98 12 valve slight ticking when cold
Ok i just noticed the other day while driving i have a slight ticking noise.. once the temp needle starts to move it goes away.. i dont hear it at idle only as slight throttle.. and after i get up to about 1500 rpm it goes away.. so basically i only hear it from 1000 ti 1500 rpm.. it sounds like its coming from the back of the engine near firewall.. i did adjust the valves about 2 months ago and replaced lift pump.. any suggestions? Thanks!

OFV .. the return line is ticking .. I would make a bet that your fuel pressure is lower than 20 pis @ idle too... :c:
|
I jus replaced the overflow valve with an adjustable one i checked it 2 weeks ago and it was at i think 23 or 25 psi at idle and 30 psi at 2500rpm
|
Lift pump is ticking then .. if pressure is ok .. drive it :c:.. mine ticks too
|
But what makes is only do it when engine is cold? And why only at light throttle not at idle or heavy throttle? It sounds like its coming from the #6 cylinder valves... like right on the other sode of my firewall lol
|
cold parts .. more space until they warm up and expand ...:tu:
|
Yea i gotta check it out lol
|
try adding some lucas to your oil . I added 1 qt of the Synthetic to mine and its a bunch quieter now :yeah:
|
You mean lucas oil stabalizer? Or just a quart of regual lucas sytnthetic oil
