[DML] vacuum leaks

["Warren Wallingford" <warren@xxxxxxxxxx>]

I've noticed a couple of postings concerning bad idle and performance due to suspected vacuum leaks.  This is a constant topic of conversation with owners and mechanics that call DMCH for tech help.  The intake of the Delorean's PRV can be tough to seal.  There are a lot of places for it to leak, some of them obscure.  I talked recently with a shop that had done what I considered to be an extraordinary job of finding a hole in the system.  By clamping of hoses, they had traced their rough idle to a crack in the rigid vacuum line running forward from the right side of the engine to the front of the car to feed the brake booster.  

The lesson is that as the car gets older, there will be different and new places for it to malfunction.  Let's not forget that engine vacuum puts the power into the power brakes and pulls the flaps that direct hot and cold air from the dash.  The hot water valve is modulated by vacuum.  All of these places are potential trouble spots whose only noticeable effect is on engine performance.

By the way, we have those vacuum lines in stock. Part number 100416, $15.49.
