whatever u call it blown or broken gasket i just gotpacesetter headers installed ever since its been vibrating my chairlike crazy and when its in reverse it makes a sound like its hittin metal then 2 days later i broken a gasket would the gasket be the problem to the vibration what does it do when broken i got it flushed the same day 1994 3.4 camaro

 

its an automatic when it revs out to shift it makes that metal sound

 

Is there a clearance issue with the headers -- are they rubbing some other metal somewhere, or not fully secured?

I would take it back to where the work was done. What gasket blew?

 

blew a headgasket and they did tell hat it was rubbin against something but idr

 

just made the call its rubbin against the crossframe all forgot they didnt put a cat converter they put a test pipe on it aint a header gasket its a head gasket on the cylinder heads that part was my fault cuz i put cold water in the anti coolant with the car off and engine hot but i was j/w if thats the cause of all the vibration

 

So what's the solution to the rubbing on the cross-frame?

 

the headers r rubbinon the crossframe does anybodys headers rub on the crossframe

 

A blown head gasket would cause the vibration and rough running.

 

can anybody tell me what parts i will probably be replacein cuz i drove it for 3 days with a blown gasket i barly pressed the pedal though cuz that annoying vibration

 

Keep driving with a blown head gasket, and it is going to get worse. Eventually enough coolant will get into the cylinders to cause hydrolock and somecostly parts, like pistons, heads, or connecting rods,could break. You need to get yourself a service manual and start reading it. BTW, never add coolant to a hot engine, it can cause damage.
