Finally got the truck out on the road. Man the automatics are sucked out

Takes me forever to get up to 70 mph (100kpm). but enough of that, my question is about the solid lifter issues.

I am using 10W30 oil, just changed last week. There is a fairly loud tick, especially under load (normal driving) until the motor heats up - 5 min's or so. After that it is just the normal "toyota tick"

Do I need to run a heavier oil, or do the valves need adjustment (only for cold start ups.... )

Thanks
86smiley ... I'll have to get some pic's of the new box on the truck. Actually looks respectable now!

You could start off by adjusting the valves, that wouldn't be a bad start

Yep, a quick adjustment and you should be good.

yeah ide adjust first then if that doesent help a thicker weight oil will most likely cure it, heard of people runin 15-40 rotella n such in 22-R's with good luck

Well, a thicker weight oil isn't going to do much for a valve tick.

But you say it sort of goes 'away' when the engine warms up but ticks louder when under load. That it ticks louder when under load suggests start looking for a leaking exhaust manifold gasket next to a cylinder or at the PAIR manifold bolted to the exhaust manifold. As the manifold warms up, it will expand and put some extra 'oomph' against the gasket, causing it to seal better. It may not go completely away though but will be quieter under part-throttle and deceleration and louder under acceleration.

If the engine has cooled down for a couple of hours, The louder tick is there after startup. It is definately noticiable if I start driving right away (very light pedal). After 5 min the noise is basically gone. (idleing or driving....no loud tick)

The best way I can describe it, it's like when you have hydralic lifters, and they have drained down and need to pump up again to operate properly.... IE . Lifter Tick.

But since this is a solid lifter system, I was told it has to be taken care of by doing a valve adjustment procedure..... Totally different from a hydralic valve adjustment.

??? Not sure if that made sense ???

Makes perfect sense... but is wrong. Hydraulic lifters are sensitive to oil weights and temperatures but solid lifters aren't. Solid lifters don't rely on oil and check valves to take up clearances like hydraulic followers do and as such are slightly less susceptible to temps... not that temperatures don't effect clearances though, but nothing that would imitate being somewhat quiet at idle and loud under throttle.

True that metals expand and some clearances are taken up, but a noise that becomes louder when on the throttle isn't a lifter clearance issue: it is caused by exhaust gas escaping around a gasket. Under light throttle (after warmed up) maybe a light 'tick' but on the throttle there is more fuel and air and consequently more exhaust to get out of the engine hence an increased 'tick' volume in those situations.

Thanks for the input. I will check the exhaust manifolds tomorrow.

My various 22RE engines have always made more valve-tick noise in the intermediate periods between cold and fully warmed up. That includes after the truck has been run, then sits for a few hours(in warm weather.)
