installing a vaccum gauge help.

[[email protected]]

i got a vacuum gauge and want some help in finding the right vacuum hose to connect it to pics please ka24de im really new to this stuff

Hooked into the brake booster line will work fine. Just need to measure the size and get an adapter

i have no idea where that is on the ka24de i searched it but i am unsure

One one line goes to your brake booster. It gives it vacuum aka power brakes. If you get an inline adapter with fitting all you need to do is cut an inch of line out, put this in the line, and put the gauge tube / sensor there.

thanks alot for resp so fast i appreciate it

I would have got off the intake manifold. You are trying to measure engine vacuum right?

yes the engine vacuum

i tapped the line that i taught was the vacuum but was the egr line i cant find the vacuum line to tapp off i dont know what it looks like any pics ka24de

Mine's torn down for a rebuild right now. Look for a rubber line that is very flexable and feels smooth. Should be one on the intake manifold.

I want to know why do you have a vaccum gauge? to see how fast your not going?

A lot of your posts seem like you don't think things through.

Maybe he wants to see if he has any leaks. Maybe his throttle body isn't opening all the way and he never gets to 0 vacuum.

A vacuum gauge has absolutely no correlation to speed. I can be going 100 mph and have 30 lbs of vacuum.

I use a vaccum gauge all the time but only for diagnosing purposes not on the Apillar like I think the OP is referencing.....

i just find it strange that people always want to see the vaccum a NA car is making all the time because I only use one when I sense a idle problem or hesitation

sorry for the blatant first post but i just need clarification

yeah, i smell rice

A boost/vacuum gauge makes sense

but a only vacuum gauge....

I use a vacuum gauge, but on my vacuum res can. The reason for my use is because I was having braking issues when I swapped heads and cam.

vacuum gauges areee sort of "poor man's" fuel mileage indicator when vacuum is low, you are burning more fuel.

heres the chart

The following readings DO NOT apply to turbocharged engines. All readings are inches of mercury (in. Hg.).

ENGINE STATE VACUUM GAUGE READING INDICATION

Steady idle (800-1200rpm) Gauge steady, 17-22 Normal & healthy

Steady idle (800-1200 rpm) Intermittently drops several needle divisions Sticking valve or broken valve spring

Steady idle (800-1200 rpm) Steady, low reading, 8-14 Small vacuum leak or valve timing off; could have low compression/worn rings (verify with a compression or leakdown test).

Steady idle (800-1200 rpm) Steady, low reading, under 8 Vacuum leak (check brake booster, vacuum lines, etc.)Idle (800-1200 rpm) Needle drops sharply on a regular rhythm Burnt valve, or a valve with clearance too tightIdle (800-1200 rpm) Needle drifts up & down, along with rpm drift Mixture off or small vacuum leakIdle (800-1200rpm) Vacuum gradually drops Excessive exhaust back pressure (plugged muffler or catalytic converter)Idle (800-1200rpm) Intermittent fluctuation Ignition miss; sticking valveIdle (800-1200rpm) Steady, above 22 Ignition timing may be too advancedOpen & close throttle quickly Drops to about 2, jumps to about 25 Healthy engineOpen & close throttle quickly Drops to 0, jumps to about 20 May confirm worn rings (especially if idle shows only about 15-20) Verify with a compression or leakdown test.

engines with performance camshafts tend to read lower vacuum. readings are also lower at higher altitudes; the rule is approximately 1 inch of mercury for every 1,000 feet of altitude gain.

Everything else aside, a high vacuum reading tends to indicate a healthy engine.

its the science behind it is honestly what i like
