Full Synthetic top end noise?


Cam'ron

Recommended Posts

I am thinking of making the swap to synthetic at my next oil change (maybe Mobil 1 again or even Royal purple), question is anyone else with the L67 or L36 i guess get any extra engine noise after that swap? On my 03 with the 3400, when i swapped to Mobil 1 my top end noise became almost unbearable and i swapped it out after merely 2000 km of driving.

stock... hmm whod'a thought :lol:

I've run ACD PF52 on everything since I got my first W-body, after the second oil change. the ACDs are fine, btu WIX and pureolater are excellent choices too.

i run wix whenever possible, but you cant always get ahold of them up here, but if not wix ACDelco PF52. any oil filter guide will show a different one(for the 3100 anyways) but the 52 is bigger and will work perfectly(cost the same most of the time too). found this out after i did an oil change on my dads 96 tahoe 350 and back to back on the monte, started thinking, wow this looks familiar, so i grabbed the old one tried to thread it on, and it did. that was the last time i used the tiny ass stock one.

I run 0w-40 in my Regal and it's quiet. :)

 

Don't worry, as long as you use a quality oil filter your'e safe from lifter tick..

 

I agree. I use Amsoil Series 2000 Synthetic 0W-30 with an Amsoil filter, and my 3100 is pretty quiet.

Its not the lifters that are making that noise... This subject has been covered by GM in a TSB and is the result of the wrist pin and the piston having the maximum/minimum clearance. Only way to fix this is to get new wrist pins/pistons....

 

If your engines makes that noise even when warm, then you have a more serious problem that needs to be addressed.

i still run pennzoil platinum 5w30 and fram high mileage filter. when i first looked at buying my cutlass 5 years ago it made the ticking when cold but it only lasted like a minute. 5 years later and it still runs flawless. . i dont even notice anymore lol.
