new car big problem

[arnoldx3]

Hi i have recently got a vts for a good price as the bodywork isn't great and it had a missfire so i bought a new coil pack but i found out today it not the coilpack which is the problem .
after doing a compression test one of the cylinders was reading 0 the other three were reading 220 psi how much damage do you think has been done i look forward to hearing back from you

[Dom_G]

depends on why there is no compression

[arnoldx3]

i was told that if any valves are bent it would then loose compression

[mc_neat]

valves arnt expensive..its the job its gonna cost..or if u have a haynes manual u can diy it??

[arnoldx3]

do you think i have got lucky and just bent a few valves its strange how it just went on one chamber though

[deesvtsT]

sounds to me like a bernt out valve not bent have to take the head off and have a look

[1-1dicky]

+1 i agree with a burnt out valve

[arnoldx3]

thanks for all of your help could it have anything to do with a FSE Fuel Pressure Regulator which was fitted if it is a burnt out valve that means it should be fairly cheapish to fix then

[deesvtsT]

could be that the fse has added to much fuel and bernt the valve out the valves are cheep its the time it takes that is the problem if u doing it DIY bonus if u not still going to cost a bit garages are expencive try to find someone a mate or someone to do it it will be cheeper
