1988 e250 van runs but loses compression upon acceleration has a "POOFING" sound. Could this be headgasket? Does not knock, no steam coming from tailpipe, no oil in water.

Do you
have the same problem?

Are you sure the catalytic converter isn't plugged? As far as the headgasket, you will need to check engine compression to determine if there is a problem. Based on the sound it makes, it almost sounds like a plugged converter. Check that and let me know what you find.

Check to see if there is a lot of pressure from the tail pipe. As far as the noise, could it be coming from that area? If you want, remove the O2 sensor to allow additional flow for the exhaust to see if it changes anything. I hate to say disconnect the converter because the bolts are usually rusted and a pain if you need to reuse them.

I have located the czatalytic converter and it is welded on, no bolts or hangers found. Can I take my reciprocating saw and cut it from under the van or knock several holes in it with my drill?

As far as the o2 sensor it is intact located just before the catalytic converter. Should I disconnect that before attempting to remove or bore holes in catalytic converter?

First, it is federal law that you have a functional catalytic converter. What to do is remove the O2 sensor so there is an escape for exhaust if the converter is plugged.

IF YOU JUST CAN'T MAKE IT GO

INNA BIND (RIGHT NOW)

JUST TO GET YOU TO A MUFFLER SHOP

I WOULD THINK TAKING WHATEVER MEANS IS NECESSARY WOULD BE OVERLOOKED!

RUNNING IT AS IS, VERY LONG WILL CAUSE ENGINE DAMAGE

LIKE JACOBANDNICKOLAS SAID THERE'E A O2 SENSOR SOMEWHERE CLOSE, SO DO NOT MESS IT, OR IT'S WIRES UP!

SOME MUFFLER SHOPS WILL CREDIT YOU SOME, ON THE OLD ONE. MOST CONTAIN "PLATINUM", AND EVEN "WORTHLESS", NOW ON YOUR RIG. IT STILL POSSESSES VALUE. THAT'S WHY YOU HEAR OF SO MANY COMING OUT OF THEIR HOUSE/ STORE/ WORK, ONLY TO FIND THEIR RIG IS REALLY LOUD. SOMEONE HAS "JACKED" THEIR CONVERTER WITH A BATTERY OPERATED RECIPROCATING SAW. TO GET THE $$$!

ABOUT A YEAR AGO, HERE, AFTER HUNDREDS TOOK MISSING. SOMEONE CAUGHT THE "POOR FELLER" IN THE ACT, IN A PARKING LOT."SOMEONE'S" BUDDIES WERE PRESENT TOO!

IT WAS SORTA AMAZING, HOW MUCH THE FELLER HURT HIMSELF, TRYING TO FLEE!

IT'S ALSO GONNA MAKE SOME BIG TIME RACKET WITH THE EXHAUST SYSTEM LOOSE!

IF I WANTED TO DISPLAY IT WAS IN "DISTRESS", LOOKING FOR IMMEDIATE HELP.I'D ONLY CUT THE ENGINE SIDE LOOSE, AND MAYBE WIRE THE REST OF IT OUT OF THE WAY SO IT COULD AT LEAST BLOW/ FLOW FREELY FROM THE ENGINE SIDE

GET 'ER FIXED REAL SOON. THE RACKET WILL BE REALLY ANNOYING, AND DRAW MORE ATTENTION TO YOU!

OLDER STUFF, YOU COULD MAYBE GET AWAY, WITHOUT ONE, IN A REGION THAT IS NOT CHECKED. BUT WITH NEWER STUFF, UNLESS THAT DOWNSTREAM O2 SENSOR IS WORKING RIGHT, YOUR VEHICLE MAY REMAIN IN "CLOSED LOOP" PERFORMANCE AND ECONOMY MAY SUFFER DRASTICALLY. SO YOU PROBABLY JUST NEED IT PUT BACK LIKE IT WAS DESIGNED!

GOOD LUCK. MAY THE FORCE BE WITH YOU!
