[Bazilisck311]

i was wondering if anyone knows a way to check for a vaccum leak in an 89 daytona ES 2.5L, without having to buy any guages or stuff like that..

thanx

My dad has this tool, I think it's called leak seeker, or something like that. It's a yellow box whith a flexible metal probe. you run the probe over all your lines , and the closer you get to a leak, the faster it beeps. It works for vacumm, AC, pretty much anything! Just out of curiosity, were you from?

try starting engine and very carefully use starting fluid and spray around the vac connections and lines and listen for rpm changes. when you find a spot that effects rpm suspect a leak. Be very careful starting fluid is FLAMMABLE so be light on the trigger. good luck

shelbycharger, im from upstate new york, around saratoga.
thanx for the tip slicksteve, but seems a bit dangerous for me, the only car i have, i dont wanna trash it just yet

i heard you can check a fuel line or something and if you hear a hissing sound, it means theres a vaccum leak, is this true?

[86shelby_charger]

I don't know about checking the fuel line...., but the first thing you might want to check is around connector just above the left side of your valve cover, all the vacumme lines run through it. This was a very common piece to leak as it's made of brittle plastic. If you look there and the connectors not there, then someones already bypassed it and did there own plumbing, check that too!!

cool, ill take a look at that, thanx shelbycharger

[Bazilisck311]

i jes took a look, i cant seem to find any connector, yet, i might not be looking in the right place, is just above the powerstering pump tank? when i find my digital camera (im not ver organized..) ill attach a picture of the area, and you can tell me...

thanx for the help

Hey Bazilisck, I just got my bro to sign up, he might be able to help you better than I can!!!! All he works on is 2.2's and 2.5's Anyway, I informed him of you problems with the engine, and he thinks he may have some solutions for you!!

[Bazilisck311]

alrighty, thats good. anybody that can help me!! im thinking the leak is somewere near the intake manifold, and it might have something to do with the leaking gas near the manifold. My Hanes manual says if you smell a gas odor, theres usually a gas leak near the carberator, and i smell gas in the car..

bear with me guys; up and comming mechanic

im gonna check that gass leak tonite, theres no excuse for leaving a gas leak around, its like throwing money out the window.

[86shelby_charger]

Gas leak!!!! that brings back memeories!! check you clamps!! I was bootin around one day and my fuel line came of were the rubber hose meets the steel line just as I stepped on it!! I was spewing gas all over my hot exhaust manifold!!! I was lucky.

[Bazilisck311]

lol, the only area iv checked and replaced so far is near the fuel filter (rear), all those were leaking gas, yeah i was getting like 10 miles to the gallon... now that i think about it, i did have to take of the exhaust and intake manifold off to get to the engine, wtf didnt i replace any of the clamps?? STUPID!!

your vacume leak could be the intake manifold gasket. if there was any damge done to it when you did your head gasket then it will leak. does your RPM fluctuate at all?

[Bazilisck311]

when i test for vacuum leak does rpm fluctuate? i havnt tested it yet, the rpms fluctuate badly when idling though.. I just found a gas leak near the intake manifold, i believe it might be the throttle body, but i havnt had daylight to ripe the air clearner assembly off and take a look.. According to my manual, all the symptons say i have a leak somewere near the intake manifold, so you might be right 'bout that, i dunno if it is a gasket, i think they gave me new gaskets when i had the top half of the motor rebuilt..
