Licensed to kill Posted October 6, 2020 Share Posted October 6, 2020 I'm not at all familiar with that engine but sounds like that rocker isn't getting oil. If it is oiled through the push rod the rod could be plugged. Whatever pool gallery feeds it must be blocked. I'm assuming that the valve lash is set correctly.

fjh Posted October 6, 2020 Share Posted October 6, 2020 Does it have a fuel pump on the right side or does it have separate unit pumps ? Quote Link to comment https://www.bigmacktrucks.com/topic/64482-ticking-sound/#findComment-461995 Share on other sites More sharing options...

fjh Posted October 6, 2020 Share Posted October 6, 2020 If its E7 the lash adjuster and pushrod could be compromised Quote Link to comment https://www.bigmacktrucks.com/topic/64482-ticking-sound/#findComment-461997 Share on other sites More sharing options...
Vicki Posted October 6, 2020 Author Share Posted October 6, 2020 Was told the push rod was changed. Still ticking. They are pulling the head to see if it's a valve.

They are pulling the head to see if it's a valve. Probably not a bad idea. I had a 3406 CAT in an '87 LTL 9000 that had a tick. Found a bent push rod, replaced the rod, set the lash and the tick persisted. I was taking the truck to a mechanic friends place (12 miles away) to have him check it out and on the way it dropped the exhaust valve in the same cylinder that the push rod was bent and put the rod through the block. The tick went away 😜 Edited October 6, 2020 by Licensed to kill Quote Link to comment https://www.bigmacktrucks.com/topic/64482-ticking-sound/#findComment-461999 Share on other sites More sharing options...
Mackpro Posted October 6, 2020 Share Posted October 6, 2020 If ETECH. Could be “H ring” in block that holds and alings the roller lifter . It can be dislodged and can cause roller lifter to cam alignment issues Quote Link to comment https://www.bigmacktrucks.com/topic/64482-ticking-sound/#findComment-462019 Share on other sites More sharing options...
