Thread: Depression sets in.....

Hello,
Replaced the head gasket on my TD5 and now seems like it is running on 4 cylinders.......there is a tiny little bit of a tappet noise only at tick over would that a lifter isn't working ?? , taking the rocker off tomorrow morning to have a look, any ideas how to determine which one isn't working ?? I suppose i will have to remove the head again. will check the injector codes as well.
Any help would be great thanks.

Hello,
(again thanks everybody for the input) All injector balance is within 6 either side of minus all injectors okay disconnected all sensors except the crank sensor and plugged them in one at a time replaced the MAF with a very clean old one went much better, found that the MAP temp is working but the pressure is not so will have a look at that now, the thing which I am wondering is that I put 5w-30w is this to thick ??? instead of my usual 0w-30w anybody ????? would this make it nosily at tick over remember that it hasn't run in about 4 months.....so not used to the sound anymore..
