Thread: why is my 350 makeing that noise

Tweet

I have headers and did away with all of that. Converter bolts o.k. No shavings in the oil ...nothing around the converter, will leaking exhaust gaskets sound like that?..It's as if you are taking a a rachet and beating it on the block ....oil levels are good...Chip

converter ok, no shaving is oil pan, can it be exhaust gasket leak?

Exhaust leaks make popping noises, especaially under deceleration. Is the truck drivable? Run it up to 2000-2500 and let off the gas and let the truck coast. It will pop quite a bit if it has a bad exhaust leak.

Runs great....I will try that next..I am going to try the gaskets this weekend..Chip

My brothers 84' VW Rabbit GTI has an exzaust leak in a gasket or a crack in the manifold and, when driving down are road you can hear small pops that almost sound like a tick, When the car was louder ( shot exzaust ) it sounded like a nascar backfiring during deceleration, I thought it was kinda cool cause it is a retired ice racer. Of course the car has the doors from 3 other rabbits ( 2 fronts and the decklid ) and the parts from a GMC truck ( cold air intake ) and an old colman furnace casing ( Hick floorboards )
