22RE RV Cam adjustments

I just installed an RV cam in my 86 toyota pickup, 22RE, carbureted.
I am not getting any boost in power.
Is there some trick to adjusting the carb, timing, or valve gaps?

I installed a new head, and entire front end.
Timing Chain, Oil Pump, Water pump Timing Chain Cover.

I gapped the valves to the standard 0.008" intake and 0.012" exhaust.
Set the timing to 0 deg TPD.

I then regapped them after 2 weeks.

Standard NGK Plugs.

I am not trying to make a wall crawler, I just thought I should notice a
difference.
The engine runs smooth and does it's job.

This is a 2WD hybrid truck.
It has the entire rear end from a 86 4WD Toyota, so I have 6 bolt rears
and 5 bolt fronts.

What did you use for a new chain? Did it have two different sets of marks?
You may have to advance your timing a little. How big of difference is in
both cams?

I simply replaced the chain, guides, tensioner and both sprockets, with
factory spec new parts.

The marks are immaterial.
I have done 4 head gaskets on 22Rs in the last 2 months.
Once you have done a few you realize that with the main crank shaft set
"spline key up", lower sprocket mark down, the engine at top dead
center, the mark on the top sprocket mark should be a few degrees to the
left (passenger side).

I tried that and didn't gain anything.

Not sure.
The RV cam was a gift from a friend who tried it in his 4WD briefly.
It didn't give him enough power boost, so he went up to a level 3 cam.

It is supposedly the stock cam for toyota commercial chassis', factory
flatbeds, Chinook RVs and Uhaul trucks with 22R motors.

From what I can find on the web, no engine modifications should be
necessary to use an RV cam, but there is no info as to how to tune to
one.

I used to have the same problem, i put a new crowel cam to my 94
4runner 22re but most of the mechanic do not know how to ajust the
timing because they need a special method to do it, so try to find
someone with that special tool. Hope u solve your problem.

I emailed both dealers selling 22R RV cams on Ebay, and one emailed back
to change the valve lash from 0.008" intake and 0.012" exhaust, to
0.007" intake and 0.009" exhaust.
I reset my valves last night and ZOOM... BIG difference.
Lots more power.


I will let you guys know how it turns out.

I reset my valve lash to 0.007" intake and 0.009" exhaust, and
ZOOOOOM....

The truck is much happier.
Lots more power.

Warm.
I am not enough of a masochist to adjust them hot.

I am pretty happy with how the engine is running now.
It misfires a little at idle, but at rev it runs smooth.

Now I just need to do the clutch so I can take advantage of all that
torque.

Liar. ;-P I know you own at least one pair of welding gloves, pick
an old throw-away pair that you can get some oil on.

Duh! You just put in a high-lift cam, of COURSE the idle is going
to be a bit lumpy. You want smooth, you leave the factory bump-stick.

Do NOT go for the Mega Race Super clutch - all you'll get is
thrashed main bearings. The thrust bearing on Toys isn't all that
robust, you'll just shove the crank out the front of the block.
Someone just had that problem here a few weeks ago...

The stock clutch will work just fine, as long as you don't slip it
too much. Dad had several Toyota Dolphin Class C motorhomes with
R-motors and all special-ordered with sticks. All were loaded well
past the original GVWR with 'siamese' dual wheels and tag axles.

He drove them ~100K miles each for work (the break-in period) with a
lot of hill-climb trips over the Grapevine and to Vegas, and then sold
them private party. And never once had clutch troubles.
