Lift pump tick or not?
 

I have a tick that comes from my engine. It will come and go, its consistant with RPM But i hear it more @ idel. My truck has no oil leaks, and the Kdp has been adressed. I am almost positive that the noise is either comming from the p7100, or the the lift pump. Just thought i would ask if the lift pump tick common in the 12 valve could be intermitient. I tried putting a pice of wood up to it to listen but the trucks so loud it sounds basically the same everyplace.

it is very possible the stock lift pump, at least from what all ive been told. good luck gettin it fixed

bio fuel may quiet it down enough to be able to locate the ticking.

yup, mine does it too, lift pump makes the sound , all it means is the cam lobe is worn nuthin to worry bout mine does it all the time then sumtimes it wont, kinda annoying i know but oh well no big deal

could be the valve need adjusted i know mine has always had a tick never could figure it out and now that i have an airdog i know for a fact its not coming from the lift pump

SORRY I DIDNT READ YOUR SIG
:argh:

push in your primer bulb on the lift pump, if it quiets down or goes away, there's ur problem.

Alright Good deal, next time i hear it tick, i will prime it and see if it goes away. i have just adjusted my valves about 10,000 miles ago

yeh mine ticks too.. but i only got 180,000 on the truck.... mine only comes on when i turn the A/C on.. weird:humm:
