cylinder 3

so i went and looked at a vr4 today and the guy said he had the motor replaced. but there is something wrong with cylinder three. so my questions to you guys and girls is what do you think it could be.

btw the new engine has 50k on it so i doubt its a piston or rings but ill take your opinions. thanks

does it knock?

ask the owner to do a compression test (on all cylinders) and leak-down test on cylinder #3 in question.

how does he know something is wrong with cylinder 3? is it getting spark? fuel?

Guys, something is wrong with my car, what could it be?



You need to provide details.....

Offhand, it could be any of these things

Lash adjuster
burnt valve
broken valve spring
rocker fell off
piston rings leaking
bad head gasket
spun bearing
worn bearing
broken wrist pin
broken connecting rod
broken ring land / piston
bad spark plug
bad coil
bad spark plug wire
bad ecu
bad wiring to the coil
bad fuel injector
clogged fuel injector
bad wiring to the fuel injector

okay well ill tell you what i do know about it. the owner had 2 vr4s one with good motor bad body and one with bad motor and good body so he put the good motor in the good body. supposively it ran fine when it was in the last car. the guy that did the engine swap supposively had no idea what he was doing with this car.

and linebckr: the guy that put the motor in told the owner that there was something wrong with cylinder 3. but he wasnt very clean. and the owner isnt a car guy so it just kinda went over his head im assuming.

but lets say i do a compessions test and it comes up bad. what all could that be?

and talskiny: the reason i was alittle vage was cuz i wasnt sure if vr4s had a history of problems with specific cylinders.

well any ideas or suppestions would help. thanks
