Tappet Noise?

[jemezcrusher]

I have what sounds like lifter noise until the engine completely warms up (10 minutes or more) then pretty much goes away. I have run the valves and had to snug a feew up and thought that would quiet it down a bit. Zero change in the level of ticking. Cruiser Dan said that it could possibly be loose torque converter bolts, so will check that out soon. Thing is that the sound seems to be strongest underneath the dricvers side, right about where the little cat is.

Anyone experienced ticking noises coming from these?

could it be an exhaust leak? Use a piece of tubing as a listening device. Put one end in or near your ear, and move the other end around near the engine, exhaust flanges, etc. Listen for when the sound gets loudest...

Sounds normal to me. My 60's valve-train ticks like crazy until warm then quiets right down. One other possibility could be a broken piston which will get quieter when warm.

Thanks. Bought one new in 89 and was much quieter. Only 110 on the clock so will keep searching

Since you have checked your valves, check your timing.


Does it ping when above 2,500 rpm when warm?

I have an 87 fj60 with 190 on the clock... I am getting a tick on the lower part of the motor and to me it is a wrist pin that is doing this...if so i can rebuild now or let it ride and hope it doesn't score the block when it goes. there are severel things that could cause this and usually on cruisers it is the valves needing adjustment! Good luck!!

Does the noise vary in intensity with throttle/load? Or does it stay constant?

He could have his valves set too tight.

I have never seen a wrist pin failure in any engine that wasn't tuned to race potential. I doubt that you have a problem there. Since Cruisers do not use hydraulic lifters, it seems odd that you have noise for ten minutes. Even ten seconds is more than it takes for an engine with hydraulic lifters that have "bled down" to stop ticking. I makes me wonder if your motor is so sludged that the oil passages are restricted. It may be time for a serious Sea Foam treatment, or even ATF which is highly detergent.

I had the same type noise - still do to some degree. The first thing I did was re-torque all of my manifold bolts. They had worked a bit loose, and there was a leak tappit coming from there. It quieted down significantly. I still have a moderate tap, low on the DS, and have tracked to a split exhaust pipe just in front of one of the cats - I am guessing this means that cat is cooked and back pressure and heat are building up in the pipe, wihich casued the split. New exhaust is going on soon...

All that being said, I would recommend checking the manifold bolts and the exhaust.

I also have a sneaking suspicion it is tied to the exhaust, as it does not seem to come from the rocker area, and really quiets after 10-15 minutes of running

I miss read your first post. I thought that they did not start making noise until it was warm.

I sounds kinda normal.

What is your oil pressure and what weight oil are you running?

I also have a tappet noise in my truck after doing the "farm rebuild" on my engine. I had the head at the machine shop and they replaced some of the valves but not all of them and they did a 3-angle "valve job". I think they also replaced all of the valve guides. At first I thought the tapping was a wrist pin and piston slap but now I am thinking its a sticky valve or lifter. I recently got a stethoscope at A-zone for 10 bux.

In my case the noise is not there at cold start until after like 10 minutes...as if it takes some time for the cold oil to be squeezed out the sticky region. You can not hear the tapping at idle without the stethoscope. When you speed up the engine then you hear the tapping. When probing around with the s-scope the tapping is loudest at the top of the head just over number 1 cylinder. After driving on the highway the noise subsides when the oil comes up to temperature but with the s-scope you can always hear it.

I'm using mobil 1 10w30 synthetic and I have great oil pressure.
