solara v6 makes valve noise at first start up with amsoil

[andrew224]

its a 2000 solara extremely well maintained with synthetic oil its entire life every 3-4k miles, decided to go with amsoil 5w30 since they say its the best. amsoil recommends using their engine flush cleaner to help clean the engine a little to make it a fresh start, they say its safe to use every oil change , didn't make oil any dirtier after use drained oil and put in new 5w30 and filter. started it up and it made a rather noisy valve sound , about 10 seconds and it quieted down to normal. started the car up during the day after using it once and no noise. the car doesnt get used very much only ran 50 miles since change because im nervous to run it like this. wondering if it's got a little of the flush still in it and made the already thin amsoil thinner making the valve noise or is it just the amsoil . I dont think the flush caused it because the engine wasn't dirty to begin with, hope the engine isnt hurt. any help or anyone had this issue before would be helpful.

Maybe the filter or top end didn't fill up with oil fast enough? I'm not sure.

Its regular. When you install a dry filter it takes a while for it to fill up and the top end to get oil. A trick is to prefill the filter but its impossible to do on the camry since its mounted horizontally.

Now if its doing it everytime you start it after sitting the anti drain back valve on the oil filter is junk and dont use that brand of filter again.

thats the thing i always pre fill my filters before installing them , like i said in the post it did it a few times after the oil change after sitting for a few days. Replaced the oil filter today and the noise at first start up is gone , but not to happy with the noise the commonly thinner viscosity of the amsoil makes . read posts and its sounds like amsoil is a thinner 5w30 than any other oil which causes more valve noise. it was a wix filter that i believe was faulty.

so the anti-drainback valve on WIX filter was letting the filter get dry and that's what caused the cold start valve chatter ?

I would guess there very thin chance it's the Amsoil causing it, it's considered a very good oil (manufacturer claiming the best, even better than Mobil1 which I like and use).

I had one Purolator Pureone filter which was getting dry after a few hours, same problem, ADBV was faulty/leaking on it. when I removed that filter from engine it was dry inside, no oil in it, zero spill while removing it.

No oil leaking out when the filters taken off doesn't necessarily mean the drain back valves bad. If you puncture the valve there's still a good amount of oil inside it between the can and paper media.

[fenixus]

true, but I used those same kind filters a few more times and always had at least some oil spilling out, only except for that one time when everything was completely dry.
forgot to mention that I had some cold start valve chatter problems too back then (5s-fe engine) that I was relating to my first use of Penzoil Platinum oil, was wrong obviously on that assumption

tryed it after a few days sitting and no noise , crazy that in 10 years of working on cars that this is the first time i got a bad filter , and would have never exspected it to be a wix filter to be bad. They claim amsoil is a little on the thinner side , called amsoil and they said 5w30 is the same thickness no matter what the brand , but who knows why theres a little more valve train noise , i think its a little bit of the flush still in there might have thinned the already thin oil.

[andrew224]

to make my story even more odd , drove car today and the "insufficient egr flow" code is gone. and its been on for about a year.

A 5W-30 is a 5W-30, regardless of brand the viscosity doesn't change.

AMSOIL has fantastic film strength. Which AMSOIL synthetic motor oil did you use though, the O.E. line, the XL line, or the Signature Series? I'm wondering because the O.E. line is for standard drain intervals and the XL line is for up to 10,000 miles and the top dog Signature Series is for up to 25,000 miles, whereas the Wix oil filter is designed and recommended for merely standard drain intervals. The AMSOIL absolute efficiency oil filter is considerably better than the Wix line and is good for up to 25,000 miles making it a perfect match for the Signature Series line.

BTW thinner oil should aid with startup noise. a Thicker oil will be even worse at startup as oil thickens as it cools. This makes it harder to get to the top end of the engine after the car sits for a while. This and a properly functioning filter assure no dry starts.

Hmmm, what about in a 5SFE? I always noticed it in my car, but did not pay too much attention to it. I've used different oil filters all having the same results. The car starts and for maybe one or two seconds it will sound slightly dry on the valves in the head, but then you hear it quiet as the oil pressure comes up.

Sure sounds like an oil/lubrication issue. What brand/viscosity and type, (petroleum or synthetic), oil are you using?

[JimBowNut]

So.......Did the Amsoil fix your egr problem you think ? lol

[Scott O'Kashan]

Unlikely but possible. Top shelf synthetic oils burn off at a much, much lower rate than dead dino oils do, which can greatly reduce carbon build up inside the engine or EGR valve.
