Fighting the dreaded [B] BLM's [/B]

[Royal-T-Ltd]

In my fight to tune the beast and lower the Block Learn as well as pass emissions - I have noticed I've previously changed all my vacuum lines except the ones to my EGR solenoid and valve. When I looked at these closely i noticed they were dry rotted So hopefully I have found the culprit to my BLM blues...I also found a bad check valve to the charcoal canister. Getting back to the point - has anybody noticed the small, almost fuel filter looking, filter on the back of the EGR Solenoid. Does this ever need replacement?

took mine apart when i was fighting high BLM'S. filter was that 'spongy' foam stuff, washed it with laundry soap/water, dried it out,and re-installed. seems ok, lol with your BLM problems!

If the check valve under the FPR was toast, the EGR selenoid valve may be bad. Remove the sponge filter, apply vacuum with the mity vac, it should hold vacuum when you put your finger over the nipple. If it makes a farting sound, its probably bad.

I'll give you this tip.. put a piece of blank gasket material over the TB under the vacuum distribution block. your BLM's should go under 128 to about 120. If so..then you have one of the lines with issues. If not.. look else where for your leak.. like headers, plenum gaskets, IAC gaskets, MAF, O2 sensor, etc

HTH.. good luck..its a pain to get them rite..but once they are.. aww... you'll feel relieved.
