HEY GUYS IM NEW TO THE SITE, WELL I SAY NEW I'VE BEEN LURKING AROUND SINCE I BOUGHT MY 924S BUT FINALLY SIGNED UP TODAY. MY MOTIVATION TO FINALLY SIG UP IS I NEED HELP JUST BOUGHT MY CAR A FEW MONTHS AGO AND IVE BEEN WORKIN ON IT EVER SINCE PUT A CLUTCH IN RUN FINE HAD A BLOWN HEAD GASKET USED BLUE DEVIL AND FIXED BEAUTIFULLY NOW AT AROUND 30MPH/3000RPM THE CAR STARTS LUNGING TERRIBLY. DID IT YESTERDAY AND I LIMPED HOME (AROUND 1/2 MILE) WHEN I FINALLY GOT HOME THE CATALYTIC CONVERTER WAS BOILING SMOKE AND SO WAS THE MUFFLER??????? THE CAR STILL HAS NO THERMOSTAT IN DUE TO THE BLUE DEVIL I JUST USED. IM STUCK AND DESPERATE AND JUST TO NOTE USUALLY ID NEVER USE A QUICK FIX LIKE BLUE DEVIL BUT IM IN A BIND SO PLEASE NO CRITICISM ABOUT THAT

IT MIGHT BE THAT THE HEAD-GASKET FIX HAS LEAKED INTO THE EXHAUST AND IS BURNING UP THE CATALYST. SOMEONE RECENTLY POSTED A PICTURE OF THEIR MUFFLER WHICH BURST OUT THE SIDES MOST LIKELY BECAUSE THE CATALYST CAME APART DUE TO A SIMILAR CHEMICAL. YOU MAY BE LIVING ON BORROWED TIME AS THE CAT IS NOT SUPPOSED TO SMOKE. FIXING THE HEAD GASKET AND LIKELY REPLACING YOUR CATALYST WILL BE NECESSARY SOON.

WE HAVE NO EMISSIONS LAWS IN SC SO WOULD JUS TAKING THE CAT OFF HURT? IM A BIG CORVETTE GUY AND WE DONT REALLY USE CATS LOL. THE MUFFLER SMOKE WAS NO WHERE NEAR AS BAD AS THE CAT

YOU CAN RUN A STRAIGHT PIPE NO WORRIES BUT YOU SHOULD REPLACE THE HEAD GASKET AND FLUSH THAT JUNK YOU PUT IN OUT

C4ORCE

YEA I PLAN ON IT JUST AS SOON AS I CAN. IN THE MEANTIME ARE THEIR ANY OTHER SUGGESTIONS? THIS WAS MY FIRST GUESS TO BUT JUST WANA KNOW IF THERES ANY OTHER POSSIBILITY'S OH AND ITS ONLY UNDER ACCELERATION NOT WHEN IM OFF THE GAS

Paulyy

I AGREE, REPLACE THE HEAD GASKET AND FLUSH THAT **** YOU PUT IN.

I agree replace the cat with a straight pipe (cheap fix) or if your REALLY in a bind with funds I have seen guys cut a 3" square hole in the cat and use screw drivers etc to gut it COMPLETELY out then weld the hole back up. Not easy by even cheaper than having the thing replaced with a couple of section of pipe from autozone. It should only take 2 they cost like $6 each.

The head gasket job is one I have never done on these cars so can't speak to that. Whatever you do do not run it again until you get it replaced. Do you have the online links to Porsche shop manuals? They are free PDFs.

DOES ANY ONE KNOW THE DIAMETER OF THE EXHAUST PIPE SO I CAN GET SOME ON THE WAY HOME? LENGTH OF THE CAT WOULD BE NICE TO

C4ORCE

IS IT REALLY THAT BIGA DEAL??? LOL sorry the computer at work is always set to caps and i forget to take it off. whats your opinion cat 2?

EMPmotorsport

I Agree.
get rid of the insta head gasket fix crap, and replace it right. flush your system and remove the cat then you will be in much clearer waters

as far as the gauges all going nuts.... Id look at a grounding issue check all your grounds check battery contact ect...
