oil change gone bad

Whenever you can, slowly take your time to do the other items, i.e. pcv valve replacement (cheap/easy), EGR valve (cleaning), fuel & air filters, as well as checking your spark plugs - these too, can cause a noisier engine if it's not breathing/running well.

are you saying doing those things will quiet the hydraulic lifter tick? if so, i can't see how. it's an oil/hydraulic issue, nothing to do with the other stuff.

maybe by making the engine run a bit smoother the regular engine sounds might be a bit smoother and thus apparently quieter, but i doubt you'd even notice. now all those things are good to do, but. . .

Trooperbc - you're reading too much into it; I did not say that it would specifically quiet the lifter tick, I did say that if the engine is not breathing/running right it will cause it to be noisier in general.

Then again, you can't guarantee his "tick" is oil/filter related; that's what I thought for some time too on my engine that had never ticked before - then I had the waterpump failure and changed out the whole timing belt package.

Trucks quiet as ever now.

i listened to mine again and you really cant pinpoint where the sound is even with a stethascopeit sounds like the front,the middle and the sides. to me it sounds like loud injectors.i was wondering if the half timing cover on the pass side was removed if i could tell if the timing conponents were faulty. maybe cause i cant pinpoint it it wher im not looking,hiding down in the front somewhere. i do have a rattle/rumble noise at about 2500 rpms and quiet after that.but other than that it runs great.

actually i'm not, i'm reading what you wrote. and asking you to clarify.
thanks.

i do think the hydraulic lifter tick is an oil/hydraulic issue, which is what i wrote. i do not think it is an oil filter problem, as some others do. as to what you solved, i don't know.

After re-reading my sentence in that one post, I do understand where you're coming from. Sorry, I didn't mean to suggest that those items would resolve the ticking issue, only that cleaning/maintaining those items would help it breath better, thus they would quiet other areas of the engine down - just not the "tick".

I'm not 100% sure what I believe in as to what causes the tick, I only know that mine only ticked between 144 - 152k miles; at the start of the tick, I ran two cycles of Rotella synthetic diesel oil which quieted it down incredibly - probably only because it was a thicker oil, cushioning the sound in the lifters.

However, at 157k miles, my waterpump failed, in which I replaced all timing belt components, and then switched back to a thinner oil last winter, 5w-30, followed by returning to my normal of 10w-30 this summer.

My tick was completely gone the SAME day my new belt/parts were put in - so it is VERY possible that mine wasn't actually the infamous "Isuzu" tick and may have only been a sign of the waterpump failing.

It's too coincidental that the sound developed just shortly before the waterpump/timing belt tensioner failure and then completely ceased following replacement.

I am the original owner of this truck, and the noise I heard before the previous parts failure, was a noise I had never heard in 10yrs of owning it and running Havoline 10w-30 every 3k w/Isuzu OEM filters.
