Vacuum line clarification

[boxfix]

I had a similar vacuum leak and SAI that would not reset.

Trying to get the 986 smogged in CA.


I had multiple vacuum leaks.

My vacuum reservoir was leaking. I put a vacuum hand pump and gauge on it with the reservoir in place and used long needle nose pliers to get the hose off and connect a test hose directly to the canister. It would not hold vacuum, but the replacement reservoir would hold vacuum.

New reservoir was like $22.

[you have to take the alternator out to reach the reservoir for R&R. I just put the second reservoir in the corner of the engine compartment and left the old one in ther unhooked from the vacuum system.]

I also had the at "L" not in the hole in the rubber part. I used a brass barbed fitting in the rubber manifold and high temp silicon tubing to connect the check valve.

I replace every bit of rubber hose I could with 3mm silicon hose.

I then inserted a vacuum gauge in the system with a "T" fitting. The manual says you should get from 12 to 19 inches of vacuum at idle. I had about 17.

Then all the "MONITORS" went away. If you have a Durametric you can see if the monitor pass or fail.

Be happy to answer any questions or PM me.
