    EA81 Tick...

    in Old Gen.: 80's GL/DL/XT/Loyales...

    Posted · Edited by tundrabrat

    You guys are awesome! I threw some edelbrock zinc additive in there and my local shop has a sale on Delo 1 gal ($19.99) so I'm picking up 2.

     

    Engine is very happy and knowing that the cam will add to the noise makes me realize it is really very quiet... Like a happy sewing machine... a torquey sewing machine.

     

    Thanks to all for great advise!

    Sounds like I created my own luck on this one.

     

    I haven't used a zinc additive before, what am I looking for when I go to buy. In addition to protecting the internals, will this assist with the noise.

     

    In regards to the heavier oil, I've been running 10-30w from what I've read... But you say 10-40 is factory, is that the consensus from other users?

     

    Sounds like I'll start putting together another short block in the mean time sans the torque grind.

     

    Thanks for the assist.

    I've seen EA82 threads regarding the Tick Of Death but I haven't found any specifically focused to the EA81.

     

    I have a freshly built EA81 (with Hydro Lifters) with a rebuilt oil pump and a torque grind on the cam.  I have what looks to be great oil pressure however I have a tick that always seems to be there though it changes intensity.

     

    I was careful to check specs while of rods and bearings during the build and I have adjusted the valves and they seem to be well seated.

     

    I'm just over 1,200 miles on the rebuild and did the final head re-torque fresh oil change with 10-30w this weekend.

     

    I have seen quite a bit about replacing the oil pump gasket or doing a rebuild on the oil pump... my question is if the pressure is good, what does this accomplish?

     

    Do I need to replace the lifters... would a torque grind cam require new lifters?  If one or more lifters were bad wouldn't there be some play?

     

    Sorry for all the questions but I would prefer to fix this right and have an understanding of the reasoning behind the repair instead of throwing heavy oil in  (15-40 etc) and masking the problem.

     

    Thanks again of time!
