plug for example). Checked with ETK and they are used on most E30, E36, E46, E34, E39, E32, E38 and E31 models.

For E34 specifially the same o-rings are used on
518i M40
518i M43
520i M20
520i M50
525i M20
525i M50
530i M30
530i M60
535i
540i
