1991 Hilux 22R timing issues


Recommended Posts

Hi, I am new to the world of toyota as well as this forum.

I recently purchased a 1991 2wd Hilux SR5 running a 22R carby engine. I have gone through the usually maintenance when purchasing a vehicle, new plugs, leads, filters, oil etc etc,

Since purchase she hasn't run perfectly, I bought a haynes manual and I have been going through it to get her back to where she should be.

few issues I have found that I would love some advice or help with.

1. I have gone through the timing procedure as per the manual and cant get her to time correctly. When the rocker cover was removed and i manually turned the engine to get cylinder 1 at TDC on the compression stroke as per the dimple on the camshaft sprocket, the timing markings on the on the crankshaft pulley dont line up. the mark on the pulley is about 25mm to the right of the '0' mark on the timing plate. Im confused why.......

2. I have adjusted the valve clearances as per the manual but the valves still seem to be noisy, im assuming it has to do with the above problem.

3. Apart from the tapping from the valves shes and drives ok, but under hard acceleration she runs out of puff at 4000 RPM and backfires when changing gears (manual gear box) is this all related to the above timing issue or is there something im missing.

If you need anymore info please let me know.
